Creating PDF: Export or Use Distiller?
September 22nd, 2006In last week’s post I discussed how using InDesign’s Export Adobe PDF feature and PDF presets make it quick and easy to create a PDF for a particular workflow—commercial printing, a desktop printer or the web. But you may work with a printer who insists that you shouldn’t send them directly-exported PDF files. Instead, they say that you should create a PostScript file and process it through Distiller. Why do they ask you to do that, anyway? Is it really better?
Before I answer that question, let’s look at the alternative method your printer is suggesting. In InDesign and all the Creative Suite applications, it’s easy to create a PostScript file from the Print dialog box. Just select PostScript from the Printer menu at the top of the dialog box. Then you can choose a PPD file (I’d suggest selecting your Adobe PDF printer if you have Acrobat) or Device Independent (removing any printer dependencies, useful for some postprocessing workflows like imposition). Make your choices in the Print dialog box, and then click Save instead of Print to create a PostScript file. You process that PostScript file in Distiller using the PDF settings file your printer suggests.
It sounds like a lot of work doesn’t it? It’s two long steps instead of one short one.
Not only that, but you’re going to lose a lot of information when you make PostScript instead of directly exporting PDF: Because PostScript is an older technology than PDF, here are some things that will be lost:
- Transparency is flattened.
- It’s not possible to create PDF layers, useful for versioning, for example.
- The file’s structure (called tagging) is stripped from the file. (I discussed this in my post on Creating Accessible PDF Documents).
- Forget about a color-managed workflow; embedded color profiles are discarded.
- Interactive elements (bookmarks, hyperlinks, etc.) are thrown away.
So why does your printer suggest this? One possibility is that your printer may have had an InDesign directly-exported PDF file fail on their RIP because of a PostScript error. (Techie alert: If the rest of this paragraph makes your eyes glaze over, just jump to the next paragraph!) Your printer may have an older RIP (raster image processor) which doesn’t support font encoding called CID-keyed or Identity H, which was used by InDesign CS and earlier when it created PDF files. This font-storage method has been part of the PostScript specification for over a decade but some older, non-Adobe RIPs don’t support it. This method is necessary to store some fonts with a lot of glyphs like OpenType fonts. Actually, it’s pretty likely your printer just hasn’t forked over for a RIP upgrade since all modern RIPs do support CID-keyed fonts.
The good news is that InDesign CS2 no longer embeds CID-keyed fonts by default, so its directly-exported files are smaller and more compatible with older RIPs.
But another reason your printer may resist is just fear of the unknown. Many printers find it easier to stick with the tried-and-true Distiller method than experiment with something new. (Some of them also still refuse to accept TrueType fonts!) So if you can’t get your printer to try your directly-exported file, you should at least use Distiller faster by choosing the Adobe PDF printer. To use this, you need a copy of Acrobat 6, 7, or (in a couple months) 8 Professional.
Here’s how it works: (I’m describing it in Mac OS X; it’s similar in Windows.) Choose File > Print, and select the Adobe PDF 7.0 printer (or the version that matches your copy of Acrobat). This printer uses Distiller in the background, and uses exactly the same settings files as you’d choose in Distiller. Make your usual choices for printing. To get to the settings files, click the Printer button at the bottom of the dialog box. Ignore the warning message or turn it off, and click OK.
You’re now in the Mac OS X Print dialog box. In the menu that shows Copies & Pages, select PDF Options. You can then use the Adobe PDF Settings menu to select from all the PDF settings files (presets) you’ll find in Distiller. When you click Print, you’ll be given an opportunity to save a PDF file. The Adobe PDF printer will take care of creating it.
But, by all means, use the direct export method if at all possible. It’s more efficient and faster, and it can include all the elements that PDF is capable of handling.
I’ve been reading this site for a long time now and this is the first time I have to disagree.
Sending non-flattened layer pdf’s to your printer is an accident waiting to happen. I would advice to your own flattening and see for youreselve what happens in the PDF. Furthermore, exported PDF’s from CS ans esp. CS2 can and will cause problems in the PDF workflow when processed by ‘InPosition’ software. i’m out of time now, but I’ll get back on this later. Regards, Woz
Woz, there is no doubt that some imposition (and other post-processing) software breaks with PDF files that contain transparency or layers. That happens because those programs are old and do not support newer versions of PDF.
For example, if you are going to import a PDF into QuarkXPress 3, 4, 5, or 6, I would definitely not consider using anything except the flattened Acrobat 4 format (also confusingly called PDF 1.3). Actually, I prefer using EPS files for those versions of QX.
Woz,
Read my previous post on this topic (Choosing the Right PDF Preset), and you’ll see that there are built-in PDF presets like PDF/X-1a that do flatten transparency. It all depends on what your printer’s workflow needs.
However, the direction of the technology is to keep transparency unflattened, and have it flattened at the end of the process. If your printer ever upgrades his early 1990s RIP, he may get a RIP where the transparency can be kept natively.
Ultimately, the prepress professional is the best person to do the flattening by making the proper choices at print time. But most printers aren’t there yet.
Steve,
Excellent summary, which I appreciate very much. I thought I read a few months ago (probably from a comment by Dov) that CS2 tends to avoid Identity H CID-keyed fonts but may, on occasion, still embed them in the PDF that way anyway. Is that the case?
Mike Witherell in Maryland
Thanks, Mike, you’re correct about that. When you’re doing a brief summary you always have to leave out details. One detail I left out is that BOTH CS2 apps when the export AND Distiller will use Identity H CID-keyed fonts if they have to.
So those printers who are hanging onto those old, un-upgraded RIPs will still run into trouble with Distiller-created PDFs sometimes unless they break down and move into the 21st century.
Then my memory isn’t completely worn out!
Well said on that last thought about upgraded rips, Steve. And many thanks again for the article. I copied a few of your words into my teaching notes.
Best to you,
Mike Witherell
Hello, I’m back again.
@ David:
Problems happens with PDF 1.3 and inposition programs. Several large printers overhere in Europe have completely banned CS2 exported PDF files for this reason.
@ Steve:
I read your prevoius post(s). All the PDF’s I send out are PDF/X1-a compatible. I use Enfocus Instant PDF. In Europe we have use the settings from the Ghent Group: SheetSpotHiRes, SheetCmykHiRes (for example). Every PDF we send out is a certified one. We use altered transparancy flattener presets if we don’t know how skilled the printers prepress departement is.
And thats my point exactly: Flattening PDF files is something I would advice anyone to do themselves. The entire European PDF workflow was set up to be PDF 1.3 simply because to many printers use old(er) RIPS or because they do not really know how to handle this type of file.
If you work for a larger design agency and you have to set up a workflow, Distiller is the smartest option. Distilling will never get you in trouble. You only have to teach your people one way to work.
Yeah, so there arn’t any layers in the PDF but so what? Alle certified PDF’s in Europe are 1.3 and can’t contain layers anyway. It’s simply the safest choice.
Furthermore we work for international cliënts. Some of witch use their own printers in different countries around the world. Sending Distilled certified PDF’s ensures us everyone is able to establish a good finished printed product. And that’s what it’s all about. In the end the guy who pays my bill doesn’t care if I distilled or Exported. He want’s a good product.
PS: For the same reason I use a RGB workflow in InDesign. But what I send out is a CMYK (ISOcoated or uncoated or uncoatedyellowish etc etc) PDF. I will handle the translation to CMYK. And I will check it via my calibrated printer.
I felt I needed to add this in the comments because some poor DTP-er might think it’s okay to start sending out exported PDF’s and might get himselve in trouble.
PS: I love the site by the way. Your site is right up there in my bookmarks, next to www.indesignvsquark.com I host my own INDD/PDF/CS etc site, but it’s in Dutch…
Woz,
There are many different workflows. I’m glad your solution works for you, but it’s not the only workflow. I also like PDF/X, in fact recommended it in the previous blog. And that is where a lot of printers are now.
But Adobe has introduced the Adobe PDF Print Engine which will allow a lot of elements like transparency, layers, embedded profiles, etc. to be kept live throughout the workflow, and only will be rasterized at the end by the printer. I’ll write more about that on a future blog.
Best to you!
I can tell you that in my design studio, when we have a say over “who’s printing this,” (about 75% of the time) we seek out printers that accept live transparency PDFs exported from InDesign. We want them to be responsible for the flattening, just as they are responsible for the trapping. FWIW I’ve had no trouble finding commercial printers who do an incredible job with this. I’ve had printers tell me they prefer to flatten because that way the PDF is more editable when necessary (not broken down to atomic regions), and their settings are tweaked for their own equipment.
When I’m doing on-site training or working with a design client and they say that their printer insists on PDFX/1-a (which is supposed to be a “blind” standard, not for when you know the printer), I tell them to go to Adobe’s Adobe Partner Finder: Find A Print Service Provider, put in their zip code, and hit Submit. They get a list of local printers who are Adobe Partners and should be quite up to date with their RIPs. Then just go through the list, call them and check that they are experienced working with exported PDFs from InDesign, do they have any PDF presets they can send you, and so on. It’s worked wonderfully for dozens of clients so far.
Listen, Woz. If sending flattened PostScript files works for you and your vendors, great. But to insist that this is the only way to work is nonsense. The printing world has come a long way since writing PostScript, as others on this thread have indicated. In my business I always send PDF 1.4 (Acrobat 5) or higher files which support transparency whenever possible. Sending pre-flattened files is like sending pre-separated files; why would you do this when you have no idea what’s going to happen on the other end? Regardless, if you feel comfortable with your workflow and it produces acceptable results, then by all means keep doing what you’re doing. My point is simply to keep an open mind to other solutions and approaches.
@Scott: “Sending pre-flattened files is like sending pre-separated files; why would you do this when you have no idea what’s going to happen on the other end?” Sending out preflattened pdf’s is the safe-est choice. Every RIP can process them. Not every RIP supports live transparancy.
Anyway, thanks everyone for your reactions and thoughts. I feel InDesign has awakened the entire industry. There is a lot of attention now for so many new things: RGB workflow, cert. PDF workflow, transparancy, etc etc. Remember when all we wanted was a ‘multiple undo’ in that other layout program?
Woz,
Send pre-flattened PDFs may be the safest choice when you have no idea of the printer, but as the others have pointed out, it most certainly is not the best choice. I have personally refused to use a printer that demands flattened work since ID 2.0 was released. I’ve had no problems finding a printer that wants my money and for the most part my clients accept my recommendations for printing.
When submitting ads, I make sure to design accordingly to avoid any problems and send an exported X/1-a file.
Hello Bob. ‘The InDesignguy’, nice title.
Okay, you guys you’ve confinced me to at least start testing sending out PDF files with live transparancy. Does any one here know of an Instant PDF Queue I could use for this? The ‘usual suspects’ SheetCMYK en SheetSpotHiRes don’t allow it.
[…] Sometimes the relationship between creative professionals and their printers is not the best. My recent blogs point out some of the tensions. For example, Bob Levine wrote in my Creating PDF: Export or Use Distiller blog, “Send[ing] pre-flattened PDFs may be the safest choice when you have no idea of the printer, but as the others have pointed out, it most certainly is not the best choice. I have personally refused to use a printer that demands flattened work since ID 2.0 was released.” […]
On a somewhat related note: Is there a way to export each page of an InDesign document as a separate PDF (without having to do it page-by-page)?
Mark,
Do you have Acrobat Pro? If so export the PDF from ID and then use the extract pages command in Acrobat.
I have it, but my client wants to be able to do it. They only have InDesign. I’ll just tell them they need to buy Acrobat Pro.
It is possible in InDesign via a script. It’s a free script but I forgot the name. Just browse on Adobe’s site. There’s one for print-to-postscript’ per page. You can then distill every page and have a pdf for every seperate page.
I have to backup what Woz is saying here. sticking with 1.3 is the conservative (and Ghent WorkGroup approved) approach for working with a number of print suppliers. And it is by far the best way to minimise headaches if you want to have flexibility in print supplier (we print all over the world). Our rule is we do not make PDFs for specific printers demands. After all what’s so “P” about a PDF that you can’t later give to someone else to RIP.
Our experience is that we often know better than the printers what they can handle. If you ask “can you handle transparency (1.4)” they will say YES often out of ignorance or just wanting the work. Now they pay when they get it wrong, but we don’t get compensated for the delay.
And it’s not just a matter of RIP software being out of date. This year we discovered a bug in Creo’s latest RIP software that fails to use a feature from the 1.2 pdf spec! (pattern spaces) SO even modern rips have problems with 1.3 leave alone 1.4
We are working towards direct export to PDF from applications, but we’re not going to switch away from PS -> distiller -> PDF for a good year or so i bet.
(Great site BTW - bookmarked)
ps i googled by looking for something on overriding in distiller the flattening settings in AI eps files
I work in a prepress department with a pdf workflow. When I receive InDesign files (both Mac & PC) I export them directly from InDesign and do not flatten them as we have a flattener at the rip stage. We also import these files into our imposition program with no problems.
We deal with a wide variety of clients, from designers to the person working from their home computer. I tell the unsophisticated client to use “press settings” when exporting to pdf and they should have no problem. If there are transparency issues, I then contact the client direct them on how to save their files correctly.
D. Barr, thanks for posting. Can you enlighten us, from a printer’s perspective, why you ask for live transparency PDFs instead of flattened ones? What are the advantages?
I export, Distiller fails sometimes
Hi,
do you know if there is a way of modifing the preflight preferences in InDesign?
thanks
L/
Sorry, there are no preflight preferences in InDesign.
—It is possible in InDesign via a script. It’s a free script but I forgot the name.
Look for PageExporterUtility, in Adobe Exchange, Indesign, scripts. Will export either ps or PDFs, allows you to choose setting files, and will export as spreads or single pages, in the page range you specific. Very handy, simple, and reliable.
I’ve recently sent a PDF to a printer and had problems with transparent images being shown 100% strength instead of 15%. We tried to solve this but couldn’t. In the end we had to remove the images. There were also problems with the Windings font, which had to be turned into outlines in Illustrator before it was accepted.
I was told the problem was down to incompatibility between Macs and PCs. We use a PC, the printers use Macs. I’d have thought PDFs would have been compatible, but sadly not.
It was recommended that I print to Acrobat’s distiller instead of exporting to a PDF from InDesign, because “that’s the way you do it on a Mac”. However, I’ve always used the Export command before, as that makes sense to me. Why would I print to something that’s not a printer? That’s weird.
So I did some tests. What I found was the distiller GAVE WORSE RESULTS. When it came to a large image, even though I had upped the settings to maximise the quality, when compared to a directly exported PDF, the image was still showing compression.
I also had problems converting a document that had 2 A4 and 1 A3 page into a PDF using the distiller. It would put the A4 pages onto A3, leaving a blank space next to them. Whereas exporting directly coped fine. (I’m aware of InBooklet SE to handle pages better, but this seems too buggy to use. It messed up my layout and changed some of the graphics.)
In the end I had to redo the document as 2 A3 sheets. (Not sure if you’re always supposed to work this way or not!)
I also noticed that in a PDF proof sent by the printers that they were using Quark Express 6.5. So maybe it was that to blame for losing the transparency of the images? Or some other software they use to prepare the plates for printing?
I am also unsure what settings to use when exporting PDFs from InDesign. The PDF standard is set to “None”. Which option do I need from the following?
None
PDF/X-1a:2001
PDF/X-1a:2003
PDF/X-3:2002
PDF/X-3:2003
The Compatibility is set to “Acrobat 4 (PDF 1.3)”. It goes up to “Acrobat 7 (PDF 1.6)”. Now you folk are saying to use PDF 1.3. But are we seriously saying that printers are still using Acrobat 4??? Anyone using anything less than 7 is way out of date! Are they still running OS X 8 or 9? Hmmm.
Chris, you have been bitten by printerus ignoramus. My favorite (not) part of your post was where you discovered that your printer was placing your PDF files in QuarkXPress and printing from there. What were they thinking? Were they raised by wolves?!
QuarkXPress does not handle PDF anywhere near as well as InDesign. (It’s a bit better in QX7, but still…) In my opinion, no one should ever place a PDF file in QX4, 5, or 6 unless it is a flattened, PDF 1.3 file.
However, your comment about having both A4 and A3 pages in the same document. This leads me to believe that you’re using DTPtools PageControl plug-in. Yes? If so, you’ll need to work that out with them.
Re: PDF versions — Using PDF 1.3 (Acrobat 4) doesn’t mean that people are printing from Acrobat 4. It means that it’s a “lowest common denominator” version of PDF that even programs such as QX4 should be able to print. (Though I personally recommend using EPS files if there is any chance the file will be printed from QX4 or QX5.)
I only know the proof was from Quark. Beyond that…
A3/A4: no plug-ins, just InDesign itself. Which is the best page size to use?
Hmmm, after having many horrors using customer provided pdf’s with our AGFA ApogeeX workflow and also a few hiccups with our own created PDF’s. I now print postscript to a ‘watched folder’ with PDFX1a attached and an applescript that then moves the file to my desktop. One click, trusted output, simple!
When I export PDF’s in Indesign my printer claims that it is not converting the files to CMYK. He is receiving them in RGB. Are there any specific settings which I have not set yet?
How do I get Times Italic Bold to work. I have installed the font together with the italic bold and regular but the Italic Bold does nor appear?
font explorer works only for Mac is there one for PC?
Hi. I stumbled across this doing a search for some other PDF related information. I too work at in a Prepress Department. We’ve experienced different results than D. Barr. I have created custom PDF settings for each of the Programs that our clients use (including Distiller). All of these custom settings flatten transparency and are Acrobat4/PDF 1.3. We do this because it works. When transparency was still realatively new we kept running into problems. One of the first solutions I found was to drop the PDF version back to 1.3. Once I did that 98% of the problems disappeared. Additionally, we regularly update our RIP software to the most current version. However, just because your RIP manufacturer says it’s PDF 1.4 or 1.5 compatible doesn’t mean that you won’t still have hiccups. My experience has been that it takes serveral versions for the manufacturer to really get the support working correctly. All that being said I am currently planning to start testing PDF 1.4 files for problems. However, this change won’t happen until I’m thouroughly convinced that the 1.4 support works right almost everytime. It’s too expensive to reprint jobs for clients just because you want to keep up with the technology curve.
sam lee - on a PC, open the Printer & Faxes applet. (From the Start menu or Control Panel.) Right-click on the Adobe PDF printer listed and choose Preferences. Press the Printing Preferences button via the General tab. Select the Adobe PDF Settings tab and use the Edit button next to Default Settings. Choose Color and there is an option to convert all colours to RGB or CMYK.
[…] To save the layers for Acrobat, you need to directly export a PDF file. In the Export PDF dialog box, choose Acrobat 6 or higher compatiblity and check the Create Acrobat Layers option. As I pointed out in another posting, only directly exporting saves this information. […]
We often have to send our entire reports to cleints for revision. Hence we need to make the PDF file OK quality for printing but small in size to be able to transfer it or send it by email or FTP site. What settings should we be using?
When you say “make the PDF file OK quality for printing,” I assume you mean they’ll be printing it on a desktop printer. You could probably get away with 150 ppi for images. If the files are too large you could either break them into separate PDFs, or compromise on the image quality. You’ll have to experiment, there’s not a hard and fast rule.
Hey, I just stumbled across your page and I’m enjoying it. Thanks!
You said: “Your printer may have an older RIP (raster image processor) which doesn’t support font encoding called CID-keyed or Identity H, which was used by InDesign CS and earlier when it created PDF files.”
That’s what I keep telling people. Some printers keep saying that InDesign messes up fonts. No, that’s not the case. It’s the printer’s RIP that isn’t up to speed. That doesn’t mean that the printer is bad, but it would be good if some stopped saying that InDesign isn’t up to speed and actually got informed. I have had to explain to a few printers what their problem was myself, and I am a designer. Usually it’s the other way around, the printer has to tell the designer. Oh well…
How about a “Real World” check here.
I produce print ads for various publications from the New York Times to the local neighborhood weekly. All using different printers and prepress workflows.
And of course, this is all done on an very tight timeframe.
Producing a 4.0 (1.3) Acrobat PDF document using PS > Distiller is the only reasonable approach.
We make EPS files to go to Quark from InDesign. When I export to the EPS and then try to open it in Preview as a PDF, I get “File error. Couldn’t open the file.” and “PostScript Conversion Error. Couldn’t convert the PostScript file to a PDF file.” If it doesn’t work in Preview, it doesn’t work in Quark either. Some of my files work and some don’t. Any ideas??
If you can create a PDF from In Design directly without Distiller that will let you repurose it htta would be great.
I have found that IDD PDFs when downsamples for web are not searchable.
But if you use distiller for the PDF they can be downsampled and are searchable.
Any Ideas. Adobe says the fixed it, but still a problem is cid font.
http://www.adobe.com/support/techdocs/329611.html
*Please note that for Adobe’s Solution 1: Upgrade to InDesign CS2, we have found that a few fonts are still CID encoded and exporting directly to a PDF can result in the issues described above.
I have a customer supplying pdf version PDFX1a exporting direct from InDesign, the graphics go missing when viewed in acrobat 4 but are visible in acrobat 5, is it to do with OPI, any ideas?
This article series was VERY helpful as I am new to the professional world of graphic design/printing (did lots of it in high school and college). I have encountered my first printer who requires I use Distiller instead of exporting PDFs directly from ID and this totally baffled me because I didn’t understand the difference; but now I see why the printer recommends this method (they most likely have an out-of-date RIP).
My question is this: if I create a new preset in Distiller using all the settings the printer specified, is using that preset from within ID’s Adobe PDF Export menu the EXACT same as actually using Distiller? I guess I just don’t understand the purpose of Distiller as a standalone app if all its capabilities can be accessed from within the various CS apps. (I’m using CS3 if that matters)
Thanks for your time!
I am a huge fan of InDesign - haven’t used Quark in years. BUT a publication I’m working on now is using Quark 7 so I feel like I’m taking 2 steps back.
My question is How can I make Quark 7 import & export InDesign pdfs? Is it possible without distilling?
Pamela, I hate to be a bother, but if you want good info about QX, you’d be far better off heading over to PlanetQuark.com.

My friends PDF guru Stephan Jaeggi from Switzerland says that there are a very subtle, very technical differences between using the setting in Distiller and using the PDF preset in the other CS3 apps. But it’s so technical (and really so specialized), I’d have to dig out my notes from him to find it.
In truth, Distiller originated at a time when there WASN’T good export PDF option from applications (think QuarkXPress!). But some printers hang onto it because it’s worked for them in the past. (My opinion.)
Dave E said: “I have a customer supplying pdf version PDFX1a exporting direct from InDesign, the graphics go missing when viewed in acrobat 4 but are visible in acrobat 5, is it to do with OPI, any ideas?”
PDF/X-1 should produce flattened transparency, and should be visible in the same way in Acrobat 4 and Acrobat 5.
In fact, Acrobat 4 is getting VERY OLD and long in the truth. You really should be using a later version of Acrobat. The current version is Acrobat 8 Professional, and I’d bet there’s an Acrobat 9 not too far around the corner. It’s highly probably that if you can’t see something in Acrobat 4 it’s because of a BUG. Get a later version.
please help! I work for a newspaper, and every ad we do is exported to a pdf for every proof we do. The problem is that even though we never (or at least very rearley ever export the file as anything other thatn a pdf, we always have to go to the drop down menu and select PDF everythime. Doesn’t sound like much, but if you do this 300 time a day…!!!!! please, can anyone help, or can you point me to someone who can? Thank you
Ted,
That sounds like a great use for scripting InDesign. I’m not a scripter, but I’d head to the InDesign Scripting forum on the Adobe User to User Forums. It may be that someone has already scripted that operation. Worth a look.
Instead of choosing File > Export (and then choosing Adobe PDF), why not choose File > Adobe PDF Presets > and then choose the preset you need?
Ted, don’t forget you can also export a PDF based on a pdf preset by holding down the Shift key while selecting from the File > Adobe PDF Presets submenu. This exports the file without you having to look at the dialog box.
(Same thing works with File > Print Presets and File > Document Presets. Shift bypasses the dialog box.)
You guys rock! You don’t know how long I’ve been asking our IT to research this.
Thank you soooo much.
Ted
We are on Quark 6.
When we get pdfs from InDesign, most of the time we have to save it as a eps and run it through Distiller and it seems to work, but we have to do a lot of work to the pdf, because it comes over as rgb, however, when the client sends us the same thing exported as eps from the same InDesign job, it converts everything correctly. One of the main things is black appears on all plates for text, if we get pdfs instead of eps. so we ask clients to send both the eps and the pdf to us.
Hello, I just finished reading the whole thing. Instead of guessing, I’ll do what Anne-Marie has suggested and talk to the printer about my prepress options.
Thanks for all the information.
