I am allready writing a degree in Graphic technology about PDF/X standards and differences between them. I made my own test form to compare different PDF/X standards and different print devices. I have exported differend PDF/X standards from Adobe Indesign CS3 and then I have printed them on different printers (digital printers). Although I was looking for many answers on the internet I didn't find out why there are differences between standards in LAB (differences between PDF/X-3 and PDF/X-4, as I traved an information which mentioned that PDF/X-3 and PDF/X-4 interpret LAB colors in the same way). I also find out that PDF/X-1a and PDF/X-3 are smilar and PDF/X-4 and other presets in Adobe Indesign (such as press quality and high qualilty print) are similar too in interpreting the LAB colors. I just didn't find out why. The same problem happened with overpint. Only PDF/X-4 and high quality preset were printed suitable. The PDF/X-3 and PDF/X-1a didn't recognize the overprint. Similar happened with pictures (one in CMYK and the other in RGB color space).. PDF/X-3 made them really similar while PDF/X-4 made RGB printed pictures much more bright instead they have the same setting about converting colors during export. Is it possible to explain this with differences between standards or it depends on the settings of the RIP? I will really apreciate any answer you could give me. It wiil be very helpful.

I do not recommend people actually spec their color swatches (such as type color) as RGB unless they're creating for-screen-only documents. (There is some rationale for speccing colors in Lab, but it's not for the faint of heart.) PJ, in general when I talk about RGB workflows, I mean importing RGB images into InDesign.

Like PDF/X-3, it supports both CMYK and RGB workflows. With that said, I'm not sure you're up-to-date on how the CS2 and CS3 application handle RGB and CMYK. Beginning with Creative Suite 2, color management has a "safe CMYK" workflow. The color management default in the CS2 and CS3 applications is safe for CMYK workflows because it preserves CMYK colors across the workflow. C MYK values will NOT go through an "RGB filter." PJ,

It has been my experience that when black goes through an RGB filter, black separates to C;75 M:68 Y:67 K:90. That's a bit heavy for a supported or rich black. Suppose the document is supposed to print K+300 as a two color newsletter. Black isn't at 100%, most likely, the customer will reject the file if it gets printed. What happens if the designer is not available to correct this? The file was sent in and he took off for Christmas vacation. Been there done that, and tricked the file into printing black + spot color seps, after an hour of thought and an hour of trial and error. I documented the process, because I've had to use it more than once since then. This may not be a big deal for large printers with all the newest equipment, but it will be for the quick printer around the corner. The RGB workflow can spell trouble for going to press.

I opened up my copy of QuarkXPress 7.2 and created a page with transparency. When you choose File > Export Layout as PDF > Options > Transparency, you can now set the resolution for Vector Images, Blends and Drop Shadows. (That is new, there was no control for this before.) There is a checkbox called Ignore Transparency Flattening, but this strips out all transparency from the objects. I can see no way to retain transparency in the PDF. Mark is correct, as far as I can tell. David,
