Recently I have started setting a magazine and get info from obscure places and the preflight panel has been wonderful. It tells me what application has been used to set ads – yes even powerpoint. my goodness.
BUT when an ad is being set correctly in InDesign and the images are all good quality and it is being exported as press quality pdf, it will give an obsure reading in the preflight panel of Effective Resolution eg 164dpi.
What is happening here?

Apologies if I don't understand, but is the problem that the image in question is better than 164 dpi and it's a false reading? Or that 164 dpi is acceptable for high-quality and wondering why it's being flagged as not acceptable?

Hi docbud
The images in the InDesign files are at 300ppi and the pdf was exported as press quality. I did this one myself so I know that I am getting an incorrect reading. The question is why? Other pdfs created in InDesign and exported in the same manner are OK.
I am an advanced user, so I am hoping it is nothing silly. But double checked images in InDesign. The high res pdf was then placed at 100% in InDesign, and the Effective Resolution in preflight shows as 164dpi.

Hi Ketrinz :)
I gotta say it's hard to figure it out at this point. Any chance you can post the file in question so folks can take a look at it? (I know that may not be possible, as my company has a no-no policy on such things for legal reasons).
I don't normally place PDFs within ID so I'm not sure.
Hopefully the experts will jump in :)

Worked it out. I think it was Sandy Cohen who mentioned something in a post that I can't find now. Thanks anyway to whoever it was that mentioned “a link in Illustrator with transparency that would be causing an issue”. Of course it would raster it. That was the only one that I had scaled. Will keep an eye out for that one with other files that I have seen this message with. It was good to do it myself (by accident) I now know the issue instead of freaking when I see the low res image warning and making the client double check and recheck the raster images in the document. I had this message previously when placing an ad from a client and it printed OK. I just love the Preflight panel and use it as much as possible. Thanks for joining in docbud.

Glad you got it worked out, Ketrinz.
