RE: [PDF] RGB photos

[Janine Hannel]

If I understand correctly, you're getting some gray where there should be white. Before you send your PDF off to the printer, bring each page into Photoshop, open your info palette, and run the eyedropper over  the background of each that should be white. Where you get a K value, you have to remap it to white.

We ended up printing as a composite gray just to get the job out but we started picking up background tints on some of the RGB images (about 10% screen). The department was OK with the quality so we printed. But we need to resolve this issue when we're not in crisis mode and be able to respond next time.

This seems too simple. What am I missing?

 

Why not print it as a composite gray? If you are placing the file in a black and white document, you can always redistill it.

Subject: [PDF] RGB photos

We have PDF file created from Pagemaker 6.5. The PDF needs to be greyscale for printing purposes. Most of the images in the PDF are RGB. Is there any easy way to change all the photos in the PDF to grayscale without going back to the customer and making them convert all the photos in the original Pagemaker document?
