Lagarto, Never mind! I just found the Add option for adding a layer. Thanks again for your assistance.

Lagarto, I follow you with regard to the vector crop tool. However, I don't understand how to append a layer ID.

Lagarto, Great information. Thank you.

Lagarto, Thanks. I looked at your retest.afpub. I don't understand why the bottom image was upscaled but the top image was not.

thomaso, When I tried this I got a different result. I placed an image at 100 dpi into a blank page and exported as PDF/X-1a:2003, 300dpi. Opening the resulting PDF in both Affinity and a third-party app, the image dpi is shown as 100. Is there a setting that I missed that resamples ("up samples") the image at export?

v_kyr, That is what I have always done, but I received a new job that had been started by someone else. Oddly, all the images in her file are at 100 PPI. I will meet this person tomorrow and discuss this issue. Thank you for your assistance!

v_kyr, So, are you saying that if the placed PPI of an image in the project file is 72, and I export at 300 PPI, then the image in the exported PDF will be at 300 PPI?

IngramSpark requires print-ready PDFs be exported at 300 PPI. But IngramSpark's guide also says images of 72 PPI are acceptable! To me, this is confusing. If the export is at 300 PPI, shouldn't all images be 300 PPI too?

Ever worrisome is The Guardian: The agency’s investigation “will have global reach”.

If I have only 8GB RAM and I am working on a large, image-heavy file, how should I set "RAM usage limit" to give me the best performance? At 8GB? At something lower? Or would this setting make any difference to performance?

Eze, I successfully met the printer’s requirements simply by increasing the bleed. Widening the bleed also moves the crop marks out. Here is part of the printer's requirements: PRINT AD FILE SUBMISSION GUIDELINES • Press Optimized or PDF-X-1A PDFs are required. • If an ad is intended to bleed, crop marks must be applied with an offset of 0.250”; a minimum of 0.125” bleed beyond the trim is required. The printer specified the bleed as a minimum.

Thank you, Joachim. You have a good idea, but unfortunately it would not do what is necessary. See the example of word stacks that I have attached. They can occur anywhere but are particularly noticeable at the end of lines. My client just discovered word stacks. If she wants me to correct them, I'll go through her book manually.

Can Affinity Publisher preflight find word stacks? I have heard that scripts are available for InDesign for finding word stacks. Is anything similar available for Publisher?

Gabe, I have made some progress in diagnosing this problem. I have discovered that the image problem (low contrast) happens only when exporting using PDFX-1a:2003 or PDF/X-3:2003. When exporting using PDF 1.4, 1.5, 1.6, or 1.7 the problem does not occur and the images have the proper (high) contrast. My printer, IngramSpark is recommending exporting using PDFX-1a:2003 or PDF/X-3:2003. I don't think I can do that. Do you know why PDFX-1a:2003 or PDF/X-3:2003 cause this problem but not PDF 1.4, 1.5, 1.6, or 1.7? Thanks.

Gabe, Thank you! I uploaded the project file, with resources embedded, plus one sample resource.
