Grey Frames around cut out images when exporting as a print pdf

[kdvklaus]

Hey guys,

I have a problem. I want to create a pdf document for print with two cut out images on a yellow background. When I export it and open it with preview on Mac there is a grey frame around the casio watch. The citizen watch doesn't have one. Is this a problem with Preview on Mac or is there way to edit the casio picture? I want to print a book with a lot of cut out images, where this happens. I'm concerned that they will be visible in the final print version. I upload the pdf, the settings and the affinity publisher file. Does anyone know the solution for this?

Best regards

Here is a screenshot when I open the pdf in Preview on Mac

In Acrobat I don't see this rectangle (it is the size of this layer's bounding box) but in Apple's Preview, I assume it is an issue of Preview with the transparency of this layer, and/or with PDF/X-3. (If you need to avoid the occurrence in Preview you could export as PDF 1.7 or rasterize / merge the watch with the background.)

Thank you for your comment. That makes sense! I will contact the printing house and do a printing test.
