I’ve been setting up a new office PC with Windows 10 (while checking out the security and privacy settings, which have been well covered elsewhere). Briefly, the Windows 10 Print to PDF support doesn’t allow custom page sizes as it comes, but there is a simple way to enable it. Just in case it helps some others until this is fixed, I've found a work-around for this problem by writing a small script that imports a PDF and produces a PDF with an integer document size (screenshot from Mac OS Preview below).I don’t usually post Windows tips and tricks, but I thought this might be useful as I haven’t seen it mentioned anywhere else. This 0.1mm document size error has been quite frustrating today since it results in graphics that are slightly and noticeably out of alignment (the width and height of the imported assets are inferred from the PDF document size) Thank you Dan, it is a very helpful tip that the precision of numbers in the UI can be increased.Īlso good to know this bug will be addressed in a future version.įor context, I'm using PDFs from Affinity as assets to generate dynamic PDFs on a web server (PHP & FPDF/FPDI). So why not write them exactly as set in Publisher ? I guess in PDF the values for page, trim, bleed. Nontheless this is not really satisfactory 😐 It would really help to get the right PDF output without hassle. So, setting the appropriate document resolution for the right media target seems to be crucial. After exporting the document again the discrepancy shrinked to a small amount and the failure is no longer visualy significant. What 'fixed' the problem for me was, to set the document resolution in publisher to 300dpi. As Walt mentioned this might be the result of internal unit conversion and/or rounding. With the Acrobat preflight you can see that the resulting page size differs a lot from the original page size. On the right and bottom side there was a little white background shining through.

This was obvious because of the black outline.

This resulted in a significant difference of the resulting document size in the exported PDF. So the document resolution was only 72dpi (template default). What i forgot was, to set a really high resolution for this document which was intended for printing.

The document units is Millimeter and the page size is set to 80 x 69mm. I just encountered a similar problem in the actual windows version 1.
