Dear Affinity Users and Developers We’re just in the process of evaluating Affinity Publisher (tested with 220.127.116.115 and 18.104.22.1682) and we’ve come upon a problem with the PDF/X export: In our workflow our print PDF files are checked in Adobe Acrobat against the preflight profile PDFX-ready Sheetfed Offset Classic HQ V1.5. Among other things this profile checks the MD5 checksums of the used ICC profile against a pre-defined list of profiles known to be appropriate for offset printing. When exporting a PDF as PDF/X-1a with the ICC profile ISO Coated v2 300% (ECI) from Affinity Publisher the preflight returns this error: Looking at the preflight report in the section Output Intents I noticed a difference between a PDF exported from InDesign and Affinity Publisher: The Output Intent is stated as ISO Coated v2 300% (ECI) for the InDesign-PDF and as ISO Coated v2 300% (ECI) (Custom) for Affinity Publisher The Color Management Module had a value of HDM (InDesign) and lcms (Affinity Publisher). Primäre Zielplattform (in English probably: Primary Target Platform): empty (InDesign) and Apple Computer, Inc. (APPL) (Affinity Publisher) Profil erstellt mit (in English probably: Profile created with): Heidelberger Druckmaschinen AG (HDM ) (InDesign) and lcms (Affinity Publisher) The other fields were the same in both files. So I suspected this to be the reason for the different MD5 checksums. But not being an expert on the ins and outs of PDFs and colour management I turned to HilfDirSelbst.ch where we discussed this (in German) in this thread. Olaf Drümmer of callas concluded (my translation): So the question is Is Affinity Publisher correct in changing the meta-data of the profile when writing the PDF file? And if so: Would PDFX-ready need to append their list of MD5 checksums to include those of profiles created with lcms? Any insights and suggestions would be greatly appreciated! Best phph
Hi Affinity Team, I am having some issues with PNGs with transparency. If I add these PNGs inside a CMYK document and export them as PDF I get different colors behind the transparency of the PNG. This happens when I use the format PDF/X-1a:2003 or PDF/X-3:2003. If I use the PDF/X-4 the transparency problem does NOT occur. I am also having these issues with other pixel graphics as well, when I use blend modes like multiply. Please check the files attached to see what I mean. It would be great to fix this issue since most professional printer would like to have files with the PDF/X-3:2003 format. Thanks and Kind Regards Tim test.afdesign Test.pdf
Most of the PDF export options in the Affinity apps are pretty self explanatory but for the PDF/X… options? What advantages/features do they offer? And in what use cases may these be better export options to consider?
