Dear Affinity Users and Developers We’re just in the process of evaluating Affinity Publisher (tested with 184.108.40.2065 and 220.127.116.112) 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
PNG Files with transparency inside a CMYK creates different colored backgrounds on export for some PDF/X formats
Inspirimental posted a topic in Bugs on MacHi 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?
