Hey there,
I am attempting to prepare artwork for print. I have sent four different designs to a print service and I have followed their recommendations to use CYMK format with FOGRA39 profile because this is industry standard for printing press. My original designs were created using standard RGB. I then created the PDF template files that have CYMK format with FOGRA39 profile set and dropped in my designs. I edited colour settings to fix any discrepancies as best I can and exported as PDF to send to the print service. However when the print service 'export' my uploaded PDFs to make them 'print ready' for their print workflow (CYMK format etc) , these PDFs are available to me in my account and they have increased colour de-saturation. The print service has also advised that two of my PDFs are in RBG format and this explains the colour de-saturation for the two most colourful illustrations. But I have definitely exported the original PDFs using CYMK format and FOGRA39 profile.
In an effort to troubleshoot this, I have downloaded the converted 'print ready' PDFs. When I view/open the PDFs in my MacOS Preview application, I can see the colour desaturation. See attached PNG file 'PDF-viewed-in-iPad-viewer'. However when I open using Affinity Photo the colour saturation, brightness and contrast are what I want. Please see attached PNG 'PDF-opened-in-Affinity-photo'. I have attempted to search for an answer on the WWW but I am bamboozeled. So I am aiming to have my images as close to print ready using CYMK. However Affinity appears to be not showing accurate CYMK colours so I can 'proof' my artwork for the printers. And possibly not exporting in the selected CYMK format and selected profile.
MacOS 12.3.1 running Affinity Photo Version 1.10.5
I see the same behaviour on iPad Pro 12.9 2021 with Software version 15.4.1 running Affinity Photo Version 1.10.5.280
It is very possible I am missing something or doing something incorrectly so I am here to learn and get things right.
Thanks in advance!
