First of all: English is not my main language, sorry for mistakes.
I am an absolute beginner in this whole topic, so unfortunately im having some problems with exporting a PDF document for printing. My project is a label for a bottle, I created my own design in affinity designer for iPad. The main font with the Name of the product has to be 100% black and set for "overprint". I followed all the steps that I could find online, I tried everything I could, but when I view the exported PDF in Acrobat Reader it tells me that the CMYK on the main Font is "C= 89%, M= 78%, Y= 62% and K= 97%". It should be 0/0/0/100%. Yes, I set a global color, set it to "Oveprinting" and turnt K to 100%, the rest to 0%. The Export format is PDF/X4. No matter what I do while exporting (embed profile yes/no, Font to curves, embed fonts etc., nothing changes). Can anybody help me with this issue? I'm at the end of my knowledge and just can't get this done. Pls help.
