Hi I am not able to create PDF/A document, that could pass the online validator
http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
I tried many combinations of the colors depth, color types (RGB, CMYK etc.) and other parameters.
The most succesfull attempts was with the one with only ONE error:
"The value of the key N is 4 but must be 3."
Has anyone had success with this kind of PDF format??
