I'm using the latest version of Ghostscript "GPL Ghostscript 9.50 (2019-10-15)" but still I'm unable to convert PDF to PDF/A. The command which I used for conversion gs -dPDFA -dBATCH -dNOPAUSE -sProcessColorModel=DeviceCMYK -sDEVICE=pdfwrite -dPDFACompatibilityPolicy=1 -sOutputFile=output_filename.pdf input_filename.pdf it is saying that GPL Ghostscript 9.50: Annotation set to non-printing, not permitted in PDF/A, reverting to normal PDF output. Is there any problem with my command, if there so please let me know with a proper solution.
Thanks & Regards.
