Prit to PDF doesn't save custom size?
I am trying to create a PDF/X-1a that is exactly the size (dimensions) of the .xcf file (15x12in.). There are two ways to do this that I have found at this point. Export does save the correct size, but I can't find a way to change to the x-1a format, or print to PDF which does save the correct format but doesn't save the correct size. When printing to PDF I go into Preferences>Adobe PDF Settings and change the Default Settings to PDF/X-1a and change the Adobe PDF Page Size to 15x12 (custom created page size). When it prints the PDF ends up as an 8 1/2 X 11 file.
Two notes:
1. When I go to Page Setup in Gimp I cannot set a custom page size
2. The only reason I need the X-1a format is because when I export to a standard PDF the ink density for the black goes above the 240% limit that I need for the printers. If I could find a way to get the ink density results I need without saving in the X-1a format it would be just as good.
Thanks for the help!!
