Illustrator - export to PDF warning
I have created a Custom Preset to output an Illustrator file for print based on the PDF X4 2008 already created by Adobe. When I try to use this Preset I get a warning as follows-
The preset specifies Acrobat 5 (PDF 1.4) compatibility.
This will be reset to Acrobat 4 (PDF 1.3) to ensure compliance
with the PDF/X (2003) standard with regard to transparency.
Despite the fact the preset uses PDF 1.6 this message appears and no amount of adjusting the settings seems to change it. If I use the same Preset in Indesign there are no warnings.
Using the Adobe Preset for PDF 1.6 (in Illustrator) seems OK, so not sure why when resaved with only a couple of modifications (bleed and compression) it gives this warning.
