Can I make pdf(version1.4) not to use distiller with FrameMaker2020 ?

Hi,

There are several options for you.

In Distiller change the PDF settings (e.g. High Quality Print). These settings set also the PDF version.

Or in the Publish pod select PDF and then click the small settings file icon at the bottom of the Publish pod to edit your STS file. Then deactivate Use Acrobat Distiller for PDF generation. Although there I can also select one of the PDF presets (e.g. High Quality Print) which sets the PDF version. I do not know, if you can edit this PDF preset, if you would not have Acrobat.

Best regards, Winfried
