Hi,

The command hasn't changed. The only diferrence I can notice is in the version of ghostscript. The smaller ones were generated via 9.07 and bigger ones with 9.53.
The text and image contents of the files remain the same. The only operation perfomed is to embed the fonts completely. Thats's were the size difference occurs. The PDF's were generated systematically. I can generate a sample file and provide it to you. I cannot share the currently generated files because it contains certain sensitive information.

For me it seems the only difference is in bigger fonts thats embedded into the PDF Files (9.07 had smaller font files comapred to 9.53.3).

My concern here ist how can I instruct ghostscript not to use the bigger Fonts or use the Resources from version 9.07?
