I am working on publishing a book on Lulu. One warning it has about my PDF is:

Images: Your file contains images with line thickness less than 0.14 points. This may be too thin to print. Please review your file.

I have all of the EPS files that go into the book. However, I do not know how they were created, so I cannot edit the originals. Is there a way to edit the EPS directly to make all lines at least 0.14 points?

I see this question, but they had the original. I see this ps_thicken script, but it did not work for me.

  • Yes, you can redefine setlinewidth at start of the document so it cant go below 0.14 but its a bit out there kind of solution. Not for people with code allergy.

  • I don't have code allergy. How do I do this?

  • Just open the file in a text editir an redefine the setlinewidth command. The file is just a programming language snippet. Its pretty well documented online how to redefine builtin commands.

  • Thanks. I don't know postscript that well, and this is literally a Q&A site, so I'm hoping someone can answer with working code or a link to some working code.

  • Its not entirely within scope of graphic design .se if your into doing this manually in a graphic design application thats fine. But coding is outside of scope.
