[scribus] Fonts in PDF for Blurb

[Bert Driehuis]

Hi Šarūna,

I am not a preprint expert either, but if I understand the printer's story
correctly, part of the problem was in using layers (and thus,
transparency). Many printers have problems with transparency, so I usually
limit the PDF version to 1.3 when dealing with such issues. Selecting 1.3
forces Scribus to remove the problematic features from the PDF.

The problem with embedding fonts is that a font is, in essence, a program
to render letterforms. And that program can have bugs. Most fonts have
small errors, and sometimes a printer's software will trip over errors that
your own software doesn't have a problem with. By outlining the font you
include the letter forms by generating them on your own computer. This
eliminates any differences in interpretation.

I learned this the hard way. In my case, the printed result had black
splotches where I had accidentally used an image with transparency. I have
to this date not found a free tool that will point out such problems.

If you're interested in checking the quality of a font, you could try
opening it in FontForge and running its verifier. You may be surprised by
how many errors lurk in some expensive commercial fonts...

With kind  regards,

Bert
