How does texexec --pdf file.tex includes the images into the target
pdf file?
Does texexec process modify the images?
What is the target resolution of the pdf?
- texexec, i.e. pdftex, just embeds images (also pdf) without
changing them, besides scaling
- a PDF has no resolution, only some embedded contents may have any
How should I optimize the process for digital or offset printing?
- define your colors in cmyk (at least *also*)
- prepare your pictures for the right resolution; if you need two
versions (say web and print) you'd need to prepare both; you should
name highres and lowres the same, only put them in different
directories, so you could use mode sections that define the image path.
- the right resolution depends from the printing method and the
screening.
a common rule of thumb for color and greyscale pictures is "twice the
screen" (res. in dpi, screen in lpi), but \sqrt{2} would in fact be
enough.
line art pictures should have the resolution of the printing device,
but 800 dpi is mostly enough.
- if some elements should touch the paper border, they must "bleed"
2-3 mm over to avoid white "flashers" after cutting; that contains
that the printing paper sheet is bigger than your final paper size.
- you can prepare book(let) ordering of your pages with ConTeXt;
that's called "imposition" in prepress and "arranging" in ConTeXt.
What else do you need to know?
Perhaps you're interested in my formula collection for printing
