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?
