[Tex/LaTex] Recommended resolution (dpi) for \includeimage pics (pdflatex)


I designed a newsletter using a logo and a topbanner, 2 pages.
It is to be send by mail (A4-paper) and by e-mail (pdf).
As usual, I used 300dpi for my graphics.

The result is 1.2M in size, which is on the limit for some recipients.
Is 300dpi too much? Is there a certein resolution pdflatex uses to
scale an image to let's say 5cm? Any experiences, what resolution is
good for both, on screen reading and printout? (Home laserprinter)

Take the size of your monitor in inches and your current resolution, perhaps 1600x1200 on a 21" monitor? That’s roughly 127 dpi horizontally. 1024x786 on 19" is roughly 90dpi. So if you supply more “dots” per inch they have to be reduced by the programming used for displaying the pdf.

For printing however this is not enough. It gets even more complicated when colors are involved.

However with pdfs you don't have to use raster graphics. If the logo is available in a vector format it might be considerable smaller and still look good on screen and print as well.
