for me, black must be black. white must be white. or at least they must be close to it.

it's damn annoying when you do a nice design and people start complaining it's dark la this la that la but when you visit their machine you found out that on their monitor, white is almost halfway to black. sheeesh, no wonder dark blue and white words look damn dark to you %(&$#*%( user.

LOL.

monitor - RGB
printer - CMYK
some industrial printers - they actually manually mix colors to get the exact color you want.

print output also varies from printer to printer (ie Epson vs Lexmark vs Canon vs HP) and also varies from paper to paper.

so even if your printer outputs same like your monitor, the print service provider may still output it a bit differently.

i donno about you guys, but my Samsung 151s is nice. red is red. it looks just as good / bright as CRT.

on the other hand my CRTs (previously) always have brightness/ contrast to the high side, some times even max.

i like to see my whites as whites, black as blacks.
