Have you ever looked at a magazine picture through a strong
magnifying glass? You will find that it is made up of dots. Here are
two pictures of a baby —one as if it were a photographic
print, and the other as if it were a magazine photo, blown up 200, 400, and 800
times. (The focus is on the baby's nose.) A magazine printing press usually can only print four colors:
Cyan, Magenta, Yellow, and Black. Our eyes and brain put colors
together from the colored dots. Printers (and the computers they use to help them) print the dots in
special grids that do not overlap. On the next page, you will try to
match a "magazine" color by building it from dots. Go! |
