What is a Rosette Pattern?

Brian Coale

If you've ever looked very closely at something printed on an commercial offset press, you may have noticed that the images and colors you see on paper are not what they seem. The reds are not really reds, and the blues not blues. Instead they are combinations of dots that, when seen adjacent to one another in tight groupings, give the appearance of solid colors and images. This process is known as halftoning, and it is an essential technique for all modern printing.
