Screens are Screaming for Attention

Maxtone is a hybrid screen that uses a high-lpi AM screen throughout roughly 80 percent of the main part of the tonal range. Below 10 percent and above 90 percent, very small dots are avoided by using FM techniques to vary the number of dots in these areas. "Maxtone allows the operator to set a minimum dot size in order to prevent the formation of dots that are too small for the flexo medium," says Agger. Creo applies imaging algorithms to smooth the transition between the AM and FM interfaces.
