SCREENING ALTERNATIVES -- Screen Out the Competition

Raise Your Tone Value

The major differences seen with stochastic screens were in tone value and print contrast, notes the report. Tone value, on average, was 10 percent higher compared to conventional 150- to 200-lpi screened work. This can be attributed to the fact that there are many more dots in a stochastic image, which introduces more area for tone value increase, the researchers explain.
