SCREENING ALTERNATIVES -- Screen Out the Competition

To help printers gauge the merits of alternative systems, the Graphic Arts Technical Foundation (GATF) has conducted several independent tests. The basics are covered in the "Stochastic and Hybrid Screening Printability Study" report that GATF released in 2003.

According to the researchers, this study was designed to show the differences between currently available conventional and stochastic/hybrid screens, particularly the products from the seven suppliers that participated in the study. Measurements were collected for density, tone value increase, print contrast and gray balance, then the data were compared to show the differences between conventional and stochastic/hybrid screening solutions.
