WASATCH PSS HALFTONING

SUPERIOR RESULTS IMPROVED

This improvement to Wasatch Precision Stochastic Screens (PSS) was introduced on February 3, 2006. If you're not already familiar with this feature of Wasatch SoftRIP, read more about PSS.

Improved Support for Fixed–Dot, Dilute Ink Printers

Wasatch PSS was a revolution in speed and image quality, and was particularly optimized for high–quality, variable–dot, printers. It has had some limitations when used with fixed–dot printers and dilute inks (light cyan and light magenta), particularly where strong ink reduction is required. This update corrects that limitation, making it possible to effectively apply very large ink reductions to this class of printers.

Caution!

Imaging configurations that are built to use this new feature will not work with any version of Wasatch SoftRIP dated prior to the February 3, 2006 build of Version 5.1.6. Dealers who build imaging configurations will need to update their customers to at least this revision date before those customers can benefit.

The new Fixed Dot Ink Reduction control changes the way that the Ink Reduction sliders are interpreted by the halftoning algorithm. It should be checked for fixed–dot devices only, because it will produce confusing results with variable–dot printers, such as those based on Epson print heads. It is specifically intended for fixed-dot devices that use dilute ink, such as light cyan and light magenta. It has no effect where light inks are not used. Checking this control for the intended type of printer makes it possible to use very large ink reductions.
