Global Graphics updates ScreenPro software

Global Graphics has announced version 2 of its ScreenPro screening software that is sold to printer vendors to help them smooth out imperfections in inkjet printing when developing new presses.

Tom Mooney, product manager for Global Graphics’ Advanced Inkjet Screens.

For this new version Global Graphics has developed PrintFlat technology which aims to mitigate the artifacts caused by variation within a head, or between heads or as a result of wear on the head itself. It works by addressing every nozzle separately on any combination of head and electronics, to achieve very fine granularity. It can be applied to any inkjet technology and vendors can use it to update existing machines.

Tom Mooney, ScreenPro product manager. “Print heads don’t have a uniform density distribution across the head resulting in visible banding. Different print heads will have different baseline densities and while these can be corrected by “tweaking” voltages this is time consuming and can affect the life of the heads.”

Mooney says that ScreenPro 2.0 also offers “significant performance improvements” to drive presses at full rated speed. There are also improvements to the print quality over banding issues such as chaining and mottling, that are difficult and expensive to correct mechanically.

ScreenPro is supplied to press vendors either as a cross-platform development component that can be implemented into a workflow solution or with a full branded user interface. Multiple ScreenPro engines can be run on the same server or offloaded onto separate computers for faster speeds, especially with dedicated ScreenPro engines sending print data at press speed directly to the drive electronics driving individual print bars for each colour.
