Software developer Global Graphics introduced its new Harlequin Multi-Level Digital Screening Engine, designed for single-pass inkjet presses to achieve significantly better print quality.
The Harlequin Multi-Level Digital Screening Engine (HMDSE), explains Global Graphics, varies the amount of ink delivered from the inkjet head in any one location on any type of media to overcome common problems such as streaking and mottling that are frustrating many press manufacturers.
HMDSE is part of a new service Global Graphics will introduce to inkjet developers at drupa, that sees technicians measure test prints from single-pass greyscale presses, and process the results through Global Graphics’ new Digital Print Quality Optimizer tool. This calculates optimized patterning and overlaps for the various ink drop sizes available, to overcome common high-speed inkjet press problems such as streaking and mottling.
The Digital Print Quality Optimizer calculates the optimum drop sizes and screen pattern for particular combinations of press, greyscale/multi-level print heads, and substrate. The Digital Print Quality Optimizer allows the Harlequin Multi-Level Digital Screen to be fine-tuned for particular press/substrate combinations, with particular regard to controlling the overlap between different drop sizes as they are used to build up tones from light to dark.
