Is it really possible to achieve blistering speeds with variable data and maintain optimum quality? How do you keep the presses running with no waiting time when every printed piece is different from the next? How do you mitigate artifacts like banding, or the inkjet smile, at the same time? Tom Mooney discusses a software engine that can drive data directly to the electronics whilst correcting for common quality defects at TheIJC.com. He draws upon two recent customer use cases.

Why is ScreenPro significant?
High-quality at ultra high-speed
Works on any inkjet press
With any workflow
With any ink or substrate
With any combination of printheads and electronics
The only solution to improve inkjet output quality that is
generally available to any inkjet press manufacturer

The Digital Series HD: a digital hybrid solution, combining the
advantages of digital workflows and digital printing, with the
capabilities of fast-change flexography technologies
ScreenPro Direct to electronics
First we tuned the Halftone Screens to get the quality up to the
Then we made it go fast, by tuning the software and hardware
It streams data and variable color images at high-speed and has
reduced process and RIP times on the Digital Series HD by as
much as 50%.
No limit to the number of VDP elements on one imposition meaning
every page is different.
Maximizes image print quality for high speed production inkjet
No loss in performance even with additional print bars to support
extended gamut colors
“The ScreenPro technology built in partnership with Global Graphics
is a key development to provide streaming full color VDP options to
meet the print speed requirements of today’s “next-generation” UV
Inkjet production presses. We were able to seamlessly integrate
high-speed streaming variable data into the existing ProWORX
digital front end”.
Ray Dickinson, Mark Andy, Vice President.
“For a workflow to be viable, it has to be able to process and send
full color, fully variable work at a rate that supports the press printing,
nearly continuously, at high speed to produce hundreds of thousands
of linear feet or meters weekly. This was previously a challenge with
the industry leading production speeds of Digital Series HD at 240

advertising with an approximate 70% share of the German bill
Ellerhold AG was experiencing quality issues on its large-format
posters, known in Germany as Mega-Lights, printed on its
MLM_2600_NG digital scanning printer
The printheads showed variation in printed density both between
the heads and across each head, which produced clearly visible
bands within some types of printed output.
How was the problem solved?
We sent our head of screening Dr Danny Hall to Ellerhold
as part of a Technical Services Breakthrough project
