Gröning Drucktechnik – Quality in Press Service

Services

Installation & dismantling of printing presses

We dismantle printing presses professionally to manufacturer specifications, document every step, and pack and preserve everything properly for transport or storage.

At the new site we reassemble the press to manufacturer specifications and align it with the highest precision. From planning through installation to commissioning and the first test print, we support you all the way, from a single source. Heidelberg, Koenig & Bauer or manroland, worldwide.

Repair & maintenance

When a press stops, every hour counts. We respond quickly and flexibly, talk the problem through by phone first and are soon on site.

We handle repairs of all kinds, from cylinder exchange and bearing replacement to suction heads, with or without spare parts. A regular maintenance programme keeps your press running reliably and makes unplanned downtime less likely.

Ultrasonic cleaning for anilox rolls & machine parts

Our special process combines dedicated cleaning agents with ultrasound. Dried primer, coating and ink residue is removed gently and thoroughly from the cells of anilox rolls – they come out clean and free of residue.

Clean cells transfer ink and coating evenly again. The method also works for other machine parts with stubborn deposits.

Used press check

Anyone buying a used press wants to know exactly what they're getting, because nothing is worse than buying a pig in a poke. We inspect the press to the scope agreed with you. That includes a test print, cylinder measurement, a stress test and a check of every unit.

We pay particular attention to the mechanics, because a good press stands or falls with them, and of course we check for cylinder damage. Our long experience uncovers hidden defects and costly surprises before they become expensive. You receive a clear report on every unit, with measurements, photos and videos, as a reliable basis for your decision.

CO₂ dry ice cleaning for printing presses

Dry ice blasting cleans gently, dry and without solvents. Nothing is abraded and no water remains. We clean the inking, dampening and printing units, as well as gripper bars, tong grippers, the perfecting unit and sheet guide plates.

On request we replace the rollers at the same time. From initial advice through preparation and cleaning to roller installation and recommissioning, we take care of everything from a single source: straightforward, fast and flexible.

New impression cylinder jacket fitted, with the grippers in front

Ink-repellent impression cylinder jacket from LMC

Impression cylinder jackets

Ink-repellent impression cylinder jackets from LMC for Heidelberg Speedmaster presses – fitted by us with exact measuring.

Steel jackets with a ceramic base coat and a metal coating: ink hardly settles, nothing sets off onto the following sheets – for a clean reverse side.
Resistant to solvents and heat, easy to clean by hand or with the automatic wash-up.
Exact fitting is decisive: we measure the cylinder packing before and after, so that the jackets lie one hundred percent flat and no doubling is built in.
Transfer jackets and further sizes on request – tell us your press type.
