German company buys autoprint press

Dr Haas Mediengruppe, a German printing company, has invested in a highly automated printing system by MAN Roland, for printing the daily newspaper Mannheimer Morgen.

The Mannheimer Morgen is its flagship paper, with a circulation of 85,000 copies.

The MAN Roland Colorman autoprint press consists of four eight-cylinder towers, four reel splicers and two folders.

It prints with a maximum band width of 1,400mm and a speed of 45,000 cylinder rotations per hour.

For ease of use, the printing units of the Colorman autoprint are positioned lower than the units in previous models.

The units can be accessed via hoists, printing lifts or stairs.

The construction style does not lengthen the printing press, and eases maintenance.

In addition to automatic plate loading (APL) with a robot arm, the Colorman includes a fully automated workflow for the plate changing process.

With this system, the plate storage units can be loaded efficiently within the press, as well as outside the press in the central control console.

Via a rail transport system, they are moved into the loading position fully automatically.

This system reduces changeover time, and means print workers no longer have to be exposed to the noise and aerosols generated by the press.

The press also features a number of MAN Roland closed-loop systems developed to carry out quality-related adjustments directly and immediately on the press.

These include the automatic Inline Tension Control web tension control.

It keeps the web tension constant in the critical web lead area between the printing unit and the folder superstructure.

This reduces tension variations in individual paper rolls, between paper rolls, and in individual webs.

The cut-off register is optimised, the danger of web break is reduced and the creasing tendency minimised.

The press is equipped with the automatic Cutcon C cut-off register control, and the system operates almost entirely without additional marks.
