Mitsubishi opts for offline imaging for DI model

Mitsubishi Lithographic Presses (MLP) will show a prototype web press with variable cut-off and re-writeable cylinders at the Drupa show in May.

Unlike the MAN Roland DICOweb, which offers a similar concept, the sleeves will be de-imaged, coated and re-imaged off press.

We decided on an offline system because it delivers several benefits, said international marketing executive James Gann.

The press doesnt stop during imaging, makeready is reduced and capital expenditure is reduced as one Reusable Plate System (RPS) can supply multiple presses.

The Diamond MAX-V has a cut-off range of 546-625mm. Blanket and plate cylinder changes take two minutes, with ink and fount roller train and folder settings automatically adjusted. Its going to change everything forever, said Gann. At Drupa a single unit machine will be shown.

The prototype RPS to be shown at Drupa can produce a new plate in 14 minutes, although the firm expects the commercial version, which will go into test in the Japanese market within two years, to take three minutes.
