Trelleborg offset blanket stops ink trapping

A Trelleborg Printing Blankets product story

Swedish printer Ekotryck Redners has purchased Vulcan Image 4U blankets from Trelleborg to stop black ink trapping to the yellow cylinder.

'We operate a range of multi-colour Heidelberg presses, but the problem was most apparent on our seven-colour Speedmaster XL, which is equipped with cold foiling, as well as water and UV varnish facilities,' said Roger Malmgren, Ekotryck Rdeners' production manager.

'Hostmann-Steinberg recommended Trelleborg's Vulcan Image 4U blankets, which we tested on the seven-colour press,' he said.

'The issue of trapping disappeared immediately and there was also a significant improvement in print quality, with much cleaner images,' he went on.

'We quickly changed to Vulcan throughout the factory and no longer have trapping problems on any of our presses, while the press operators report that the greater durability offered by Vulcan means they change blankets less frequently,' he added.

The Vulcan Image 4U is a compressible offset blanket.

The smooth micro-buffed surface is claimed to provide very low dot gain, while the quick rebound carcass ensures high mechanical resistance.
