UV-Set Newspaper Printing
Traditionally, newspapers have been produced with un-coated paper and printed with cold-set inks that dry by absorption into the substrate. The demand in recent years has changed to newspapers in combination with colourful supplementary sections and direct advertising printed on gloss-coated material. This type of work would normally require separate investment in a dedicated heat-set press and / or the installation of a large and expensive drying oven.
However, cold-set presses can be easily upgraded with a compact GEW UV curing system to enable production of high quality work on both coated and uncoated papers. Printing can be either UV or a combination of cold-set and UV. This enables the printing presses’ capacity to be expanded and more efficiently used in the newsprint area, allowing the glossy supplements to be printed during the day when the press would normally be standing idle.
GEW can offer this solution in both water- and air-cooled formats, and recently fitted a water-cooled system to a Harris M300 cold set press in Scandinavia. This enables the machine to run comfortably in excess of 30,000 impressions per hour when in UV-set mode.
