High Performance at High Temperatures

Beaming celebrities, brilliant colour photos, poolside landscapes with tropical ambience – lifestyle magazines, general interest publications, advertising inserts, and travel catalogues are mainly printed using the heatset offset printing process, a web offset technology that was developed for high-quality satin-finish or coated papers and that has limitless possibilities for the technical realisation of diverse formats and high circulation volumes.

The heatset offset process uses print inks that dry with brief heating. This special printing process comprises many individual process elements. The printed paper web is first run through a gas-heated drying oven, where temperatures soar to as much as 250°C. Chill rollers then regulate the temperature of the web down to a moderate 25 to 30°C, and a rehumidifying system allows the paper web to regain its earlier characteristics.

On-going efficiency increases, low tolerance of negative impacts are the hallmarks of heatset offset printing presses. System components that are designed to work together are becoming more and more important in ensuring high productivity and print quality.

tesa EasySplice® Heatset products make a considerable contribution to optimising the processes in all methods of splice preparation for flying splices. High performance heatset offset printing machines reach speeds of 80,000 to 100,000 copies per hour. A flying splice is necessary about every 20 minutes. The tesa EasySplice® product line offers state-of-the-art technology for fast, secure splicing in the heatset process.

The newest product development in the tesa EasySplice® line is tesa EasySplice® Heatset Black, with a black backing for optical splice recognition by laser. The main advantage of this approach is that it is no longer necessary to apply additional black detection labels.

tesa’s specially developed adhesive masses are also highly sophisticated, tolerating even more than the substantial temperature rise and fall that paper rolls undergo in the heatset offset process. Outstanding tack and easily removable liners are additional characteristics that have helped tesa make a name for itself throughout the world as a provider of first-class products.
