HelioBrush from Daetwyler Graphics

Since the launch in 2016, a number of Daetwyler Finishstar P1610 Cu units have been equipped with HelioBrush. Cylinder manufacturers and printers are equally enthusiastic about the resulting copper surface finish. In addition to shorter process times, they also appreciate the improved print result.

Previously, HelioBrush was primarily used instead of the second stone head in the Finishstar P 1610 Cu. This was because it was originally believed to achieve a predictable, controlled, and stable result, albeit at the expense of process time. However, the results of comparative testing using the thin-layer process show that cylinders can be ground ready for engraving up to 50% faster than in applications without HelioBrush – especially in the higher surface roughness range of Rz = 0.40-0.60. This means there is nothing to stop HelioBrush being used on the CFM P 1610 Plus (the band polishing head is replaced on this type of machine). The far more homogeneous surface structure produced by the proximity of the Rz and Rmax values also influences the roughness after chrome plating. This remains constant and therefore reduces the risk of scumming in the print.

The brush’s longer service life than stone and the halving of stone sludge are thus no longer the only plus points for cylinder manufacturers. Much shorter process times are a further advantage. The benefits for printers are clear and are reflected in their call for a HelioBrush process. The HelioBrush module can either be selected when purchasing a new machine or retrofitted on machines built in or after 2009.
