Over the past 20 years, the production of gravure cylinders has been considerably improved by using faster engraving machines, more precise engraving processes and fully automatic production lines. However, one process step has not yet been taken into account within all these optimizations and is still carried out manually: The proofing of the cylinder.

There is nothing new about the desire to optimize gravure cylinder engraving for more than just the process colors. When it comes to spot colors, the aim is usually to achieve higher speeds or save ink. Particularly in price-sensitive fields of application, this approach has been around a long time. Optimized cell geometries and inks…

In food packaging, metallized films or boards are used to provide a barrier to light, oxygen, water and odours. In gravure printing, Electrostatic Printing Assist Systems (ESA) are used to eliminate so-called “missing dots”, where the ink has not been transferred from the cell of the gravure cylinder to the substrate.

The HelioGreen Process is a three-pronged strategy developed by the Heliograph Holding group that offers a radically different way of producing the gravure forme and that therefore fundamentally changes the entire gravure printing process. Helio Pearl, a three-step process for the production of gravure cylinders, is a key part of this strategy. Flexo+Tief-Druck talked to…
