Printing Technologies Rotogravure/Flexographic



Heyne & Penke use the following printing technologies:


Rotogravure Printing Technology

For the rotogravure printing procedure, the information to be printed is mechanically applied to the copper of the rotogravure printing cylinder by means of electromechanical engraving or direct laser technique.

A picture mainly consists of four colours, the so-called 4-colour scale CMYK - cyan, magenta, yellow, key (black) with additional special colours (e.g. for logos) the so-called spot colours.

The circumference of the rotogravure printing cylinder refers to the packaging size to be reproduced resp. the cut-off length. This repeated pattern may exist once or several times on the circumference.

Heyne & Penke is able to print a maximum of ten colours in a printing width of 1300 mm. 

Due to the turn bar, also materials with five colours at the front side and four colours at the back side (the so-called reprint) can be printed. With these options, substrates can be laminated inline, then turned over and treated with cold seal at the reverse side.

The equipment of our rotogravure printing machines include - amongst others - up-to-date longitudinal- and cross registration regulation, video monitoring, and electro-static printing supports.

Together with experienced experts around our rotogravure printing machines, rotogravure printing results of highest quality are produced according to the released customer proofs.

Paper up to 120 g/m² can be printed and different types of foil (transparent, opaque, or metallised) from a thickness of between 10 – 70 my resp. compound foil and paper composites.


Flexographic Printing Technology

Flexographic printing technology is a high pressure printing process, whereby flexible printing plates are used.

The image information to be printed is set as a raised relief in a rubber- or photo polymer plate. These printing plates are mounted to a sleeve. The sleeve together with the mounted printing form is then positioned onto a so-called air cylinder. Lasered rubber or plastic sleeves are used for continuous designs as an alternative to individual plates.

An anilox roll (surface mainly made of ceramic) has small inserted lasered cups. Depending on their number (referring to one cm²) and their geometry, these transfer a certain colour volume to the cliché cylinder.

A doctor blade supplies the anilox roll with colour. The printing colour is located in the gap between two doctor blades.

We at Heyne & Penke use the new illustration technology Flexcel NX from Kodak which allows a significant improvement of quality and performance compared to usual digital technology.

This new system combines a high definition illustration with an optimized printing point structure and a DigiCap NX screening, which allows an enhanced efficiency of printing colour transmission.

Finest highlight details, seamless transitions in the design and each possible color graduation can be printed and because of the one-to-one image reproduction and flat-top dots, no detail is lost from the beginning to the end of a print run. A constant and consistent quality is achieved.

Our latest flexographic printing machine has eight colours- plus two imprint devices for lacquer- resp. reverse side printing. As the format cylinders are driven by a gearless servo transmission, any cut-off length in repeated patterns can be produced, equal to rotogravure printing.

Different qualities of paper and foil can be printed.
