Flat-bed die cutter

Processing of corrugated cardboard with a flat cutting die (in contrast to the rotation process).

Flat die-cut cutter

Corrugated cardboard sheets are locked in the flat-die cutter and punched out by a flat-bed die-cutter in one stroke movement. This results in very precise die-cuts.
The difference to a rotary die cutter are the die-cut movements and the customised Tools.

Flexo-HQPP (HighQualityPostPrint)

Flexo direct printing at the highest quality level with cost-effective production for smaller print runs.

Flexo printing

Flexo printing is a direct high-pressure process which uses flexible photopolymer or rubber printing plates and low-viscosity inks. As a high-pressure process the raised areas are the print form and image-bearing.

Flexo Postprint

In contrast to Preprint, in corrugated cardboard direct printing, the printing is performed on the outer liner of the corrugated cardboard. This is suitable for simple printed images where high quality is not a requirement.

Multi-wall packaging

This consists of two or more layers of fluted paper (wall) which are glued together by a layer of paper or cardboard (intermediate liner) and where its free external surface is also glued with a layer of paper or card (external and internal liner).


Offset Print

Offset print is an indirect flat printing process whereby print and non-print areas lie adjacent to each other on one level. Printing and non-print areas are separated by the physical principle of fat- water repulsion. High-viscosity printing inks are used which are transferred by the print form cylinder and the blanket cylinder onto the printing Substrate.
In offset printing (up to 100 lines/cm) more lines/cm can be printed on the printing substrate than in flexo printing (18 to 54 lines/cm). The higher the number of lines, the clearer the image when viewed closely. Typical applications for offset printing are gift boxes, brochures, posters and Displays.

Score lines

The score line prepares mobile or hinged bending points designed to specify the geometric location of the bend, the creation of a hinged, bendable geometric cross-section and reduction of bending resistance at the bending point.

Screen printing

Screen printing is a direct printing process in which printing ink is printed with a rubber squeegee through a finely-woven fabric on the material to be printed. On those positions on the fabric where, according to the print image, no ink should be printed, the mesh openings of the fabric are made impermeable by a stencil.
Classic screen printing has been largely replaced by digital printing.

Secondary packaging

Wrap-around packaging is packaging which is assembled, filled and closed using automated machines. The particular feature of this automated packaging is that the three work steps described can be performed within one cycle, in other words, only one machine is required to manage them.
In practice the die-cut of the wrap-around packaging is shaped into a "U" into which the products are positioned laterally. The packaging is then closed with hot glue. The counter-pressure which occurs when it is filled with the products ensures it is glued securely.
