Selection and application of plate mounting tape in label printing

Introduction of paste version of foam tape:

A good foam tape can not only play the role of fixing plate, but also enhance the quality of printing. For example, as Desa softprint series, the typical foam tape comprises glue, sponge, stable film and a release paper. Coated glue in both sides of the tape, which are respectively pasted on the plate and the plate roller, can play the role of fixing plate. Foam is the important part of plate mounting tape, which can be achieved on the printing pressure fine control through the foam density, to improve the printing effect. There are three aspects to affect foam characteristic: the cell structure of foam, foam compression recovery and foam hardness. Compared With irregular cell, all round and the mean distribution bubble holes, can provide high quality and stable solid and dot printing effect.

The good foam compression recovery rate can ensure stable printing quality and extend the life of tape. The foam density determines its soft hardness. Different foam hardness can produce different mesh point and field effect of printing, which is the important factor of the choice of adhesive tape. Stable film in the tape can prevent the plate positioning on the foam tensile, in addition, it can provide a uniform stress zone in the printing process. The effect of release paper is to prevent the tape stick each other, the release paper with a convex surface can also help to remove the plate in the process of bubble.

Paste version of foam tape selection

How to select a suitable adhesive tape affixed version? It can consider from the following respects:

1. For the foam tape, thickness is generally refers to the thickness of press printing, when no compression, the thickness is generally slightly thicker. Plate mounting tape thickness will affect printing repetitive perimeter, in addition, to some extent, it will affect printing quality. In generally speaking, the thicker the tape, printing effect can be adjusted the bigger space.

But the flexographic printing machine has its inherent tape thickness requirements, to label flexo printing, 0.38mm thick plate mounting tape is the mainly. What need points out is, calculation of flexographic printing gap need to calculated plate mounting tape thickness.

2. Printed pattern is usually divided into dot and field, it mainly through the choice of different hardness of plate mounting tape to achieve different printing effect. for the tape, super soft tape can be reached most fine dot printing, or compensate the printing effect (ink) of the gear runout; soft belt meet the fine dot printing; neutral tape meet comprehensive printing; hard tape meet good field effect.

3. The current label printing development trend is the variety, runs a small, cycle is short, so the tape quality stability and easy operation becomes more and more important, in the choice of adhesive tape, better product quality and good operation performance is also necessary to consider.

Flexo is a kind of fine printing process, there is many variables to control. With the manufacturers require more and more high quality to label printing, each of the process control of printing process becomes more and more important.
