Primer

Finishing becomes more and more important in the printing industry. The right grounding makes a decisive contribution to the finishing results.

Primers are special coatings that take over the function of an adhesion promoter between substrate and a subsequent finishing.

For this purpose, different possibilities of finishing come into consideration in which specially matched primers are required and/or contribute significantly to the result improvement. Typical finishings are UV coating offline or inline on conventional inks. But also in case of film lamination or bronzing the employment of the right primer determines the result. There are also special primers for printing and coating in a second pass, if sufficient ink ducts are not available in one pass.

The primer guarantees a consistent surface tension. An absorption of the finishing material into the printing material is prevented to a large extent by the consistent surface. In addition, primers offer many advantages which enable trouble-free converting: minimization of blocking, minimization of the powder employment and no scratching.
