Wirbelwind 8161
Anti-set-off powder on starch basis for paper and board.
Function:
Wirbelwind supports the following sheet, until the surface drying
process has started. Once the Powder has served it's purpose, it is
absorbed by the ink film without reduction of gloss and without
affecting the properties of the printing ink film. The surface is
perfectly smooth. Where mineral powders are used, as it is frequently
the case, a portion of the grains remains outside the ink film; the
consequence: rough surfaces and the so called sandpaper effect. This
can cause difficulties in further processing. Wirbelwind has
none of these disadvantages.
Advantages:
Minimum powder application= more efficient working Smooth printed
surface= No sandpaper effect. No problems during finishing (coating,
calandering etc.)
Not detrimental to health!
Areas of use: In all powder spraying devices in letterpress
and offset printing. For paper and board. |
