Dot reproduction

The increased speed of the new generation of sheet-fed and web offset presses demands a new quality of printing blanket with optimal compressibility and good damping characteristics.

Aiming for the above mentioned goals PERFECT DOT® MR (Max.Rotation) was developed. In streak test diagrams a positive effect can be proved.

In addition PERFECT DOT® MR has been successfully applied to print on corrugated carton. Under these conditions PERFECT DOT® MR adapts superbly to the impression forces in the nip. Therefore it is possible to print on G- and F-flute while the favourable ink transfer allows a good printing result, regardless of the differences in the structure of the carton. PERFECT DOT® MR is therefore highly focussed on the special demands of such kind of stocks.

For the general application PERFECT DOT® MR is suitable for printing on paper and carton. Due to the good damping characteristics very good print results can be achieved on older web offset presses. It also shows a reduction in cylinder gap marks in this application.
