Suede varnish and metallic varnish

First, suede varnish and metallic varnish

For the characteristics of modern printing, environmental protection and anti-counterfeit effectiveness, based on the water-based gloss oil and added a number of special effects of water-based Varnish, which has a high use value is the water-based suede Varnish and Varnish.

The water-based suede varnish is an effect that the aqueous varnish system exhibits suede during the drying process after coating.

Second, alcohol-free (ipa) fountain solution

In order to reduce the amount of alcohol used in printing and improve printing quality, the use of alcohol-free fountain solution has become a trend. In response to this situation, a new alcohol-free fountain solution from Varn has solved this problem.

(1) Addition amount of fountain solution: 3-5%;

(2) The amount of isopropanol added: 0-6%; depending on the amount of fountain solution added and the way the printer feeds the water, it is not necessary to continuously add during the production process;

(3) In the use of alcohol-free fountain solution, it should be noted that due to the compatibility and operational habits of the Sheung Shui system with the fountain solution, it is recommended that alcohol be reduced first, and after a certain period of time, alcohol-free operation should be performed again.

When using alcohol-free fountain solution, note that the original water distribution roller of the printing machine contains hydrophilic substances and is a water roller that can directly use an alcohol-free fountain solution. However, if the non-original water roller is replaced, no hydrophilic substance is contained, it will affect Use alcohol-free fountain solution.
