Operation cautions

1) This product can be applied for varnishing in on-line printing machine, off-line varnishing machine, spot varnishing machine and other several kinds of methods.

2) It can be used directly without adding solvent. For off-line roller application, if the viscosity is too high and paper stick on the roller, it can be helpful to heat the product to 45-50℃ or dilute it by ≤10% toluene.

3) It can be applied directly without primer and have excellent adhesion, gloss, crack resistance and other characteristics.

4) Coating amount suggested to be 3～5g/m². Real coating amount is depending and to be adjusted on the printing paper and ink thickness.

5) Special inks (ex. reflex blue, pink and so on) are easier to cause smudge and poor high temperature resistance and make the prints apt to be discolored. It needs special attention in the proofing test.

6) The dark part of the Stack four-color and gold / silver ink are easier to make the adhesion weak. It needs special in the proofing test.

7) The above data is provided by our laboratory and for operation reference purposes only. There might be some difference due to actual substrates and UV coating ways. Before applying large quantity, the proofing test of product adaption is required according to the special requirements
