Description
Radical curing, solvent free, stable one-component UV silver ink for
paper, board and different non-absorbent substrates based on leafing
aluminium pigments with excellent lithographic properties.
Application:
UV offset printing on paper and board, for example, folding cartons.
The selection of the substrate has an enormous impact on the final
result of UNIPAK SUPERCURE UV silver inks. This is true not only for
optical properties brilliance and hiding power, but also for printing
properties such as adhesion and transfer.
Very absorbent or uneven substrates often cause a bad pigment orientation
resulting in inferior brilliance. Additionally these substrates can
negatively influence transfer properties, adhesion and curing by absorbing
essential parts of the binder.
In some cases it might be advantageous to print a suitable primer
first, in order to improve surface properties of the substrate.
Product properties:
Rub resistance:
The UNIPAK SUPERCURE UV silver inks are based on leafing aluminum
pigments leading to low to middle rub resistance properties even if the
ink film is fully cured. For better protection an UV lacquer could be
applied, however a decrease in brilliance will result.
*Must be purchased by case of four 5.5lb cans
