What are the advantages of waterless offset compared to wet offset?
Higher printing quality
Less dot gain
Through the high water share during the wet-offset printing process, the ink is easily absorbed by the paper. The capilar floating effect of the paper enlarges the dot size and reproduces an unprecise dot shape. Even on plastic surfaces there is a higher dot gain in wet offset through the emulsion of water and ink.
Higher colour saturation / higher colour density
Sharp reproduction of image by better registration accuracy
Improved colour consistency
Reduced production costs / Higher production output
Reduced waste of sheets / cards by setting up the offset press
Shorter make-ready time of the press
Easier adjustment of colour density without water-ink balance control
No dampening solvent necessary
Less cleaning time of ink fountain and rollers by using UV-inks
No need of rubber protection fluid for offset plates after printing
No use of hazardous alcohol and aciditive dampening solvent
Saver working environment
Less paper / plastic waste
Better printing results on recycled paper
Is it possible to laminate sheets printed in UV waterless offset?
Laminating on top of waterless inks is possible and frequently done in the printing industry. Nevertheless, it is necessary to consider that inks have to be approved before. Inks, offered by MICTOM have passed lamination tests successfully ( …see our product list ) but the lamination results depend on several parameters except the ink.
Therefore we recommend to test the inks with regard to lamination quality.
It is fact that, the higher the silicone share is in the ink, the more difficult the lamination process will be.
Another possibility is to print a transparent adhesion agent on top of the colours prior to lamination.
