For the needs of experiment three types of digitalized
printing forms were constructed whose coverage ranged
from 0 to 100 % screen value in a step of 33 % of screen
value. For experimental printing the UV InkJet printer
Cutter Roland Versa LEC 300 was used which apart from
the standard CMYK uses UV varnish and UV white ink. In
Versa Work RIP the following parameters were defined:
varnishing mode (gloss), resolution (740 × 740 dpi), head
moving (un-indirection) and screening method (dither).
Three standard printing substrates were used in the
experiment: offset paper (Masterprint 140 g/m ) mat
calendered paper (Splendogel EW 115 g/m ), fine art paper
(Chorus lux gloss 130 g/m ).
