Hi Kamil,

The dot edge definition of H-UV inks, particularly of the black ink, is not good as the oil-based conventional inks. The uncorrected TVIs (from linear plates) are typically higher than the uncorrected TVIs of oil-based inks. The black channel displays a certain noise (and even a higher TVI) in the highlight to quarter tone range. You may think of creating/using an ICC profile in which black starts at a higher percentage. You should be using GCR sparingly.

Good luck.

Subject: [ECI-EN] Stochastic screening HUV

Dear colleagues,

has anybody of you experience with stochastic screening (preferably Staccato) and HUV ink? What about TVI - it is uncorrected TVI comparable to uncorrected TVI at conventional print process?

Thanks for any insight!

Best regards,
