Normally, YUPO® does not
absorb ink. Accordingly, although it also depends on
printing press conditions, YUPO® has
approximately 10% more dot gain compared to coated sheets.
Note that SUPERYUPO® FRB, FRR, and ULTRAYUPO® FEB are grades with improved dot gain.
|
- Be sure there is no excessive build up
of ink. This worsens dot gain.
- Be sure to carry out color proofing using
the actual sheets and printing press.
- Dot gain can be corrected by approximately
10% at the film stage or, in the case of
positive plates, the exposure time can be
increased when making the plates.
- For CTP systems, be sure to make corrections
using a tone curve during prepress.
