Ink Recommendations
Ink used in preprinting should be non-volatile and oily. Ink suitable for pre-printing is
cured by:
Ultraviolet or heat (cured for 1 day)
Oxidative polymerization (cured for 7 days)
Ink cured by heat (Tinplate Ink)
Before using preprinted forms, make sure the ink is completely cured to prevent it from
transferring to the printer’s rollers and contaminating the internal printer mechanism.
The following inks are not suitable for preprinting:
Quick set ink
Ink dried by evaporation
Cold set ink
Ink dried by sedimentation or deposition
Ink dried by penetration
Paper Curl in Preprinted Paper
Preprinting can result in paper curl. Generally, the amount of paper curl depends on
which side of the paper is printed first. Refer to “Paper Curl” on page C-6 for more
information.
NOTE:
Preprinted paper should still meet the paper specifications after the
preprinting process is complete.
