Preprinted forms considerations

Inks

Generic MICR Fundamentals Guide
The combination of consistent data format and element location
makes preprinted forms useful in MICR applications. Additional
requirements for security features, either in the base paper stock
or in the preprinted form, come from the need to protect a
financially negotiable document.
You need to consider several factors related to ink and paper
when selecting a preprinted form for any type of laser printer.
Preprinted check stock must not offset (transfer from a printed
sheet onto other surfaces). Work closely with the forms vendor to
ensure that requirements are understood and met. Always test
the application on the appropriate printer before production
printing.
Choosing the correct ink is the first step in designing forms that
function well in Xerox printers. Inks for these forms must cure
well, must not be tacky, and must not offset. In choosing an ink,
you must consider the amount of heat and pressure to which the
forms will be exposed while passing through the printer. You
must also consider the dwell time–the amount of time that the
preprinted paper is subjected to those conditions.
Good performance has been reported with the following ink
types:
• Oxidative inks: The following qualities are desirable in
oxidative inks:
– Non-volatile, cross-linkable vehicles
– Internal and surface-curing driers
– Minimal use of antioxidants
– No slip agents
– pH in the press fountain high enough to permit curing
NOTE: Oxidative inks can require several days to harden
satisfactorily.
• UV cured inks: Inks that are cured using UV (ultraviolet) light
change immediately from liquid to solid upon exposure to an
intense UV light source.
