Paper facts
3-14 Generic MICR Fundamentals Guide
• Laser inks: Inks that are formulated specifically for use on
forms that will pass through laser printers are a recent
development that holds considerable promise. These inks
cure promptly (usually within 24 hours) and are formulated
with laser printer conditions as a design criterion. They can
be expected to reduce offsetting and other problems
encountered with other types of inks.
Laser inks may be oxidative, UV, or heat set types.
Another option is to use Xerox forms, whose performance is
guaranteed. The same guarantee should be expected of the
forms vendor chosen by the customer.
Security features
Checks and other negotiable require protection against
fraudulent use. Security features can be incorporated into the
base stock when the paper is made, or they can be part of the
preprinted form. These features should be chosen to achieve
sufficient document security without negative effects on printer
operation.
A secure document is protected against both duplication and
alteration. Security features should be selected to address each
of these aspects effectively when they are used in a MICR laser
printing system.
A detailed discussion of check security is contained in chapter 8,
“Security.”
Duplication detection
The most common security features for detecting duplication of
forms include:
• Microprint: Extremely small type used to print a message or
phrase that is readable under magnification
• VOID pantograph: A pattern of varying halftone screen
frequencies in the check background that causes the word
VOID to appear in the background of a copied check
• Split fountain backgrounds: Continuous fade from one
color to another across the document
• Microfibers: Tiny colored or UV treated fibers that are
incorporated into the base paper stock and are easily visible
under normal or UV illumination.
