Safety papers
Safety papers have a background that makes alteration easily
visible. Scenic backgrounds or a repetitive pattern, such as a
logo, are some examples. Safety papers that consist only of a
patterned background are not foolproof.
Many financial documents are produced on a base paper, on
which a safety pattern is printed using stable inks. These inks do
not have the same sensitivity to chemical or mechanical erasure
as true safety inks. They are used because they look better and
are easier to print with. However, documents printed on these
papers are much easier to alter than those printed on true safety
paper.
Overprints
Overprints consist of a pattern or a scene that is printed over all
or parts of a printed document. Overprinting may be combined
with a texturing process. The varied colors and the texture make
it very difficult to modify the characters under the overprint
without affecting the overprint itself. However, overprinting adds
a step, which can make the check production process much
slower.
Textures
Textures can be printed on a form before the data is printed, or
applied with an overprint afterwards.
One type of preprinted texture is called “intaglio.” An intaglio
surface is created using a “male and female” die set. The
engraving is usually fine and the production cost of the final
documents can be high. Intaglio is a popular method used for
travelers' checks.
A problem with intaglio is that the surface is abrasive and can
cause problems for the reader sorter manufacturers. In addition,
attempts to place a dry ink image on a textured surface can
result in image deletions and distortions.
