Check Paper
Not all check paper is created equally. Some checks can
be altered without detection. However, if the check is written on safety
paper, it is harder to camp or wave.
One of the largest companies that manufacturers check paper is Tullis
Russell. It produces approximately 10,000 tons per year of check paper.
The company is based in the United Kingdom.
Tullis Russell uses various technologies for its check paper to help
prevent fraudulent check use. It treats the paper with different kinds
of chemicals that will make the paper show any major color changes.
Recently it developed a new security system that uses ultraviolet and
infrared visible fibers.
