Protecting Checks from Alteration

There are several ways to protect your official checks from fraudulent alteration because there are several kinds of alteration that can occur. Mechanical alteration is the removal of a printed character by scraping the ink or toner with a knife. To help prevent this from occurring you need to verify that the MICR toner and paper you use to print official checks work in unison and provide superior adhesion. The highest level of protection against mechanical alteration is the use of "indelible" printing, a process where the printed characters permeate through the document preventing removal of the entire character without destroying the check.
