The letters I.C.P. many people know the term but no one seems to know what it means.
Although they associate it with anti marking films as a generic term it is actually a trademark of Shinoda & Co.,Ltd . and the letters ICP were originally named as anti marking products that was the first item developed and released by Shinoda & Co.,ltd.
Today we use the ICP trademark for all our anti marking films and the ICP term now stands for Ink Contamination Prevention.
