摘要:
A full-color protected document, printing method, and system secured by removable Scratch-Off Coatings where the protection against microscratch type attacks is provided by ensuring strategic placement of similarly colored and/or patterned variable indicia. By printing the variable indicia with similarly standards, usability and integrity of the printed indicia are achieved relative to the consumer's perspective while at the same time providing countermeasures to illicit microscratching attacks.
