摘要： A full-color protected document, and methods and systems for making same, secured by a removable Scratch-Off Coating, where the protection against document alteration and/or copy type attacks is provided by digitally imaging Benday patterns and/or digital imaged background patterns around the variable indicia. By printing Benday patterns and/or imaged background using the same process color imagers, usability and integrity of the protected document are achieved relative to the consumer's perspective while at the same time providing a more secure, less expensive, and more aesthetically pleasing document design.
