Abstract
We started a study about Digital Halftone Screening Technology as new securities design. This technology is based on the PostScriptTM language. This technology arranged two kinds of images on the same plane equally and made it possible to get being perceivable or an invisible image. We named this technology “multi-image screen”. In this announcement, I report it about the anti-counterfeiting pinting products which is a low cost by process printing and introduce some trial products.
