WRN; ground breaking in two front.

Did you know that US postage stamps used to be printed not by the offset but by gravure and other printing methods?         This all changed around 1980 when change over to offset finally reached the government printing office.       Till then offset plates runs were only to a medium run length and not to the required long length run.          Our WRN was designed to combine tested and proven diazo system and a long running photopolymer system.       This 50 states bird stamps were the first demonstration of WRN to be used for the postage stamp application.        In this sense WRN plates were ground breaking for the industry as well as for Polychrome.      We continued advancing diazo and photopolymer hybrid technology as our core technology and the WRN was the first in this regard.
