PROP, the only packaging-specific specification, was originally intended to represent ideal conditions for printing on carton substrates including solid bleached sulfate, recycled board, and polycoated boards. Unfortunately, the PROP committee has disbanded and development on this spec is discontinued. Flexography's F.I.R.S.T. represents the most active specification initiative targeted directly at packaging applications and substrates (see packagePRINTING, January 2000).
