This is a standard formula recommended for development of Reprolith and Reprolith Ortho Films. This one-solution formula is recommended for greater convenience. For better keeping quality the two-solution formula is preferred.
Use solution full strength. Normal Development time: 1 to 3 minutes-at 20ºC.
