Final inspection of Dycril printing plates
Final inspection of Dycril printing plates under gold light at DuPont's new plant at Parlin, New Jersey. Operator here inspects plate to insure against surface flaws. When used in printing, the photosensitive plate is placed in contact with a negative of the image, dried and exposed to ultra violet light. A bath in a weak caustic solution washes out the unexposed portions of the plastic, leaving the printing surface. Time required from negative to start of the press-about 20 minutes. Dycril can be handled safely under gold fluorescent lights.
