Abstract
PURPOSE: To enhance the gradation reproducibility of a light portion without occurrence of moire by carrying out a process of printing a halftone positive or a continuous tone positive for lithography or letterpres on a photosensitive film and a process of printing a black line screen for photogravure on the film in an arbitrary order.
CONSTITUTION: Halftone positive 16 with base layer 17 downward is closely contacted to photosensitive layer 12 of photosensitive film 11 with diffusion sheet 15 in-between and exposed like the arrows to expose layer 12 with such quantity of light as shown by oblique line portion 14. As sheet 15 a milk white matted film or the like is used. Sheet 15 is then removed, and emulsion layer 24 of black line screen 19 is closely contacted to layer 12 and exposed like the arrows. Transparent portions 21 and opaque portions 22 expose layer 12 like corresponding portions 20, 23. After finishing the printing, film 11 is developed to manufacture the photoengraving screen having portion 25 with transparent lines and portion 26 with no transparent line corresponding to shadow portion a, middle tone portion b and light portion c of positive 16.
