Abstract

Использование: в фототехнике. Сущность изобретени : при фотопечати контроль за процессом осуществл етс  путем освещени  фотоматериала светом спектрального состава, нечувствительного к фотоматериалу, причем освещение осуществл етс  одновременно двум  источниками света взаимно дополнительных цветов . Кроме того, фотоматериал в данном способе освещают зеленым и красным светом. 1 з.п. ф-лы.Usage: in photographic equipment. SUMMARY OF THE INVENTION: in photo printing, the process is monitored by illuminating the photographic material with spectral-insensitive light, which is insensitive to the photographic material, moreover, the lighting is carried out simultaneously by two light sources of mutually complementary colors. In addition, the photographic material in this method is illuminated with green and red light. 1 s.p. f-ly.

Description

Изобретение относитс  к черно-белой и цветной фотографии, а конкретнее к процессу изготовлени  фотоотпечатков.The invention relates to black-and-white and color photography, and more particularly, to a process for making photographic prints.

Целью изобретени   вл етс  повышение качества контрол  за процессом фотопечати .The aim of the invention is to improve the quality of control over the photo printing process.

Поставленна  цель достигаетс  тем, что в способе фотопечати, при котором контроль за процессом осуществл етс  путем визуального наблюдени  при освещении фотоматериала светом спектрального состава, к которому фотоматериал нечувствителен, освещение осуществл етс  одновременно двум  источниками света взаимно дополнительных цветов. Кроме того, фотоматериал освещают зеленым и красным светом.The object is achieved in that in the photo printing method, in which the process is controlled by visual observation when the photographic material is illuminated with spectral light to which the photographic material is insensitive, the illumination is carried out simultaneously by two light sources of mutually complementary colors. In addition, the photographic material is illuminated in green and red.

Взаимно дополнительные цвета воспринимаютс  глазом человека в сумме какMutually complementary colors are perceived by the human eye in total as

белый цвет. Это освещение не создает искажений в процессе визуального контрол  за фотопечатью и обработкой фотоматериала.White color. This lighting does not create distortions in the process of visual control of photo printing and processing of photo material.
