Description

Известны способы дл  цветоисправленной печати цветных изображений на многослойных позитивных пленках с цветных негативов, с применением маски дл  подсвечивани  печатаемого позитива,  вл ющейс  позитивным изображением негатива.Methods are known for color-corrected printing of color images on multilayer positive films from color negatives, using a mask to highlight the printed positive, which is a positive image of a negative.

При этом имеют место случаи несовмещени  изображени  масочной пленки с изображением негатива при печати на позитивную пленку , вследствие усушки пленок или механических неточностей контргрейферной системы копир-аппарата. Кроме того, способ с использованием маски в слое требует специального про влени  негатива.In this case, there are cases of non-alignment of the image of the mask film with the image of the negative when printing on a positive film, due to the drying of the films or mechanical inaccuracies of the copy-grab system of the copier apparatus. In addition, the method of using a mask in a layer requires a special negative appearance.

Описываемый способ отличаетс  от известных тем, что в качестве маски применен флуоресцирующий экран, предназначенный как дл  просвечивани  негатива при печатании, так и дл  образовани  на нем флуоресцирующего позитивного изображени  с печатаемого негатива. Данный способ упрощает печатание цветоисправленных позитивов с цветных негативов, так как объедин ет процесс печатани  с процессами образовани  маски и цветоисправлени  печатаемого позитива.The described method differs from the known ones in that a fluorescent screen is used as a mask, which is intended both to trace the negative during printing and to form a fluorescent positive image on it from a printed negative. This method simplifies the printing of color-corrected positives from color negatives, as it combines the printing process with the processes of mask formation and color correction of the printed positive.

На чертеже схематически изображено устройство дл  осуществлени  этого способа.The drawing schematically shows a device for implementing this method.

Способ состоит в том, что во врем  печатани  цветного негатива на позитивную пленку последн   подвергаетс  не только экспозиции свечени  от равномерно освещенного экрана через негатив, но и добавочной экспозиции от флуоресцирующего экрана, свечение которого погашено, неравномерно по площади, освещением инфракрасными лучами через печатаемый негатив.The method consists in the fact that during the printing of a color negative on a positive film, the latter is not only exposed to light from the evenly lit screen through the negative, but also from the fluorescent screen, the glow of which is extinguished unevenly across the printed negative.

Устройство состоит из флуоресцирующего экрана 1, сменного фильтра 2, источника 3 ультрафиолетового света и оптической системы, в которую вход т: объектив 4, скоррегированный на полное линейноеThe device consists of a fluorescent screen 1, a replaceable filter 2, a source of ultraviolet light 3 and an optical system, which includes: lens 4, corrected to a full linear
