Description

Предлагаемый способ фотомеханической корректуры цветоделенных негативов путем маскировани  позвол ет изготовл ть цветоделенные негативы дл  фотомеханической репродукции способом двойной экспозиции.The proposed method of photomechanical correction of color-separated negatives by masking allows the production of color-separated negatives for photomechanical reproduction using a double exposure method.

Этот способ позвол ет достаточно полно устранить цветоделительные искажени  и получить значительно более полную цветоделительную корректуру во всем интервале плотностей , где соблюдаетс  их аддитивность .This method allows one to sufficiently eliminate color separation distortions and to obtain a much more complete color separation correction in the entire density range, where their additivity is observed.

Осуществление способа достигаетс  следующими приемами: а) фотографируют оригинал с применением основного дл  выдел емой краски светофильтра, но без про влени  фотопленки; б) фотографируют тот же оригинал с применением маскового дл  данной краски светофильтра и получают негативную маску, градационна  крива  которой должна обладать посто нным в одних случа х или переменным вThe implementation of the method is achieved by the following methods: a) photograph the original using the light filter main for the selected paint, but without displaying the film; b) photograph the same original with the use of a filter mask-type paint and get a negative mask, the gradation curve of which should have a constant in some cases or variable in

других случа х градиентом; в) фотографируют оригинал на уже экспонированную , по не про вленную пленку с применением того же маскового светофильтра, с которым была получена негативна  маска, поместив на фотопленку эту маску .other cases by gradient; c) photograph the original on the already exposed, not-developed film using the same mask filter with which the negative mask was obtained by placing this mask on the film.

Предмет изобретени Subject invention

Способ фотомеханической корректуры цветоделепных негативов путем маскировани , о т л и ч а ю щ и и с   тем, что, с целью уменьщени  цветоделительного искажени , цветной оригинал фотографируют через основной дл  выдел емой краски светофильтр , затем на тот же светочувствительный материал через масковый дл  выдел емой краски светофильтр фотографируют оригинал вторично, наложив на светочувствительный слой негативную маску, полученную фотографированием оригинала с тем же масковым светофильтром .A method of photomechanical correction of color-separation negatives by masking, in order to reduce color separation distortion, a color original is photographed through a light filter, basic for the color being extracted, and then on the same light-sensitive material through a mask for selection. The color of the light filter is used to photograph the original for the second time by applying a negative mask on the photosensitive layer obtained by photographing the original with the same mask light filter.
