1. Мозаичный светофильтр дл  цветной печати , содержащий параллельные между собой полосы субтрактивных фильтров трех цветов с равномерно измен ющейс  оптической плотностью в каждой, отличающийс  тем, что, сцелью сокращени  количества пробных отпечатков , в нем субтрактивные фильтры выполнены в виде треугольников, размещенных параллельно друг другу, а каждый из них составлен из полос одного цвета, параллельных одной из сторон треугольника.1. Mosaic color filter for color printing, containing parallel to each other bands of subtractive filters of three colors with uniformly varying optical density in each, characterized in that, in order to reduce the number of test prints, in it the subtractive filters are made in the form of triangles arranged parallel to each other , and each of them is composed of strips of the same color, parallel to one of the sides of the triangle. 2.Светофильтр по н. 1, отличающийс  тем, что оптическа  плотность полос каждого субтрактивного фильтра измен етс  от основани  треугольника к его верщине.2. Light filter on n. 1, characterized in that the optical density of the bands of each subtractive filter varies from the base of the triangle to its vertex. 3.Светофильтр по п. 2, отличающийс  тем, что направление изменени  оптической плотности в каждом субтрактивном фильтре одинаково.3. A light filter according to claim 2, characterized in that the direction of change in optical density in each subtractive filter is the same.
