SU4846A1 - A method of making transparencies for designing color images - Google Patents

Description

The proposed method is based on additive color synthesis, as well as photographic projection in natural colors with three lanterns, throwing onto the common screen three corresponding slides, each through its own filter: red ,, green or blue. All the variety of colorful shades is obtained by mixing in different proportions of the three light streams, painted in primary colors. The photodiapositives obtained by the orthochromatic semka of the original, written with ordinary pictorial techniques, are replaced in the proposed method; pictures on the glass, painted; gray colors of varying thickness, down to black, and representing themselves: the product of independent artistic creation. For this purpose | I need hardware different from I

from the photo projection so that the frames, which bear white glasses instead of transparencies, are quite accessible to the artist’s eye and brush; moreover, he must see the screen itself to control his work. Each stroke of gray paint on the glass causes an enlarged image on the screen in color, complementary to the optical filter. Thus, a smear in a red lamp gives a blue spot on the screen, a smear in blue, a yellow one. If both strokes are applied in such a way that the outlines of the images of both on the screen coincide, the spot will become green. With some skill in this way, it is possible to quickly produce an extremely effective projection for advertisements, decorations, posters, and so on. If it is desirable to transfer this result to paper by photomechanical means, then even orthochromatic is not required.

.Photo. It is enough to make a cliché with each handwritten slide and choose the appropriate ink for printing. 1This list is the first to try to apply additive synthesis in painting. In spite of the complexity of the equipment, the limited application and the special technique that still needs to be developed, in the author’s opinion, the described technique can be of great importance for the painting of the future. First, the artist opens up a combination of new paints, incomparable in their purity and brightness with muddy pigments, which they still had to work with. Secondly, the ease of reproduction by simple copying onto slide plates makes it possible to reproduce the original with all the richness of colorful shades. Thirdly, and this is the most important, it is easy to change not only the overall tonality of the picture on the screen, but also all the colors, when replacing some light filters with others. For example, a purple flower with green leaves can be instantly transformed into blue with red leaves, etc. Studying new achievements that are not available to the methods of old painting can help the artist to solve a number of pictorial problems.

The subject of the patent.

1. A method of making embossies for designing color images using the three-color ad-additive method by hand-drawing transparencies on a transparent material, characterized by the fact that on three simple glasses or transparencies that replace ordinary photographic transparencies with a three-color image design on the screen, three flashlights Through the appropriate color filters, the desired pattern is worn by hand with a stroke of gray paint of various colors that reach to black and shades; these brush strokes are distributed Simultaneously on all three glasses or films and controlling the resulting color and contour effects by direct observation of the image projected on the screen.

2. The use of slides made according to the method described in paragraph 1 to reproduce the resulting picture on paper in a photomechanical way without the aid of orthochromatic photographing, consisting in that from each of the three handwritten slides made cliché and selected for printing the appropriate ink .
