DE446627C - Process for the production of colored patterns in any color combinations and color changes in order to give certain prescribed shades of color to a single component or any number of components of the pattern - Google Patents

Description

It is known to produce prints or color photographs on glass, paper or the like to produce in modified colors that the printing forms, for example after a photographic three-part (color filter) recording obtained partial images in any different color combinations to colored patterns printed together or the partial images themselves are colored in this way and placed one on top of the other. This is purely experimental and left to chance without specific rules for achieving a specific shade and color combination worked.

The present invention relates to a method of making color combinations and color changes of a multicolored template of your choice or given To carry out regulation.

For example, to define the subsoil or a predominant one of a draft To produce paint in a certain prescribed hue is as follows proceed:

After the design (Fig. 1) a color sketch is made in which those components, for which a certain color has been prescribed are kept white (e.g. in Fig. 2 the reason α).

3d This color sketch becomes a double made, in which those parts of the pattern for which a certain shade is prescribed is black and everything else is white (Fig. 3, see reason α). From the color sketch (Fig. 2) a color photographic, for example a three-part (color filter) picture and of the Double (Fig. 3) taken an ordinary black-and-white photograph.

In this way, three partial negatives (Fig. 14) are obtained from the color sketch (Fig. 2), in which the component a, for which a certain color tone has been prescribed, appears black and by means of which, according to known methods, the color sketch directly using the Corresponding color filters in the original colors can be projected onto a screen or the like, but the reason α remains unexposed. By interchanging the color filters as desired and by using any other color filters, any desired colors and color combinations and rearrangements can be generated for the components b, c ', c ", d and e by projection.

The black and white photo (Fig. 15) of the double (Fig. 3 for a component a) according to the design (Fig. 1 or 13) shows all parts black with the exception of the one (α) for which the color is prescribed , and which has remained crystal clear. Using this negative and the filter of the color prescribed for the component α, a special lens or a special projection apparatus can still project the component α in the prescribed color into the projection image that is generated by means of the three-part color negatives and corresponding color filters. In this projection image, depending on the prescription or choice, by using appropriate filters for the negative of the double for the base α, any specific color can be produced.

In a corresponding manner, certain prescribed color tones can also be achieved for any number of components of the design (Fig. I). If you z. B. for two components α and b (Fig. Ι or 13) want to produce two specific prescribed colors, these two components α and b must appear white in the color sketch (Fig. 4), while for each component a double in It must be made in black and white (Fig. 5 and 6). The three-part color filter negatives of the color sketch are shown in Fig. 16, while the negatives of the doubles are shown in Figs. 17 and 18. They in turn serve directly as projection transparencies.

If, on the other hand, for all components of the design (Fig. 1) in this way according to regulations the color tones are to be produced, one only needs a draft in the outlines (Fig. 7 or 19) and for each one Component a double (fig. 8, 9, 10, 11, 12) according to the invention and a black-and-white negative produced accordingly (Fig. 20 to 24). By means of these single projection negatives produced for all components of the design In connection with the appropriate color filters, the complete pattern can be freely selected or project prescribed colors without the aid of a color photographic, For example, a three-part (color filter) image.

When individual parts of a pattern for which a certain color tone is prescribed If the drawing is tone-on-tone, the drawing must be in shades of gray so that this shading appears in the transparencies for projection occurs.

One wants to use slides of the color photographic recordings of the design (Fig. Ι or 13) work, those parts are shown in the original color sketch for which certain colors are prescribed, executed black instead of white and as a result also preserved black in the projection slides.

With the present invention you have it completely in hand, both a finished supplied multicolored picture or pattern in certain directions, which one can prescribe to change the colors arbitrarily as well as only one from scratch The present pattern drawn in black and white according to the new process by choosing appropriate colors for the individual To build up parts of the pattern and so the most favorable color combinations depending on certain tastes or To locate color regulations.

An excellent advantage of the invention is that you can choose from the cheapest Projection images of color photographic, for example three-part (color filter) Take pictures and limit yourself to only these most favorable color combinations of the many possible changes to manufacture in printing. Significant savings in time and costs are thus achieved.

Claims (2)

Patent claims: i. Process for the production of colored samples in any color combination and rearrangements, characterized in that a color sketch is carried out from the draft that the components of the pattern, for which certain color tones are prescribed, are white (for negative projection plates) or black (for slides) and for each of these components a double, in which these components are kept black and everything else is white are, on which of these doubles ordinary black and white negatives for directly projecting these components of the pattern using appropriate filters with prescribed Shades are produced, while the color sketch is a color photographic, for example a three-part (color filter-j picture taken and these partial negatives directly to any colored side-by-side and on top of each other pro j ize can be used, or it will be used instead of by means of the partial negative means partial slides produced therefrom are projected. 2. Modification of the method of making colored samples in any Color combinations and rearrangements, characterized in that 10g so many duplicates how different colors should be used, and then a projection negative which are the relevant components of the pattern each project alone to the overall picture, and that by switching on any color filter to be selected, the pattern in Any number of color combinations and color changes can be created. 1 sheet of drawings.
