Description

The invention relates to the field of arts and crafts.

From the technical field, various solutions are known concerning methods of obtaining a multilayer relief image (see, for example, patent RU 2232082 C1, published 10.07.2004, patent RU 180504 U1, published 14.06.2018). However, the known analogs have a number of disadvantages, such as insufficiently realistic image detail and reduced mechanical stability.

The task of the claimed group of inventions is to eliminate the disadvantages of the prior art. The technical result of the claimed group of inventions is to provide increased detail, a clear outline, increased mechanical stability.

The problem is solved, and the technical result is achieved through the claimed group of inventions, which can be used for the production of tactile works of art and relief aids for the blind, the creation of artificial relief for works of art and photographs, the creation of works of art for decorative purposes.

The relief when printing with UV-curable inks is formed by multilayer printing of a specially prepared file in several passes of the printer's print head with the maximum amount of ink. The number of passes is set based on the maximum required relief height based on the thickness of the printing layer for this printer.

1. Work on tactile copies of paintings.

Making a tactile picture for the blind and visually impaired includes the following steps:

1 / compilation by an art critic of a description of the picture with an orientation to the subsequent typhlo commentaries.

2 / on the basis of the description of the tiflos specialist, zones for creating a relief, methods of transmission, boundaries and textures of elements of a pictorial work are determined.

3 / creation of a bump map based on the characteristics of the printing device. When printing in one layer by filling C-100 M-100 Y-100 K-100, the coating thickness is 0.1 mm. For 10 layers, 1 mm comes out. For pouring C-50 M-50 Y-50 K-50 - 0.05 and 0.5 mm, respectively. Other heights are obtained in the same way. A sharp border of the fill makes the relief a step, a smooth gradient is a beveled or sloping relief.

4 / when preparing the file, determine the number of successive layers that will form the relief similar to the level isolines in cartography.

5 / form each layer separately in black. Set each layer to 100 / n% transparency, where n is the number of layers, and set the blending mode to "multiplication".

6 / form a white substrate under all layers. Get the first base layer.

7 / in separate layers draw the necessary elements for detailing.

At the same time, the boundaries of important elements are monitored. The boundaries should be separated from each other by terrain levels.

8 / make a gap of at least 3 mm between adjacent elements.

9 / the degree of overlap (the level of elevation of the relief) is controlled by the transparency of the layers. To give a texture similar in feel to the texture of the paint on the canvas, copies of the selected areas of the image are used using the "color contrast" filter with additional curve correction. If necessary, increase the difference between the levels, using additional lightening with white color using the selection mask - highlight the areas near the border of the sharp drop in levels with a "soft brush".

10 / save the main layer, the layer with details and textures in separate tif files.

11 / for each file, they carry out the procedure for converting to CMYK with a maximum overlay of colors: desaturate the image (so that all RGB channels are the same). Levels check the black point. Copy any channel. Split channels and then collect them in CMYK. Save.

12 / when printing, control the overlap of ink layers. If it is necessary to additionally raise individual elements, create a separate file with them. After printing the relief, the entire surface is printed in white in 2 layers. Then the original color image is printed. Since UV inks have high safety and resistance to external influences, it is not necessary to additionally protect the images during normal indoor use.

2. Work on relief copies of paintings includes the following stages:

1 / zones for creating a relief, methods of transfer, boundaries and textures of elements of a pictorial work are determined.

2 / creation of a relief map based on the characteristics of the printing device. When printing in one layer by filling C-100 M-100 Y-100 K-100, the coating thickness is 0.1 mm. For 10 layers, 1 mm comes out. For pouring C-50 M-50 Y-50 K-50 - 0.05 and 0.5 mm, respectively. Other heights are obtained in the same way.
