Method for expressing three-dimensional visual effect of image text

Abstract

The invention discloses a method for expressing a three-dimensional visual effect of an image text, and relates to a method for expressing an image-text stereoscopic vision effect directly without backlight. The two problems to be solved are to improve production benefit by reducing the counterpoint difficulty of gratings formed by hot pressing and three-dimensional pictures and enhance the three-dimensional visual effect of the image text and to improve the rough sense of a picture by improving the accuracy of the gratings formed by the hot pressing. In order to solve the technical problems, the invention adopts a technical scheme that the method comprises the following steps of: printing a synthesized three-dimensional image text on a printed material 1, and manufacturing a grating die matched with the three-dimensional image text in advance in an ironing head of hot stamping equipment; and bonding a transparent membrane on the surface of the image text, and performing the hot pressing to form an equidistant orthohexagonal spherical grating 2, so that the image text has the three-dimensional visual effect. The method is mainly used for product packages, books, advertising and the like which express the three-dimensional visual effect of the image text directly without the backlight.

Description

technical field [0001] The invention relates to a method for directly expressing graphic and text stereoscopic visual effects without backlight Background technique [0002] Chinese Patent Publication No. CN101585292, published on November 25, 2009, the name of the invention is a method for making pictures and texts have stereoscopic effects. This invention application discloses a method for making pictures and texts have a stereoscopic effect. The distance and shape of the lenticular lenses match the text, and the film is adhered to the surface of the text, and a grating is formed after hot pressing, thereby producing a three-dimensional visual effect. [0003] Its disadvantages are as follows: First, in this method, when the equidistant lenticular gratings produced by hot pressing are aligned with the lines in the three-dimensional picture, the degree of texture matching required by the two is very high, and the texture matching state It must be stable, but there are obj...

Problems solved by technology

[0003] Its disadvantages are as follows: First, in this method, when the equidistant lenticular gratings produced by hot pressing are aligned with the lines in the three-dimensional picture, the degree of texture matching required by the two is very high, and the texture matching state It must be stable, but there are objective defects in the hot stamping equipment itself (such as: machining accuracy error, mechanical vibration during production, wear), so in the production process, it is difficult to align the grating and three-dimensional graphics, and the scrap rate is high Second, this kind of method, based on the limitation of current conventional computer hardware, design software and output device precision (2400dpi), the raster precision that can produce is relatively low, and the three-dimensional picture that produces by printing mode or digital printing mode aligns position Finally, the three-dimensional space of the picture is not large enough, and the grating stripes of the picture are obvious, and the three-dimensional visual effect is not delicate enough
