Stereo printing processing method

The present invention provides a method for processing a three-dimensional printing, in particular, a plurality of ink layers printed with irregularities on the surface of the printed matter according to the density of the color pixels, and then according to all the original color pixels in the original image. The surface of the plurality of ink layers is printed with a color layer, whereby the surface of the printed matter is presented with a three-dimensional relief effect.

According to the development of today's technology, printing technology has also been printed from previous flat images, and a three-dimensional printing technology that can display inkjet embossed color patterns on the surface of printed matter has been developed. The existing three-dimensional printing technology is multi-layered by a UV color inkjet machine to deposit a plurality of ink layers (such as white ink or color ink) on the surface of the same printed matter (such as paper, plastic board, wood board, iron plate or ceramics). Further, a color ink is printed on the surface of the ink layer, thereby enabling the surface of the printed matter to exhibit a three-dimensionally convex color pattern.

Before using the UV color inkjet printer or other printing methods such as screen printing to perform the printing operation, the image processing software such as PhotoShop, CorelDRAW, Painter or Ulead Photo Express must be used for each block in the original image file. The color pixel performs the setting of the thickness value of the ink layer, so that the UV color inkjet machine can discriminate the thickness value of the ink layer of each color pixel for subsequent layered micro-spraying action on the surface of the printed matter, thereby making the surface of the printed matter The visual effect of the three-dimensional relief is presented.

However, since the original image file needs to set the ink layer thickness values of the color pixels of each block one by one before the output printing, the image processing operation of the original image file is too complicated, and the ink layer thickness value is not adjusted. The block, which in turn causes the UV color inkjet machine to complete the inkjet printing operation, the pattern of the surface of the printed matter may exhibit excessive or too small three-dimensional undulations, and the three-dimensional relief effect that the original is desired to achieve.

Therefore, how to solve the problem that the image processing operation of the original image file is too complicated and easy to produce the error of adjusting the thickness of the ink layer is the direction for the relevant manufacturers engaged in the industry to research and improve.

Therefore, in view of the above-mentioned deficiencies, the inventors have collected relevant information, and through multiple assessments and considerations, and through years of experience in the industry, through continuous trial and modification, the design of such main layer, sub-layer and The concentration of each color pixel in the key layer is such that the plurality of ink layers are printed and formed on the surface of the printed matter without undulating the thickness of the ink layer of the original color pixel of each block in the original image. Approach.

The main object of the present invention is to deal with a method for processing a three-dimensional printing by first performing a color conversion operation on the original image file to generate a gradation color gradation, and then based on the original color pixels in the original image file. The surface of the ink layer is printed with a color layer, so that the surface of the printed matter can exhibit a three-dimensional relief pattern.

A secondary object of the present invention is to print a plurality of ink layers having irregularities on the surface of the printed matter in the main layer, the sub-layer, and the key layer, and to print the surface of the printed matter. The main layer and sub-layer are formed with basic The embossing effect is further enhanced when the key layer is printed on the surface of the printed matter to enhance the convex effect of the visual focus, and then the color layer is printed on the surface of the plurality of ink layers according to all the original color pixels in the original image file. Thereby, the surface of the printed matter is presented with a three-dimensional relief effect.
