Example Embodiment

[0019] Example 1:

[0020] Using decorative original white paper as the base material, a six-roller gravure printing machine is used for multi-color overprinting. The first four plate rollers are printed to form patterns and the latter two plate rollers are printed to form a three-dimensional concave-convex effect.

[0021] The first four plate rollers use colored ink without adding high solid content resin; and the ink components on the latter two plate rollers are: high solid content resin 75% and solvent 25%. Among them, the high solid content resin adopts polyol acrylate (purchased through commercial channels).

[0022] The first four plate rollers use electric engraving, and the last two plate rollers use laser engraving plates. After the decorative paper is overprinted, it is baked at 100°C and quickly rewinded at a speed of 100m / min to form a finished product of solid embossed decorative paper.

Example Embodiment

[0023] Example 2:

[0024] The ink components on the latter two plate rollers of this embodiment are: polyester acrylate 20%, castor oil alkyd resin 30%, nitrocellulose 20%, and solvent 30%. Others are the same as in Example 1.

Example Embodiment

[0025] Example 3:

[0026] The ink components on the latter two plate rollers of this embodiment are: coconut oil alkyd resin 55%, amino resin 25%, and solvent 20%. Others are the same as in Example 1.

Abstract

The invention relates to stereoscopic relief decorative paper and a printing method thereof. Floral patterns with stereoscopic concave-convex sense are arranged on the decorative paper, and the concave-convex thickness of the floral patterns is between 0.05 and 0.8 millimeter. The method for printing the stereoscopic relief decorative paper comprises the following steps of taking decorative pure white paper as a base material and adopting a multi-roller gravure printing machine to perform multi-color overprinting to form stereoscopic floral patterns on the decorative paper, wherein printing ink on at least one roller contains high-solid-content resin with the weight ratio of between 10 and 95 percent. People can truly tell the meticulous engraving of the patterns of the stereoscopic relief decorative paper provided by the invention from any angle. Therefore, the paper has extremely strong competitiveness and broad market prospects.

Description

(1) Technical field [0001] The invention relates to a three-dimensional embossed decorative paper and a printing method thereof. (2) Background technology [0002] The printing technology of decorative paper is relatively mature. It is mainly based on decorative original white paper, with yellow, magenta, blue, black, white and other color inks, color matching according to the requirements of various patterns, and patterned intaglio rollers (with wood grain, stone grain, art Patterns, etc.) of each color plate, the ink is soaked through the ink storage tank, the excess ink is scraped off with a scraper, and the decorative original white paper passing through it is pressed on the pattern plate roller with a rubber roller, and the ink is transferred and adsorbed. The surface of the original white paper is dried in an oven at 60°C-150°C, printed in each color sequentially and neatly overlapped as required (with 1-8 sets of colors), and finally forms a decorative paper with a c...
