preparation example Construction

[0034] The present invention provides a method for preparing a new type of matte effect packaging material, including the following process flow: design matte effect patterns, select optical effects based on the effect patterns, quantify the optical effects, simulate the optical effects to determine the matte effects and images Unit, and then group the image units and make a plate by photolithography to prepare a master, and finally copy the frosted information on the master to the substrate to obtain a packaging material with a new frosted effect.

[0035] The specific process steps are as follows: matte effect design: use graphic processing software to design the matte effect required; optical effect selection: select the corresponding optical effect expression form according to the matte effect designed; optical effect quantification: quantify optics according to the matte effect The effect of grayscale, angle, depth and other parameters; optical effect simulation: use the corr...

Embodiment 1

[0045] Step 1: Design

[0046] Use graphic processing software to design a rainbow matte effect, such as figure 1 As shown, the matte effect is a full-page effect, with silver-white highlights in some areas. In the absence of particularly bright light, three-dimensional small particles can be perceived in the visual effect, and random silver-white dots can be seen at the same time. When under bright light conditions, in addition to the silver frosted effect, you can also observe random flashing points of rainbow light. Has a rainbow matte effect.

[0047] Step 2: Optical effect selection

[0048] According to the matte effect of the design, two optical effects of lens and grating are selected.

[0049] Step 3: Quantification of optical effects

[0050] According to the frosted effect, the two optical effects of quantization lens and grating, the lens is a non-circular structure Fresnel structure, the grating is a platinum beam, the lens and grating parameters: gray value range 45-200,...

[0064] Step 1: Design

[0065] Use graphic processing software to design a highlight matte effect, such as image 3 As shown, the frosting effect is a full-page effect. In the absence of particularly bright light, three-dimensional small particles can be perceived in the visual effect. When under bright light conditions, in addition to the three-dimensional frosting effect, you can also observe The effect of glittering particles.

[0066] Step 2: Optical effect selection

[0067] According to the matte effect of the design, three kinds of optical effects are selected: lens, grating and sand silver.

[0068] Step 3: Quantification of optical effects

[0069] According to the matte effect, the three optical effects of lens, grating and sand silver are quantified. The lens is a non-circular Fresnel structure, the grating is a dynamic grating, and the sand silver is a dynamic sand silver. The lens, grating and sand silver parameters: gray value range 45 -200, the angle value range is 0-18...

Abstract

The invention discloses a method for preparing a novel packaging material with a frosted effect. The method comprises the following steps of designing a pattern with the frosted effect, selecting an optical effect according to the pattern with the frosted effect, quantifying the optical effect, simulating the optical effect to determine the frosted effect and image units, assembling the image units, then photoengraving to prepare a mother set, and finally copying frosted information on the mother set to a substrate to obtain the novel packaging material with the frosted effect. The problems that a frosted or matte effect layer of the existing frosted material in the background art is uneven in surface, and is dim and dark and poor in metal texture visually, small in visual impact, and lowin gloss are solved, so that the novel packaging material with the frosted effect has a relatively strong metal texture, a relatively strong three-dimensional sense, a large visual impact, and high anti-counterfeiting performance, and is rich in variety, and high in selectivity.

Description

Technical field [0001] The invention belongs to the technical field of packaging printing materials and decorative materials, and specifically relates to a preparation method of a novel frosted effect packaging material. Background technique [0002] The frosting effect is widely used in various high-end packaging with its noble and beautiful bright sand feel and stable and reliable anti-counterfeiting. The matte effect of the existing materials is mainly formed by different processing methods on the surface of the substrate to form an uneven structure, and the light is irradiated on the surface to form a diffuse reflection, showing a foggy matte visual effect. The commonly used processing methods mainly include printing, transfer, and embossing. , Coating, etc. [0003] 1) The printing method is to print the frosted ink on the substrate by means of screen, gravure, etc. During the curing process of the ink, due to the change of the surface energy of the filler, the film-forming m...
