Problems solved by technology

It can be seen from the above printing process that the existing technology needs to go through two printing processes, the production cycle is long and the efficiency is low
To obtain this dual printing effect, the matting powder used is generally a mixture of industrial paraffin and ultrafine silica, and the

Example Embodiment

[0015] Example 1

[0016] Preparation of matting powder (the following raw materials are parts by weight): Take polyethylene paraffin 90, hydrogenated castor oil 2, and polyacrylamide 0.5 that are fluffy and fluffy, and mix the three evenly in a high-speed mixer to obtain matting powder.

[0017] In this embodiment, the gravure printing equipment is made in Italy: Cerudi 10+1 in-line compound transfer gravure printing machine. The double-gloss one-time printing method of the present invention includes the following steps: the gravure ink and the matting powder are mixed uniformly in a weight ratio of 10:3, and then the mixed matte gravure ink is used on the substrate. The matte pattern is printed on the part where the matte effect is obtained, and then the gravure ink without matting powder is used to print the light pattern on the base material where the light effect is required.

[0018] After testing, the matte gloss is 50%.

Example Embodiment

[0019] Example 2

[0020] Preparation of matting powder (the following raw materials are parts by weight): take the fluffy polyethylene paraffin 93, hydrogenated castor oil 3, and polyacrylamide 0.7, and mix the three uniformly in a high-speed mixer to obtain matting powder. The rest is implemented as in Example 1.

[0021] After testing, the matte gloss is 55%.

Example Embodiment

[0022] Example 3

[0023] Preparation of matting powder (the following raw materials are parts by weight): take polyethylene paraffin 95, hydrogenated castor oil 4, and polyacrylamide 1, which are fluffy and fluffy, and mix the three evenly in a high-speed mixer to obtain matting powder. The rest is implemented as in Example 1.

[0024] After testing, the matte gloss is 57%.

[0025] The matting powder of the present invention can be used for both gravure printing ink and offset printing ink.

Abstract

The invention discloses a method for printing double smooth surfaces at one time and a matting agent for printing ink. The matting agent is prepared from the following raw materials in part by weight: 90 to 95 parts of polyethylene paraffin scattered in a fluffy state, 2 to 4 parts of hydrogenated castor oil and 0.4 to 1 part of polyacrylamide. The preparation method comprises the following step of uniformly mixing the three substances in a high speed mixer. The method for printing double smooth surfaces at one time comprises the following steps: uniformly mixing gravure ink and the matting agent in a ratio of 1:(2-4); printing matted patterns on parts of a base material requiring a matting effect through gravure equipment by using the mixed matting gravure ink; and printing bright patterns on parts of the base material requiring a bright effect by using gravure ink without the matting agent, or reversing the sequence to achieve the same effect.

Description

technical field [0001] The invention relates to the field of packaging printing, in particular to a printing method with double smooth surfaces and a matting powder for ink. Background technique [0002] Matte patterns and glossy patterns are generally printed on the surface of packaging boxes for high-end wine, cigarettes and other items. The matte pattern is not dazzling and dazzling, stable and elegant, and has a hazy beauty, while the glossy pattern is smooth and bright, giving people a gorgeous and bright feeling. When the two patterns are arranged together, they will form a strong gloss contrast and increase the layering of the pattern. At present, to obtain this double printing effect, the printing process is as follows: first, a layer of glossy ink is printed on the surface of the printed matter, and then a layer of partial matte ink is printed on the surface of the glossy ink, and the parts with matte ink have a matte effect. The parts that are not printed with ma...
