Problems solved by technology

[0006] In the current color flexo printing technology, the overprint accuracy of each color group cannot be individually adjusted, and the overprint accuracy of the printed product is not high enough. The less the amount of ink, it is difficult to meet the requirements of color stability and fullness, and it is difficult to achieve the required ink film thickness under the condition of low ink transfer
The ink film cures slowly, the color of the printed product is not high, and the gloss is not good enough

Embodiment Construction

[0022] figure 1 It is a flow chart of the manufacturing method of the color flexo printing corrugated cardboard box of the present invention. Including the following steps:

[0023] Corrugated adhesive compounding glue 1: select surface paper weight ≥ 250g / m 2 , transverse folding resistance ≥ 50 times, water content 8 ± 2%, water absorption not greater than 60g / m 2 Corrugated cardboard, three-layer, five-layer or seven-layer corrugated board is bonded with adhesive and then glued;

[0024] Drying 2: send the glued corrugated cardboard into the drying box for drying;

[0025] Separation and cutting 3: Cut the corners of the dried corrugated cardboard neatly and divide them into required sizes;

[0026] Prepare ink 4: prepare ink with a viscosity of 15 seconds, a coloring rate of 90-100%, a fineness of ≤25, and a pH value of 7-9; the prepared ink is a transparent water-based ink.

[0027] Printing plate 5: Make a film according to the designed pattern, and then print the p...

Abstract

The invention discloses a manufacture method of a colorful flexible printing corrugated box, comprising six steps such as corrugated bonding, drying, throwing and cutting, preparing ink, forme and flexible printing. A corrugated cardboard with special standard is taken as a printing material, thus leading no settlement phenomenon between the corrugated peak and corrugated valley of the corrugated cardboard to occur and ensuring clear printed patterns. By adopting no-shaft transmission flexible printing, overprinting precision of each color group can be independently adjusted, thus improving the overprinting precision of the printed products, and greatly improving the printing quality. By adopting knurled rolls in grid shape and ceramic material spayed on the surface of the knurled rolls, the surface performance of the knurled rolls is improved, the flexible printing quality is improved, the service life of the knurled rolls is prolonged, and the printing cost is saved. The content of the connecting material in ink is increased and the consistency of dye is increased, thus reaching required ink film thickness under low ink transmission quantity, and reaching the requirement of stable and full colors, high vividness of the printed product and good glossiness.

Description

【Technical field】 [0001] The invention relates to a corrugated carton, in particular to a method for manufacturing a large-format color flexo-printed corrugated carton. 【Background technique】 [0002] With the development of commodity economy and science and technology, my country's packaging and printing industry has developed rapidly, especially the printing of wide corrugated boxes has obtained sufficient development space. Corrugated carton is the main material for commodity packaging, and its printing has a huge market. In recent years, large retailers, such as Wal-Mart and Carrefour, have made annual purchases of US$24 billion in the Chinese market, and will continue to increase in the next few years, which greatly increases the demand for beautifully printed corrugated boxes. demand. [0003] In recent years, the development of my country's household electrical appliances has maintained a good momentum, bringing new opportunities to the development of my country's n...
