Problems solved by technology

The above method is only suitable for screen printing, generally suitable for printing on non-metallic substrates, and requires the use of UV coatings and metal inks for raw materials at the same time. The resin type is narrow and the process conditions are high. It is irreversible to have a matte effect first and then a glossy effect. Towards

Embodiment Construction

[0017] see figure 1 , The technological process of the present invention includes coating the outer coating, printing, coating the varnish layer, printing the varnish layer and printing the matte oil layer. The two processes of coating the outer coating and coating the varnish layer both adopt the full-page rubber roller coating method, and the varnish layer is coated with polyester resin or acrylic resin or epoxy resin, and the solid content is 35%~40% (mass percentage). Coating film thickness is 5-8g / m 2 . The three processes of external coating, printing and varnish coating are conventional metal packaging processes, and the unspecified parts belong to the existing technology. If the gloss effect is required, the finished product will be the finished product after completing the above three processes.

[0018] After coating the varnish layer in the method of the present invention, two steps of printing the varnish layer and printing the matt varnish layer are also include...

Abstract

The invention relates to a method of printing high-resistance glossy-matte metal. The method includes: coating the outer surface of metal, printing, and coating a glossy oil layer. The method is characterized in that a step of printing the glossy oil layer and a step of printing a matte oil layer are used after the step of coating the glossy oil layer, printing plates which are the same need to be independently made for the step of printing the glossy oil layer and the step of printing the matte oil layer, glossy oil and matte oil are transferred to the surface of a product through rubber cloth, the glossy oil and the matte oil are respectively independently solidified and dried by heating at 140-160 DEG C, glossiness of the glossy surface of the finished product is partially larger than or equal to 80 DEG, and glossiness of the matte surface of the finished product is smaller than or equal to 40 DEG. The method has the advantages that metal print with the whole surface which is both glossy and matte can be made by the method and the printed surface is well adhesive, scratch-resistant, good in printing stereoscopic impression and good in texture.

Description

technical field [0001] The invention relates to a method for printing on the surface of metal packaging, in particular to a method for printing mixed metal with high resistance gloss and matte. Background technique [0002] With the demand for personalized printing and product design differentiation in the market, special printing effects have always been expected by the market. Due to the particularity of the production equipment and process of metal packaging, the rear end of the printing equipment unit is equipped with a separate glazing machine. The machine adopts rubber roller roll coating method for varnish process. The production process of ink and varnish needs to be cured and dried by heating at 140-180°C. Although varnish and matte oil can be coated with a glazing machine, they need to be coated separately Moreover, the entire layout is completely covered, and it is impossible to achieve a large-area mixed effect of bright light and matte on the printing layout at ...
