Printing process of Christmas chocolate tin can

　　 The printing process of Christmas chocolate tin cans is divided into several processes: color separation, proofing, drawing determination, printing, determination of printing materials, coating, etc. The following SZM briefly introduces the printing process of Christmas chocolate gift tin cans.

1. Color separation is an important part of printing metal products: At present, the domestic and foreign iron printing equipment is mostly single-color printing presses and two-color printing presses. The first thing is to ensure that the color function of tinplate cans matches the original function provided by satisfied customers. In order to avoid excessive In color printing, overprinting is forbidden, scratching, significant color difference, not gorgeous colors, and many defective products. Spot colors are often used in tinplate instead of multi-color overprinting, such as Pantone. Mainly, to reduce the total area of ​​Internet access points, the smaller the expansion of printing outlets, and the better the printing effect.

2. Printing iron proofing: The first is to inspect the color separation film and pre-quality analysis and control of tinplate cans. In the proofing process, I want to keep the color separation sample as a reference in the printing process control, so that the printing quality is stable and the color can be It really reproduces the proofs recognized by customers. The editor warmly reminds us that we need to process into tinplate can products, put the contents, that is, forming experiments, such as food tin cans to test the tightness, shelf life, and freshness of the can.

3. Determining the drawings: Printing iron drawings should determine the three elements of tinplate positioning rules, product placement methods and the rubber roller used when the product is coated. The tinplate can positioning rules refer to the direction and size of the mouth and the body, which is printing The basis for making a pattern; the product placement method is that the printing method is based on the nature of the product, and the placement method is also different. In the process of determining the placement method, it is necessary to consider the minimum size and the maximum size that the printing iron can withstand. economic.

　　4. Plate printing: For the printing of tin cans and lids, most of the same pictures are grouped into negative or positive pictures according to the determined product drawings when manufacturing lithography, and the continuous printing machine is used for exposure and plate making.

5. Determine the printing data: Because the use of different products and molding equipment have different process requirements for the thickness, tin layer, hardness and annealing method of tinplate, we must determine the above elements according to the nature of the product. It must meet the printing requirements. It is necessary to meet the requirements of can making and box punching, and determine the final printing surface. The editor reminds that the general tinplate can printing uses the physical properties of repelling water and ink. With the printing pressure, the printing plate is transferred by the blanket. On the tin box, it belongs to the principle of offset printing.
