Compound hose flexo printing process

Before printing, we must first make a feasibility analysis of the prepress process. When receiving the sample of the toothpaste tube provided by the customer, carefully analyze the designer's design focus, determine the main screen (such as the product's brand identity, product background level, etc.) and the auxiliary screen (such as the product's text description, product composition, Weight marking, etc.) Determine the color number and color sequence of the product colors, perform appropriate scaling on the color of two or more fasteners, and add the tube cursor and filling to the sample draft according to the customer's requirements. cursor. After completing the above preparatory work, the revised sample will be submitted to the plate making company.

Then, the anilox roller of each color unit is configured with reference to the pattern of each color of the printing plate (such as solid, line, halftone, gradient, etc.) and the color concentration of each color, and it is made when proofing. Final adjustments to restore the color to its best condition. Our factory has deployed dozens of anilox rollers for hose printing. The number of network lines is 250 to 800 lines/inch, and the BCM value is in the range of 3.0 to 12.0. When printing the field version, use an anilox roller of 250-400 lines/inch, an anilox roller of 400-600 lines/inch for printing text and line printing, and 550-800 lines for printing halftone and gradient printing. Inches of anilox roller. After selecting the number of lines of the anilox roller, the BCM values ​​of the same line number of anilox rollers are also compared, so that the final selected anilox roller configuration is more reasonable and the color reproduction is closer to the original color. Then you can do the printing operation.

The Jetlas EM410 flexo printing press is equipped with 8 color group full UV printing units and 2 sets of die cutting and slitting units. The main program for printing production is: on the upper composite sheet roll material → go material → adjust the corrective device → install each color group anilox roll → install the plate roll → adjust the anilox roll, plate roll, between the impression roll Pressure → Embossing → Adjusting tension → Register printing → UV ink curing → Cutting composite sheet → Winding.
