The bright graphic design on the aluminum tube adopts the “four-color offset printing” processing technology, so how exactly is it used for production?
It is not practical to ignore the process of Aluminum Collapsible Tube production, from graphic design to the actual printing. Because nowadays consumers not only pay attention to the function of the product, but also care about its looking, therefore, all suppliers of aluminum empty tube hope to make it exquisite with the tube printing.
Offset printing is the most commonly used method for aluminum collapsible tube. This king of printing is lithographic. Its advantage is that it can print a large number of clear and sharp images quickly, and can make full use of the dots to print rich and multi-level color effects.
The working principle of offset printing is to first transfer the ink to a rubber-made drum impression, and then transfer it to the surface of the Aluminum Soft Tube. It is critical to get the graphic files prepared in the production of printed aluminum tubes. Taking four-color offset printing as an example, the finalized graphic design must first be correctly converted to the CMYK four-color mode, and then each color is converted into a negative for printing and plate making (called film). Before formal production, it is necessary to conduct trial production first and adjust the ink to the best ratio to ensure the effect of the finished product.
In summary, the “four-color offset printing” in the production of aluminum hoses refers to color prints made by color overprinting composed of the three primary colors of yellow, magenta, cyan and black.
