Tell about the importance of color printing packaging

  The color separation process in Dalian color printing packaging is used to digitally scan the originals and divide the originals into red, green and blue. Prior to the development of digital imaging, the traditional method of color separation was to take 3 pictures of the image, each with a corresponding color filter to filter different light. However, after the color separation, the desired result is 3 gray images representing the originals of red, green and blue. The development of color printing and packaging industry has become more and more important in packaging making. The success or failure of the current market competition depends to a large extent on the packaging of the goods, and the quality of the packaging is decided by the surface treatment of the goods after printing.

  The printing process requires that the pH value of the paper be neutral. However, because in the papermaking process, the sizing material, filler properties and pigment composition difference, may make the paper either acidic, or alkaline. For example: Sizing with Vaseline in the papermaking process, there is a certain residual chlorine and organic acid in the slurry, if not properly handled, the paper will produce acidic; application of caustic soda in making a process (NaOH) and alkaline filler and pigment, paste in residual alkali liquid, and not make the necessary processing, the paper will make alkaline. Packaging and printing enterprises should pay attention to their comparative advantages and make accurate market positioning according to their own central technology. As in the "packaging design and production enterprise", "multi function packaging material manufacturing enterprise", and not entirely with "packaging printing, packaging materials, positioning, positioning of the enterprise to stand the test of enterprise development.
