Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to an ink mixing device for a printing press. Background Technology

[0002] This technology utilizes printing presses, including but not limited to gravure printing equipment, a direct printing method characterized by using recesses engraved on a printing plate to hold ink, and transferring the ink from the recesses to the substrate through pressure. This high-resolution gravure printing offers advantages such as high image clarity, good anti-counterfeiting performance, strong printing durability, and a wide range of printable materials. The gravure printing equipment is equipped with an ink trough, and ink is fed using inking rollers. Ink preparation, also known as ink mixing or ink adjustment, primarily involves adjusting the printability of the ink during the printing process or using subtractive color mixing. Because ink preparation must be carried out in an air-isolated environment and involves relatively small dosages, there is currently no ink preparation equipment available for gravure printing.

[0003] Therefore, there is an urgent need to develop an ink mixing device for printing presses that is simple in structure and reliable in operation. Utility Model Content
