Description

1. Technical field [0001] The invention belongs to the technical field of printing ink cleaning, and specifically relates to an ink cleaning agent for cleaning ink rollers and blankets in the printing industry and a preparation method thereof. 2. Background technology [0002] Frequent maintenance and maintenance of the ink rollers and blankets of the offset printing machine is the basic guarantee for printing high-quality printed matter. The main means of maintaining the ink roller and blanket is to clean, that is, to use a cleaning agent to clean off the remaining ink and other impurities on the ink roller and blanket. [0003] For the cleaning of printing ink, it can be divided into three situations: one is routine cleaning after printing every day, the other is color-changing cleaning before changing the ink color, and the third is regular and thorough maintenance cleaning. Although the cleaning agent is an auxiliary material for printing, its economic and social benefi...
