Printing machine roller
Technical Field
The invention relates to the field of printing devices, in particular to a printing machine roller.
Background
A printer is a machine that prints text and images. Modern printing presses typically consist of mechanisms for plating, inking, stamping, feeding (including folding), etc. The working principle is as follows: the method is characterized in that characters and images to be printed are made into a printing plate and arranged on a printing machine, then ink is coated on the position, where the characters and the images exist, of the printing plate by a person or the printing machine and then is directly or indirectly transferred to paper or other printing stocks, so that a printed matter identical to the printing plate is reproduced, a roller of the printing machine is a core component of a printing machine, the surface smoothness and the geometric accuracy of the roller of the printing machine can have important influence on the quality of the printed matter, and particularly when the fine printed matter is printed, the whole effect of the printed matter can be reduced by slight error, so that two sides of the printed matter are weakened or distorted.
However at present when carrying out long-time printing to comparatively crude paper, the debris card that is located rough surface rolls surperficial recess inside in the printing, and the inside that the inside debris of recess did not in time clear up the card full recess leads to being infected with chinese ink at the in-process debris that adds china ink when the side parallel and level of roller, influences the clarity of stamp during the printing, and simultaneously, the printing machine roller can remain partial chinese ink in the printing completion back surface, does not clear up for a long time and can cause roller roughness increase, influences the printing quality.
