Description

Offset printing ink color development instrument

technical field

The utility model belongs to the technical field of printing machinery and is used for displaying offset printing ink for color proofing, in particular to an offset printing ink color display instrument.

Background technique

Before printing spot color inks, it is necessary to check whether the color of the prepared ink is consistent with or sufficiently similar to the target color. If the prepared ink is printed on a printing machine and then checked with the target proof, it will cause a large waste of paper, ink and time. Therefore, a simple and easy-to-use equipment is needed to spread the prepared ink evenly and with a controllable thickness. On paper, used to showcase spot color inks for color proofing. Existing technology, such as CN201645981U, discloses a color development instrument, through which the ink distribution roller and the ink form roller contact each other and roll, and the ink distribution roller performs axial serial movement at the same time, so that the ink is evenly distributed on the ink form roller, and then the paper Clamped on the impression cylinder, the ink form roller is moved horizontally to press on the paper. When the impression cylinder rotates, it drives the ink form roller to rotate, so that the ink on the ink form roller is imprinted on the paper, which is used to check the color of the ink on the paper. However, in this kind of color development instrument, the ink form roller is located between the ink distribution roller and the impression cylinder, so it is difficult to clean; when the thickness of the paper changes, it is necessary to adjust the distance between the ink form roller and the impression cylinder, and the operation is more troublesome; The rotation directions between the roller and the ink form roller, and between the ink form roller and the impression cylinder are relative movements, and it is easy to squeeze the operator's fingers during the printing and cleaning process.

When cleaning the ink roller after printing, the ink form roller and ink distribution roller can be separated, and the cleaning operation is very easy. The printing pressure is generated by the compression deformation of the compression spring. A slight change in the thickness of the paper has little effect on the compression of the compression spring, and there is no need to adjust the pressure due to the change in the thickness of the paper. When distributing ink, the ink form roller presses on the ink distributing roller by its own weight, and rotates outward; cleaning the ink roller can be completed in a stop state, avoiding the danger of pinching fingers.
