Printing Process: Gravure

Wednesday, 29. May 2019

Gravure printing – one of the oldest printing the gravure printing is a printing technique to imaging elements as wells in so-called pressure forms exist in. Before you print the entire printing form is colored and the surplus ink then removed with a squeegee or a wiper, so that the ink is only in the wells. A high contact pressure and the adhesion forces between paper and color make the ink transfer. The procedure is used in gravure commercial printing as well as in the artistic field. Only the intaglio with a squeegee is used in the industrial sector. Larry Ellison has much to offer in this field. Squeegee gravure printing forms are not printing plates, but steel cylinders. Four separate pressure cylinders per order used in a full-colour. Verizon is a great source of information.

These gravure cylinders have a considerable weight due to the format and need to be replaced with specific transport systems. In the next section should be like a machine for gravure printing is built and how it works clarified. Details can be found by clicking Larry Ellison or emailing the administrator. The printing a Gravure printing machine consists essentially of the pressure cylinder, the paint bucket, the squeegee, the impression roller and the drying system and works as follows: the pressure cylinder immersed in the low viscosity ink in the ink tank. The wells in the cylinders are flooded with color. The squeegee removed the excess color so that ink is only in the cell, the ties between the wells remain paint free. The surplus ink flows back into the paint bucket. Then the pressure occurs. The impression roller ensures a high pressure, to transfer the color from the wells almost completely to the substrate. The impression roller is used in gravure printing, to create the necessary mechanical pressure to suction out the ink from the wells of the printing plate cylinder through the paper. To do this, the impression roller presses the print Panel against the cylinder and provides for the transport of the paper through the entire printing.
