The gravure process has the outstanding advantages of bright printed patterns, rich level reproduction capability, strong printing plate printing ability and wider range of base materials suitable for printing.
The intaglio printing process consists essentially of supplying the rotating steel embossing cylinder with ink through one or more stencil ink cylinders, which cylinder is provided with the pattern or image to be printed and is heated to a temperature of 80 ℃, after which the excess ink on the flat surface of the printing cylinder is wiped off by the rotating ink wiping cylinder, the ink remaining in the indentations of the printing cylinder being transferred under pressure onto the substrate to be printed. When pressure is applied to the stacked printed sheets, the residual tackiness of the ink being printed can cause the ink to adhere to the substrate surface on the back side of the next sheet, easily soiling other printed products. In order to reduce the problem of the ink sticking to the product to be printed in intaglio printing, the formulation of the ink is optimised.
