Main technical parameters

Printing Principle of Computer Registered Rotogravure Printing Press

Computer registered rotogravure printing press is in letterpress printing, the whole plate cylinder is inked, and the ink on the blank part of the plate is scraped off by the scraper, and the ink on the graphic part is left, and then the paper is passed through the press. The printing cylinder imprints on the back of the paper, so that the ink in the concave part is directly transferred to the paper surface, and finally the printed matter is piled up or rewound through the receiving part, so that the printing process of the gravure printing machine is completed

Precautions of computer registered rotogravure printing press

1. During operation, do not put your hands into the running parts of the computer registered rotogravure printing press, especially the pinch roller. 

2. When checking the computer registered rotogravure printing press, the main power switch on the main control cabinet must be turned off. 

3. When the computer registered rotogravure printing press is stopped for operation and adjustment, the stop button should be locked. 

4. When doing electrical inspection, turn off the main power supply. 

5. When feeding and cleaning the hot roller in the drying oven, be sure to turn off the heat source first. 

6. Before starting the computer registered rotogravure printing press, it should be confirmed that the exhaust air of the drying box and the ventilation of the workshop are normal.

What is the difference between gravure and rotogravure?

Gravure printing is an intaglio printing process; that is, it involves engraving an image onto an image support. In rotogravure, images are acid etched onto the surface of metal cylinders—one cylinder for each color—in a cell pattern. Unlike letterpress or letterpress printing, in which the image is raised, or offset printing, in which the image is flush with the printing plate, so that the cells are recessed into the cylinder. The cylinders are etched with cells at different depths. These cells hold the ink that is transferred to the substrate. The size of the cells must be precise because darker cells produce more intense colors than lighter ones.

The chamber is filled with ink, and the ink is wiped or scraped off the non-printing parts of the plate or cylinder by a squeegee. The paper or other substrate is then pressed against an inking cylinder on a web press, and the image is transferred directly to the media, unlike offset printing, which uses an intermediate cylinder. The engraved cylinder is partially submerged in an ink fountain, which picks up ink to fill its sunken cells with each revolution of the press.

Flexographic printing (rotogravure) uses printing plates with raised surfaces (letterpress printing) and fast-drying fluid inks to print directly onto printed materials. These plates are made of rubber or a light-sensitive polymeric material called photopolymer and are attached to cylinders on rotary printing equipment. Flexographic printing is performed from a flexographic printing plate wound on a rotating cylinder. The plates are usually attached to the cylinder with double-sided tape.
