Shovel ink

Ordinary people’s habitual operation: due to the need of ink leveling, operators are used to holding an ink shovel to move back and forth on the ink roller to homogenize, add ink or shovel away the excess ink on the ink roller.

hidden danger

When the equipment is running at high speed, such operation is a dangerous operation with multiple accidents. Once the angle pin of the ink shovel is offset or the ink shovel encounters the uneven surface of the ink roller during operation, the ink shovel will be rolled between the main ink roller and the rubber roller and an accident will occur, ranging from scratching the printing plate or rubber roller to rolling the blanket or roller, Even in the moment of pulling out the ink shovel, personal accidents are caused by being in a hurry.

preventive measure

(1) First of all, stand firmly on your heels, concentrate, hold the ink shovel tightly, and don’t look around（ 2) When it is found that the local ink volume of the printed product is insufficient and the ink must be added manually, the ink shovel in the hand must be held tightly, and the small ink roller must be lifted. The operation can be carried out after the roller stops stably（ 3) When shoveling ink, the ink shovel shall rely on the main ink roller, lean on the rubber roller and shall not be suspended. The contact angle between the ink shovel and the ink roller shall not be less than 45 °.

Plate (blanket)

Ordinary people’s habitual operation: generally, there are many printing plates of the rotary machine, and the operators are used to hanging plates in two or more groups at the same time, so as to save time and improve work efficiency. At the same time, this phenomenon also exists in the plate loading of sheet fed offset press. In order to speed up the progress, and after the temporary version installation, the master also came to help, that is, one pressed the version and one clicked the switch.

Carton printing machine can be divided into the following two types according to their purposes:

1. General printing press: the so-called general printing refers to the printing method that uses convex, flat and concave formats, takes paper as the printing material, takes printing newspapers, color pages, picture albums and other general printing materials as the main object, and takes transmitting information as the main purpose, such as book printing press, newspaper printing press, etc

2. Special printing machine: printing machine for special printing, mainly including self-adhesive sticker printing machine, hose printing machine, etc.

According to the type of printing plate, there are four kinds of gravure printing machine, screen printing machine, lithographic printing machine and relief printing machine

1. Gravure printing machine: gravure printing is a printing method using gravure printing. Gravure press is a machine that uses gravure for printing. Intaglio refers to the printing plate with the graphic part lower than the blank part, mainly including engraving intaglio and photographic intaglio

2. Screen printing machine: screen printing is a kind of hole printing. The graphic part of the printing plate can be missed to the substrate through ink. The screen printing plate is meshed, and the plate forms two parts: through hole and through hole. During printing, the ink leaks from the through hole of the plate to the substrate under the extrusion of the ink scraper.

3. Lithographic press: a machine that uses lithography to complete the printing process. The graphic part and the blank part are almost on the same plane.

4. Letterpress: letterpress is a machine that uses letterpress to complete the printing process. The graphic part is obviously higher than the blank part of the printing plate, such as photographic relief plate, photosensitive resin plate, movable type plate, etc.
