Abstract

The invention discloses a green and environment-friendly printing device and a printing method in the field of package printing. The green and environment-friendly printing device comprises a printing plate roller installed on a rack; the printing roller is provided with a dampening mechanism and an ink supply mechanism; the dampening mechanism is connected with a water storage bin fixed to the rack; the ink supply mechanism comprises an ink supply bin and a cooling bin; the ink supply bin is located in the cooling bin; the two ends of the cooling bin are communicated with the water storage bin and the dampening mechanism through a first communicating pipe and a second communicating pipe correspondingly; and a control mechanism is further arranged on the cooling bin and controls the flow of water entering the cooling bin from the water storage bin according to the viscosity of printing ink in the ink supply bin. According to the green and environment-friendly printing device provided by the invention,water in the dampening mechanism can be used for cooling the printing ink, and the situation that the viscosity of the printing ink is too small due to temperature rise, and the printing quality is affected is avoided; and the viscosity change of the printing ink can be measured in real time in the printing process, the temperature of the printing ink can be automatically adjusted, it is guaranteed that the printing ink has proper viscosity and fluidity, manual adjustment is avoided, the labor intensity of workers is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of packaging printing, and specifically relates to a green and environment-friendly printing device and a printing method. Background technique [0002] Lithographic printing is a common printing method. It uses the principle of immiscible water and oil to keep the printed part with a layer of oil film rich in oil, while the non-printed part of the layout can absorb appropriate water. Imagine ink on the layout Afterwards, the printed part repels water and absorbs ink, while the non-printed part absorbs water to form an anti-ink effect. This method is used for printing. [0003] During the printing process, the viscosity and fluidity of the ink change with the temperature. The higher the temperature, the lower the viscosity and the greater the fluidity. The viscosity and fluidity of the ink have a great relationship with the production process and the quality of the printed product. If the viscosity of the ink is to...
