Principle of ink printing machine

The principle of the water-based ink printer is of course to use the water brush method. Ink printing is a special printing technology that can show subtle color changes on the carrier. The ink used in the water-based ink printer needs to be diluted and dissolved to ensure the smoothness of color printing. Since the light color printing of diluted water-based ink is more expressive than the light color of ordinary spot colors, designers often use diluted water-based ink for water-based ink printing to form a light background on paper for subsequent four-color printing.

After everything is ready, stick the dried resin plate on the 4mm base paper, and then stick it on the plate cylinder according to the specified size, and then use industrial ethanol to adjust the viscosity of the water-based ink in a 1:1 ratio. Then start the ink pump, apply ink, turn the ink roller until the ink amount is even, check the ink amount, the ink is evenly distributed on the ink roller, and the reticulated pattern is vaguely visible. Then start the test printing. If the text is not clear and the bottom is exposed, the printing pressure can be adjusted appropriately. It should not be too large to avoid deformation of the printing plate; if the text is blurred and the lines are not clear, the amount of ink can be reduced until the text is clear, the lines are clear, and the dots are not deformed.

The water-based ink printing machine uses a rubber roller (ink roller) to transfer the ink in the ink tank to the printing plate on the printing plate cylinder, so as to print the required text and other information on the surface of the carton. The current paper feeding methods mainly include chain feeding, push-back feeding and front edge vacuum suction feeding. Its characteristics are that the layout changes from simple to messy, and the processing accuracy is getting higher and higher. Usually, the accuracy of chain feeding processing is about ±1.5mm, while the accuracy of front edge vacuum adsorption can reach ±0.5mm. Of course, this is different. The value of equipment is also different.
