Fault Analysis: Ink instability is a large, small, unstable, and difficult to control print. This is because the gap between the ink rollers is too large, causing the ink layer on the surface of the ink roller to be unstable, and the amount of ink supplied varies accordingly.
Remedy: Adjust the gap between each ink roller. Use a 0.15mm thick feeler gauge to adjust with a 2kg force. It should be noted that if the pressure adjustment between the ink rollers is too large, the frictional force will increase, and the heat generated at both ends of the ink roller will damage the ink roller; however, if the pressure is adjusted too small, the ink supply volume will be unstable and the printing cannot be performed properly. .

LED is favored by manufacturers because of its energy saving, small size, long life and safe DC voltage power supply. The ultra-thin LED copy table adopts the backlight technology of liquid crystal display. Produced, the light evenness is very good, enough to be comparable to the display. In addition, the panel material adopts reinforced safety optical glass with excellent hardness and light transmittance, which is scratch-resistant, aging-resistant, long-lived, and good evenness. It has also been popular with animation workers.
