The chromatic aberration problems caused by DTF Printer due to operation problems are as follows:
1. The ink supply system of PET Film dtf is unstable, especially the liquid level of the ink cartridge, which greatly affects the ink supply power of the print head and directly affects the printing effect. When the liquid level is high, the color is darker than when the liquid level is low, which leads to the color difference of the picture.
2. The working voltage of the T-shirt printer print head is unstable or the voltage changes during the printing process. The size of the print head’s operating voltage directly affects the ejection force of ink droplets, especially the piezoelectric print head. From the perspective of the overall visual effect, There will be different shades and different clarity effects. Therefore, before printing out, the print head voltage should be set to normal, generally adjusted in the software, and the input terminal of the printer should be connected with a voltage stabilizing device.
3. The negative pressure is unstable. For printers that use the principle of negative pressure to supply ink, the negative pressure is unstable, which also directly affects the ink supply pressure of the print head, which in turn affects the inkjet effect of the print head.
4. Sticky head, caused by frequent cleaning of the print head. Due to faults such as sticky head and ink breakage, the print head needs to be cleaned frequently, which will cause color difference on the screen and discontinuous picture effect. Because there will be a big difference in the effect before and after cleaning the print head. We suggest that before the white ink heat press printing is printed, check the working status of the white ink heat press printing machine to ensure that it is correct before production. Secondly, when selecting ink, it is necessary to purchase ink with good quality and guaranteed quality.
