RIP0.3 version, you can change the ink channel according to your custom requirements). If the color (CMYK) nozzle is clogged, the custom channel setting function allows channel replacement. For example, if yellow is blocked, use the white channel and use yellow ink in that channel and close the original yellow channel. A simpler example is to replace the white ink cartridge with the yellow ink cartridge in the working channel and make this setting in the setup menu. This function is very useful in the system of UV, DTF, DTG printers. Even if the channel is blocked, you can continue to use the print head. There is no need to replace the new print head immediately, because you have 2 or 4 white in the channel as Substitute.
