    Can you guys please help me with my problem. I am searching web for 2 months and no luck. I have build Direct to garment printer using Epson 2200. I would like to print on dark garment. In order to do this I would have to print white underbase of the image first. Since epson 2200 has 7 inks set, I am planning to use Light black, Light magenta and Light cyan channels for white ink. My problem is how to trick printer to print image using just those 3 channels. I have one idea and I dont know if this will work. I will open image in Photoshop, than I will change color mode to grayscale, than to duotone mode. When duotone mode wndow pups up I will change to tritone and I will change color values of each of 3 available swatches to Lb, Lc and Lm RGB values. Finally I will switch mode to RGB and send it to printer via Gutenprint plugin. Do you think this will work?
    Also, can you please tell me how to set-up gutenprint output to put as much ink as posible using just those 3 channels. I would really apreciatte your help and this would be huge help for DTG DIY comunity since prices for rip software that work with DTG printers are outrages. Thanks in advance
