I've been doing partial halftoning of different aspects of a design in order to fade it into the shirt color... it requires a process that you extract the colors of the artwork and then process to halftones and then knock it out from the image but also reveal those colors in the image so it doesn't cut back too much. Using larger halftone dots usually works better until you can figure out the smallest ones you can do that hold well. I've got a lot of videos on my youtube channel that go into working with color and making parts of images halftones, lots of free actions and tools for photoshop that do that stuff, but I only recently made a DTF-specific action set that will automate the steps for you... if you just want black removed to halftones for a black shirt, white, any colored shirt etc. It's not that difficult to do manually but it becomes tedious to go through the same steps every time so that is why I usually make actions for these kind of things. As long as you keep it so there are only transparent pixels and non-transparent pixels and nothing fading between that, keep it higher resolution or just don't change it or let it get anti-aliased/resized/blurred... then it prints amazingly and it really helps the entire look and feel of the process. For me I don't do DTF without doing some form of shirt-color-removal to halftones process unless it just doesn't need it. But even fading to white on a white shirt can work great to save a lot of ink, fading to black and don't use any black or print all that large area of the image, no big squares or sheets of ink/powder going down, and especially cool when you have artwork that fades into a specific color background that would be the shirt color, then you can knock that out too and not have to try and match the color, just let the halftones fade the artwork into the shirt. It can also be used for graphics effects or just give it a style, use custom patterns like different shapes or textures, usually round dots at 30 LPI, 45 degree angle is a good start, 600 dpi to keep them clean. DTF is really one of the best processes once you reach that level of doing the halftoning stuff.
