If the ink is water-based and the powder is acting as a binder for the pigment, I'd just replace the CMYK DTG inks
with standard pigmented water-based inks , which have much lower amount of resins and are much less likely to cause clogging problems even if the printer is not used for a longer time. In general, the pigments would be the same colour indexes, except maybe for the yellow, which for DTG is standardly P.Y.155. Cyan would in both cases be P.B.15:3, magenta P.R.122 and black is P.B.7. However, white would still be the one for DTG as P.W.6 (TiO2 ), which has a very high density of 4.2 g/cm3, is more stable in this formulation. Cleaning fluid is based on deionized water and a selection of polyols, some amines and surfactants.
