DTG Distributor, who also sells the proper inks for your system. In regards to flushing solution/cleaning solution the solutions sold by the ink resellers are generally manufactured by the ink companies with the proper chemical components to break down the inks - usually some sort of detergent agent, a surfactant, a whetting agent and purified/distilled water. If you are concerned about the cost of the commercial formulas, try cutting them with distilled water, this will be helpful if you are using it to flush lines, and is a way to quickly cut costs.
