Refurbishing Second-hand Thermal Sublimation Equipment: Open Call for Practical Tips on Adapting Old Print Heads to New Coating Materials

[Koalaylc]

Our company has recently tested a new type of sublimation sheet 9 with a polycarbonate substrate + polyurethane coating, which is claimed to improve color reproduction for semi-transparent printing. However, we found significant differences in equipment compatibility (for example, Epson's older print heads tend to clog easily). Have other companies encountered similar issues? Are there any low-cost adaptation solutions or alternative materials recommended? We welcome you to share your technical challenges and practical experiences!
