ABOUT BIG CAT
Dye-sublimation is a process that uses heat to allow the solid pigments to vaporize and then the colors are transferred to the intended substrate.
PBT (Polybutylene terephthalate) is used as the raw material for injection. The final product gains the resistance to high temperature, corrosion and oxidation from the PBT plastic.
Disperse ink is digitally sprayed through piezoelectric nozzles onto coated papers composed of silica and other composites.
Treating the printed papers with high heat and high pressure allows the solid pigment to sublimate into air molecules. The pigment is then transferred and dyed into the keycaps.
Solid pigment molecules penetrate into the product as deep as 0.15mm, making the dye-subbed image wear resistant.
No platemaking required for changing color, legend or image, lowering the cost of customization.
Product undergoes alcohol, disinfectant, artificial sweat, ultraviolet, salt spray and other tests, demonstrating high weather resistance.
