4. Processing before printing
Similar to the dyeing process, the fabric must be pre-treated before printing to obtain good wettability so that the color paste enters the fiber evenly. Plastic fabrics such as polyester sometimes need to be heat-shaped to reduce shrinkage and deformation during the printing process.
5. the printing method
