Process
The process of screen printing involves creating a stencil, or screen, using a mesh fabric stretched over a frame. The design is transferred onto the screen by blocking certain areas with a stencil or using photosensitive emulsion. Ink is then forced through the open areas of the screen onto the substrate using a squeegee. This method allows for precise and vibrant designs, especially when printing on dark or colored fabrics.
On the other hand, sublimation is a digital printing technique that uses heat and pressure to transfer dye onto the fabric. The design is first printed onto a special sublimation paper using sublimation ink. Then, the paper is placed on the fabric, and both are subjected to heat and pressure in a heat press machine. The ink vaporizes and permeates the fabric, resulting in a permanent, full-color design that becomes part of the fabric itself.
The Equipment: Screen printing requires a screen, a squeegee, ink, and a printing press. Sublimation, on the other hand, requires a sublimation printer, sublimation ink, transfer paper, and a heat press machine.
Complexity: Screen printing involves multiple steps, including screen preparation, stencil creation, and ink application. Sublimation, on the other hand, is a relatively straightforward process that requires proper printing settings and heat application.
