Screen printing is a method of printing that uses a mesh to transfer ink onto fabric. The process involves placing a stencil onto the fabric printing hong kong and then pulling the stencil through a silk screen, which transfers ink through the holes in the stencil onto the material below. This technique also allows for multicolor prints because every color must be applied individually using its own screen.
Screen-printing is a printing technique that uses a mesh to transfer ink onto a substrate, except in areas made impermeable to the ink by a blocking stencil.
The screen used for screen printing is made of fine metal wire stretched over a wooden frame and coated with emulsion. To make a stencil, special screens are prepared by coating them with photopolymerizable emulsion and then exposing them to light through the image to be printed. The unexposed areas harden and can be washed away with water or solvent, leaving only the exposed polymer.
A blade or squeegee is moved across the screen to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a line of contact.
- The mesh is stretched across a frame (or the screen).
- Ink is applied to the mesh, and a squeegee or blade (a tool with a rubber blade on one side) passes over it to fill up each of the open mesh apertures.
- As you pull back from your substrate, that contact causes the screen to touch for just an instant. That brief moment of contact transfers ink from your screen onto your substrate.
The blade is lowered, allowing the ink to flow through the mesh and onto the substrate. As it passes through, the screen springs back up against a squeeze roll. This causes the ink to wet the substrate and be pulled out of the mesh apertures as the screen springs back after the blade has passed.
This occurs rapidly enough that most of your design will have been transferred before you can see what’s happening from all angles. However, if you try holding your hand over where you think they’re fabric printing while they pass by with their squeegee, you’ll feel how fast this actually happens.
