A screen printing incorporates multiple mesh frames, inks, and a material to place the print upon. First, an image to screen print is created or chosen. Once this image is chosen, the different colors are defined. For each color, a new screen must be used.
To begin, once the image and colors are defined, the different layers must be introduced onto the print surface through specially treated mesh screens that allow the transfer of the parts of the print design. Each color gets its own layer. Screeners/printers must also be aware of how to layer colors: some colors must be laid over others so that they show up.
Once the order of color for the screens is defined, the screener then places the material to be printed in position for the first the first screen. The screener then places the squeegee (a spreader) behind the ink reservoir and drags the ink over the screen, laying ink upon the material below. Once this layer dries, the screener repeats the process with other inks through fresh screens.
This process can also be completed on a rotary screen. For this, the cylinder is treated in the same fashion as a mesh screen. The cylinder is inked and it rolls over the material to be printed. Cylinders can be changed or cleaned and re-inked.
A screen print is when someone creates a printed piece of work by pushing ink through a screen. It uses an outlining technique commonly referred to as a stencil. The stencil is attached onto a screen which can be lifted up and down to put in new pieces or paper or whatever medium is being used. Once positioned, the screen is then placed downwards onto the paper and a special squeegee is used to push ink from the top of the screen onto the paper underneath the screen.
