Screen printing is a process that involves using a mesh and an ink-blocking stencil to print designs on a substrate. Easy to accomplish so much so that DIYers print out their own clothing, snowboards and decals, the process also finds its way into professional areas like circuit board printing, thick film technology, medical devices and product labels.
There are three screen printing presses most commonly used with rotary being the most popular.
Rotary screen printing
Rotary screen printing is a mechanized version of the manual process. Squeegee blades which are located inside hollow screen-mesh cylinders force ink on a wall covering or fabric which travels through a printing press. The process is ideal for achieving a rich look at a lower cost.
Flat-bed printing makes use of a flat screen rather than a cylinder to deposit ink on a substrate. The screen is placed over the material and a squeegee is pressed against the mesh to ink the image area. Once done, the screen is removed and the substrate is dried.
A cylinder press is primarily used to print images or text on round objects. They could be cups, mugs or other circular objects that cannot be printed on using the other two presses.
