What is Screen Printing
Screen printing is printing techniques ideally suited wherever a high degree of coverage, precise detail and color intensity are required to obtain a brilliant, high-quality image. Scented coatings, thermo chromatic inks and glitters are just a few examples of screen print applications. Screen printing also enables Braille to be applied to any label and relief printing. Screen print is printing technique that uses a woven and non woven mesh to support an ink-blocking stencil. The attached forms open areas a of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp edged image onto a substrate
Rotary Screen Printing:
Some people think rotary screen print is flat printing process because the substrates are usually flat and decorated in a horizontal position. Rotary screen printing is also related with piece decorating applications where individual sheets of substrate are printed one by one, usually on semi and three-quarter-automatic flatbed presses that require manual loading or unloading. So far throughput continues to be limited because every sheet of substrate still must pause at each printing station to receive the icon. The good news is that you don’t have to sacrifice the remuneration of screen print to overcome the limits of flatbed printing technology. For many applications requiring competent, high volume, high quality printing and rotary screen print may be the best answer. In rotary printing the web movements at a constant speed between the screen and a steel impression roller immediately below the screen. As the web passes through the rotary unit the screen spin at a rate that identically matches the speed of substrate movement.
The squeegee on a rotary press is in a fixed position with its edge making contact with the inside surface of the screen accurately at the point where the screen, substrate, and impression roller come together.

Printing Techniques by Rotary Screen Print :
Therefore as the printing techniques using ink is squeeze by pressure from the inside of the cylindrical mesh by way of a rubber squeegee, it exits through the open mesh that was masked during the photo coverage. The printing techniques using ink used in this process are quite opaque and rich colors are achievable. It is important that the printing techniques using ink is fully dry before the paper reaches the next print station and ensuring no show through or smudging of the inks from the color underneath. It does have the benefit of being cheaper, due chiefly to it being a continuous print process and rotary screen print is applicable for tshirt, shirt design, relief printing and t shirt designs.
