Screen Printing
A printing technique that allows obtaining prints by pushing ink through the printing plate. A mesh screen is used as a printing plate. It is made of natural silk, synthetic fabric or metal threads. Spacing elements are covered by a layer that does not let the printing ink through. Printing elements are uncovered. During the printing process, a thin layer of ink is evenly pushed through the mesh screen by a rubber or polymer squeegee onto the print-receiving material. This technique is used for printing images which do not contain thin lines or small details.
Special features of the print:
- no pressure and substrate deformation;
- thick ink layer (the layer thickness corresponds to the thickness of the printing plate);
- zigzag or uneven edges of the image.
