Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.A blade or squeegee is moved across the screen in a "flood stroke" 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.
For small-format printing, inkjet has also become the dominant technology, though special dye-sublimation transfer laser printers are also available. [6] In order to transfer the image from the paper to the substrate, it requires a heat press machine process that is a combination of time, temperature, and pressure.
A heat press is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics , specially designed presses can also be used to imprint designs on mugs, plates, jigsaw puzzles, caps, and ...
Thermal-transfer printing is done by melting wax within the print heads of a specialized printer. The thermal-transfer print process utilises three main components: a non-movable print head, a carbon ribbon (the ink) and a substrate to be printed, which would typically be paper, synthetics, card or textile materials.
Some cold-set web presses can be fitted with heat dryers, or ultraviolet lamps (for use with UV-curing inks), thus enabling a newspaper press to print color pages heat-set and black & white pages cold-set. Web offset presses are beneficial in long run printing jobs, typically press runs that exceed 10,000 or 20,000 impressions.
The essential tools required are a squeegee, a mesh fabric, a frame, and a stencil. Unlike many other printmaking processes, a printing press is not required, as screen printing is essentially stencil printing. Screen printing may be adapted to printing on a variety of materials, from paper, cloth, and canvas to rubber, glass, and metal.
Example of thermographic printing. The uneven quality of the text is a result of the process and easily differentiates thermographic printing from engraving Thermographic printing refers to two types of printing , both of which rely on heat to create the letters or images on a sheet of paper.
Shortly, the company evolved into one of the largest screen printed resort and licensed apparel companies in the United States. The company now (2018) runs automatic Screen Print presses and produces up to 10,000 to 20,000 T-shirts each day. In the 1960s, the ringer T-shirt appeared and became a staple fashion for youth and rock-n-rollers.
