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.
Plastisols are the most commonly used inks for printing designs onto garments, and are particularly useful for printing opaque graphics on dark fabrics. Plastisol inks are not water-soluble. The ink is composed of PVC particles suspended in a plasticizing emulsion, and will not dry if left in the screen for extended periods. Garments don't need ...
The problem can occur with most types of printing. Anti-set-off spray powder is generally made from natural starches from plants and vegetables. There remains a demand for soluble powders (sometimes known as vanished powders) based on natural sugars [ 1 ] which are often used when the final printed sheet is to be varnished.
Thinner traps are less visible. Therefore, the trap width is set to a strict minimum, dictated by the maximum amount of misregistration of the entire workflow up to the press. When printing at 150 lpi, traps are usually between 1/150 and 1/300 inch (0.48 pt and 0.24 pt, 0.16 mm and 0.08 mm). These values are usually multiplied by 1.5 or 2 when ...
The most common form of commercial T-shirt decoration is screen printing. In screen printing, a design is separated into individual colors. Plastisol or water based inks are applied to the shirt through mesh screens partially coated with an emulsion which limits the areas where ink is deposited. In most commercial T-shirt printing, a limited ...

Screen-printing is the process of transferring an ink through a patterned woven mesh screen or stencil using a squeegee. [8] For improving accuracy, increasing integration density and improving line and space accuracy of traditional screen-printing photoimageable thick-film technology has been developed. Use of these materials however changes ...
Anything that is produced using traditional printing techniques is a candidate for ink jet material deposition. In addition, the precision available with ink jet technology may be required for some industrial applications. Examples include: Organic light-emitting diode display production.
