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 to fill the open mesh apertures with ink, and a reverse stroke then causes the screen to touch the substrate momentarily along a ...
Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. [ 1] The verb form of sublimation is sublime, or less preferably, sublimate. [ 2] Sublimate also refers to the product obtained by sublimation. [ 2][ 3] The point at which sublimation occurs rapidly (for further ...
UV curing is adaptable to printing, coating, decorating, stereolithography, and in the assembly of a variety of products and materials. UV curing is a low-temperature, high speed, and solventless process as curing occurs via polymerization. [2] Originally introduced in the 1960s, this technology has streamlined and increased automation in many ...
Printed electronics is a set of printing methods used to create electrical devices on various substrates. Printing typically uses common printing equipment suitable for defining patterns on material, such as screen printing, flexography, gravure, offset lithography, and inkjet. By electronic-industry standards, these are low-cost processes.
Photographic processing. Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.
Screen-printed electrodes (SPEs) are electrochemical measurement devices that are manufactured by printing different types of ink on plastic or ceramic substrates, allowing quick in-situ analysis with high reproducibility, sensitivity and accuracy. The composition of the different inks ( carbon, silver, gold, platinum) used in the manufacture ...
t. e. Lithography (from Ancient Greek λίθος (líthos) 'stone' and γράφω (gráphō) 'to write') [1] is a planographic method of printing originally based on the immiscibility of oil and water. [2] The printing is from a stone ( lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author ...
Photosensitizers are light absorbers that alter the course of a photochemical reaction. They usually are catalysts. [1] They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state ...
