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 ...
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 line of contact.
The Print Gocco process was a variant of screen printing; Print Gocco housed both the screen-making and screen-printing elements within one compact footprint with a hinged plastic frame. The materials included proprietary blank screens, consisting of thin layer of thermoplastic bonded to a mesh, held in a cardboard frame and covered with ...
Conductive ink is an ink that results in a printed object which conducts electricity. It is typically created by infusing graphite or other conductive materials into ink. [ 1] There has been a growing interest in replacing metallic materials with nanomaterials due to the emergence of nanotechnology. Among other nanomaterials, graphene, and ...
A school newspaper published using a ditto machine in 1978. A hand-cranked spirit duplicator from the 1960s. The duplicator uses two-ply "spirit masters", also called "master sheets". The first sheet can be typed, drawn, or written upon. The second sheet is coated with a layer of wax that had been impregnated with one of a variety of colorants.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [ 1] Inkjet printers were the most commonly used type of printer in 2008, [ 2] and range from small inexpensive consumer models to expensive professional machines.
Thermochromic ink (also called thermochromatic ink) is a type of dye that changes color in response to a change in temperature. [1] [2] [3] It was first used in the 1970s in novelty toys like mood rings, but has found some practical uses in things such as thermometers, product packaging, and pens. [4] The ink has also found applications within ...
Offset printing is a common printing technique in which the inked image is transferred (or "offset") from a plate to a rubber blanket and then to the printing surface. When used in combination with the lithographic process, which is based on the repulsion of oil and water, the offset technique employs a flat ( planographic) image carrier.
