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.
Dots per inch. A close-up of the dots produced by an inkjet printer at draft quality. Actual size is approximately 1⁄4 by 1⁄4 inch (6 by 6 mm). Individual coloured droplets of ink are visible; this sample is about 150 DPI. Dots per inch ( DPI, or dpi[ 1]) is a measure of spatial printing, video or image scanner dot density, in particular ...
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 ...

A Polygraph is a duplicating device that produces a copy of a piece of writing simultaneously with the creation of the original, using pens and ink. Patented by John Isaac Hawkins on May 17, 1803, it was most famously used by the third U.S. president, Thomas Jefferson, who acquired his first polygraph in 1804 and later suggested improvements to ...
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.
Inkjet photo paper. Photo paper is inkjet paper specifically for printing photographs. It is a bright white due to bleaching or pigments such as titanium dioxide, and has been coated with a highly absorbent material that limits diffusion of the ink. Highly refined clay is a common coating to prevent ink spread.
