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 ...
Screen-printed electrodes 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 of the electrode ...
Unlike in screen printing, the ink is stamped onto the printing medium, rather than being squeegeed across it. This method allows the user to apply different colors of ink in different areas of the screen to produce a multi-color printed image.
Printer tracking dots, also known as printer steganography, DocuColor tracking dots, yellow dots, secret dots, or a machine identification code ( MIC ), is a digital watermark which many color laser printers and copiers produce on every printed page that identifies the specific device that was used to print the document. Developed by Xerox and Canon in the mid-1980s, the existence of these ...
