2. Rotogravure - Wikipedia

   en.wikipedia.org/wiki/Rotogravure

   Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press. Once a staple of newspaper photo features, the rotogravure process is ...

3. Photogravure - Wikipedia

   en.wikipedia.org/wiki/Photogravure

   Photogravure. Photogravure (in French héliogravure) is a process for printing photographs, also sometimes used for reproductive intaglio printmaking. It is a photo-mechanical process whereby a copper plate is grained (adding a pattern to the plate) and then coated with a light-sensitive gelatin tissue which had been exposed to a film positive ...

4. Conductive ink - Wikipedia

   en.wikipedia.org/wiki/Conductive_ink

   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 ...

5. CMYK color model - Wikipedia

   en.wikipedia.org/wiki/CMYK_color_model

   CMYK color model. Color printing typically uses ink of four colors: cyan, magenta, yellow, and black. When subtractive CMY inks are combined at full strength, pairwise combinations are red, green, and blue. Combining all three gives an imperfect black color. What appears as cerulean ( ) in the top image is actually a blend of cyan, magenta ...

6. Printed electronics - Wikipedia

   en.wikipedia.org/wiki/Printed_electronics

   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.

7. Rotary printing press - Wikipedia

   en.wikipedia.org/wiki/Rotary_printing_press

   William Nicholson filed a 1790 patent for a rotary press. The rotary press itself is an evolution of the cylinder press, also patented by William Nicholson, invented by Beaucher of France in the 1780s and by Friedrich Koenig in the early 19th century. [1][2] Rotary drum printing was invented by Josiah Warren in 1832, [3] whose design was later ...
