Wiki Explains Litho Printing

Lithography uses simple chemical processes to create an image. For instance, the positive part of an image is a water-repelling ("hydrophobic") substance, while the negative image would be water-retaining ("hydrophilic"). Thus, when the plate is introduced to a compatible printing ink and water mixture, the ink will adhere to the positive image and the water will clean the negative image. This allows a flat print plate to be used, enabling much longer and more detailed print runs than the older physical methods of printing (e.g., intaglio printing, letterpress printing). Lithography was invented by Alois Senefelder in Bohemia in 1796. In the early days of lithogra. To read more click on the following link.

Litho Printing

The most modern applications of litho printing now take advantages of photographic processes, with the plate being a photographic negative of the final desired image. The plate is roughened and covered with a photosensitive media, following which it is exposed to UV light. Despite its invention as far back as 1796, litho printing is the most widely used means of printing on mass.

Modern Litho printing

Modern litho printing involves creating an image in a polymer coating which is then applied to an aluminium plate. The surface of the plate is roughened and manipulated chemically so that some regions are hydrophilic and act to accept water, and repel ink, while others are hydrophobic and act to repel water and accept ink. As a consequence, printing can be done directly from the aluminium plate, resulting in a reversion of the image, or the image can be transferred onto a sheet of rubber.

The main process of litho printing is the production of hydrophobic and hydrophilic regions on the stone or aluminium plate. The terms hydrophobic and hydrophilic are chemical terms, literally meaning ‘water loving’ and ‘water hating’ respectively. Unlike processes of etching, or engraving, the plate does not act as a ‘stamp’ with raised sections. Instead, the entire plate is at the same level, with the ink adhering or not based on chemical reactions. To find out more about our litho printing services visit us at www.pepper.co.uk

Litho Printing

Lithoprinting, also called lithography is a method of printing that uses a completely smooth surface, traditionally stone or a metal plate. Litho printing was invented in 1796, and it was initially developed as a method of producing theatrical works at low cost.
