Li tho printing, also referred to as lithography or oceanography is a type of printing that works on the basic concept that water and oil are Canada WhatsApp Number List miscible liquids. Here, the areas of image and non-image are on a single surface unlike in the case of intaglio and relief printing where they are on different levels, the image area being higher than the base Canada WhatsApp Number List non-image area. Lithography is considered as a traditional Canada WhatsApp Number List and definitive means of approaching high-capacity printing.
The high-quality results of lithe printing stem from a unique and complex operational process that begins with the coating of a light-sensitive Canada WhatsApp Number List emulsion coating on the printing plate. Transferring the image onto the plate is done in several ways. One technique is placing the film on the plate and then exposing it to light. The second Canada WhatsApp Number List way of doing this is using machines that expose the plate using lasers. In either case, there takes place a detailed formation of the negative of the picture that needs to be printed. Next, the emulsion that was coated in the first step is released and thus a positive Canada WhatsApp Number List image of the picture gets imprinted.
The unexposed areas are then removed on treatment with chemicals. Li tho printing is the most nonrestrictive and versatile Canada WhatsApp Number List process of printing today. It is the first choice among artists as it allows them the freedom to use any kind of medium- pens, oils, pencils, crayons, etc and be able to create artwork Canada WhatsApp Number List having the same impact. Commercially, the application of lithography works differently where instead of a stone plate, metal plates are used. The mounting of metal plates on lithe presses is Canada WhatsApp Number List relatively much easier and this factor has made lithe printing viable for mass production.
