In 1860 the phototransfer process was patented, enabling a photographic image on sensitized paper to be inked and transferred to the printing surface. Techniques developed in the 20th century varied the process considerably, though many artists continue to prefer the time-honoured method.

Each process has its own benefits and downsides, and works best for specific purposes. 74 In the flow-lithography-based microfluidics approach, photocurable chemicals are introduced into a microfluidic channel and then they are selectively exposed in situ using a focused UV light shaded by a photomask. First, the design or image for the lithograph is drawn directly onto the stone slab or metal plate using an oil-based crayon or ink. But how does this ‘chemical’ printing process work? What is Lithography? Offset lithography, the most commonly used printing process, and detail the three production steps: pre-press, press run and bindery. The offset image is then run quickly onto a print spool, transferred via a conveyer belt underneath the rollers. When the plate is inked, only this image part holds ink. That inked image is subsequently transferred (or offset) from the plate to a rubber blanket and then to the printing surface. What is Litho Printing? Have you ever wondered what the true difference between a lithograph and print is? lithography: A printing process in which the image to be printed is rendered on a flat surface, as on sheet zinc or aluminum, and treated to retain ink while the nonimage areas are treated to repel ink.
