Know Your Printmaking Processes
If you've ever thought about purchasing prints or even making them yourself, this post is for you!
We've put together a primer for those interested in learning more about the different forms of traditional printmaking. Instructional videos from the Edinburgh Printmakers are shared to demonstrate each process (because who doesn't want dulcet Scottish tones explaining how things are made?) and credit also to Crown Point Press - their glossary page was very helpful in pulling this info together.
The most common method of commercial printing (typically referred to as "offset lithography" in commercial contexts), also used for fine art printing. It is a method of printing based on the repelling tendencies of oil and water. The area that prints (the positive space) is created with oily material, and the non-printing area (the negative space) is differentiated by a chemical treatment that makes it receptive to water. Ink is rolled over the entire plate, which is sponged with water before each print. The oily ink sticks only to the positive areas that have been created by the oily material.
A stencil method of print making in which a design is imposed on a stretched screen of polyester with blank areas coated with an impermeable emulsion. Ink is forced into the mesh openings by a squeegee and transferred onto the printing surface (paper, fabric) during the squeegee stroke. As the screen rebounds away from the paper or textile the ink remains on its surface. It is also known as silk-screen, screen, serigraphy, and serigraph printing. One color is printed at a time, so several screens can be used to produce a multi-colored image or design.
This is the process we use to create all of our limited edition prints!
A type of "intaglio" print, a term that also includes engravings and dry point prints. In general, etching processes involve coating the plate with an acid-resistant ground, removing the ground in the image areas, then submerging the plate in a bath of diluted acid to create areas of differing depth that the ink can sit within.
You can easily spot an intaglio prints as they are the only process that embeds in a paper sheet and physically embosses it. You will see embossed plate edges clearly around the image area of an intaglio print; the image itself also is embossed.
Relief printing, the oldest print process, encompasses woodcut, linocut, hand-set type, rubber stamps, and related processes like potato prints. The plate or block is incised, but the ink is applied to the top surface rather than to the incisions as in intaglio. Intaglio plates can be printed in relief, and sometimes relief and intaglio inkings are combined.
You'll notice we haven't covered digital printing processes in this round-up and that is because we want to do a separate post explaining all of the unique terms and processes that digital printing emcompasses. Stay tuned!
