What is printing?
Introduction to Printmaking
Printmaking is an art form that involves creating images using a matrix or surface from which prints are produced. This ancient technique has been used for centuries and continues to be popular among artists today.
The Process of Printmaking
There are various methods in printmaking, but the fundamental process typically involves several steps: creating an image on a plate or block, transferring that image onto paper using ink, and finally pressing the paper to transfer the ink from the matrix. The resulting prints can be unique or multiple copies.
Different Techniques
- Lithography: Uses stone plates and oil-based inks; images are drawn directly onto the smooth surface of the stone.
- Intaglio: Involves etching or engraving into a metal plate, then using acid to cut into the lines; ink is applied to the incised areas and transferred to paper under pressure.
- Screen Printing (Silk Screen): Involves stenciling an image onto a mesh screen with ink, which is then forced through the openings of the mesh onto the substrate below.
- Woodcut and Linocut: These are relief printing techniques where images are carved into a surface (wood or linoleum) and ink is applied to the raised areas; paper is then pressed against this to transfer the image.
Applications in Commercial Printing
In the commercial world, printmaking techniques are used for creating promotional materials, books, newspapers, periodicals, and other printed products. Lithographic printing, in particular, is widely utilized due to its high volume capabilities and ability to produce sharp, clean images.

Lithographic Printing: An Overview
Lithography, often abbreviated as "litho," is a method of printing that uses a planographic process. This means it relies on the physical properties of the printing surface rather than raised type or plates.
History and Principles
The term 'lithography' was coined by its inventor, Alois Senefelder, in 1796. The principle behind lithography is the repulsion of oil and water. Images are drawn on a flat limestone (or aluminum) surface with a greasy substance called 'damping ink.' Water is then applied to the stone, which repels the water and adheres only to the inked areas.
Printing Process
In commercial settings, lithographic printing is widely used for high-quality prints such as magazines, books, newspapers, and packaging. The process involves several steps including image preparation, stone (or plate) creation, inking, dampening, and finally, pressing the paper to transfer the ink onto it.
Applications
- Magazines and Periodicals: Lithography is ideal for color printing due to its high resolution.
- Newspapers: The quick turnaround times and large print runs are well-suited for this application.
- Books: High-quality text and images are achieved through lithographic printing.
Lithography is a cornerstone of the publishing industry in the USA, offering versatility, high quality, and cost-effectiveness for various commercial printing needs.
