Images are created by blocking parts of the screen with stencils created by hand-drawn or photographic techniques. Ink is forced through the open areas of the screen onto paper or fabric. Lithography Lithography is a process based on the chemical principle that oil and water do not mix. Images are drawn on limestone or metal plates with crayons and inks which contain wax or oil. The stone or plate is wet before each inking with a roller, so the oil-base ink will adhere only to the image areas.
Paper is pressed against the surface with a bar or roller press.
Computer prints Computer Prints take advantage of innovative new technology including laser and inkjet printers. A digital document tells the computer printer which colors to spray onto the paper for each dot. Images can be drawn on an electronic tablet, scanned from drawings or photographs, or created mathematically and altered with software programs before printing. Here are examples of terms from the complete glossary that we are working on. Lithotint A lithographic technique in which lithographic ink is diluted with varying amounts of water before it is painted onto the stone or plate to create the image.
