Definitions for "Planographic"
One of the four basic printmaking families, this refers to prints made from a smooth plane. This term is seldom used when naming printmaking techniques, but this is the family of two very common forms of printmaking: lithography and monotype.
A method for printing ink onto paper, where the image sits on the same surface as the printing plate. The image area is greased to attract ink, while the rest of the plate attracts water and repels ink. As the paper is pressed onto the flat surface of the plate, it picks up ink from the greasy image areas and a small bit of water from blank areas. This is the printing process used in lithography and offset lithography.
Image and non-image areas are printed on the same plate. Image areas receive ink. Non-image areas repel ink.
