Final answer:
The printed image left behind by the matrix in printmaking is called an impression. It is the result of transferring ink from the matrix to the paper using various printmaking techniques.
Step-by-step explanation:
When creating a print, the printed image left behind by the matrix is called a(n) impression. The process of printmaking includes various techniques such as Relief, Intaglio, and Planar printing, each having a different method of transferring the image from the matrix to paper. In all forms of printmaking, ink is applied onto the matrix, and then paper is pressed against it to create the impression. For instance, in Intaglio printing, ink is forced into incised lines on a metal plate, and then the plate is wiped clean, leaving ink only in the recesses, which prints onto the paper when pressed together.
