Calcografía (intaglio)

Intaglio (pronounced in-TAL-yo) is a printmaking technique in which the image is incised into a surface. Normally, copper or zinc plates are used as a surface, and the incisions are created by etching, engraving, or some other method. To print an intaglio plate, the surface is covered in ink, and then rubbed vigorously with a special cloth or with newsprint to remove the ink from the surface, leaving it only in the incisions. A damp piece of paper is placed on top, and the plate and paper are run through a printing press that, through pressure, transfers the ink from the recesses of the plate to the paper.

Conocer la diferencia entre el medio-tono, semi-tono y el proceso de cuatro colores.

Left: Shows the half-tone dots when magnified. Right: shows how this would appear normally.

Half-tone : this simulates a continuous shade of an image by using equally spaced dots of different sizes. See the Wikipedia article on Halftone

Duo-tone image made up of blue and black

Duo-tone : is a Half-tone picture made up of two printed colors. See the Wikipedia article on Duotone. This seems to have become also a generic word for 'color separation' printing like the four color process below. Duo-tone would only be using TWO colors.

Four-color process : is the process of combining the four basic printing colors (cyan, magenta, yellow, black), to create a picture, image, or colors.
