Picture of the day

Intaglio is a printing and printmaking technique in which an image is incised into a surface, with the resulting incised lines and sunken areas holding ink. It is the direct opposite of relief printing, in which the parts of the matrix that make the image project from the main surface. The intaglio process probably originated in Germany in the 15th century, and came to be used for many mass-printed materials. Nowadays, intaglio engraving is mostly used for paper currency, passports, and occasionally high-value postage stamps.
