Intaglio was a very common method of image reproduction between 1500 & 1900 and the resulting images were incredibly precise.
It’s quite simple;
- Cut into a hard surface (such as a copper plate)
- Cover it in ink, wipe off the excess.
- Press paper or fabric onto the surface, remove it and the image will have been transferred. Force from pressing causes ink to transfer from the grooves of the engraving onto the print medium.
Bank notes have illustrations which were originally copper plate engravings (intaglio).
Woodblock prints are in relief. Relief printing was an alternate and common method where ink is applied to the surface details of an engraving but not to the grooves or recesses. The image is transferred by pressing paper or fabric onto the engraving. Or in the case of a stamp, the engraving is placed onto ink, then onto paper - transferring the image.
You can make a relief print using a potato and red wine. Cut the potato in half,prints at home with a knife carve out a chevron into the potatoyour shoes when you track mud from outside, creating foot prints. Dip the potato into the wine then press
Relief printing is more primitive in that it requires less force to transfer the potato onto your shirtimage than intaglio and can be reproduced by hand.
