PINGPONG#6: the birth of an image
Summer ping-pong: each week, a treasure from our collections will face a work from the “icons by Susan Kare” exhibition, according to a specific theme!
The matrix
Did you know? The mould is the origin of printing. It’s the wood or copper engraved block on which ink is applied before printing. If the text disappeared of the block with the apparition of the mobile character, the image kept being printed this way until the lithography appeared at the turn in the 19th century.
The grid
To create her icons, Susan Kare used a bitmap grid made of many points of several colours that give form to an image. This grid is the matrix, and the image appearing from it is a « raster graphic ». When she started, Susan Kare used a 32x32 monochrome grid so 1024 pixels. Thanks to this matrix, she created some of her most famous icons ! It is also the size she prefers for portraiture as the famous portrait of Steve Jobs.
