pointillistic silkscreen using a line printer

From 1970 to 1974, the display screens were not available. It was necessary to find a way to view the image which had been calculated, a task complicated by our choice to work with colors . We have used all that we could find, since the paper of the printer, followed by punched cards and finally by a plotting table to produce serigraphs.

During the following years (75-80) we began to explore a first display screen "the Colorix " built in our university.
