The Time Print Machine by designer Paul Ferragut was created by using felt-tip pens that connect to a device controlled by custom hardware that prints out pointillist images. The variation between depth and shading comes from the reaction of the pen and its ability to 'bleed' through the paper. The longer a dot is created, the more ink there is and therefore the darker the pixel ends up being. Although the machine is doing most of the creative work, the real artistry is the Time Print Machine itself.
Ferragut could potentially create any image with this machine but so far the artist has chosen to stick to portraits. At the moment the printing process is open to experimentation and can only at the moment print Yellow, Magenta, Cyan and Black. Each painting took roughly ten minutes to complete using the printing machine.
