The Rasterbator is an online tool for generating halftone images from uploaded image files. This technique is used in commerical printing to create large scale images that are seen from afar, such as billboards and banners. In the case of the rasterbator it is able to convert these large images into a series of standard A4 pages so that they can be printed on a standard printer and reassembled to create a larger final print.

The pdf’s that the rasterbator generates also contain vector information that can be opened in illustrator. A gallery of printed images is available here and here.
