Black Test Prints is a systematic study of the color black through office printing technology. The investigation deconstructs printed black by questioning how colors are created digitally and creating formulas that explore alternate ways of producing printed black. The prints are produced not only through formulas but also through testing the limits of the office printing technology used to create them. In this study we look at the black and white laser printer, the color laser printer, and the color inkjet printer. The results are a reflection of the process of working like a machine while also taking ownership of the machine errors that results in poetic abstract compositions.
