What type of prints are characterized by white paper with dark print?

The type of prints characterized by white paper with dark print is known as diazo prints. Diazo printing is a process that uses a photosensitive chemical compound to create images on paper. In this method, when the paper is exposed to light, the chemical reaction occurs, resulting in dark images against a bright white background. This contrasts with other printing methods, where the backgrounds and the prints may differ in color or medium.

Blueprints, while they also involve a form of print, are traditionally blue in color, created using a different chemical method that produces blue lines on a white background. Photocopies typically maintain the tonal qualities of the original document, resulting in varying shades of gray rather than the distinct contrast seen in diazo prints. Negative prints, on the other hand, present an inverted color scheme where dark areas appear light and vice versa, which does not fit the description provided.
