Collotype and Photo-lithography

"Collotype and Photo-lithography" by Julius Schnauss is a late 19th-century exploration of collotype printing and photo-lithography techniques. This scientific book is aimed at photography and printing professionals and enthusiasts, providing a detailed understanding of the materials, methods, and uses of these photographic techniques. The narrative starts by setting the stage for an investigation into the chemical processes behind collotype and photo-lithography, beginning with how bichromate of potassium’s sensitivity to light was observed by Mungo Ponton, Fox-Talbot, and other early pioneers. Schnauss communicates how these early discoveries led to the development of innovative printing processes, outlining the significant contributions of later researchers. The book's first chapters discuss the chemical interactions, material preparation, and apparatus involved, which provides a foundational framework for readers to understand the ins and outs of collotype printing techniques.
