Photo-Lithography

"Photo-Lithography" by Georg Fritz is a scientific guide from the 1800s, acting as a detailed manual for the photo-lithographic process, a blend of photography and lithography critical to graphic arts. Penned by a Printing Works vice-director, the book shares practical insights to promote the adoption of this method for making printing plates, highlighting its ability to create color plates with minimal manual work. Beginning with a preface and introduction, the author explains photo-lithography's role in modern printing, discussing the basics of lithography, chemical interactions, and materials like litho stones and zinc plates for producing prints. Fritz stresses the need for light-sensitive materials and preparing negative images to make this reproduction successful, setting the stage for the techniques covered.
