Cuban born, Clatonia Joaquin Dorticus of Newton, New Jersey invented an improved photographic print and negative wash machine (see patent drawing). During the process of developing a photographic print or negative, the product is soaked in several chemical baths. The print wash neutralizes the chemicals in each bath process, so that the time the chemicals effect a print can be exactly controlled. Clatonia Joaquin Dorticus believed his method would eliminate over washing that could soften the photograph too much.
Clatonia Joaquin Dorticus also invented an improved machine for embossing photographs (see patent drawing left). His machine was designed to both/either mount or emboss a photographic print. Embossing is a method or raising parts of a photograph for a relief or 3D look.
Clatonia Joaquin Dorticus's other inventions included an applicator for applying color liquid dyes to shoes and heels, and a hose leek stop.
