Collotype
A photomechanical printing method developed by Alphonse Poitevin in the 1850s and made practical by Joseph Albert in the 1860s and 1870s. It printed continuous tones from a gelatin plate with no dot screen.

Why it happens
A bichromated gelatin plate hardens in light and takes ink in proportion to exposure, so tone transfers without a halftone screen, only a faint natural wrinkle pattern.
