An Albertype is a picture printed from a kind of gelatine-coated plate produced by means of a photographic negative.[1] The process was invented by Josef Albert in 1869.[2][3]

The technique is similar to collotype, but substitutes the gel plate for the lithographic stone used in collotype.[2] Heliotype, invented in 1871 by Edwards, is another similar process.[2]
