reticulation
n.
An irregular pattern of lines.
PhotographyAn image characterized by an irregular pattern of lines in the emulsion formed during processing.
Notes
Reticulation2 is generally considered a defect, usually resulting from immersing film in solutions with different temperatures. The emulsion absorbs an unusual amount of water and does not retain its original, smooth surface after drying. However, reticulation may be used for artistic effect. The collotype process uses a reticulated colloid (gelatin or albumen) to form an image on a printing plate.
