Scope note
A type of photolithography in which the printing plate is prepared using a bichromate process. Unhardened gelatin areas hold water and thus resist greasy ink; hardened areas accept ink and hold it in the characteristic wormlike pattern of cracks.
English
Fotolitograafia liik, milles trükiplaat valmistatakse bikromaatprotsessi teel. Trükiplaadi kõvastumata želatiinist piirkonnad sisaldavad vett ning ei seo seetõttu värvainet; kõvastunud piirkonnad seovad värvainet ning tekib iseloomulik ussilik muster.
