Umgaqo-nkqubo we-etching: ukudibanisa kunokuthi kube yi-photochemical etching, ngokwenza i-plate ye-exposure kunye nophuhliso, ifilimu ekhuselayo yendawo yokutshiza iya kususwa, kwaye inxalenye yensimbi engenasici ekhutshwe kwifilimu ekhuselayo iya kuqhagamshelana nesisombululo seekhemikhali ezisetyenziselwa ukubethelwa, ukwenzela ukuba kufezekiswe umphumo wokuchithwa kunye nokubola, ukwenza i-concave kunye ne-convex effect okanye i-molding effect.

Etching inkqubo yokuhamba:

Indlela yokuvezwa: ukuvulwa kwemathiriyeli → ukucocwa kwemathiriyeli → ukomisa → ukwalamisa → ukomisa ukuvezwa → ukuphuhlisa → ukomisa → ukuhombisa → ukuhluba

Ukuprintwa kwesikrini: izinto eziphathekayo - ipleyiti yokucoca - ukuprintwa kwesikrini - i-etching - ifilimu

Iinzuzo zokurhweba ziyabonakala. Iyakwazi ukwenza umatshini ofihlakeleyo kumphezulu wesinyithi, inika umphezulu wesinyithi iziphumo ezikhethekileyo. Kodwa i-drawback kuphela kukuba sixhalabile malunga nengxaki yesisombululo solu hlobo lolwelo oludlekayo alunamsebenzi kumzimba womntu okanye ubume bendalo buyingozi, kodwa ukwakheka okuncinci sele kutshilo, kunye nezinto kunye nokusetyenzwa kwentsimbi engatyiwayo emva kwenye inkqubo yasemva kokulungiswa, unyango lomphezulu wezinto ezinobungozi emzimbeni aluyiyo nayiphi na into enobungozi emzimbeni womntu ayihlali kuyo nayiphi na into enobungozi emzimbeni.
