Kunezindlela eziningi zokuncishiswa komhlaba kwangaphambi kokuphrinta kweumshini wokuphrinta amafilimu wepulasitiki, okuvame ukuhlukaniswa ngendlela yokwelashwa kwamakhemikhali, indlela yokwelashwa kwamalangabi, indlela yokwelashwa yeCorona, indlela yokwelashwa kwemisebe ye-ultraviolet, njll. Indlela yokwelashwa yamakhemikhali ikakhulukazi ukwethula ama-Pollor Amaqembu okususa izithasiselo ebusweni befilimu.

Umgomo osebenzayo wendlela yokwelashwa kwamalangabi ukuvumela ifilimu lepulasitiki ngokushesha kudlule ilangabi elingaphakathi, futhi lisebenzise izinga lokushisa lelangabi lokukhiqiza umoya ukukhiqiza i-radicals yamahhala, bese usabela ebusweni befilimu entsha futhi bashintshe ifilimu. izakhiwo ezingaphezulu kokwenza ngcono ukunamathela ku-ink. Izinto zefilimu eziphathisiwe kufanele ziphrintwe ngokushesha okukhulu, uma kungenjalo indawo entsha izohanjiswa ngokushesha, okuzothinta umphumela wokwelashwa. Ukwelapha amalangabi kunzima ukulawula futhi manje sekuthathelwe indawo ukwelashwa kweCorona kokukhipha.

Umgomo osebenzayo wokwelashwa kokukhishwa kweCorona ukudlulisa ifilimu ngensimu ye-voltage, ekhiqiza ama-pulses averecy ama-oscillating aphoqa umoya ku-ionesie. Ngemuva kwe-ionization, igesi ion iyamangaza kwifilimu ukwandisa ukuqina kwayo.

Ngasikhathi sinye, ama-athomu we-oksijini wamahhala ahlangana nama-molecule we-oksijini ukukhiqiza i-ozone, namaqembu ama-polar akhiqizwa ebusweni, okugcina kwandisa ukungezwani kwefilimu yepulasitiki, okuvumelana nokunamathela kwama-inks kanye nama-adfives.
