Umhlahlandlela: Ukuphrinta usilika kuyinqubo evamile kakhulu yokuphrinta imidwebo ekwakhiweni kwezinto zokupakisha izimonyo. Ngokuhlanganisa uyinki, isikrini sokuphrinta isikrini, kanye nemishini yokuphrinta isikrini, uyinki udluliselwa ku-substrate nge-mesh yengxenye yesithombe. Phakathi nenqubo, ukuphrinta kwesikrini Umbala uzothinteka yizici ezithile kanye noshintsho. Lesi sihloko sipakishwe yiiphakheji yothingo lwaseShanghai, futhi ngizokwabelana nawe ngezinto eziningana ezithinta ukushintsha kombala kwesikrini sikasilika.
ukuphrinta kwesikrini
Inqubo yokunyathelisa isikrini iwukuthi uyinki udlula engxenyeni ye-mesh yesikrini bese uvuza ungene kwi-substrate. Ingxenye esele yesikrini ivinjiwe futhi uyinki awukwazi ukungena. Uma unyathelisa, uyinki uthululwa esikrinini. Ngaphandle kwamandla angaphandle, uyinki ngeke uvuze nge-mesh uye kwi-substrate. Lapho i-squeegee iklwebha uyinki nge-engeli ethile yokucindezela kanye nokuthambekela, izodlula esikrinini. Ku-substrate elandelayo ukuze kutholakale ikhophi yesithombe.
01 Ukuxuba uyinki
Uma sicabanga ukuthi imibala ekuyinki yenziwe kahle, imbangela evamile yokushintsha kombala yi-solvent eyengeziwe. Eshabhu elilawulwa kahle, uyinki kufanele inikezwe umshini wokunyathelisa nganoma yisiphi isikhathi ngemva kokuba isilungile, okungukuthi, iphrinta akufanele ixube uyinki.
