Izikrini Zomshini Wokuphrinta: Umgogodla Wezinhlelo Zokuphrinta Zesimanje

Isingeniso

Imishini yokunyathelisa iyishintshile indlela esixhumana ngayo nokusabalalisa ulwazi. Kusukela emaphephandabeni kuya kumalebula okupakisha, le mishini idlala indima ebalulekile embonini yesimanje yokunyathelisa. Ngemuva kwawo wonke amasistimu wokuphrinta aphumelele kukhona umgogodla - izikrini zomshini wokuphrinta. Lezi zikrini zinesibopho sokudlulisa isithombe ku-substrate, ziqinisekisa ukuphrinta okunembayo kanye nekhwalithi ephezulu. Kulesi sihloko, sizocubungula ubunkimbinkimbi bezikrini zemishini yokunyathelisa, ukubaluleka kwazo, nokuthi zinegalelo kanjani ekusebenzeni kahle nasekukhiqizeni inqubo yokunyathelisa.

Ukusebenza Kwezikrini Zomshini Wokuphrinta

Izikrini zomshini wokuphrinta, ezaziwa nangokuthi izikrini ze-mesh noma ama-stencil, zakha ingxenye ebalulekile yenqubo yokuphrinta. Akhiwe ngemeshi elukwe ngokuyinkimbinkimbi, ngokuvamile eyenziwe ngezinto ezifana ne-polyester noma inayiloni, esebenza njengohlaka lokuthwala uyinki uye endaweni engaphansi. Umsebenzi oyinhloko walezi zikrini ukuhlinzeka ngendawo enembile nelawulwayo ukuze uyinki adlulisele isithombe osifunayo kokubalulekile okuqondiwe.

Isibalo semeshi noma inani lemicu ngeyintshi ngayinye inquma ubuhle besikrini. Isibalo esiphezulu se-mesh sikhiqiza amaphrinti amahle, afanele imiklamo eyinkimbinkimbi nemininingwane emincane. Ngokuphambene, isibalo esiphansi semeshi sivumela amadiphozithi kayinki aminyene, okuyenza ifanele ukuphrinta okugqamile nokugqamile. Ukukhethwa kokubala kwe-mesh kuncike ezicini eziningana, okuhlanganisa uhlobo lwenqubo yokuphrinta, ukulungiswa kwesithombe esifunekayo, nezici ze-substrate.

Intuthuko Ezikrinini Zomshini Wokuphrinta

Ngokuhamba kweminyaka, izikrini zemishini yokunyathelisa ziye zabona intuthuko enkulu, okunomthelela ekuthuthukisweni kwamakhono okuphrinta. Ukwethulwa kwezikrini ezine-high-tension kuholele ekubhaliseni okuthuthukisiwe, ukunemba, nokuvumelana kumaphrinti. Lezi zikrini, ezenziwe ngezinto eziklanywe ngokukhethekile, zingamelana namazinga aphezulu wokungezwani, okuvumela ukulawula kukayinki okungcono nezithombe ezibukhali.

Intuthuko kubuchwepheshe bokumboza isikrini nayo idlale indima ebalulekile ekuthuthukiseni ukusebenza kwezikrini zemishini yokunyathelisa. Ukuthuthukiswa kwezingubo ze-emulsion ezinokunamathela okuphezulu nokuqina kubangele impilo yesikrini eside kanye nezidingo zokunakekelwa ezincishisiwe. Ukwengeza, ukwethulwa kwemishini yokwenza i-stencil, njengezinhlelo ze-emulsion eziqondile kanye nobuchwepheshe bekhompiyutha kuya kwesikrini, yenze yaba lula inqubo yokwenza isikrini, konga isikhathi nokuthuthukisa ukusebenza kahle okuphelele.

Ukubaluleka Kokulungiswa Kwesikrini Okufanelekile

Ukuze uthole imiphumela elungile yokuphrinta, ukulungiselela okufanele kwesikrini kubalulekile. Ukuqinisekisa ukuhlanzeka nokushuba okulungile kwesikrini kubalulekile ukuze kuzuzwe ukubhaliswa okunembile nokuvimbela ukuvuza kukayinki. Ukuhlanza isikrini ngaphambi kokusetshenziswa ngakunye kususa noma yimuphi uyinki oyinsalela noma izinsalela ezingase zithiye ikhwalithi yokuphrinta. Ukwengeza, ukuhlolwa okujwayelekile kwengcindezi nokulungiswa kuqinisekisa ukubolekwa kweyinki okufanayo nokufanayo.

Ukulungiswa kahle kwesikrini kuhlanganisa nokukhethwa kohlobo lwe-stencil olufanele. Izinhlelo zokusebenza zokuphrinta ezihlukene zibiza izinhlobo ezahlukene zama-stencil, njenge-emulsion eqondile, ifilimu ye-capillary, noma ifilimu yokudlulisa ukushisa. Ukukhetha kuncike ezintweni ezinjengobunkimbinkimbi bomklamo, i-substrate material, kanye nekhwalithi yokuphrinta efiselekayo. Ukukhetha uhlobo lwe-stencil olulungile kuqinisekisa ukugeleza kwe-inki nokubambelela okufanele, okuholela ekuphrinteni okubukhali nokucaciswe kahle.

Ukuxazulula izinkinga nokugcinwa kwezikrini zomshini wokuphrinta

Ngisho nokulungiselela kahle kwesikrini, izikrini zomshini wokuphrinta zingase zihlangabezane nezinkinga ngezikhathi ezithile ezidinga ukuxazululwa kwezinkinga. Inkinga eyodwa evamile ukuvela kwamaphinikhodi noma izikhala ku-stencil, okungaholela ekuphrinteni okungaphelele noma okuhlanekezelwe. Ama-Pinholes angabangelwa izici ezihlukahlukene, okuhlanganisa isikhathi sokuchayeka esinganele, isicelo se-emulsion esingafanele, noma udoti wangaphandle esikrinini. Ukuhlonza nokubhekana nalezi zinkinga ngokushesha kubalulekile ukuze kugcinwe ikhwalithi yamaphrinti.

Ukunakekelwa okuvamile kwezikrini zomshini wokunyathelisa kubalulekile ukuze kunwetshwe ukuphila kwazo nokuqinisekisa ukusebenza okungaguquki. Ukugcinwa okufanele, ukuhlanzwa, kanye nokuphathwa kwezikrini kubalulekile ukuze kuvinjelwe ukuguga ngaphambi kwesikhathi. Ukwengeza, kufanele kuhlolwe njalo ukuze kubonakale noma yimuphi umonakalo ongase ube khona noma ukuwohloka. Ukulungisa ngokushesha noma ukushintshwa kungasiza ekuvimbeleni ukubambezeleka kokukhiqiza nokugcina ukukhiqiza okuphelele kwesistimu yokuphrinta.

Ikusasa Lezikrini Zomshini Wokuphrinta

Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ikusasa lezikrini zemishini yokunyathelisa linamathuba ajabulisayo. Imizamo yocwaningo nentuthuko igxile ekuthuthukiseni ukuqina, ukulungiswa, kanye nokuguquguquka kwezikrini. I-Nanotechnology, isibonelo, inikeza amandla okuthuthukisa izikrini ezinama-nano-scale apertures, okuvumela ukuphrinta okuhle nakakhulu nokunembe kakhudlwana. Ngaphezu kwalokho, ukuhlanganiswa kwezinto ezisetshenziswayo zesikrini esihlakaniphile nezindawo zokuziphilisa kungase kunciphise isidingo sokunakekelwa njalo nokulungiswa.

Kukhona futhi umkhuba okhulayo obheke kuzixazululo zokuphrinta ezinobungani bemvelo. Ngenxa yalokhu, abakhiqizi bahlola izinto ezisimeme zokukhiqizwa kwesikrini, njengezinketho ze-eco-friendly mesh kanye ne-bio-degradable emulsion coatings. Lezi zindlela ezintsha zihlose ukunciphisa umthelela wemvelo wemboni yokunyathelisa kuyilapho kugcinwa amazinga aphezulu okuphrinta.

Isiphetho

Izikrini zemishini yokuphrinta zingamaqhawe angaqanjwanga ngemuva kwamaphrinti amangalisayo esihlangana nawo ekuphileni kwethu kwansuku zonke. Ukwakhiwa kwazo okuyinkimbinkimbi, ukusebenza kwayo okunembayo, nentuthuko eqhubekayo kunomthelela ekusebenzeni kahle nasekukhiqizeni izimiso zesimanje zokunyathelisa. Ukulungiswa kwesikrini okufanele, ukuxazulula inkinga, nokunakekelwa kubalulekile ukuze kuzuzwe ikhwalithi yokuphrinta elungile kanye nokwelula isikhathi sokuphila sezikrini. Njengoba ubuchwepheshe buthuthuka, ikusasa lezikrini zemishini yokuphrinta linamandla amakhulu ezisombululo zokuphrinta ezingcono kakhulu nezisimeme. Ngakho ngesikhathi esilandelayo lapho uhlangana nento ephrintiwe kahle, khumbula indima ebalulekile edlalwa izikrini zemishini yokunyathelisa - umgogodla wezinhlelo zokunyathelisa zesimanje.
