Izikrini Zomshini Wokuphrinta: Izingxenye Eziyinhloko Zezinhlelo Zokuphrinta Ezithuthukisiwe

Izingxenye Eziyinhloko Zezinhlelo Zokuphrinta Ezithuthukile

Isingeniso:

Imishini yokunyathelisa idlala indima ebalulekile emhlabeni wethu wanamuhla, yenza kube lula ukukhiqizwa kwezinto eziphrintiwe ezingenakubalwa esizithola nsuku zonke. Ngemuva kwezigcawu, lezi zinhlelo zokuphrinta ezithuthukisiwe ziqukethe izingxenye ezimbalwa ezibalulekile ezisebenza ndawonye ngaphandle komthungo ukuze zenze amaphrinti ekhwalithi ephezulu. Phakathi kwalezi zingxenye, izikrini zomshini wokunyathelisa zinokubaluleka okungenakuphikwa. Kulesi sihloko, sizocubungula izingxenye ezibalulekile zezinhlelo zokuphrinta ezithuthukile, sikhanyisele ukubaluleka nokusebenza kwezikrini zemishini yokunyathelisa.

1. Ukuqonda Izikrini Zomshini Wokuphrinta

Izikrini zomshini wokuphrinta, ezaziwa nangokuthi izikrini ze-mesh noma izikrini, ziyingxenye ebalulekile yenqubo yokuphrinta. Lezi zikrini zenziwe nge-mesh elukwe ngobunono, ngokuvamile ezakhiwe ngezinto ezifana ne-polyester, inayiloni, noma insimbi engagqwali. Inetha liyelulelwa futhi linamathiselwe ohlakeni oluqinile, lwenze indawo eyi-taut esebenza njengesisekelo senqubo yokunyathelisa. Izikrini ze-mesh ziza ngosayizi abahlukahlukene kanye nezibalo ze-mesh, okuvumela ukuguquguquka nokwenza ngokwezifiso ngokuya ngezidingo zokuphrinta ezithile.

Izikrini zomshini wokuphrinta zisebenza njengomsele wokudlulisa umklamo ezindaweni ezihlukene. Babambe iqhaza elibalulekile lokulawula ukugeleza kukayinki nokuqinisekisa ukukhiqizwa kabusha kwesithombe okunembayo. Izikrini zokuphrinta zinezikhala ezincane, noma izimbobo ezinezikhala, ezivumela u-inki ukuthi adlule phakathi nenqubo yokuphrinta. Isibalo semeshi sinquma inani lokuvuleka ngeyintshi ngayinye yomugqa, okuthonya izinga lemininingwane nokulungiswa okungazuzwa.

2. Ukukhethwa Kwemeshi Nokwenza Ngokwezifiso

Ukukhethwa kwemeshi efanelekile yesistimu yokuphrinta ethuthukisiwe kubalulekile ukuze kuzuzwe ikhwalithi yokuphrinta oyifunayo. Kunezici ezihlukahlukene okufanele zicatshangelwe lapho ukhetha i-mesh efanelekile, okuhlanganisa uhlobo lukayinki olusetshenziswayo, i-substrate material, nezidingo zokulungiswa kwesithombe.

Isibalo semeshi sisho inombolo yokuvuleka kwemeshi ngeyintshi ngalinye lomugqa. Izibalo eziphezulu ze-mesh, ezifana nama-280 noma 350, zincanyelwa kumadizayini ayinkimbinkimbi futhi anemininingwane, kuyilapho izibalo ezinezikhala eziphansi, ezifana nokungu-86 noma 110, zifanele ukuphrinta okugqamile nokukhanyayo. Lokhu ngokwezifiso kuvumela izikrini zomshini wokuphrinta ukuthi zihlangabezane nezidingo eziningi zokuphrinta.

I-mesh material nayo idlala indima ebalulekile enqubweni yokuphrinta. Izikrini ze-polyester mesh zidumile ngenxa yokuthengeka kwazo, ukuqina, nokumelana namakhemikhali. Ngakolunye uhlangothi, izikrini ze-nylon mesh, zinikeza ukunwebeka okuhle kakhulu futhi zilungele izinhlelo zokusebenza ezidinga ukwelula nokushuba. Izikrini zensimbi engagqwali ziqinile futhi azikwazi ukugqwala, zizenza zifanelekele ukuphrinta kwevolumu ephezulu kanye nezimboni.

3. Iqhaza Lokushuba Nokucindezela Kwe-Squeegee

Ukuthola ukungezwani okungaguquki kuso sonke isikrini somshini wokuphrinta kubalulekile ukuze kuqinisekiswe imiphumela elungile yokuphrinta. Ukushuba kwesimo sesikrini kunquma ukulawula nokufana kokufakwa kukayinki. Ukungezwani okwanele kungase kubangele ukuvuza kukayinki noma ukuphrinta okungahambisani, kuyilapho ukungezwani ngokweqile kungabangela ukulimala kwemeshi ngaphambi kwesikhathi futhi kuthinte ukubhaliswa kwesithombe.

Ukuze kuzuzwe futhi kugcinwe ukushuba okufiswayo, amasistimu okuphrinta athuthukile asebenzisa izinto ezicindezelayo ezelula izikrini zemeshi ngokufanayo. Lawa madivayisi avumela ukulungiswa okunembile, okuqinisekisa ukuthi ukungezwani kusatshalaliswa ngokulinganayo kuso sonke isikrini. Ukugcina ukungezwani okungaguquki kuyinqubo eqhubekayo edinga ukuhlolwa nokulungiswa ngezikhathi ezithile.

Ngokuhambisana nokushuba, ukucindezela kwe-squeegee nakho kuthinta inqubo yokuphrinta. I-squeegee, i-rubber blade efakwe esibanjeni, isetshenziselwa ukufaka ingcindezi kuyinki kusikrini se-mesh, ukuyiphoqa ngokusebenzisa izimbobo ze-mesh ku-substrate. Ukucindezela kwe-squeegee okufanelekile kuqinisekisa ukudluliswa kwe-inki okufanele, kuvimbele ukopha kwe-inki noma ukuhlambalaza. Ubungcweti bengcindezi ye-squeegee bubalulekile ekuzuzeni ukuphrinta okunamandla nokunembile.

4. Emulsion Coating kanye Image Ukulungiselela

Ngaphambi kokuthi inqubo yokuphrinta iqale, isikrini se-mesh sithola ukumbozwa kwe-emulsion nokulungiswa kwesithombe. I-emulsion, into engezwani nokukhanya, isetshenziswa endaweni enezikhala, idale i-stencil ezovumela ukuthi uyinki udlule ezindaweni ezithile ngesikhathi sokuphrinta. Le stencil idalwe ngokudalula isikrini semeshi esinamekwe ekukhanyeni kwe-ultraviolet (UV) ngefilimu evumayo enomklamo.

Ukulungiswa kwesithombe kuhilela ukulungiselela umklamo oyifunayo noma umsebenzi wobuciko wokuphrinta. Endabeni yokuphrinta isikrini, lokhu kuvame ukuhlanganisa ukuguqula idizayini ibe yisithombe esimnyama nesimhlophe esinokugqama okuphezulu esizosebenza njengefilimu enhle. Ifilimu i-positive ibe ibekwa phezu kwesikrini esimboziwe, futhi ukukhanya kwe-UV kwenza i-emulsion ibe lukhuni ezindaweni ezihambisana nezakhi zokuklama.

Uma ukuvezwa kwe-UV sekuqediwe, isikrini sihlanjululwa ngamanzi, sikhipha i-emulsion engaveziwe futhi sishiye ngemuva i-stencil enembile endaweni enezikhala. Isikrini esifakwe i-emulsion manje sesilungele ukusetshenziswa kweyinki kanye nenqubo yokuphrinta ukuze iqale.

5. Isondlo Nokuphila Isikhathi Eside

Ukuqinisekisa ukuphila isikhathi eside nokusebenza kahle kwezikrini zomshini wokunyathelisa, ukunakekelwa okufanele kubalulekile. Ukuhlanzwa okuvamile kwezikrini ngemva kokuphrinta ngakunye kusiza ukuvimbela izinsalela zikayinki nokwakheka okungase kuthinte ukuphrinta okulandelayo. Izixazululo zokuhlanza ezenzelwe ukuphrinta isikrini zinconywa ukugwema ukulimala kwemeshi noma i-emulsion.

Ngaphezu kokuhlanza okujwayelekile, ukuhlolwa kanye nokulungiswa ngezikhathi ezithile kuyadingeka ukuze kubhekwane nanoma yiziphi izimpawu zokuguga. Izikrini zemeshi ezilimele noma ezidabukile kufanele zishintshwe ngokushesha noma zilungiswe ukuze kugwenywe ukuphazamisa ikhwalithi yokuphrinta. Ukugcinwa okufanele, njengokugcina izikrini ziphansi futhi zivikelekile othulini nakumswakama, kwandisa isikhathi sazo sokuphila.

Isiphetho:

Izikrini zemishini yokuphrinta ngokungangabazeki ziyizingxenye ezibalulekile zesistimu yokuphrinta ethuthukisiwe, edlala indima ebalulekile ekuzuzeni amaphrinti ekhwalithi ephezulu. Ngesakhiwo sazo esiyinkimbinkimbi semeshi, lezi zikrini zilawula ukugeleza kweyinki, zisiza ukuphinda zenziwe kabusha kwesithombe, futhi zinike amandla amadizayini anembayo ukuthi aphrintwe ezindaweni ezihlukahlukene. Ngokwenza ngendlela oyifisayo, ukuqina, nokunakekelwa, lezi zikrini zingaletha ukuphrinta okungaguquki futhi okunempilo, kuzenze zibaluleke kakhulu kwezohwebo, ezobuciko, nezimboni. Ngakho-ke, ngesikhathi esilandelayo lapho uhlangabezana nokuphrinta okumangalisayo, thatha isikhashana ukwazisa umsebenzi oyinkimbinkimbi ofezwa izikrini zemishini yokunyathelisa evame ukunganakwa.
