Izikrini Zokuphrinta Isikrini: Izinto Ezibalulekile Zokuthola Imiphumela Ephrintiwe Yekhwalithi Ephezulu

Isingeniso:

Ukuphrinta isikrini kuyindlela edumile esetshenziselwa ukuphrinta imiklamo yekhwalithi ephezulu ezintweni ezihlukahlukene njengezingubo, amaphosta, nezimpawu. Ukuze uthole imiphumela evelele, kubalulekile ukunaka izici ezibalulekile zezikrini zokuphrinta isikrini. Lezi zici zidlala indima ebalulekile ekunqumeni ukucaca, ukuqina, kanye nekhwalithi iyonke yomphumela ophrintiwe. Kulesi sihloko, sizocubungula izici ezinhlanu ezibalulekile ezibalulekile ekuzuzeni imiphumela emihle kakhulu ephrintiwe ngezikrini zokuphrinta isikrini.

Ukubaluleka kwe-High-Quality Mesh:

Iqiniso eliqinisekisiwe embonini yokuphrinta isikrini ukuthi ikhwalithi ye-mesh inomthelela omkhulu emiphumeleni yokugcina ephrintiwe. I-mesh isebenza njengesisekelo lapho uyinki ebekwe phezu kwayo futhi inquma ukuthi mingakanani imininingwane nokucaca okungafezwa. Lapho ukhetha i-mesh, kubalulekile ukucabangela izici ezifana nokubala kwentambo, i-mesh material, nokudonsa kwe-mesh.

Ukubalwa kwentambo ephakeme kubonisa i-mesh ecolekile, evumela imininingwane emincane nemiphetho ebukhali ekuphrintiwe. Ngokuvamile, isibalo sentambo esiphezulu siyakhethwa kumiklamo eyinkimbinkimbi noma umbhalo ocolekile. Ngokuphambene, inani lentambo eliphansi lifanele imiklamo enesibindi nemikhudlwana. Kubalulekile ukukhetha inetha elilinganisa ileveli oyifunayo yemininingwane nokugeleza kukayinki okudingekayo kumklamo othile.

Ngokungeziwe ekubalweni kwentambo, okokusebenza kwemeshi nakho kungathinta imiphumela ephrintiwe. Izinto ezisetshenziswa kakhulu ezinezikhala ezisetshenziswa ekuphrinteni isikrini i-polyester, inayiloni, nensimbi engagqwali. Ama-polyester meshes adumile ngenxa yokugeleza kwawo kweyinki okuhle kakhulu, ukuqina, nokumelana namakhemikhali. Amameshi enayiloni anikeza izinzuzo ezifanayo kodwa avame ukuthengeka kakhulu. Amameshi ensimbi engagqwali ahlala isikhathi eside kakhulu futhi anikezela ngokulawula ukushuba okuphezulu, okuwenza alungele ukuphrinta kwevolumu ephezulu.

I-mesh tension ingesinye isici esibalulekile okufanele sicatshangelwe. Ukushuba okufanelekile kuqinisekisa ukuthi i-mesh ihlala izinzile phakathi nenqubo yokuphrinta, okuholela ekubhaliseni okunembile kanye nokuphrinta okucacile. Ukungezwani okunganele kungaholela ekuvuzeni kukayinki nokuphrinta okufiphele, kuyilapho ukungezwani okweqile kungabangela ukwehluleka kwemeshi ngaphambi kwesikhathi kanye nobunzima emhubheni kayinki. Ukuhlola njalo nokulungisa ukungezwani kwemeshi kubalulekile ukuze kugcinwe ikhwalithi yokuphrinta engaguquki.

Iqhaza Le-Emulsion Ekuzuzeni Ukuphrinta Okubukhali:

I-Emulsion iyinamathela e-photosensitive esetshenziswa kuma-mesh ngaphambi kokuphrinta. Isebenza njenge-stencil, evumela ukuthi uyinki udlule lapho umklamo uyalela khona. Ikhwalithi kanye nokusetshenziswa okufanele kwe-emulsion kunomthelela omkhulu ekukhanyeni nasekucaceni kwesithombe esiphrintiwe.

Ukukhetha i-emulsion efanele yomsebenzi kubalulekile. Kunezinhlobo ezimbili eziyinhloko: i-emulsion eqondile nefilimu ye-capillary. I-emulsion eqondile iguquguquka futhi ivame ukusetshenziselwa izinhlelo eziningi ezahlukene. Inikeza ukulungiswa okuhle kakhulu nokuqina. Ngakolunye uhlangothi, ifilimu ye-capillary ithandwa kakhulu ngemiklamo enemininingwane eminingi nemigqa emihle.

Ukusetshenziswa kwe-emulsion efanele kubaluleke ngokufanayo. Kufanele iboshwe ngokulinganayo ezinhlangothini zombili ze-mesh ukuqinisekisa ukuthi i-stencil ifana. Inqubo yokugqoka kufanele yenziwe endaweni elawulwayo, ngaphandle kothuli nokungcola, ukugwema ukungapheleli ku-stencil. Isikhathi esanele sokumisa sibalulekile ukuvimbela ukuchayeka ngaphambi kwesikhathi nokugcina izinga elidingekayo lemininingwane.

Ukuqina Kwesikrini: Kubalulekile Ukuze Ubhalise Okunembile:

Ukuqina kwesikrini kuyisici esibalulekile esithinta ukunemba kokubhaliswa ekuphrinteni isikrini. Ukubhalisa kubhekisela ekuqondaneni kwemibala ehlukene noma izendlalelo ngaphakathi komklamo. Ukubhaliswa okufanele kubalulekile ukuze uthole ukuphrinta okuhlanzekile nokugqamile, ikakhulukazi uma usebenza ngemiklamo enemibala eminingi noma umsebenzi wobuciko oyinkimbinkimbi.

Ukugcina ukungezwani okungaguquki kuzo zonke izikrini kubalulekile ekubhaliseni okunembile. Uma izikrini zinokungezwani okuhlukahlukene, kuba yinselele ukuqondisa isendlalelo ngasinye ngokunembile. Lokhu kungase kubangele isipoki, ukubhaliswa kabi, noma izikhala phakathi kwemibala, kwehle ikhwalithi yokuphrinta iyonke.

Ukuhlolwa kwengcindezi okuvamile nokulungiswa kuyadingeka ukuze kuqinisekiswe imiphumela engaguquki. Imitha ye-tension ingasetshenziswa ukukala nokuqapha ukushuba kwesikrini ngasinye. Uma ukuhlukahluka kutholwa, ukulungiswa kufanele kwenziwe ngokuqiniswa noma ukuxegiswa kwe-mesh ngokufanele.

Izikhathi Zokuchayeka Ezifanelekile: Ukuqinisekisa Ukudluliselwa Kwesithombe Okufanelekile:

Isikhathi sokuchayeka sidlala indima ebalulekile ekuphrinteni kwesikrini njengoba sinquma ikhwalithi nokucaca kwesithombe esidlulisiwe. Ukuchayeka kancane kungabangela ukudluliswa kwesithombe okunganele, okuholela ekuphrinteni okungaphelele noma okugeziwe. Ukuchayeka ngokweqile, ngakolunye uhlangothi, kungabangela imininingwane emihle yomklamo ukuba ilahleke noma kubangele i-stencil eqinile okuyinselele ukuyihlanza.

Isikhathi sokuchayeka esilungile sincike ezintweni ezimbalwa, njengohlobo lwe-emulsion, isibalo semeshi, namandla omthombo wokukhanya. Kubalulekile ukwenza izivivinyo zokuchayeka ukuze uthole ibhalansi efanele phakathi kwencazelo yesithombe nokuqina kwe-stencil. Lezi zivivinyo zibandakanya ukuveza igxathu lesinyathelo noma isithombe sokuhlola esinezikhathi zokuchayeka ezehlukene ukuze kutholwe ubude besikhathi obufanelekile bokuthola imiphumela efiselekayo.

Ukuqinisekisa ukuchayeka okungaguquki, kuyatuseka ukusebenzisa iyunithi yokuchayeka ku-vacuum enikeza ingcindezi efanayo futhi ivimbele izikhala zomoya phakathi kwefilimu ephozithivu kanye nenetha. Ukwengeza, ukulinganisa njalo umthombo wokukhanya kuqinisekisa izikhathi zokuchayeka ezinembile nemiphumela ethembekile.

Ukuhlanza nokunakekelwa okufanele:

Ukugcina ubuqotho nempilo ende yezikrini zokuphrinta isikrini, ukuhlanzwa okufanele nokunakekelwa kubalulekile. Ukuhlanza okuvamile kuvimbela ukunqwabelana kukayinki, kuqinisekisa ukugeleza kukayinki okungaguquki, futhi kulondoloza ikhwalithi yamaphrinti esikhathi esizayo.

Ngemva kokuphrinta ngakunye, izikrini kufanele zihlanzwe kahle ukuze kukhishwe noma iyiphi inki eyinsalela noma i-emulsion. Lokhu kungenziwa kusetshenziswa izixazululo zokuhlanza isikrini eziklanyelwe inhloso. Kubalulekile ukugwema amakhemikhali anokhahlo angalimaza i-mesh noma i-emulsion. Ukukhuhla ngobumnene ngebhulashi elithambile noma isipontshi, okulandelwa ukugeza ngamanzi, ngokuvamile kwanele.

Ngaphezu kokuhlanza, ukuhlola izikrini ngomonakalo ofana nezinyembezi, izimbobo, noma izindawo ezeluliwe kubalulekile. Izikrini ezilimele zidinga ukulungiswa noma ukushintshwa ukuze kugcinwe ikhwalithi yokuphrinta futhi kuvinjwe ukuvuza kwe-inki ngesikhathi sokuphrinta.

Isiphetho:

Ukuthola imiphumela ephrintiwe yekhwalithi ephezulu ekuphrinteni kwesikrini kuncike kakhulu ekunakeni izinto ezibalulekile njengekhwalithi yemeshi, ukusetshenziswa okufanele kwe-emulsion, ukushuba kwesikrini okungaguquki, izikhathi zokuchayeka ezilungile, kanye nokuhlanza nokugcinwa okuvamile. Ngayinye yalezi zici inikela ekucaceni okuphelele, ukuqina, kanye nokunemba komklamo ophrintiwe. Ngokuqonda nokusebenzisa lezi zici ngempumelelo, amaphrinta esikrini angaphakamisa ubuciko bawo futhi akhiqize amaphrinti akhethekile aheha iso futhi akwazi ukumelana nesikhathi.
