Isikrini se-Silkscreen ku-Graphic Arts: Umhlahlandlela Ophelele
I-Silkscreen—evame ukubizwa ngokuthi ukuphrinta kwesikrini—ingenye yezindlela ezithandwa kakhulu kwezobuciko bezithombe ngoba ikhiqiza ukuphrinta okuqinile, okunemibala ecebile, futhi okulula ukukuphinda. Le ndlela isetshenziswa emhlabeni wobuciko obuhle, ukuklama, kanye nemboni (ama-T-shirt, amaphosta, ukupakishwa), kodwa isenenani eliphezulu lobuciko ngoba inqubo "isebenza ngezandla" futhi ivula amathuba amaningi okuhlola okubonakalayo. Lesi sihloko sixoxa nge-silkscreen iyonke: kusukela encazelweni yayo, umlando, amathuluzi nezinto zokwakha, inqubo, kuya kumathiphu okuphrinta okucocekile nokuvumelanayo.
Kuyini isikrini sesilika?
Ukunyathelisa nge-silkscreen kuyindlela yokunyathelisa nge-stencil esebenzisa i-mesh enwetshiwe phezu kohlaka (isikrini). Uyinki uphushwa nge-mesh evulekile kusetshenziswa i-squeegee, okudala isithombe ebusweni be-media (iphepha, indwangu, ipulasitiki, njll.). Izindawo okungafanele zinyatheliswe zimbozwe nge-emulsion noma enye indlela ye-stencil ukuvimbela uyinki ukuthi ingene kulezo zindawo.
Inzuzo eyinhloko yokunyathelisa nge-silkscreen yikhono layo lokukhiqiza amasimu anombala olinganayo, oqinile, nobukhali, ngisho nasezindaweni ezingafaneleki ngaso sonke isikhathi kwezinye izindlela zokunyathelisa . Ukunyathelisa nge-silkscreen nakho kuyaguquguquka: kungasetshenziswa kokubili ekunyathelisweni okulinganiselwe kanye nasekukhiqizweni ngobuningi.
Umlando omfushane wesikrini sesilika
Izimpande ze-silkscreen zingalandelelwa emasu okubhala ama-stencil e-Asia, ikakhulukazi eShayina naseJapan, ezazisebenzisa indwangu yesilika njengesihenqo. Intuthuko yayo yesimanje yenzeka lapho i-mesh (eyayiyisilika ekuqaleni, bese kuba yi-polyester) ihlanganiswa ne-photo emulsion kanye nobuchwepheshe bokuchayeka. Ekhulwini lama-20, i-silkscreen yathola ukuthandwa ekwakhiweni kwezentengiselwano kanye nobuciko be-pop. Abaculi abanjengo-Andy Warhol basize ekuphakamiseni i-silkscreen njengendlela esemthethweni yokuveza ubuciko, ikakhulukazi njengoba le ndlela ivumela ukuphindaphinda, ukuhlanganisa imibala, kanye nokuhlola izithonjana ezibonakalayo.
Kungani i-silkscreen ibalulekile kwezobuciko bezithombe?
Uma kukhulunywa ngobuciko bezithombe , isikrini se-silkscreen sivelele ngoba:
1. Umbala oqinile futhi ongacacile
Uyinki wokuphrinta isikrini uvame "ukumboza" kakhulu kunezinye izindlela zokuphrinta, ngakho imibala ibukeka inesibindi.
2. Ukwendlalela okunobuciko
Ungabeka izingqimba eziningi zombala (ezinezingqimba eziningi) ukuze udale imiphumela yokujula, ukuthungwa, kanye nokucaca.
3. Ukukhiqiza kabusha okuhambisanayo
Ifanele ukudala izinhlelo zemisebenzi yekhwalithi efanayo, uma nje ukubhaliswa kanye nokulawulwa kweyinki kuzinzile.
4. Ukuguquguquka kuzo zonke izinhlobo zemidiya
Kusukela ephepheni lobuciko kuya kwendwangu, ukhuni, i-acrylic, ngisho nezinto ezithile ze-3D (ezinamasu akhethekile).
Imishini nezinto eziyisisekelo
Ukuze uqale nge-silkscreening, nanka amanye amathuluzi avamile ongawasebenzisa:
– Isikrini (uhlaka + i-mesh): I-mesh inezinga lokuxinana (isb. 77T, 90T, 120T) elithinta imininingwane kanye nobukhulu beyinki.
– I-emulsion yesithombe: Uketshezi oluzwela ukukhanya lokwenza ama-stencil ezikrinini.
– I-Coater (ithuluzi lokufaka i-emulsion): Isiza ukusabalalisa i-emulsion ngokulinganayo esikrinini.
– Umthombo wokukhanya wokuchayeka: Kungaba isibani esikhethekile noma iyunithi yokuchayeka, kuye ngezidingo.
– Ifilimu ecacile (enhle): Iqukethe umklamo omnyama oqinile njengesivikelo sokukhanya.
– I-Squeegee: I-squeegee yerabha enobunzima obuthile bokucindezela uyinki.
– Uyinki wokuphrinta isikrini: Izinhlobo ezahlukene (osekelwe emanzini, i-plastisol, uyinki wesikrini se-acrylic) ngokusho kwemidiya.
– Phrinta ithebula/i-clamp/i-hinge: Kusiza ukubhalisa ukuze indawo yokuphrinta ihambisane.
– Isifutho/ishawa: Yenqubo yokuhlanza (ukuvula isithombe ngemva kokuvezwa).
– Izinto zokuhlanza: Isisusi se-emulsion, isihlanzi samafutha, kanye nesihlanzi se-inki—kubalulekile ekunakekelweni kwesikrini.
Izinhlobo zeyinki: iyiphi efanelekile?
Ukukhetha uyinki kunquma uhlamvu lomphumela wokugcina:
– Okusekelwe emanzini: Kunobungani kakhulu nemvelo, komisa ngokushesha, futhi kufanelekile emaphepheni nasezindwangu ezithile. Kodwa-ke, kudinga isivinini ngoba komisa kalula esikrinini.
– I-Plastisol: Ivamile kuma-t-shirt; uyinki uzinzile futhi awomi ngokushesha esikrinini, kodwa ngokuvamile udinga ukufudumeza ukuze uqine.
– Uyinki wesikrini se-Acrylic: Usetshenziswa kabanzi ephepheni/ekhavanini, ukhiqiza imibala egqamile futhi kulula ukuwusebenzisa.
Ngobuciko obunemifanekiso obusephepheni, abaculi bavame ukukhetha uyinki osekelwe emanzini noma we-acrylic ngoba “unobungani nobuciko obuhle” futhi utholakala ngemibala ehlukahlukene.
Isigaba sokuklama: kusukela emqondweni kuya ekuhlukanisweni kombala
Isikrini se-silk sisho ukuhlukaniswa kombala. Uma umsebenzi wakho unemibala eminingi, umbala ngamunye ngokuvamile udinga isikrini esihlukile.
Izinyathelo ezibalulekile:
1. Dala umklamo ucabangela inani lemibala.
2. Thola uhlelo lokuphrinta (ngokuvamile kusukela ekukhanyeni kuya ebumnyameni, nakuba kungenjalo ngaso sonke isikhathi).
3. Lungisa ifayela lokuhlukanisa: umbala ngamunye uba ungqimba lwawo.
4. Phrinta ifilimu enhle: indawo okufanele iphrintwe kumele ibe mnyama kakhulu ukuze ukukhanya kungangeni.
Uma ufuna ubuhle obusetshenziswa ngesandla, ukuhlukaniswa kungenziwa ngokudweba ngqo isimo ngombala ngamunye, esikhundleni sokuthembela kusofthiwe.
Inqubo yokuphrinta isikrini (ukwenza ama-stencil ezikrinini)
I-Afdruk iyisisekelo sesikrini sesilika sanamuhla:
1. Ukwehlisa amafutha
Hlanza isikrini kumafutha/uthuli ukuze i-emulsion inamathele kahle.
2. Ukugqoka kwe-emulsion
Faka i-emulsion ngokulinganayo usebenzisa i-coater. Hlosa ukujiya okufanayo.
3. Ukomisa
Yomisa isikrini ekamelweni elimnyama/elifiphele (ngoba i-emulsion iyazwela ekukhanyeni).
4. Ukuvezwa
Beka ifilimu eliqondile esikrinini, bese ulibeka ekukhanyeni isikhathi esifanele. Isikhathi siyahlukahluka kuye ngohlobo lwe-emulsion, ibanga ukusuka esibanini, kanye nobukhulu bokukhanya.
5. I-Washout
Futha isikrini ngamanzi. Izindawo ezimbozwe isithombe esimnyama zizoncibilika futhi zibe izindawo ezivulekile zeyinki.
Isihluthulelo sokuphrinta okuphumelelayo inhlanganisela efanele ye-emulsion, isikhathi sokuvezwa, kanye nekhwalithi yefilimu enhle.
Inqubo yokuphrinta: isinyathelo ngesinyathelo
Uma isikrini sesilungile, inqubo yokuphrinta ivame ukuhamba kanje:
1. Ukubhalisa
Beka iphepha noma imidiya etafuleni lokunyathelisa. Sebenzisa izimpawu zokubhalisa uma zinemibala eminingi.
2. Ukushaywa yizikhukhula
Hudula uyinki kancane ukuze ugcwalise indawo yesithombe esikrinini ngaphandle kokucindezela kakhulu.
3. Phrinta umbhalo
Cindezela i-squeegee nge-engeli eqinile (ngokuvamile engu-45°) bese udonsa ngokucindezela okulinganayo ukuze ufake uyinki ku-media.
4. Phakamisa isikrini bese uhlola imiphumela
Bheka ukuthi uyinki uyalingana noma kukhona yini izindawo ezingekho.
5. Ukomisa phakathi kwemibala (uma kunezingqimba eziningi)
Qiniseka ukuthi ungqimba lomile ngokwanele ngaphambi kokuphrinta umbala olandelayo ukuze ugweme ukugcotshwa.
6. Phinda ngezikhathi ezithile
Kuma-print edishini, gcina ukuqina kokucindezela, ubungako beyinki, kanye nesivinini.
Amasu obuciko avame ukusetshenziswa
Isikrini se-silk akudingeki sibe "sicaba futhi sihlanzekile." Kunezindlela eziningi zobuciko:
– I-Halftone: Idala ama-gradient esebenzisa amachashazi. Idumile kumaphosta.
– Ukuphrinta ngokweqile: Ukubeka imibala ecacile ukuze kudalwe imibala emisha.
– Umthombo ohlukanisiwe: Ukubeka imibala emibili kayinki esikrinini ngesikhathi esisodwa bese uvumela ukuxubana kwenzeke ngesikhathi sokuphrinta.
– Isikrini sokuthungwa: Ukwengeza ukuthungwa ngokusebenzisa amasu okuhlanganisa, okunamathelayo, noma ama-stencil ngesandla.
– Ukuphrinta kokunciphisa (inguqulo yesikrini se-silk): Ukushintsha isikrini esifanayo sesigaba ngasinye sombala (kuyingozi kakhulu, kodwa kuhlukile).
Amaphutha avamile nendlela yokulungisa lawo
1. Imiphumela yokuphrinta enamabala/engalingani
Izimbangela: ukucindezela okungalingani, uyinki ukhulu kakhulu/uncane kakhulu, noma i-mesh ayifaneleki.
Isixazululo: lungisa i-viscosity yeyinki, khetha i-mesh efanele, uzinzise i-engeli kanye nengcindezi ye-squeegee.
2. Imininingwane iyalahleka ngesikhathi sokuhlanza
Imbangela: ayibonakali ngokwanele noma i-emulsion incane kakhulu.
Isixazululo: khulisa isikhathi sokuvezwa, umboze ngokulinganayo, hlola ikhwalithi yefilimu enhle.
3. Ukuvuza kweyinki ezindaweni okufanele zimbozwe
Imbangela: i-emulsion eyonakele/enezimbobo, isikrini esingcolile, noma ukucindezela okukhulu.
Isixazululo: yenza ama-touch-up, hlola isikrini ngaphambi kokuphrinta, nciphisa ingcindezi.
4. Iphutha lokubhalisa ekuphrinteni okunemibala eminingi
Izimbangela: ukuhamba kwemidiya, ukugoba okuxegayo, uphawu lokubhalisa olungacacile.
Isixazululo: sebenzisa i-jig/clamp, yenza izimpawu zokubhalisa, gcina indawo yephepha ingaguquguquki.
Izici zokugcinwa kwesikrini kanye nokuphepha
Ukuhlola i-silkscreen kuyonga kakhulu uma isikrini singasetshenziswa kabusha. Uma sekuqediwe:
– Hlanza uyinki ngokushesha ukuze ungomi.
– Sebenzisa i-emulsion remover ukususa i-stencil uma ufuna umklamo omusha.
– Geza futhi womise kahle isikrini ukuze uvimbele isikhunta kanye nezinsalela.
Ngokuphepha:
– Qinisekisa ukuthi umoya ungena ngokwanele, ikakhulukazi uma usebenzisa amakhemikhali okuhlanza.
– Sebenzisa amagilavu kanye nokuvikela amehlo uma kudingeka.
– Gcina amakhemikhali kude nezingane kanye nemithombo yokushisa.
I-Penutup
I-Silkscreen iyindlela enamandla yokwenza ukuphrinta — ihlanganisa ukunemba kobuchwepheshe kanye nobubanzi obanele bokuhlola ngokudala. Ngokuqonda amathuluzi, inqubo yokuphrinta, ukulawula uyinki, kanye nokubhalisa, ungakhiqiza umsebenzi ohambisanayo futhi oveza imizwa. Kungakhathaliseki ukuthi ungowamaphosta anohlelo olulinganiselwe, imisebenzi ephepheni lobuciko obuhle, noma imikhiqizo kwezinye izinto, i-silkscreen inikeza ithuba lokudlala ngombala, ukuthungwa, kanye nezendlalelo ngendlela ehlukile. Uma usaqala nje, qala ngomklamo wombala owodwa ukuze ube yingcweti yezisekelo, bese usebenza ngendlela yakho kuze kube nemibala eminingi bese uzama amasu. Ngokuzijwayeza, i-silkscreen iba ngaphezu nje kwendlela yokuphrinta — ulimi olubonakalayo ongaluthuthukisa lube yisiginesha sakho.
