Izikrini zokuShicilela iSkrini: Izinto eziphambili zokuPhumelela iZiphumo eziShicileleyo ezikwiMgangatho oPhezulu

Intshayelelo:

Ukuprintwa kwesikrini yindlela edumileyo esetyenziselwa ukuprinta uyilo olukumgangatho ophezulu kwizinto ezahlukeneyo ezifana nempahla, iipowusta, kunye nemiqondiso. Ukufezekisa iziphumo ezigqwesileyo, kubalulekile ukunikela ingqalelo kwizinto eziphambili kwizikrini zokuprinta isikrini. Ezi zinto zidlala indima ebalulekileyo ekuqinisekiseni ukucaca, ukuqina, kunye nomgangatho opheleleyo wesiphumo esishicilelweyo. Kweli nqaku, siza kuphonononga kwimiba emihlanu engundoqo ebalulekileyo ekuphumezeni iziphumo eziprintiweyo ezigqwesileyo ngezikrini zoshicilelo lwesikrini.

Ukubaluleka komnatha okwiMgangatho oPhezulu:

Inyaniso eqinisekisiweyo kwishishini lokushicilela isikrini kukuba umgangatho we-mesh unempembelelo ebalulekileyo kwiziphumo eziprintiweyo zokugqibela. Umnatha usebenza njengesiseko apho i-inki ibekwe phezu kwayo kwaye imisela ukuba zingakanani iinkcukacha kunye nokucaca okunokuphunyezwa. Xa ukhetha umnatha, kubalulekile ukuqwalasela izinto ezinje ngokubala kwentambo, imathiriyeli yemesh, kunye nokuxinana komnatha.

Ubalo lwemisonto ephezulu lubonisa umnatha ocolekileyo, ovumela iinkcukacha ezicolekileyo kunye neencam ezibukhali kushicilelo. Ngokubanzi, inani eliphezulu lemisonto liyakhethwa kuyilo oluntsonkothileyo okanye umbhalo ocolekileyo. Ngokwahlukileyo, ukubala komsonto osezantsi kufanelekile kuyilo olunesibindi kunye nolukhulu. Kubalulekile ukukhetha i-mesh elinganisa inqanaba elifunekayo leenkcukacha kunye nokuhamba kwe-inki efunekayo kuyilo oluthile.

Ukongeza kwisibalo somsonto, izinto zemesh zinokuchaphazela iziphumo eziprintiweyo. Ezona zixhobo zixhaphakileyo zemesh ezisetyenziswa kushicilelo lwescreen yipolyester, inayiloni, kunye nentsimbi engatyiwayo. I-polyester meshes ithandwa kakhulu ngenxa yokuhamba kakuhle kwe-inki, ukuqina, kunye nokuxhathisa imichiza. Iimeshi zenayiloni zibonelela ngezibonelelo ezifanayo kodwa zithande ukufikeleleka ngakumbi. Iimeshi zensimbi ezingenasici zomelele kakhulu kwaye zibonelela ngolawulo oluphezulu loxinzelelo, nto leyo ebenza balungele ukuprintwa kwevolyum ephezulu.

Uxinzelelo lweMesh ngomnye umba obalulekileyo ekufuneka uqwalaselwe. Uxinzelelo olufanelekileyo luqinisekisa ukuba umnatha uhlala uzinzile ngexesha lenkqubo yokushicilela, okukhokelela ekubhaliseni okuchanekileyo kunye nokuprintwa okucacileyo. Uxinzelelo olungonelanga lunokubangela ukuvuza kwe-inki kunye noshicilelo olumfiliba, ngelixa uxinzelelo olugqithisileyo lunokubangela ukusilela kwangaphambili komnatha kunye nobunzima kwipaseji ye-inki. Ukuhlola rhoqo kunye nokulungelelanisa ukutsalwa kwemesh kubalulekile ukugcina umgangatho woshicilelo ongaguqukiyo.

Indima ye-Emulsion ekuphumezeni ushicilelo olubukhali:

I-Emulsion yingubo ye-photosensitive esetyenziswa kwi-mesh ngaphambi kokushicilela. Isebenza njenge-stencil, ivumela i-inki ukuba idlule kuphela apho uyilo luyalela. Umgangatho kunye nokusetyenziswa okufanelekileyo kwe-emulsion kunempembelelo ebalulekileyo ekubukhali kunye nokucaca komfanekiso oprintiweyo.

Ukukhetha i-emulsion efanelekileyo yomsebenzi kubalulekile. Kukho iintlobo ezimbini eziphambili: i-emulsion ngqo kunye nefilimu ye-capillary. I-emulsion ethe ngqo iyaguquguquka kwaye isetyenziswa ngokuqhelekileyo kuluhlu olubanzi lwezicelo. Inika isisombululo esihle kakhulu kunye nokuqina. Ifilimu yeCapillary, kwelinye icala, ikhethwa ngokuqhelekileyo kuyilo oluneenkcukacha kunye nemigca emihle.

Isicelo esifanelekileyo se-emulsion sibaluleke ngokufanayo. Kufuneka ifakwe ngokulinganayo kumacala omabini e-mesh ukuqinisekisa ukuba i-stencil ifana. Inkqubo yokugqoka kufuneka yenziwe kwindawo elawulwayo, ngaphandle kothuli kunye nokungcola, ukuphepha ukungafezeki kwi-stencil. Ixesha elaneleyo lokomisa libalulekile ukuthintela ukubonakala kwangaphambi kwexesha kunye nokugcina inqanaba elifunekayo leenkcukacha.

Uxinzelelo lweSkrini: Kubalulekile kuBhaliso oluchanekileyo:

Ukunyanzeliswa kwesikrini yinto ebalulekileyo echaphazela ukuchaneka kobhaliso ekushicileleni kwesikrini. Ubhaliso lubhekiselele kukulungelelaniswa kwemibala eyahlukeneyo okanye iileya ngaphakathi koyilo. Ukubhaliswa okufanelekileyo kubalulekile ukufezekisa ukuprintwa okucocekileyo kunye okubonakalayo, ngakumbi xa ujongene noyilo lwemibala emininzi okanye umsebenzi onzima wobugcisa.

Ukugcina uxinzelelo kuzo zonke izikrini kubalulekile kubhaliso oluchanekileyo. Xa izikrini zineengxabano ezahlukeneyo, kuba ngumngeni ukulungelelanisa umaleko ngamnye ngokuchanekileyo. Oku kunokubangela ukuba kubekho isiporho, ukungabhaliswa kakuhle, okanye izikhewu phakathi kwemibala, ukunciphisa umgangatho uwonke woshicilelo.

Ukuhlolwa rhoqo kwengcinezelo kunye nohlengahlengiso luyimfuneko ukuze kuqinisekiswe iziphumo ezihambelanayo. Imitha yoxinzelelo ingasetyenziselwa ukulinganisa kunye nokubeka iliso kuxinzelelo lwesikrini ngasinye. Ukuba iinguqu zifunyenwe, ukulungiswa kufuneka kwenziwe ngokuqiniswa okanye ukukhulula i-mesh ngokufanelekileyo.

Amaxesha Afanelekileyo okuVezwa: Ukuqinisekisa ukuGqithisela koMfanekiso ngokuLungileyo:

Ixesha lokuvezwa lidlala indima ebalulekileyo kushicilelo lwesikrini njengoko limisela umgangatho kunye nokucaca komfanekiso ogqithisiweyo. Ukubonakaliswa okungaphantsi kunokubangela ukugqithiswa komfanekiso okwaneleyo, okukhokelela kwiprints ezingaphelelanga okanye ezihlanjiweyo. Ukugqithiswa ngokugqithiseleyo, ngakolunye uhlangothi, kunokubangela ukuba iinkcukacha ezintle zoyilo zilahleke okanye zibangele i-stencil eqinile enzima ukuyicoca.

Ixesha elilelona lokuvezwa lixhomekeke kwizinto ezininzi, ezinje ngodidi lwe-emulsion, isibalo semesh, kunye nokuqina komthombo wokukhanya. Kubalulekile ukwenza iimvavanyo zokuvezwa ukufumana ibhalansi elungileyo phakathi kwenkcazo yomfanekiso kunye nokuqina kwestencil. Olu vavanyo lubandakanya ukuveza inyathelo okanye umfanekiso wovavanyo onamaxesha ahlukeneyo okuvezwa ukumisela ixesha elifanelekileyo lokufikelela kwiziphumo ezinqwenelekayo.

Ukuqinisekisa ukubonakaliswa okuhambelanayo, kuyacetyiswa ukuba kusetyenziswe i-vacuum exposure unit ebonelela ngoxinzelelo olufanayo kunye nokuthintela izithuba zomoya phakathi kwefilimu entle kunye ne-mesh. Ukongeza, ukulinganisa rhoqo umthombo wokukhanya kuqinisekisa amaxesha achanekileyo okuvezwa kunye neziphumo ezithembekileyo.

Ukucocwa ngokufanelekileyo kunye noLondolozo:

Ukugcina ingqibelelo kunye nokuphila ixesha elide kwezikrini zokuprinta isikrini, ukucocwa okufanelekileyo kunye nokugcinwa kubaluleke kakhulu. Ukucoca rhoqo kuthintela ukwakhiwa kwe-inki, kuqinisekisa ukuhamba kwe-inki okungaguqukiyo, kunye nokugcina umgangatho wokushicilela kwexesha elizayo.

Emva kokuqhutywa koshicilelo ngalunye, izikrini kufuneka zicocwe ngokucokisekileyo ukuze zisuse nayiphi na inki eshiyekileyo okanye i-emulsion. Oku kunokwenziwa ngokusebenzisa izisombululo zokucoca isikrini ezenzelwe injongo. Kubalulekile ukuphepha iikhemikhali ezinzima ezinokulimaza i-mesh okanye i-emulsion. Ukuxubha ngobunono ngebrashi ethambileyo okanye isipontshi, kulandele ukuhlanjululwa ngamanzi, ngokuqhelekileyo kwanele.

Ukongeza ekucoceni, ukuhlola izikrini ngomonakalo ofana neenyembezi, imingxuma, okanye iindawo ezoluliweyo kubalulekile. Izikrini ezonakeleyo kufuneka zilungiswe okanye zitshintshwe ukuze kugcinwe umgangatho wokuprinta kunye nokuthintela ukuvuza kwe-inki ngexesha lokuprinta.

Isiphelo:

Ukufezekisa iziphumo eziprintiweyo ezikumgangatho ophezulu ekushicileleni isikrini kuxhomekeke kakhulu kwingqalelo kwizinto eziphambili ezinjengomgangatho we-mesh, ukusetyenziswa okufanelekileyo kwe-emulsion, ukuxinzezeleka kwesikrini okungaguqukiyo, amaxesha afanelekileyo okuvezwa, kunye nokucoca kunye nokugcinwa rhoqo. Nganye kwezi zinto ifak’ isandla ekucaceni, ukuqina, nokuchaneka koyilo olushicilelweyo. Ngokuqonda kunye nokuphumeza ezi zinto ngokufanelekileyo, abashicileli besikrini banokuwuphakamisa umsebenzi wabo kwaye bavelise iiprinta ezikhethekileyo ezithimba iliso kwaye zime kuvavanyo lwexesha.
