Ukuprintwa kwesikrini kuvelisa ukuphambuka kombala ngenxa yezi zinto

Kutheni ukuprinta kwesikrini kuvelisa imibala enemibala? Ukuba sibeka ecaleni umxube wemibala eliqela size siqwalasele umbala omnye kuphela, kunokuba lula ukuxoxa ngezizathu zokuprinta umbala. Eli nqaku labelana ngezinto ezininzi ezichaphazela ukuphambuka kombala ekuprinteni kwesikrini. Umxholo ungowokubhekiswa kubahlobo abathenga kwaye banikezela ngenkqubo yezinto zokupakisha zeYoupin:

Apha ngezantsi kukho ezinye zezinto eziqhelekileyo ezibangela ukuphambuka kombala ekuprintweni kwesikrini: ukulungiswa kwe-inki, ukukhethwa kwe-mesh, uxinzelelo lwe-mesh, uxinzelelo, ukomisa, iimpawu ze-substrate, iimeko zokujonga, njl.

 

01 Ukulungiswa kwe-inki
Ukuxuba i-inki Xa sicinga ukuba i-pigment ye-inki esetyenzisiweyo yi-pigment eqhelekileyo, eyona nto ibangela ukuphambuka kombala kukongeza izinyibilikisi ezifana ne-inki yokuxuba i-oyile kwi-inki. Kwi-workshop enezixhobo ezilungileyo zokulawula umbala, i-inki inokuxutywa ngokwezixhobo zokulawula. Nangona kunjalo, kwiinkampani ezininzi zokuprinta, akunakwenzeka ukuba nezi zixhobo. Baxhomekeke kuphela kumava abasebenzi abangoochwephesha xa bexuba i-inki.

Ngokubanzi, ioyile yokulungisa i-inki yongezwa ukuze i-inki ifaneleke ngakumbi xa iprintwa. Nangona kunjalo, xa i-oyile yokulungisa ifakiwe kwi-inki, ubuninzi beepigment kwi-inki buya kutshintsha, nto leyo eya kukhokelela kutshintsho kwiimpawu zombala we-inki ngexesha lokuprinta. Ukongeza, isinyibilikisi esigqithisileyo kwi-inki siya kwenza ifilimu encinci ye-inki emva kokuba yomile, nto leyo eya kunciphisa ukukhanya kombala.

Kukwakho nengxaki yokuba i-inki ixutywe ngaphambi kokuba ixutywe. Umzekelo, abasebenzi kwivenkile ye-inki benza izigqibo ngokusekelwe kwifomyula yabo xa bexuba okanye bexuba i-inki. Oku kukhokelela ekuphambukeni kombala okungenakuphepheka. Ukuba i-inki ixutywe kwiintsuku ezimbalwa ezidlulileyo, Ukuba uprinta nge-inki elungileyo, umbala obangelwa yile meko uya kucaca ngakumbi. Ke ngoko, phantse akunakwenzeka ukuba ungayiphephe ngokupheleleyo umbala oxutywe.

 

02 Ukukhetha i-Mesh
Ukuba ucinga ukuba ubungakanani be-mesh yesikrini kuphela kwento echaphazela ukudluliselwa kwe-inki, uya kudibana neengxaki ezininzi. Ububanzi be-mesh kunye nemibimbi nazo zichaphazela ukudluliselwa kwe-inki. Ngokubanzi, i-inki eninzi inamathele kwimingxuma ye-inki yesikrini, i-inki eninzi iya kudluliselwa kwi-substrate ngexesha lenkqubo yokuprinta.

Ukuze kuqikelelwe kwangaphambili ukuba ingakanani i-inki enokudluliselwa yi-mesh nganye, ababoneleli abaninzi besikrini banikezela nge-volume ye-inki yokudlulisa i-inki (TIV) ye-mesh nganye. I-TIV yiparameter ebonisa ubungakanani be-inki yokudlulisa isikrini. Ibhekisa kwinani le-inki edluliselweyo kwindawo ethile. Ingakanani i-inki eya kudluliselwa yi-mesh nganye phantsi kweemeko ezithile zokuprinta. Iyunithi yayo yivolumu ye-inki kwindawo nganye yeyunithi.

Ukuqinisekisa ukuba ithoni iyafana xa kuprintwa, akwanelanga ukugcina inani le-mesh yesikrini lingatshintshi, kodwa nokuqinisekisa ukuba ububanzi besikrini kunye nokugungqa kwaso kuhlala kungaguquki. Utshintsho kuyo nayiphi na iparameter yesikrini luya kubangela utshintsho kubukhulu befilimu ye-inki ngexesha lokuprinta, nto leyo ekhokelela kutshintsho lombala.

 

03 Uxinzelelo olupheleleyo
Ukuba uxinezeleko lwenethi luncinci kakhulu, luya kubangela ukuba ifilimu ixobuke. Ukuba kukho i-inki eninzi ehlala kwi-mesh, into eprintiweyo iya kuba mdaka.

Le ngxaki ingasombululwa ngokwandisa umgama phakathi kwesikrini kunye ne-substrate. Nangona kunjalo, ukwandisa umgama phakathi kwesikrini kunye ne-substrate kufuna ukwandisa uxinzelelo, oluya kubangela ukuba i-inki engaphezulu idluliselwe kwi-substrate. ukutshintsha uxinano lombala. Eyona ndlela ilungileyo kukugcina uxinzelelo lwe-stretch net lufana, ukuqinisekisa ukuhambelana kombala.

 

04 Inqanaba loxinzelelo
Useto olufanelekileyo loxinzelelo lubalulekile ekugcineni umbala ungaguquguquki, kwaye ukuqinisekisa ukuba amanqanaba oxinzelelo afanayo ngexesha lenkqubo yokuprinta kubalulekile. Ingakumbi kwimisebenzi yokuprinta ephezulu nephindaphindwayo.

Xa kufikwa kuxinzelelo, into yokuqala ekufuneka uyiqwalasele bubunzima be-squeegee. Ubulukhuni be-squeegee buncinci, nto leyo ilungele izinga lokudibana, kodwa ayilungelanga ukumelana nokugoba. Ukuba ubulukhuni buphezulu kakhulu, ukungqubana kwesikrini kuya kuba kukhulu ngexesha lokuprinta, nto leyo echaphazela ukuchaneka kokuprinta. Okwesibini yi-engile ye-squeegee kunye nesantya se-squeegee. I-engile yemela ye-inki inempembelelo enkulu kubungakanani bokudluliselwa kwe-inki. Okukhona i-engile yemela ye-inki incinci, kokukhona i-engile yemela ye-inki inkulu. Ukuba isantya semela ye-inki sikhawuleza kakhulu, siya kubangela ukugcwaliswa kwe-inki okunganelanga kunye nokuprintwa okungaphelelanga, ngaloo ndlela sichaphazela umgangatho woshicilelo.

Wakuba ufumene useto oluchanekileyo loxinzelelo lomsebenzi wokuprinta kwaye ulurekhode ngokuchanekileyo, lo gama nje ulandela ezi seto ngokuchanekileyo ngexesha lenkqubo yokuprinta, uya kufumana imveliso yoshicilelo eyanelisayo enemibala efanayo.

 

05 owomileyo
Ngamanye amaxesha, umbala ubonakala ungaguquki emva nje kokuprinta, kodwa umbala uyatshintsha emva kokuba imveliso egqityiweyo ifunyenwe. Oku kudla ngokubangelwa kukuseta okungachanekanga kwezixhobo zokomisa. Eyona nto ixhaphakileyo kukuba ubushushu bokomisa bubekwe phezulu kakhulu, nto leyo ebangela ukuba umbala weinki ephepheni okanye kwikhadibhodi utshintshe.

 

06 Iimpawu ze-substrate
Umba omnye abachwephesha bokuprinta kwesikrini abawuhoyiyo ziimpawu zomphezulu we-substrate. Iphepha, ikhadibhodi, iplastiki, njl. zonke ziveliswa ngamanani, kwaye ii-substrate ezisemgangathweni ophezulu zinokuqinisekisa iimpawu zomphezulu ezizinzileyo nezihambelanayo. Kodwa oku akunjalo. Utshintsho oluncinci kwiimpawu zomphezulu we-substrate luya kubangela ukuphambuka kombala ekuprinteni. Nokuba uxinzelelo lokuprinta lufana kwaye inkqubo nganye isebenza ngokuchanekileyo, ukungangqinelani kwiimpawu zomphezulu we-substrate kuya kubangela utshintsho olukhulu lombala ekuprinteni. Umbala otyhidiweyo.

Xa imveliso efanayo iprintwa kwiindawo ezahlukeneyo ezinezixhobo ezifanayo zokuprinta, impembelelo yeempawu zomphezulu we-substrate kumbala iyabonakala ngakumbi. Abathengi banokufuna ukuba iintengiso zefestile ziprintwe kwiplastiki okanye kwenye ikhadibhodi. Kwaye abathengi banokufuna imibala efanayo kwisixhobo esinye.

Kwiimeko ezinje, isisombululo kuphela kukwenza umlinganiselo ochanekileyo wombala. Sebenzisa i-spectrophotometer okanye i-spectral densitometer ukulinganisa uxinano lombala. Ukuba kukho utshintsho lombala, i-densitometer inokukubonakalisa ngokucacileyo, kwaye ungayoyisa le nguqu yombala ngokulawula ezinye iinkqubo.

 

07 Iimeko zokuqwalasela

Amehlo omntu anovelwano kakhulu kutshintsho oluncinci lombala, kwaye anokwahlula imibala kuphela phantsi kweemeko zokukhanya. Ngenxa yesi sizathu, qiniseka ukuba uthelekisa imibala phantsi kweemeko zokukhanya ezifanayo. Ngaphandle koko, ukulungisa umthamo we-inki okanye uxinzelelo kuya kuvelisa i-inki engaphezulu. Umbala omkhulu.

Lilonke, isitshixo sokugcina umbala ungaguquguquki sixhomekeke kulawulo oluzinzileyo lwenkqubo nganye ukuqinisekisa ukusebenza okuzinzileyo kwe-inki. Ukukhethwa kobungakanani be-mesh, uxinzelelo kunye noxinzelelo lwesikrini esoluliweyo, iimpawu zomphezulu we-substrate kunye neemeko zokujonga zonke zinempembelelo ethile ekuphambukeni kombala. Nangona kunjalo, iirekhodi zokuseta ezichanekileyo kunye nolawulo oluzinzileyo lwenkqubo nganye zizitshixo zokuqinisekisa imibala yokuprinta kwesikrini engaguquguqukiyo.
