Intshayelelo:

Kushicilelo lwe-multicolor offset, umgangatho wombala woshicilelo uxhomekeke kwinani lezinto zolawulo, enye yazo kukulandelelana kombala woshicilelo.Ngoko ke, kubaluleke kakhulu ukukhetha ukulandelelana kombala ochanekileyo wokushicilela umgangatho wombala.Ukulungelelaniswa okusengqiqweni kolandelelwano lwemibala kuya kwenza umbala wombhalo usondele ngakumbi kumbhalo-ngqangi wokuqala.Eli phepha lichaza ngokufutshane impembelelo yoshicilelo lolandelelwano lombala kumgangatho wombala wento eprintiweyo.Ukwenzela ireferensi yakho kuphela :

Ukulandelelana kombala wokushicilela

Ukulandelelana kombala woshicilelo kubhekiselele kumyalelo woshicilelo lwe-monochrome kushicilelo olunemibala emininzi.Umzekelo, umshicileli wemibala emine okanye umshicileli wemibala emibini uchatshazelwa ngokulandelelana kombala.Ngokuqhelekileyo, kukusetyenziswa kokuhlelwa kolandelelwano lwemibala eyahlukeneyo ekushicileleni, iziphumo zokuprinta zahlukile, ngamanye amaxesha ukucwangciswa kombala wokushicilela kumisela ubuhle bombandela oshicilelweyo okanye hayi.

01 Ubudlelwane phakathi komatshini wokushicilela kunye nolandelelwano lombala Inombolo yombala womatshini wokushicilela kufuneka ithathelwe ingqalelo xa ukhetha ukulandelelana kombala wokushicilela.Oomatshini bokushicilela abahlukeneyo kufuneka basetyenziswe ukuprinta ngokulandelelana kwemibala eyahlukeneyo ngenxa yendalo yabo yokusebenza eyahlukileyo.

Umatshini weMonochrome

Umatshini weMonochrome ungowoshicilelo olumanzi.Iphepha phakathi kombala woshicilelo kulula ukuba zandiswe kwaye zikhubazeke, ngoko ke ushicilelo lokuqala jikelele ukuchaneka overprinter iimfuno ezityheli nomnyama, de iphepha ithande ukuba uzinzile kwaye ushicilelo umbala ukuprintwa.Xa umbala wokuqala wokushicilela womile, umthamo wokudlulisa inki ungaphezulu kwama-80%.Ukuze unciphise ukuhluka kombala kwi-overprinter, vala umbala obalulekileyo kumfanekiso, kufuneka uqale uprinte ithoni ephambili.

Umatshini wemibala emibini

Imibala e-1-2 kunye ne-3-4 yomatshini wemibala emibini yeyomatshini wokushicilela omanzi owomileyo, ngelixa umbala wesibini nowesithathu ungowoshicilelo olumanzi.Ulandelelwano lombala olulandelayo lusetyenziswa ngokubanzi ekushicileleni: 1-2 umbala wokushicilela i-magenta - i-cyan okanye i-cyan - i-magenta;3-4 umbala woshicilelo omnyama-tyheli okanye omthubi-mnyama.

Umatshini weMulticolor

Umatshini onemibala emininzi yoshicilelo olumanzi loshicilelo olufuna ukuba i-inki nganye ichaneke kushicilelo olugqithileyo ngoko nangoko, kwaye kuxinzelelo lwe-inki yoshicilelo olungaphezulu, ayinakuba yi-inki enye kwindawo yoshicilelo “yisuse”.Kwimeko yokushicilela ngokwenene, umbala wokuqala we-inki kwi-overprinting yombala wesibini, umbala wesithathu kunye nombala wesine, ngokulandelayo, inxalenye ye-inki inamathele kwingubo, ukuze ingubo yesine yombala ngokucacileyo ibonise ezine- umfanekiso wombala.I-inki yombala wesi-3 ibambelela ngaphantsi, kuphela i-inki yombala wesi-4 igcinwe nge-100%.

02 Ubudlelwane phakathi kweempawu ze-inki kunye nokulandelelana kombala

Iimpawu ze-inki kunye nokulandelelana kombala

Ekukhetheni ukulandelelana kombala (ngokukodwa ukuprintwa kwe-multicolor), ukuqwalasela iimpawu ze-inki: i-viscosity ye-inki, ubukhulu befilimu ye-inki, ukukhanya, ukomisa, njl.

Viscosity

I-viscosity ye-inki idlala indima ecacileyo kwi-overprinting.Ekukhetheni kufuneka ibe yi-liquidity encinci, i-viscosity ye-inki enkulu ngaphambili.Ukuba akukho ngqalelo ye-inki viscosity iya kwenzeka "reverse overprint" isenzeko, kuya kukhokelela kutshintsho lombala we-inki, okukhokelela kumfanekiso omfiliba, umbala ongwevu, ukusilela.

Ubukhulu be-inki ye-inki emine jikelele ye-viscosity imnyama> eluhlaza> i-magenta > i-yellow, ngoko ke umatshini wemibala emine ngokubanzi usebenzisa "i-black cyan - i-magenta - i-yellow" ukulandelelana kombala woshicilelo, ukwandisa ukukhawuleza kokushicilela.

Ubukhulu befilimu ye-inki

Ubukhulu befilimu ye-inki yinto ephambili yokufezekisa ukucuthwa okungcono kwamanqanaba ombala wokushicilela.Ifilimu ye-inki ibhityile kakhulu, i-inki ayikwazi ukugubungela ngokulinganayo iphepha, ukushicilela isikrini sokukhanya, umbala uthande ukuba nzulu, ufifi;Ifilimu ye-inki ingqindilili kakhulu, kulula ukubangela ukunyuka kwe-mesh point, inguqulo yokuncamathisela, i-layer depressing.

Ngokubanzi, ukhetho lokunyusa ifilimu ye-inki ubukhulu bokulandelelana kombala wokushicilela, oko kukuthi "omnyama - oluhlaza - i-magenta - ephuzi" ukuprinta, umphumo wokushicilela ungcono.

Ukungafihli

Ukucaca kwe-inki kuxhomekeke kumahluko kwisalathiso se-refractive ye-pigments kunye nezibophelelo.Diaphaneity of inki emva overprinting impembelelo umbala mkhulu, njengoko emva overprinting umbala overprinting akukho lula ukubonisa umbala ochanekileyo;Ubuninzi be-inki ecace kakhulu - ukuprintwa kombala, okokuqala ukuprinta ukukhanya kombala we-inki nge-inki yoshicilelo lwamva, ukuphumeza umphumo ongcono wokuxuba umbala.Ke ngoko, ukungafihli kakuhle kwe-inki kuqala, ukukhanya okuphezulu kwe-inki emva kokushicilelwa.

Yomile

Ukusuka kwi-inki yokomisa ukuqwalasela, ukuze wenze umbala we-inki yoshicilelo uqaqambe, iglosi ibe nesiphumo esihle soshicilelo, unokushicilela i-inki ecothayo eyomileyo yoshicilelo kuqala, uprinte isantya sokumisa i-inki kamva.

03 Ubudlelwane phakathi kweempawu zephepha kunye nokulandelelana kombala

Iimpawu zephepha zichaphazela ngokuthe ngqo umgangatho wezinto eziprintiweyo.Ngaphambi kokushicilela, iphepha ikakhulu liqwalasela ukugudiswa, ukuqina, ukuguqulwa, njl.

Ukuguda

Ukugudiswa okuphezulu kwephepha, ukuprintwa kukunxibelelana ngokusondeleyo nengubo, kunokuprintwa ngombala ofanayo, umfanekiso ocacileyo wemveliso.Kwaye ukuguda okuphantsi kwephepha, ushicilelo ngenxa yomphezulu ongalinganiyo wephepha, ukuhanjiswa kweinki kuya kuchaphazeleka, okukhokelela ekushicileleni ifilimu ye-inki ubukhulu, intsimi yomfanekiso inxalenye ye-inki ehambelanayo yehla.Ke ngoko, xa ukuguda kwephepha kusezantsi, i-pigment granule inki erhabaxa kumbala wokuqala.

Ukuqina

Ukuqina kwephepha kunye nokuguda kwephepha kuhambelana ngokusondeleyo.Ngokubanzi, ukugudiswa kwephepha kunye nokwanda kokuqina kwephepha kunye nokuphucula.Ukuqina okuphezulu, ukuguda okuhle kwephepha ngaphambi kokushicilela umbala omnyama, emva kombala okhanyayo wokushicilela;Ngokuchasene noko, umbala wokukhanya wokushicilela wokuqala (ophuzi), emva kombala omnyama, oku kungenxa ye-inki etyheli inokugubungela uboya bephepha kunye nomgubo kunye nezinye iziphene zephepha.

Utshintsho

Ngethuba lenkqubo yokushicilela, iphepha liya kuphazamiseka kwaye landiswe kwinqanaba elithile ngokusebenzisa i-roller rolling kunye nomphumo wombane ojikelezayo, obopheleleke ukuba uthintele ukuchaneka kokushicilela ukuprinta.Ke ngoko, kufuneka uqale uprinte indawo yombala omncinci okanye uguqulelo olumnyama, kwaye emva koko uprinte indawo yenguqulelo yombala omkhulu okanye inguqulelo yombala okhanyayo.

04 Ukulandelelana kombala okhethekileyo weprints ezikhethekileyo

Ekushicileleni nasekuveliseni imisebenzi ekhethekileyo yasekuqaleni, ukulandelelana kombala wokushicilela kudlala indima efihlakeleyo, engakwaziyo ukwenza umsebenzi wokushicilela usondele okanye ubuyisele i-original, kodwa iphinde iphinde ivelise umtsalane wobugcisa boqobo.

Umbala wokuqala

Umbhalo-ngqangi wantlandlolo usisiseko sokwenza iipleyiti kunye nokushicilela.Umbhalo wesandla wombala ngokubanzi unethoni ephambili kunye nethoni esezantsi.Kwimibala ephambili, kukho imibala epholileyo (eluhlaza, eluhlaza okwesibhakabhaka, emfusa, njl.) kunye nemibala efudumeleyo (ephuzi, i-orange, ebomvu, njl.).Ekukhethweni komyalelo wombala, kufuneka ulandele umgaqo weprayimari kunye nesekondari.Ngoko ke, kwilungiselelo lokulandelelana kombala, kunye nemibala efudumeleyo ngokuyinhloko eprintiweyo emnyama, eluhlaza, ebomvu, ephuzi;Ukupholisa umbala - ushicilelo olusekelwe obomvu, emva kokushicilela okuluhlaza.Ukuba ithoni ephambili yomzobo we-landscape ngumbala opholileyo, ukulandelelana kombala kufuneka kufakwe kwi-plate eluhlaza kamva okanye ukushicilelwa kokugqibela;Kwaye ithoni ephambili yomzobo womzobo wombala ofudumeleyo, kwi-magenta, kufuneka ifakwe kwi-magenta version kamva okanye ukuprintwa kokugqibela, ukwenzela ukuba ithoni ephambili ibe malunga nomfanekiso ugxininisa umxholo.Kwakhona, ithoni ephambili yomzobo wendabuko waseTshayina kumnyama, omnyama kufuneka afakwe emva kwexesha okanye ekugqibeleni ukushicilelwa.
