Logama nje i-R+G+B imibala emithathu ingqubana ngokomlinganiselo, ngaphezulu kweshumi lezigidi zemibala inokuveliswa.Kutheni umnyama?Umnyama unokuveliswa xa umlinganiselo we-RGB ulingana, kodwa kuthatha ii-ink ezintathu ukuvelisa umbala omnye, ongenakwenzeka kwimbono yezoqoqosho.Enyanisweni, umnyama usetyenziswa kakhulu kwinkqubo yoyilo, eyona nto ibangela ukuba kuprintwe imibala emine.Kukho enye inqaku: xa umnyama oveliswe yi-RGB uthelekiswa nomnyama oxutywe ngokuthe ngqo nge-inki, owokuqala unombono ongento, ngelixa umva uziva unzima.
1. Ngomgaqo wemibala emine, kulula kakhulu ukuba wonke umntu amkele.Ilingana neefilimu ezine ngexesha lokuphuma, kwaye ikwalingana neziteshi ezine ze-cyan, i-magenta, i-yellow, kunye nomnyama (C, M, Y, K) kwiitshaneli kwi-PHOTOSHOP.Ukuguqulwa kwetshaneli xa siqhuba umfanekiso ngokwenene lutshintsho kwifilimu.
2. Iminatha, amachaphaza kunye neekona, inetha ezisicaba kunye neminatha ejingayo.Umnatha: nge-intshi nganye yesikwere, inani lamachaphaza abekiweyo, i-175 i-mesh kwizinto eziqhelekileyo eziprintiweyo, kunye nama-mesh angama-60 ukuya kwi-100 ye-mesh yephephandaba, ngokuxhomekeke kumgangatho wephepha.Ukuprintwa okukhethekileyo kunama-meshes akhethekileyo, kuxhomekeke kwi-texture.
1. Ubume kunye nokuchaneka komfanekiso
Ushicilelo lwale mihla lweoffset lusebenzisa ushicilelo lweoffset (ukushicilela ngemibala emine ngokugqithisileyo), oko kukuthi, umfanekiso wombala wahlulwe ube yimibala emine: cyan (C), imveliso (M), emthubi (Y), emnyama (B) ifilimu enamachaphaza emibala emine, kwaye emva koko uprinte I-PS plate iprintwa kane ngumatshini we-offset, kwaye yimveliso eprintiweyo ngombala.
Imifanekiso yoshicilelo yahlukile kwimifanekiso yesiqhelo yokubonisa ikhompyutha.Imifanekiso mayibe kwimo yeCMYK endaweni yeRGB okanye ezinye iindlela.Xa ukhupha, umfanekiso uguqulwa ube ngamachaphaza, nto leyo echanekileyo: dpi.Ubuncinci obuncinci bokuchaneka kwemifanekiso yoshicilelo kufuneka ifikelele kwi-300dpi/pixel/intshi, kunye nemifanekiso emihle odla ngokuyibona ekhompyutheni idla ngokuziva intle kakhulu kwimonitha.Ngapha koko, uninzi lwazo ziifoto zemowudi ye-72dpi RGB, kwaye uninzi lwazo alunakusetyenziselwa ukuprinta.Imifanekiso esetyenzisiweyo akufuneki iboniswe njengomgangatho.Sukucinga ukuba imifanekiso ingasetyenziselwa ukuprinta kuba ilungile nge-acdsee okanye enye isoftware, kwaye ilungile emva kokwandiswa.Kufuneka zivulwe kwi-photoshop, kwaye ubungakanani bomfanekiso busetyenziselwa ukuqinisekisa ubunyani.Ukuchaneka.Umzekelo: umfanekiso kunye nesisombululo se-600 * 600dpi / pixel / intshi, ngoko ubungakanani balo bangoku bunokwandiswa ngaphezu kokuphindwe kabini kwaye lusetyenziswe ngaphandle kwengxaki.Ukuba isisombululo si-300 * 300dpi, ngoko sinokuncitshiswa kuphela okanye ubungakanani bokuqala abunakwandiswa.Ukuba isisombululo somfanekiso ngu-72 * 72dpi / pixel / intshi, ngoko ubungakanani bayo kufuneka buncitshiswe (ukuchaneka kwe-dpi kuya kuba kukhulu), de isisombululo sibe yi-300 * 300dpi, ingasetyenziswa.(Xa usebenzisa lo msebenzi, seta into ethi "Phinda uchaze iPixel" kukhetho lobungakanani bomfanekiso kwiPhotoshop ukuya nanye.)
Iifomati zomfanekiso eziqhelekileyo zezi: TIF, JPG, PCD, PSD, PCX, EPS, GIF, BMP, njl. Xa uyilo, umbala weTIF, i-bitmap emnyama namhlophe, iVector yeEPS okanye iJPG
2. Umbala womfanekiso
Ngokumalunga namagama athile ochwephesha anje ngoshicilelo olungaphezulu, ukuprinta ngokugqithisileyo, ukugoba, kunye nombala wamabala ekushicileleni, ungabhekisa kwezinye iziseko zoshicilelo ezinxulumeneyo.Nazi nje ingqiqo eqhelekileyo ekufuneka inikwe ingqwalasela.
1, umngxuma ngaphandle
Kukho umgca weempawu eziluhlaza okwesibhakabhaka ezicinezelwe kwipleyiti esezantsi etyheli, ngoko ke kwipleyiti etyheli yefilimu, indawo yabalinganiswa abaluhlaza kufuneka ingabi nanto.Okuchaseneyo kukwayinyaniso kwinguqulelo eluhlaza okwesibhakabhaka, ngaphandle koko into eluhlaza okwesibhakabhaka iya kuprintwa ngokuthe ngqo kumthubi, umbala uya kutshintsha, kwaye umlingiswa oluhlaza okwesibhakabhaka uya kuba luhlaza.
2. Ushicilelo olungaphezulu
Kukho umgca weempawu ezimnyama ezicinezelwe kwipleyiti ethile ebomvu, ngoko indawo yabalinganiswa abamnyama kwi-plate ebomvu yefilimu akufanele ikhutshwe.Ngenxa yokuba umnyama unokubamba phantsi nawuphi na umbala, ukuba umxholo omnyama uvaliwe, ngokukodwa umbhalo omncinci, impazamo encinci yokushicilela iya kubangela ukuba umgca omhlophe ubonakale, kwaye umehluko omnyama nomhlophe mkhulu, kulula ukuyibona.
3. Imibala emine emnyama
Oku kukwayingxaki eqhelekileyo.Phambi kokukhupha, kufuneka ujonge ukuba umbhalo omnyama kwifayile yopapasho, ngakumbi ushicilelo oluncinane, lukwipleyiti emnyama kuphela, kwaye akufuneki luvele kwamanye amacwecwe anemibala emithathu.Ukuba kubonakala, umgangatho wemveliso eprintiweyo uya kuthotywa.Xa imizobo ye-RGB iguqulelwa kwimizobo ye-CMYK, umbhalo omnyama ngokuqinisekileyo uya kuba mnyama ngemibala emine.Ngaphandle kokuba kuchazwe ngenye indlela, kufuneka iqwalaselwe phambi kokuba ifilimu ikhutshwe.
4. Umfanekiso ukwimowudi yeRGB
Xa ukhupha imifanekiso kwimo ye-RGB, inkqubo ye-RIP iyaziguqulela ngokuzenzekelayo kwimowudi ye-CMYK yemveliso.Nangona kunjalo, umgangatho wombala uya kuncitshiswa kakhulu, kwaye imveliso eprintiweyo iya kuba nombala okhanyayo, ungakhanyi, kwaye umphumo ubi kakhulu.Umfanekiso uguqulelwe kakuhle kwimodi ye-CMYK kwi-photoshop.Ukuba ngumbhalo-ngqangi oskeniweyo, kufuneka udlule kwinkqubo yokulungiswa kombala ngaphambi kokuba umfanekiso usetyenziswe.
