Yintoni CMYK? Zine halftone umbala (okwengca, kunye Bomvu Mthubi, umbala Key). CMYK and RGB

Abaninzi baye baliva CMYK basisishunqulelo, esetyenziswa baprintayo, kodwa andazi ukuba njani buzimisile. Ukuze uqonde ukuba yintoni na imibala ezine zimela ezo leta kwaye yintoni iimpawu oko autotype ukunceda inqaku lethu.

Xa umhlaba ukukhohlisa nabizayo

Ngaphambi sifumanisa oko CMYK, kufuneka siyiqonde imo yendalo ummangaliso onjalo, ngathi ukukhanya bendalo. Bambalwa abantu bacinga ukuba umbala ikhona kuphela ngaphakathi kwinkqubo, ezo amacandelo efunekayo ababukeli, ukukhanyisa, izinto. Kule imimangaliso ezamehlo musa iphele khona. Umzekelo, nangona ukukhanya qwa esikubona njenge enemibala emihle, oko iqulethe yonke imibala spectrum ibonakale emehlweni oluntu. Kunika naye umbala zifundo multicomponent. Xa ukukhanya emhlophe egqitha sifundo, likumyinge nokuba iimpahla zazo, ethintela imibala ezithile. Xa ababesele kubonakala kwaye udale ku kumbonisi kwimbono womfanekiso ukuba liphelelwe okanye eqaqambileyo.

Veliswa lwesicatshulwa kunye nemifanekiso kwimidiya ebonakalayo ukusuka kwindawo umbono okuqonda kwabantu

Iphepha kuyo ushicilelo rhoqo omhlophe ekuqaleni kwaye uyakwazi ukumela nobubanzi obuzeleyo imibala kwelanga, apho uwe. I ngcono umgangatho, kungona iipropati kumphezulu vangama. Kwangaxeshanye, idayi - into elenza imibala ethile. Ukuba oko kuya kulibazisa imitha onke amabanga ngaphandle kwabo ezihambelana icandelo ebomvu spectrum, le ndoda kwelanga ubona kuphela yidayi. Xa sijonga lo mbala enye ngokuvutha kwesibane emsi, oko kuya kubonakala ngathi abamnyama.

Xa iphepha elimhlophe iyasetyenziswa imibala eyahlukeneyo, ukucutha ubuninzi imibala ziboniswe. Umzekelo, ngokusebenzisa iphepha ngombala oluhlaza, siyakubonga ukudala imeko apho akukho nje ngokubamba kuphela.

Kukho izayamaniso imibala, xa ixutywe engafumaneka Ipeyinti, ukukwazi ukuba ufunxe ngokupheleleyo zonke imitha kuboniswe iphepha, oko kukuthi. E. Ukwenza kube abamnyama. Ngokukodwa, kwanele ukuba asebenzise isixa efanayo magenta, oluhlaza kunye zombala ezityheli.

Kufuneka kuqatshelwe ukuba le modeli umbala akadingi ipeyinti emhlophe, njengoko oku umbala zephepha ngokwayo. Ngaloo iindawo umfanekiso apho afuneka khona, akukho zombala nje ukuba isicelo, eshiya phezu uhlambulukile.

imodeli yeyeemeko apho

Iphepha kunye nezinye izinto ezishicilelweyo - na ocinga ukuba uyakwazi ukubonakalisa ukukhanya nobushushu bendalo okanye ngumntu. Ngokucacileyo, kuya kuba lula ngakumbi ukuba ukubala, lingakanani ngayo ngohlobo semitha zatshintsha lwayo olungaphesheya kunokuba ukufunxa ngayo. Ngoko ke, ukuba sisuswe 3 imibala yokuqala amhlophe, okt. Amacandelo E. Basic RGB, kuya umGangatho imibala edibanayo CMY.

Kutheni «K», endaweni «B»

Ngokuqhelekileyo abo bangazazanga na CMYK, esi shunqulelo into edidayo. Ngapha koko, njengokuba kuthiwe, le modeli umbala usebenzisa ngombala ezahlukeneyo 4. Ezintathu zazo babizwa incwadi yawo yokuqala. Ukongeza, kusetyenziswa emnyama. Enye inguqulelo ithi K - segama elithi IsiNgesi omnyama. Kuye izakusetyenziswa endaweni "kwi" ebhekisela kumntu omnyama ifilimu baprintayo, kungekhona ukuba bedidekile kunye okufanayo ngeleta yemodeli RGB (Eng. Blue). Isibakala sokuba correctors umbala professional ilawulwe Itshaneli RGB_CMYK_Lab 10 kwaye usebenzise zonke izithuba umbala ezikhoyo. Ngenxa yoko, xa usebenzisa segama le-autotype ezine, ibinzana elithi 'inyathelo umjelo B »kuya kufuna ukucaciswa kuyo nayiphi na onobuhle umbuzo, bekuya kuba nzinyana.

Kukho enye imboniselo. Ngokutsho oluguqulelo, «K» - segama elithi "isitshixo", okt kwipleyiti iqhosha ... Bayibiza ifomu eshicilelweyo inki emnyama oluthi lusetyenziswe phezu sele edla ezintathu ebala yangaphambili.

Ukongeza, ezinye iingcali oyikholelwayo ukuba i "K" yeyona pronunciation German kunye nentsingiselo kontur ilizwi. Xa ubabalo kwefom entsha kukuba yemveli abamnyama umboniso kweli shishini wokushicilela ebizwa ithambeka.

Njani na athi in Russian

Nangona imodeli umbala CMYK iye isetyenziswe ixesha elide, abantu abaninzi abazi unanamhla indlela isandi le segama. Iingcali ukucebisa ukuba bathi ngokuvakalayo, njengoko "C-Em-Wye Kay." Ukongeza, kukho iingcebiso kubizwa ngokuba umbala-4 avotipiyu "B-Mac", kwakunye ukusebenzisa igama elithi "umbala ngokupheleleyo" okanye "inkqubo inks".

RGB, CMYK: yintoni umahluko

Ukuba CMYK scheme lisetyenziswa ishishini wokushicilela, imodeli bomvu-luhlaza-blowu isetyenziswa ukuze zixhonywe kwi TV, esweni kunye nokunye okuboniswayo. Njengoko siyazi? ayimiqulu pixels ezo amachaphaza amancinci, nganye eneyazo a ilayithi 3, kuxhomekeke nokuqaqamba nganye kusibonisa umthunzi olufunwayo umbala.

Xa umfanekiso ishicilelwa ukususela computer, umshicileli okanye offset ukwenza oku besebenzisa imibala CMYK (umbala oluhlaza, magenta, mthubi, umbala key). Ngoko ke, ukubukela umfanekiso in RGB nkqubo zinokwahluka kakhulu kwindlela ukufumana ephepheni okanye enye into ebambekayo.

Isizathu sokuba indlela yokudlulisa umfanekiso ukusuka umbala omnye komnye zeesekethe apho nje awukwazi ukunika nekhulu hit ekhulwini. Eneneni, imibala ezininzi RGB bamane ayisekho kwaye ayikwazi kwenziwa ngendlela CMYK Ebiziweyopalette (nayiphi na umbala ngundoqo kule nkqubo, sele ukwazi). Bona indawo kunye nombala ekufutshane, kodwa umahluko xesja zisabonakala kakhulu ukuba ngeliso lenyama.

Kutheni le CMYK imibala-4, kunye RGB ezi-3 kuphela

Njengoko usazi, i-inki emnyama nibe senilungile ngokuxuba magenta, omthubi, oluhlaza, ubanjisiwe olinganise ngokulinganayo. Noko ke, ngenxa ezinye izizathu kufuneka sisebenzise i ngombala olongezelelweyo. Isizathu sokuba-autotype amane ibandakanya ukusetyenziswa ngesithambiso esimnyama, nje ezimbalwa. Phakathi kwabo:

• umxube omthubi, magenta kunye umbala oluhlaza ngombala, xa kusenziwa, ukwenza i umbala emdaka emdaka ;
• inkqubo inks aluboneleli Ukuzinza nombala Ukwanda kunye neendawo izimvi yomfanekiso;
• xa kukukhupha namalungu amancinane kakhulu abamnyama zetekisi okanye ipateni ngaphandle kokusebenzisa mbala loo kwandisa umngcipheko kuqondana ngokwaneleyo ngqo lamanqaku isicelo of umbala oluhlaza, magenta kunye imibala etyheli;
• sombala omnyama (njenge eqhelekileyo carbon black) kutshiphu kakhulu kunabanye ipeyinti;
• Ukuxutywa ka 100% etyheli, magenta okanye oluhlaza ngombala kwindawo enye kwimeko inkjet ngokwaneleyo wets ngamandla iphepha, oko deforms kwaye yandisa ixesha elifunekayo okusula.

uhlobo yokugqibela iingxaki ezinokuvela kule nkqubo offset. Ukongeza, ngokuxhomekeke kwisixhobo eso? Kukho imiqathango ethile kwisixa yepeyinti. Kwezinye abashicileli, kusenokuba nokuba ibe inkulu kakhulu kwaye ukufikelela 260-280%. Oku kuthetha ukuba abamnyama "yokwenene" kwizixhobo kushicilelo enjalo elungiswe ngokuxuba zombala akunakwenzeka. Ngoko ke, esebenzisa omnye ngesithambiso esimnyama.

Yintoni CMYK-print

Xa yokuprinta okanye yoshicilelo isilika-screen kwi umatshini offset, umbala laser printer, njalo njalo. E. Kuyenzeka ngaxa nganye, okanye sebenzisa i ubukhulu inki umaleko ethile, okanye shiya zeendawana lomelele kwaye licocekile. Ngenxa yoko, yokudlulisela umfanekiso halftone rasterized. Ngamanye amazwi, kuba uchazwa iseti amachaphaza imibala emine. Ukuxinana ukubeka yabo kugqiba yipesenti ukusetyenziswa nganye imibala. Ngelo umgama ukusuka eliphakathi ngokwasemzimbeni (iphepha, ifilim, njl) Le iingongoma kufutshane omnye komnye, hlanganisa, kwaye Iliso lomntu ubona nombala oyifunayo. RIP ngu:

• awo xa inani amanqaku rhoqo, kodwa iyahluka ubungakanani;
• stochastic xa kungekho isakhiwo indawo rhoqo;
• rhoqo, nto leyo ebonisa ubungakanani yolondolozo xa utshintsha ubungakanani lamanqaku.

Njani ukuba kudana xa uprinte iifoto kwi umshicileli

Namhlanje, abashicileli sele ezindlini ezininzi. Bona zisetyenziselwa ukulungiselela wasekhaya, ukubhala amaphepha elide, izincoko, njalo njalo. Njalo kakhulu, umshicileli uzame uprinte iifoto. Noko ke, ngokokuqhelekileyo ezo nzame ziphela ukuphoxeka kuba umfanekiso eliqaqambileyo kwikhusi luthe kuncipha kwi ikopi ephepheni. Zonke umcimbi ukuguqulelwa nomfanekiso RGB ukuba CMYK imodeli model.

Ukuze ubone indlela ifoto tlakukeke ephepheni, ungasebenzisa inkqubo Adobe Photoshop. Kulo mzekelo, umfanekiso ezinokulungiswa ukuze ufumane isiphumo engcono.

Ngoku uyazi ukuba yintoni na CMYK, le ungayiqondiyo wema kunye neentsilelo oko anako. Kungenzeka, kwixesha elizayo kufuphi endaweni yayo kuphuma umbala phambili ngakumbi eziza kuphucula umgangatho umfanekiso yoshicilelo.
