Waa maxay CMYK? Afar halftone midabka (Cyan, Magenta, Yellow, midabka Key). CMYK iyo RGB

Dad badan oo maqlay gaabiyay CMYK ah, taas oo loo isticmaalayo in industry daabaco, laakiin ma oga sida ay u taagan tahay. In la fahmo waxa ay afar midabo kala matalaan kuwa waraaqaha iyo wixii guryaha waxaa autotype caawin our article.

In dunida of uunu u indhaha

Ka hor inta aan ogaado waxa CMYK ah, waa in aad fahamtaa nooca mucjiso noocan oo kale ah, sida iftiinka dabiiciga ah. Dad yar qabaa midab kalana kaliya nidaamka, kuwaas oo ka kooban muhiim ah oo ka mid ah daawadayaasha, nalalka iyo waxyaabaha. In this mucjisooyinka indhaha ma waxaa loo soo afjaro. Tusaale ahaan, in kasta oo iftiin cad oo saafi ah waannu og nahay sida midab ah, waxa ku jira oo dhan midabada spectrum ee la arki karo in ay indhaha aadanaha. Waxaa isaga ku siinayaa midabka maadooyinka multicomponent. Marka iftiin cad gaadho mawduuca, oo ay dusha loo eegin hantida, nuuga midabyo gaar ah. Marka hadhay muuqata iyo in la abuuro in aragtida siladda ee image ah in la yaraaday ama dhalaalaya.

Dhalmada ee qoraalka iyo images on warbaahinta jirka ka barta of view of aragtida aadanaha

Wargeyska ayaa on taas oo daabacaadda inta badan waa hore caddaan iyo karti uu u leeyahay si ay u matalaan qaybaha kala buuxda ee midabada iftiinka qoraxda, taas oo ku dhoco. The wanaagsan tayada, sare ee guryaha laga fekerayo dusha. Isla mar ahaantaana, dheeha - walax in nuuga midabyo gaar ah. Haddii ay dib u dhigi doontaa rays oo dhan wavelengths kuwa u dhigma qayb cas ee spectrum mooyee, nin qorraxda arka kaliya dheeh ah. Haddii aynu eegno Midabka isla siyasad laambadda buluug ah, in ay u muuqato inagu madow.

Marka warqada cad waxaa laga dalbadaa midabo kala duwan, yaraynaysaa qadarka midabo ka muuqataa. Tusaale ahaan, by codsanaya warqad Midabka buluuga ah, waxa aan la abuuro xaalad ay waxaa kaliya oo aan u nuuga.

Waxaa jira isku mid ah midabo, markii lagu daray taas oo laga heli karaa rinjiga, awood u leeyahay inuu si buuxda u nuugo oo dhan rays ee ka muuqataa by warqada, in uu yahay. E. Si aad uga dhigto madow. Gaar ahaan, waa ku filan tahay si aad u dalbato lacagta la mid ah magenta, cyan iyo pigments huruud ah.

Waa in la ogaadaa in model midabka this uma baahna rinjiga cad, sida midabka this warqad laftiisa. Meelaha kuwa image ah meesha looga baahan yahay, pigments ma yihiin si fudud ma codsatay, tegaayo dusha ka nadiifisaan.

model subtractive

Paper iyo arrinta kale ee ku daabacan - waa dusha ka tarjumaya karo iftiinka dabiiciga ah ama aan dabiici ahayn. Sida iska cad, waxay u badan habboon in la xisaabiyo, sida badan waxaa ka mid ah in qaab rays inay soo horjeeda ka badan sida ay u nuugo bedelay jihada. Sidaas darteed, haddii laga 3 midabada aasaasiga ah ee cad, qaybaha E. Basic RGB ie. Jaraa, waxa kordhi doonaa saddex jibaar midabada kaabaha CMY.

Maxaad «K», halkii «B»

Sida caadiga ah, kuwa aan ogaado waxa CMYK ah, gaabiyay this waa mid lagu wareerayo. Ka dib oo dhan, sida la sheegay, model midabka this isticmaalaa 4 pigments kala duwan. Sadex ka mid ah waxaa lagu magacaabaa by ay warqad ugu horeysay. Intaa waxaa dheer, waxaa loo isticmaalaa madow. Mid ka mid ah version dhigayaa in K - gaabiyay erayga English madow. Waxa loo adeegsaday halkii "in" si uu u tilmaamo filim madow on warshadaha daabaco, ma aha kuwo lagu wareero oo la isku warqad of model RGB ah (Eng Blue.). Xaqiiqada ah in correctors midabka xirfadeed maasuqay RGB_CMYK_Lab 10 channels oo ay isticmaalaan dhammaan meelaha midabka heli karo. Sidaas darteed, marka la isticmaalayo soo gaabiyay ee afar-autotype, weedha "tallaabada la channel B ah» u baahan tahay caddaynta on mid ka mid ah lagu daydo ee su'aasha, waxa uu noqon lahaa xanibayo.

Waxaa jira aragti kale. Sida laga soo xigtay version this, «K» - gaabiyay erayga "muhiimka ah", ie waslad khafiif ah oo muhiim ah ... Waxay tixraac foomka daabacan oo ah khad madow in waxaa laga codsadaa on top of hore u shubo saddex Midabka hore.

Intaa waxaa dheer, khubarada qaar ka mid ah ay yihiin dhiiran tahay in ay aaminsan yihiin in ay "K" waa ku dhawaaqida Jarmalka iyo macnaha of kontur erayga. In raalli ee version ugu dambeeyay ee waa xaqiiqda ah in filimka madow dhaqanka ganacsiga daabacaadda ee loo yaqaan contouring.

Sidee baad, Ninkanu ee Ruush

Inkastoo model CMYK midabka ayaa loo isticmaali jiray muddo dheer, dad badan ma oga ilaa maantadan la joogo sida inay ka dhawaajiyaan gaabiyay this. Khubarada talin in ay kor u dhahaan, sida "C-EM-Wye Kay." Intaa waxaa dheer, waxaa jira talooyin in loogu yeedho avotipiyu 4-color "B-Mac", iyo sidoo kale in ay isticmaalaan erayga "color full" ama "Daac nidaamka".

RGB, CMYK: Maxay ku kala duwan

Haddii nidaamka CMYK waxaa loo isticmaalaa in ganacsiga daabaco, model ah casaan-cagaaran-buluug ah waxaa loo isticmaalaa bandhigay on telefishinada, kormeerayaasha iyo qaab kale. Sida aan ognahay? waxay ka kooban yihiin pixels kuwaas oo dhibco yar yar, kuwaasoo mid walba uu leeyahay backlight a 3 iyo, iyada oo ku xiran dhalaalka kasta iftiiminaya Hooska doonayo ee midabka.

Marka image waxaa la daabacay ka computer ka, printer ama mowjadda jaraa'id qaban this isticmaalaya midabada CMYK (cyan, magenta, jaalle ah, midabka oo muhiim ah). Sidaa darteed, arkaysid image ee nidaamka RGB la taaban karo kala duwanaan karaan waxa aad ka heli on warqad, ama shey kale oo la taaban karo.

Sababta habka image kala iibsiga ka mid midab in wareeg kale taas oo si fudud aan ku siin kara boqolkiiba boqol hit. Indeed, dad badan oo midabo RGB si fudud aan ka jirin oo aan la fulin karo in CMYK palette ah (key kasta oo midab nidaamka this, aad hore u taqaan). Waxaa loo bedelay cado ugu dhow, laakiin farqiga u weli waa kuwa aan la arki karo xitaa in ay isha oo qaawan.

Waa maxay sababta in CMYK 4 midabada, iyo RGB yihiin kaliya 3

Sida aad ogtahay, khad madow loo diyaar garoobo laga yaabaa in ku khalda magenta, jaalle ah, iyo buluug, qaaday in Joogaba, loo siman yahay. Si kastaba ha ahaatee, qaar ka mid ah sababaha aan u leeyihiin in ay isticmaalaan Midabka dheeraad ah. Sababta sababta Afar-autotype ku lug leedahay isticmaalka rinjiga madow, dhowr ah. Ka mid ah iyaga,

• isku dar ah ee jaalaha ah, magenta iyo cyan pigments, ku dhaqanka, abuuro a color brown wasakh ;
• Daac habka aadan bixin xasiloonida ee u damaysay cado iyo meelaha cirro sanamkii;
• marka outputting a qaybo aad u yar madow ee qoraalka ama hab aan la isticmaalayo Midabka sida kordhiyaa halista ah ee soo beegay waafi saxda ah ee dhibcood ee codsiga of cyan, magenta iyo midabada jaalaha ah;
• Midabka madow (madow carbon caadi caadiga ah) waa wax badan ka jaban tahay rinjiga kale;
• qodan 100% huruud ah, magenta ama Midabka cyan at hal dhibic kaliya in ay dhacdo inkjet ku filan si adag u kaadiyo warqada, waxaa deforms iyo kordhiyaa waqtiga loo baahan yahay qalajiyo.

nooca dambe ee dhibaatooyinka kacayaan habka daabacaada kabayso. Intaa waxaa dheer, taas oo ku xidhan qalabka? Waxaa jira xayiraad gaar ah oo ku saabsan qadarka rinjiga. In madbacadaha qaar ka mid ah, oo waxa uu xitaa noqon karaan kuwo waaweyn iyo kuwo gaaraan 260-280%. Taas macnaheedu waa in madow "dhabta ah" ee qalabka daabacaadda sida diyaariyey ku khalda pigments wax aan macquul aheyn. Sidaa darteed, iyadoo la isticmaalayo rinjiga kale madow.

Waa maxay CMYK-print

Marka daabacaadda ama daabacaadda Xariir-screen on makiinadda mowjadda daabacaadda, printer laser midab, iyo E. sidaas on. Waxaa suurto gal ah ee qodob kasta, ama isticmaal oo dhumucdiisuna waxay gaar ah lakabka khad, ama ka tago substrate ka dhawrsan oo nadiif ah. Sidaa darteed, gudbinta image halftone rasterized. In si kale loo dhigo, waxaa la matalayay sida set oo ah dhibco afar midabo. cufnaanta ee ay meelaynta go'aamiso boqolleyda isticmaalka kasta oo ka mid ah midabo kala ah. Meel fog ka soo dhexdhexaad ah ee jirka (warqad, filim, iwm) The dhibcood in ku dhow midba midka kale, ku milmaan yihiin, iyo isha aadanaha arkaa cado la doonayo. Yahan waa:

• Ilodanimada inayan marka tirada dhibcaha waa joogto, laakiin kala duwan oo ay size,
• stochastic marka ma jirto dhisme hal dhibic si joogto ah;
• inta jeer, soo jeedinaya size ilaalinta halka beddelo xaddiga dhibcood.

Sidee in aan ceeboobin marka aad daabacan photos on printer ah

Maanta, madbacadaha ku jira guryaha badan. Waxay waxaa loo isticmaalaa diyaarinta shaqada guriga, qoraal ahaan waraaqaha dheer, maqaalo, iyo wixii la mid ah. Inta badan, printer ayaa sidoo kale isku dayaan in ay daabacdo sawirada. Si kastaba ha ahaatee, isku day caadiga ah sida dhameystirka niyad sababtoo ah sawirka dhalaalaya shaashadda noqdo yaraaday in koobiga warqadda. All arrinta in turjumaad ah ee image ka RGB in CMYK model model.

Si aad u aragto sida sawirka eegi doonaa sida warqad, waxaad isticmaali kartaa barnaamijka Adobe Photoshop. Xaaladdan oo kale, image la saxar karaa si loo helo natiijada ugu wanaagsan.

Haatan waad garanaysaan waxa CMYK ah, gaabinta iyo waxa ka dhiman waxa ay leedahay istaagay. Inta badan, in mustaqbalka dhow in ay meel ku yimaado nidaamka badan oo horumarsan midab in kor u qaadi doontaa tayada image daabacaadda.
