Parizvino, mune tekinoroji yekutonga kwemavara, iyo inonzi color feature yekubatanidza nzvimbo inoshandisa chromaticity nzvimbo yeCIE1976Lab. Mavara pane chero mudziyo anogona kuchinjirwa kune ino nzvimbo kuti iite "yepasi rose" tsananguro nzira, uye ipapo kuenderana kwemavara uye kutendeuka kunoitwa. Mukati mekombuta inoshanda sisitimu, basa rekushandisa kuchinjika kwemavara rinopedzwa ne "color matching module", iro rine kukosha kukuru kwekuvimbika kwekushandurwa kwemavara uye kuenderana kwemavara. Saka, nzira yekuwana sei kuchinjisa kwemavara mune "yepasirese" nzvimbo yemavara, kuwana kurasikirwa kana kushoma kurasikirwa kwemavara?
Izvi zvinoda seti yega yega yemidziyo kugadzira chimiro, inova iyo mudziyo wemavara emhando faira.
Isu tinoziva kuti zvishandiso zvakasiyana-siyana, zvishandiso, uye maitiro anoratidza akasiyana maitiro kana achiratidzira uye nekufambisa mavara. Mukutonga kwemavara, kuratidza mavara anoratidzwa pane chimwe chishandiso nekuvimbika kwakanyanya pane chimwe chishandiso, isu tinofanirwa kunzwisisa maitiro ekuratidzwa kwemavara emavara pamidziyo yakasiyana.
Sezvo mudziyo wakazvimirira nzvimbo yeruvara, CIE1976Lab chromaticity space, yasarudzwa, iwo mavara echishandiso anomiririrwa nekunyorerana pakati pekutsanangurwa kwechigadzirwa kukosha uye kukosha kwechromaticity ye "universal" color space, inova gwaro rekutsanangura ruvara rwemudziyo. .
1. Device color color tsananguro faira
Mune tekinoroji yekutonga kwemavara, anonyanya kuzivikanwa marudzi echishandiso ruvara rwemhando yekutsanangura mafaera ndeaya:
Mhando yekutanga ndeye scanner feature file, iyo inopa manyoro akajairwa kubva kumakambani eKodak, Agfa, uye Fuji, pamwe chete nedata rakajairwa rezvinyorwa izvi. Aya manyoro anoiswa pachishandiswa scanner, uye mutsauko uripo pakati pe data yakaongororwa uye yakajairwa manuscript data inoratidza maitiro e scanner;
Rudzi rwechipiri ndiro faira rekuratidzira, iyo inopa imwe software inokwanisa kuyera kupisa kwemavara kwechiratidziro, uye yobva yagadzira chivharo chemavara pachiratidziro, chinoratidza maitiro echiratidziro; Rudzi rwechitatu ndiyo faira yefaira yechishandiso chekudhinda, iyo inopawo seti yesoftware. Iyo software inogadzira girafu ine mazana emabhuraki emavara mukombuta, yobva yaburitsa girafu pane chinobuda mudziyo. Kana iri printa, inoisa sampuli zvakananga, uye muchina wekudhinda unotanga kuburitsa firimu, samples, uye maprints. Kuyerwa kwemifananidzo iyi inobuda kunoratidza ruzivo rwefaira remuchina wekudhinda.
Iyo profil yakagadzirwa, inozivikanwawo seyeruvara chimiro faira, ine matatu makuru mafomati: faira musoro, tag tafura, uye tag element data.
·Musoro wefaira: Iine ruzivo rwekutanga nezve faira remhando yefaira, senge saizi yefaira, mhando yenzira yekutonga kwemavara, vhezheni yefaira fomati, rudzi rwechishandiso, nzvimbo yeruvara rwechishandiso, nzvimbo yemavara yefaira rechimiro, sisitimu yekushandisa, mugadziri wemudziyo. , chinangwa chekudzorera ruvara, midhiya yepakutanga, chiedza chinyorwa chemavara data, nezvimwewo. Musoro wefaira unotora huwandu hwe128 bytes.
· Tag Tafura: Iine ruzivo nezve huwandu hwezita, nzvimbo yekuchengetera, uye saizi yedata yema tag, asi haisanganisi iyo chaiyo yemukati ma tag. Iro zita rehuwandu hwemategi rinotora 4 bytes, nepo chinhu chimwe nechimwe chiri patafura yemateki chinotora 12 bytes.
·Markup element data: Inochengetedza ruzivo rwakasiyana-siyana runodiwa kune manejimendi emavara munzvimbo dzakatarwa zvinoenderana nemirairo iri patafura yekumaka, uye inosiyana zvichienderana nekuoma kweruzivo rwemakapu uye saizi yedata rakanyorwa.
Kune iwo mavara emhando mafaira emidziyo mumabhizinesi ekudhinda, vashandisi vemifananidzo uye mameseji ekugadzirisa ruzivo vane nzira mbiri dzekuvawana:
·Nzira yekutanga: Paunenge uchitenga zvishandiso, mugadziri anopa chimiro pamwe chete nemidziyo, iyo inogona kusangana neyakajairwa color management zvinodiwa zvemidziyo. Kana uchiisa software yekushandisa yemidziyo, iyo mbiri inoiswa muhurongwa.
·Yechipiri nzira ndeyekushandisa yakasarudzika profil software kugadzira akakodzera mavara erondedzero mafaera zvichienderana nemamiriro chaiwo emidziyo iripo. Iri faira rinogadzirwa rinowanzo nyatsoita uye rinoenderana nemamiriro chaiwo emushandisi. Nekuda kwekuchinja kana kutsauka mumamiriro emidziyo, zvishandiso, uye maitiro nekufamba kwenguva. Naizvozvo, zvinodikanwa kuti ugadzirise iyo mbiri nguva nenguva kuti ienderane nemamiriro ekupindura kwemavara panguva iyoyo.
2. Kutapurirana kwemavara mumudziyo
Zvino, ngatitarisei kuti mavara anofambiswa sei pamidziyo yakasiyana-siyana.
Chekutanga, kune chinyorwa chine mavara akajairwa, scanner inoshandiswa kuita scan uye kuipinza. Nekuda kwechimiro che scanner, inopa hukama hunoenderana kubva kune ruvara (kureva dzvuku, girini, uye yebhuruu tristimulus kukosha) pa scanner kune iyo CIE1976Lab chromaticity space. Naizvozvo, iyo inoshanda sisitimu inogona kuwana iyo chromaticity kukosha Lab yemuvara wepakutanga zvinoenderana nehukama hwekutendeuka uku.
Mufananidzo wakaongororwa unoratidzwa pachiratidziro. Sezvo sisitimu yacho yagona kuwirirana pakati peLab chromaticity values uye tsvuku, girinhi, uye yebhuruu masaini ekutyaira pachiratidziro, hazvifanirwe kushandisa zvakananga tsvuku, yegirinhi, uye yebhuruu chromaticity kukosha kweiyo scanner panguva yekuratidzira. Panzvimbo iyoyo, kubva kuLab chromaticity kukosha kweiyo yapfuura manyoro, zvinoenderana nehukama hwekushandura hwakapihwa neiyo ratidziro mbiri, chiratidzo chekutyaira chetsvuku, girinhi, uye bhuruu chinogona kunyatso kuratidza ruvara rwepakutanga pachiratidziri chinowanikwa, Dhiraivha chiratidziro. kuratidza mavara. Izvi zvinoita kuti ruvara runoratidzwa pamonitor ruenderane neruvara rwepakutanga.
Mushure mekuona iyo chaiyo yemavara yemifananidzo, mushandisi anogona kugadzirisa mufananidzo zvichienderana neruvara rwescreen zvinoenderana nezvinodiwa nevatengi. Pamusoro pezvo, nekuda kweiyo mbiri ine michina yekudhinda, iyo chaiyo ruvara mushure mekudhinda inogona kucherechedzwa pachiratidziro mushure mekuparadzaniswa kwemavara emufananidzo. Mushure mokunge mushandisi agutsikana nemuvara wemufananidzo, mufananidzo wacho wakaparadzaniswa uye wakachengetwa. Munguva yekupatsanurwa kwemavara, chikamu chaicho chemadots chinowanikwa zvichienderana nehukama hwekushandurwa kweruvara hunotakurwa neprofile yemuchina wekudhinda. Mushure mekuita RIP (Raster Image Processor), kurekodha uye kudhinda, kudhinda, proofing, uye kudhinda, kopi yakadhindwa yegwaro rekutanga inogona kuwanikwa, nokudaro kupedza hurongwa hwese.
