Abaningi emhlabeni wokukhanyisa bayazi nge-CRI, eyaziwa nangokuthi Index Rendering Index. Kungachazwa kangcono njengesilinganiso sobuningi bekhono lomthombo wokukhanya onikeziwe ukuze liveze imibala yezinto ezihlukahlukene ngokwethembeka uma kuqhathaniswa nomthombo wokukhanya okahle noma wemvelo. Ukuphakama kwevelu ye-CRI yomthombo wokukhanya, kulapho okunembe kakhudlwana ukubukeka kombala wento ethile.
Ikhono le-CIE Ra lokubikezela ukubukeka kombala liye lagxekwa ngokuvuna izilinganiso ezisekelwe kumamodeli wokubukeka kombala, njenge-CIECAM02 kanye ne-CIE metamerism index yezilingisi zasemini. I-CRI ayiyona inkomba enhle yokusetshenziswa ekuhloleni okubonakalayo kwemithombo yokukhanya, ikakhulukazi imithombo engaphansi kuka-5000 kelvin (K). Izindinganiso ezintsha, njenge-IES TM-30, zixazulula lezi zinkinga futhi seziqalile ukufaka esikhundleni sokusetshenziswa kwe-CRI phakathi kwabaklami bokukhanyisa abaqeqeshiwe. Kodwa-ke, i-CRI isajwayelekile phakathi kwemikhiqizo yokukhanyisa yasendlini.
I-TM30-15 Iqukethe Izingxenye Ezi-3 Eziyinhloko
- I-Rf: Ifana ne-CIE Ra (CRI). Ifaka uphawu ukushintsha kombala okumaphakathi kwe-99 CES ukuze kubonise izinga eliphelele lokufana phakathi komthombo wokuhlola nesikhanyiso esiyisithenjwa. Amanani asukela ku-0 kuye ku-100.
- I-Rg: Iqhathanisa indawo evalwe yi-avareji yezixhumanisi ze-chromaticity kumgqomo ngamunye we-hue engu-16 ukuze ibonise izinga lesilinganiso sokugcwala komthombo wokuhlola uma kuqhathaniswa nesikhanyiso esiyireferensi. Isikolo esiphakathi nendawo singu-100, amanani amakhulu kuno-100 abonisa ukwanda kokugcwala kwesikhala kanye namanani angaphansi kuka-100 abonisa ukwehla kokugcwala kwesikhala. Ububanzi bamanani bukhula njengoba ukwethembeka kuncipha.
- Isethulo esiyisithombe se-Rg esizomela ngokubonakalayo ukuthi yimiphi imibala ehlanjululwayo noma ecace kakhulu ngenxa yomthombo wokukhanya. Iqukethe I-Color Vector Graphic, I-Color Saturation Graphic.
I-Color Vector Graphic: Ihlinzeka ngokuboniswa okubonakalayo kwezinguquko ze-hue kanye nokugcwala kwesikhala ngokusekelwe ekunikezeni okumaphakathi emgqonyeni ngamunye we-hue, uma kuqhathaniswa nereferensi. Umfanekiso unikeza ukuqonda okusheshayo kokuthi ama-hues ahlukene anikezwa kanjani ngezindlela ezahlukene.
Umfanekiso Wokugcwaliswa Kombala: Ihlinzeka ngokumelela okubonakalayo okulula kwezinguquko zokugcwaliswa kwesikhala kuphela ngokusekelwe ekusebenzeni okumaphakathi kumgqomo ngamunye we-hue.

Kungani i-TM30-15 ibalulekile?
- I-CRI ingatholakala kumalambu yonke indawo namuhla futhi ayihambi njengamanje. I-IES isalinde impendulo futhi cishe izozivumelanisa ne-TM30-15 ngaphambi kokuthatha indawo ye-CRI.
- I-TM30-15 cishe izosetshenziswa ngezikhathi ezithile, ikakhulukazi ezinhlelweni zokusebenza lapho ukunikezwa kombala kuyinto ekhathaza kakhulu (izici, izitolo, njll.).
- Okuhlobene ne-TM30-15, i-CRI ingakhohliswa, njengoba iqhathanisa kuphela 9 nemibala engu-99 TM30-15 ehambisanayo. Ngakho-ke uma unjiniyela okukhiphayo komkhiqizo wakho kuleyo mibala engu-9, ungakhulisa isikolo sakho ngaphandle kokuthuthukisa ikhwalithi yomthombo wokukhanya.
Izicacisi
- I-TM-30-15 iyindlela egunyaziwe. Yisebenzise futhi unikeze impendulo ukuze uyisize ifinyelele ekuvuthweni.
- Ukukhetha umthombo wokukhanya “ongcono” kungase kube inselele kodwa futhi kuvuze kakhulu.
Ngezansi kukhona okubonakalayo okunemininingwane yezinguquko njengoba ushintsha amamethrikhi ahlukahlukene abalwe ngenhla, njenge-Rf, Rg, ne-CRI, kanye nokuqhathaniswa kwamagrafu e-vector yombala.
