SCTV ehk Spot Colour Tone Value (kohatooniv\u00e4\u00e4rtus) on v\u00e4rvitooni, alusv\u00e4rvi ja t\u00e4istooni vahelise kolorimeetrilise erinevuse suhe.<\/p>\n

SCTV p\u00f5hineb L*a*b*, parimal juhul ka spektriandmetel, ja t\u00f6\u00f6tab seet\u00f5ttu v\u00f5rdselt h\u00e4sti k\u00f5igi spetsiaalv\u00e4rvide<\/a>, tr\u00fckiprotsesside ja paberitega ning annab \u00fchtlase tulemuse. Kohav\u00e4rvide kalibreerimisel annab SCTV usaldusv\u00e4\u00e4rselt tulemuse, mille puhul 50 % v\u00e4rvitoon on visuaalselt v\u00e4ga l\u00e4hedane oodatavale 50 % v\u00e4limusele.<\/p>\n

Varasemalt on toonv\u00e4\u00e4rtuse suurendamine<\/a> (TVI<\/a>) defi<\/a>toonv\u00e4\u00e4rtuse sihtv\u00e4\u00e4rtused s\u00f5ltuvalt tr\u00fckiprotsessist ja substraadist. N\u00e4iteks ISO 12647<\/a>-2:2015 m\u00e4\u00e4rab 16 % punktitugevust ISO 12647<\/a>-2:2015.TP28T\/es\/lexico-2\/cmyk\/\" target=\"_self\" class=\"encyclopedia tooltipstered\">CMYK<\/a> pilditr\u00fckkimisel ja 22 % punktitugevust looduspaberile<\/a>.<\/p>\n

SCTV puhul on aga SCTV sihtv\u00e4\u00e4rtus sama, mis v\u00e4rvitooni v\u00e4\u00e4rtus. Tooniv\u00e4\u00e4rtus 50% peaks olema m\u00f5\u00f5detud v\u00e4\u00e4rtus 50%, k\u00f5ik teised tooniv\u00e4\u00e4rtused peaksid samuti olema vastavad pedant. See t\u00e4hendab, et SCTV on visuaalselt j\u00e4rjepidev, mis ei kehti tihedusp\u00f5histe l\u00e4henemisviiside puhul, ja seet\u00f5ttu sobib see paremini punktv\u00e4rvide jaoks.<\/p>","protected":false},"excerpt":{"rendered":"
