Underf\u00e4rgsborttagning eller underf\u00e4rgsreduktion anv\u00e4nds vid separering av LAB<\/a> eller RGB<\/a> till CMYK<\/a>. Syftet med underf\u00e4rgsreducering \u00e4r att minska CMY-komponenterna i svarta pixlar f\u00f6r att minska den totalaf\u00e4rgapplikationen<\/a>.<\/p>\n

F\u00e4rger som best\u00e5r av endast en eller tv\u00e5 prim\u00e4rf\u00e4rger, t.ex. ren cyan eller ren r\u00f6d fr\u00e5n magenta och gul, p\u00e5verkas inte av UCR. Led<\/a>, UCR-processen anv\u00e4nds endast f\u00f6r f\u00e4rger som best\u00e5r av alla tre kromatiska f\u00e4rger.<\/p>\n

Processen \u00e4r permanent implementerad f\u00f6r separationer som anv\u00e4nder en CMYK ICC<\/a>-profil och kan inte \u00e4ndras. Begr\u00e4nsningen av den maximala bl\u00e4ckapplikationen till 330 eller 300% \u00e4r ett resultat av UCR, eftersom h\u00f6gre bl\u00e4ckapplikationer kraftigt skulle f\u00f6rl\u00e4nga torktiderna och mycket tjocka bl\u00e4cklager kan spricka n\u00e4r man till exempel viker papper.<\/p>\n
