Dokaz<\/a> (nebo zku\u0161ebn\u00ed v\u00fdtisky) v polygrafick\u00e9m odv\u011btv\u00ed ozna\u010duje barevn\u011b p\u0159esnou a pr\u00e1vn\u011b z\u00e1vaznou simulaci v\u00fdsledku tisku pro \u00fa\u010dely kontroly. Norma odpov\u011bdn\u00e1 za n\u00e1tisky je ISO 12647<\/a>-7:2016, tj. aktu\u00e1ln\u00ed revize z roku 2016.<\/p>\n

Proofy slou\u017e\u00ed k simulaci toho, jak bude vypadat pozd\u011bj\u0161\u00ed v\u00fdsledek tisku, aby bylo mo\u017en\u00e9 odhalit p\u0159\u00edpadn\u00e9 chyby ji\u017e v ran\u00e9 f\u00e1zi. T\u00edm se zabr\u00e1n\u00ed tomu, aby se chyby objevily a\u017e po tisku, proto\u017ee pak je oprava n\u00e1kladn\u011bj\u0161\u00ed.<\/p>\n

Korektury (spr\u00e1vn\u011b: kontraktn\u00ed korektury<\/a> nebo kontraktn\u00ed korektury<\/a>) jsou certifikovan\u00fdm zku\u0161ebn\u00edm m\u00e9diem ISO pro grafick\u00fd pr\u016fmysl. Proofy simuluj\u00ed barevnost ofsetov\u00e9ho tisku<\/a> nebo hlubotisk<\/a> barevn\u011b a pr\u00e1vn\u011b z\u00e1vazn\u011b v \u00fazk\u00fdch toleranc\u00edch normy ISO 12647-7. Dnes se t\u00e9m\u011b\u0159 v\u00fdhradn\u011b po\u010d\u00edtaj\u00ed pomoc\u00ed RIP<\/a> a n\u00e1sledn\u011b se vyr\u00e1b\u011bj\u00ed pomoc\u00ed inkoustov\u00fdch tisk\u00e1ren na certifikovan\u00fdch pap\u00edrech pro n\u00e1tisky.<\/p>\n

Data pro n\u00e1tisky se p\u0159evedou na separace a pot\u00e9 se znovu sestav\u00ed do slo\u017een\u00e9ho obrazu, aby se spr\u00e1vn\u011b simuloval p\u0159etisk a trapping. Data se pot\u00e9 p\u0159enesou jako nov\u011b vytvo\u0159en\u00fd kompozit do inkoustov\u00e9 tisk\u00e1rny, obvykle s v\u00edce ne\u017e 8 barvami, kter\u00e1 data vytiskne. Krom\u011b tiskov\u00fdch dat mus\u00ed m\u00edt n\u00e1tisky tak\u00e9 UGRA<\/a>\/Fogra<\/a> medi\u00e1ln\u00ed kl\u00edn<\/a>, aby byly barevn\u011b p\u0159esn\u00e9 a pr\u00e1vn\u011b z\u00e1vazn\u00e9. D\u00edky standardizovan\u00e9mu kl\u00ednu m\u016f\u017ee tisk\u00e1rna kontrolovat spr\u00e1vnost n\u00e1hled\u016f. Proto\u017ee mnoho tisk\u00e1ren nem\u00e1 tuto m\u011b\u0159ic\u00ed technologii k dispozici, jsou n\u00e1tisky \u010dasto opat\u0159eny p\u0159\u00edmo zku\u0161ebn\u00edm protokolem, kter\u00fd odr\u00e1\u017e\u00ed spr\u00e1vnost nam\u011b\u0159en\u00fdch hodnot medi\u00e1ln\u00edho kl\u00ednu p\u0159\u00edmo na n\u00e1tisc\u00edch.<\/p>\n

D\u0159\u00edv\u011bj\u0161\u00ed postupy, jako je chromalin apod., se dnes ji\u017e na trhu nevyskytuj\u00ed.<\/p>\n

Krom\u011b term\u00ednu \"d\u016fkazy\" se b\u011b\u017en\u011b pou\u017e\u00edvaj\u00ed tak\u00e9 term\u00edny jako barevn\u00e9 d\u016fkazy<\/a> nebo digit\u00e1ln\u00ed d\u016fkazy<\/a>.<\/p>\n

Krom\u011b nejvy\u0161\u0161\u00edho standardu smluvn\u00edch d\u016fkaz\u016f, zkr\u00e1cen\u011b \"d\u016fkaz\u016f\" (ISO 12647-7), definuje ISO 12647 tak\u00e9 term\u00edn \"validation print<\/a>s\" (ISO 12647-8) defi<\/a>niert. Valida\u010dn\u00ed tisk se vyzna\u010duje t\u00edm, \u017ee je m\u00e9n\u011b p\u0159esn\u00fd z hlediska barevnosti, ale lze jej vytv\u00e1\u0159et i na laserov\u00fdch tisk\u00e1rn\u00e1ch. Ve srovn\u00e1n\u00ed se smluvn\u00edmi n\u00e1tisky v\u0161ak p\u0159ipou\u0161t\u00ed podstatn\u011b v\u011bt\u0161\u00ed barevn\u00e9 odchylky a je pr\u00e1vn\u011b z\u00e1vazn\u00fd pouze po p\u0159edchoz\u00ed konzultaci. Skute\u010dn\u00e9 \"proofy\", tj. skute\u010dn\u00e9 smluvn\u00ed proofy podle normy ISO 12647-7, jsou v sou\u010dasn\u00e9 dob\u011b nejen zdaleka nejlep\u0161\u00ed variantou z hlediska barevnosti, ale tak\u00e9 jedin\u00fdmi pr\u00e1vn\u011b z\u00e1vazn\u00fdmi proofy.<\/p>\n
