UV tisk ozna\u010duje tiskov\u00e9 procesy v digit\u00e1ln\u00edm tisku, v offsetov\u00e9m tisku<\/a> a v flexografick\u00e9m tisku<\/a>, p\u0159i nich\u017e jsou tiskov\u00e9 barvy vytvrzov\u00e1ny pomoc\u00ed v\u00fdkonn\u00fdch UV lamp p\u0159\u00edmo po nanesen\u00ed. D\u00edky tomu jsou v\u00fdtisky stabiln\u00ed, odoln\u00e9 proti po\u0161kr\u00e1b\u00e1n\u00ed a nepronikaj\u00ed do pap\u00edru nebo tiskov\u00e9ho substr\u00e1tu. To znamen\u00e1, \u017ee v\u00fdtisky lze okam\u017eit\u011b zpracov\u00e1vat.<\/p>\n

Zat\u00edmco d\u0159\u00edve se ke generov\u00e1n\u00ed siln\u00e9ho UV z\u00e1\u0159en\u00ed pou\u017e\u00edvaly rtu\u0165ov\u00e9 v\u00fdbojky, dnes se p\u0159ev\u00e1\u017en\u011b pou\u017e\u00edvaj\u00ed LED UV syst\u00e9my, a proto se tyto procesy \u010dasto ozna\u010duj\u00ed jako LED UV tisk<\/a>.<\/p>\n

Nejv\u011bt\u0161\u00ed v\u00fdhodou je nejen rychl\u00e9 zpracov\u00e1n\u00ed, ale zejm\u00e9na skute\u010dnost, \u017ee su\u0161en\u00ed prob\u00edh\u00e1 ve zlomc\u00edch sekundy. To znamen\u00e1, \u017ee lze tisknout i na podklady, kter\u00e9 nejsou sav\u00e9 (nap\u0159. samolepky nebo plechovky), a na sav\u00fd p\u0159\u00edrodn\u00ed pap\u00edr<\/a> lze dos\u00e1hnout vy\u0161\u0161\u00ed \u00farovn\u011b barevnosti, proto\u017ee barva se nevst\u0159eb\u00e1v\u00e1 do pap\u00edru, ale vytvrzuje se p\u0159\u00edmo na povrchu pap\u00edru.<\/p>\n

Toho se dosahuje vytvrzov\u00e1n\u00edm fotoinici\u00e1tor\u016f, tj. l\u00e1tek citliv\u00fdch na sv\u011btlo, v tiskov\u00fdch barv\u00e1ch polymerac\u00ed.<\/p>\n
