Ofseta druka ir netie\u0161s plakan\u0101s drukas process, kas m\u016bsdien\u0101s tiek pla\u0161i izmantots, jo \u012bpa\u0161i profesion\u0101laj\u0101 poligr\u0101fij\u0101. Termins \u201eofsets\u201c attiecas uz to, ka druka netiek druk\u0101ta tie\u0161i no drukas materi\u0101la. Spiediena plate<\/a> tiek p\u0101rnests uz pap\u012bra, bet vispirms tiek \u201enob\u012bd\u012bts\u201c (p\u0101rnests) uz segas cilindra, pirms drukas mot\u012bvs tiek p\u0101rnests uz pap\u012bra vai drukas substr\u0101ta.<\/p>\n

Ofseta drukas process 20. gadsimt\u0101 att\u012bst\u012bj\u0101s no litogr\u0101fijas, un, ievie\u0161ot jaunus materi\u0101lus un iek\u0101rtas, tas ir nep\u0101rtraukti optimiz\u0113ts. Pieaugot digitaliz\u0101cijai, ofseta druka bie\u017ei tiek papildin\u0101ta ar digit\u0101lo druk\u0101\u0161anu, tom\u0113r t\u0101 joproj\u0101m ir v\u0113lamais drukas process, jo ir efekt\u012bvs lielu tir\u0101\u017eu gad\u012bjum\u0101.<\/p>\n

Ofseta drukas principa pamat\u0101 ir tauku, t. i., e\u013c\u013cainas kr\u0101sas un \u016bdens, \u0137\u012bmisk\u0101 atgr\u016b\u0161ana.

Tinte piestiprin\u0101s tikai pie apdrukas (hidrofobaj\u0101m) zon\u0101m, bet neapdruk\u0101jam\u0101s, hidrofil\u0101s zonas uzs\u016bc \u016bdeni un t\u0101d\u0113j\u0101di paliek bez tintes. Netie\u0161\u0101 p\u0101rnese caur elast\u012bgo gumijas segu nodro\u0161ina vienm\u0113r\u012bgu un prec\u012bzu apdruku.<\/p>\n
