Standard PDF\/X4, nov\u00e1 specifikace pro export PDF, je k dispozici ji\u017e n\u011bkolik let. Jak\u00e9 jsou v\u0161ak skute\u010dn\u00e9 v\u00fdhody PDF\/X4?<\/p>\n

U\u017eivatel\u00e9 z oblasti tisku znaj\u00ed normy ISO PDF-X ji\u017e \u0159adu let. Zat\u00edmco n\u00e1zev PDF znamen\u00e1 \"Portable Document Format\", tj. p\u0159enosn\u00fd, a tedy p\u0159enositeln\u00fd dokument, PDF \"X\" je verze specializovan\u00e1 pro \"eXchange\", tj. v\u00fdm\u011bnu soubor\u016f PDF. Konkr\u00e9tn\u011b to znamen\u00e1, \u017ee mnoho funkc\u00ed, kter\u00e9 m\u016f\u017ee soubor PDF potenci\u00e1ln\u011b zobrazovat (formul\u00e1\u0159ov\u00e1 pole, v\u00fdpo\u010dty, 3D prvky, filmy atd.), ale kter\u00e9 nelze ovl\u00e1dat v tisku, je v PDF\/X zak\u00e1z\u00e1no, aby byla zaji\u0161t\u011bna bezpe\u010dn\u00e1 v\u00fdm\u011bna dat.<\/p>\n

Zat\u00edmco PDF\/X2 se t\u00e9m\u011b\u0159 nepou\u017e\u00edv\u00e1, PDF\/X1a a \/X3 jsou st\u00e1le standardy pro tiska\u0159sk\u00fd pr\u016fmysl; t\u00e9m\u011b\u0159 v\u0161echny online tisk\u00e1rny, jako je Flyeralarm atd., vy\u017eaduj\u00ed soubory PDF ve standardu PDF\/X-3. Pro\u010d? Soubory PDF\/X-1 nebo PDF\/X-3 p\u0159in\u00e1\u0161ej\u00ed tisk\u00e1rn\u00e1m mnoho v\u00fdhod: M\u00edsto otev\u0159en\u00fdch dat z Quark XPressu nebo Adobe InDesignu p\u0159in\u00e1\u0161\u00ed PDF tisk\u00e1rn\u00e1m mnohem men\u0161\u00ed n\u00e1roky. Nen\u00ed pot\u0159eba \u017e\u00e1dn\u00fd nativn\u00ed software, \u017e\u00e1dn\u00e1 p\u00edsma, \u017e\u00e1dn\u00e9 odkazy na obr\u00e1zky ... to v\u0161e d\u0159\u00edve st\u00e1lo \u010das a pen\u00edze. A aby se PDF zavr\u0161ilo, p\u0159ibylo X, kter\u00e9 znamenalo zabezpe\u010den\u00ed v\u00fdroby, proto\u017ee v PDF se sm\u011bly pou\u017e\u00edvat jen ty v\u011bci, kter\u00e9 bylo mo\u017en\u00e9 tak\u00e9 bezpe\u010dn\u011b vystavit a vytisknout.<\/p>\n

Jednou z nejv\u011bt\u0161\u00edch nev\u00fdhod PDF\/X-1 a \/X-3 byla dosud nep\u0159ehlednost:<\/p>\n
