Wszyscy rozumiemy, \u017ce istniej\u0105 r\u00f3\u017cne korzy\u015bci wynikaj\u0105ce z u\u017cywania PDF<\/a> ale s\u0142ysza\u0142e\u015b o alternatywnym formacie \u201ePDF\/A\u201d? Je\u015bli nie, zajrzyjmy do tego teraz!!<\/strong><\/p>\n

Co to jest PDF\/A?<\/h2>\n

U\u017cyciePDF\/A<\/a>U\u017cycie PDF\/A ma na celu specjalnie przechowywanie i zachowanie dokument\u00f3w elektronicznych na d\u0142ugie lata. Jest to wersja formatu Portable Document Format zgodna z normami ISO (PDF). W przeciwie\u0144stwie do PDF, kt\u00f3ry pozwala na funkcje takie jak szyfrowanie i \u0142\u0105czenie czcionek, PDF\/A je ogranicza, poniewa\u017c nie s\u0105 one idealne do d\u0142ugoterminowego archiwizowania<\/a>. Oznacza to, \u017ce dokument mo\u017cna odtworzy\u0107 w taki sam spos\u00f3b za pomoc\u0105 formatu PDF\/A, niezale\u017cnie od u\u017cywanej aplikacji. W zasadzie plik zawiera wszystkie informacje potrzebne do ci\u0105g\u0142ego wy\u015bwietlania dokumentu i wszystkich jego cz\u0119\u015bci, chroni\u0105c Twoje dokumenty przed zagubieniem, zapewniaj\u0105c ich dost\u0119pno\u015b\u0107 i bezpiecze\u0144stwo na d\u0142ugie lata.<\/p>\n

Jakie s\u0105 r\u00f3\u017cne typy PDF\/A?<\/h2>\n

\u0141\u0105cz\u0105c r\u00f3\u017cne standardy PDF\/A i poziomy zgodno\u015bci, mo\u017cna osi\u0105gn\u0105\u0107 r\u00f3\u017cnorodne warianty PDF\/A. Ka\u017cdy standard PDF\/A okre\u015bla r\u00f3\u017cnorodno\u015b\u0107 funkcji i metod kompresji obraz\u00f3w, kt\u00f3re mog\u0105 by\u0107 u\u017cywane do zachowania tre\u015bci pliku.<\/p>\n

PDF\/A-1<\/strong>
\nPierwszy standard PDF\/A, kt\u00f3ry wci\u0105\u017c jest u\u017cywany dzisiaj i jednocze\u015bnie najbardziej ograniczaj\u0105cy, to PDF\/A-1. Poniewa\u017c PDF\/A-1 opiera si\u0119 na przestarza\u0142ym standardzie PDF 1.4, kt\u00f3ry zosta\u0142 wydany przez Adobe Systems w 2001 roku, nie jest zgodny z warstwami, za\u0142\u0105cznikami ani JPEG 2000.<\/p>\n

PDF\/A-2<\/strong>
\nPrzezroczysto\u015b\u0107 to jedna z wielu nowych cech dodanych do PDF\/A-2, kt\u00f3re nie wyst\u0119powa\u0142y w PDF 1.4. Do dodatk\u00f3w nale\u017cy: warstwy, lepsza kompresja obraz\u00f3w (JPEG 2000 i JBIG 2) oraz za\u0142\u0105czniki \u2014 pod warunkiem, \u017ce za\u0142\u0105czniki s\u0105 w formacie PDF\/A.<\/p>\n

PDF\/A-3<\/strong>
\nPDF\/A-3 i PDF\/A-2 s\u0105 niemal wzajemnie zamienne. Jedyn\u0105 r\u00f3\u017cnic\u0105 jest to, \u017ce PDF\/A-3 pozwala na za\u0142\u0105czanie dowolnego rodzaju plik\u00f3w. Jednak poza gwarantowaniem poprawnego wyodr\u0119bnienia, do dodatkowych dzia\u0142a\u0144 na za\u0142\u0105czonych plikach nie jest konieczny przegl\u0105darka PDF\/A.<\/p>\n

PDF\/A-4<\/strong>
\nNast\u0119pnym standardem PDF\/A, znanym jako PDF\/A-4, b\u0119dzie wydanie jako ISO 19005-4:2020 w listopadzie 2020 roku. A-4 aktualizuje PDF\/A, aby by\u0142 zgodny z PDF 2.0, najnowszym standardem ISO PDF. Znacz\u0105co, PDF\/A-4 nie wykorzystuje rozr\u00f3\u017cnionych poziom\u00f3w zgodno\u015bci a, b i u.<\/p>\n

Jak przekszta\u0142ci\u0107 PDF na PDF\/A?<\/h2>\n

Na rynku dost\u0119pnych jest wiele konwerter\u00f3w PDF do PDF\/A, ale warto u\u017cywa\u0107 tylko \u201ejakiegokolwiek\u201d konwertera, poniewa\u017c to r\u00f3wnie\u017c kwestia bezpiecze\u0144stwa cybernetycznego.
