Standarden kom som en overraskelse og blev d\u00e5rligt kommunikeret inden for branchen. Alle proofing-substrater, der er tilg\u00e6ngelige for udbydere af proofing-tjenester, indeholder ingen eller n\u00e6sten ingen optiske blegemidler - dette var tidligere et krav. Og under den gamle D50-standardbelysning - som ikke indeholdt nogen UV-komponenter - s\u00e5 pr\u00f8vetryk og produktionsk\u00f8rsel identisk ud, fordi de optiske lysere ikke blev behandlet i produktionsk\u00f8rslen. Med alle nye trykmaskiner, der allerede er udstyret med lysr\u00f8r af den nye standard, kan pr\u00f8ve- og produktionsk\u00f8rsel ikke l\u00e6ngere sammenlignes: Det ser helt anderledes ud, alene forskellene i papirets hvidhed skriger til himmels.<\/p>\n<p>Trykkerier og udbydere af korrekturpr\u00f8vningstjenester er faktisk tvunget til at udskifte de gamle r\u00f8r med nye. Dette er imidlertid ofte et kompliceret sp\u00f8rgsm\u00e5l: De gamle diffusionssk\u00e6rme, som er monteret foran neonr\u00f8rene, har hidtil for det meste f\u00e5et installeret et ekstra UV-filter for at sikre, at der ikke kommer mere UV-indhold igennem. S\u00e5 n\u00e5r nye ISO 2664:2009-r\u00f8r med UV-filter monteres bag diffusionssk\u00e6rmene, er det netop denne UV-komponent, der desv\u00e6rre mangler igen foran diffusionssk\u00e6rmene ... Trykkerierne st\u00e5r derfor over for nogle ekstra omkostninger.<\/p>\n<p>Vi er sp\u00e6ndte p\u00e5 at se, hvorn\u00e5r de f\u00f8rste proofpapirer med lysere kommer p\u00e5 markedet, s\u00e5 man igen kan sammenligne proof og trykoplag rent i trykkeriet.
