Birka\u00e7 y\u0131ld\u0131r, bask\u0131 m\u00fcrekkeplerinin renk merkezli \u00f6l\u00e7\u00fcm\u00fc i\u00e7in olanaklar giderek daha basit ve ucuz hale gelmi\u015ftir. Bu nedenle genellikle bask\u0131 m\u00fcrekkeplerinin \u00f6l\u00e7\u00fcm\u00fcn\u00fcn basit, ucuz ve hepsinden \u00f6nemlisi son derece hassas oldu\u011funa inan\u0131l\u0131r. Ve bu, farkl\u0131 marka ve nesil \u00f6l\u00e7\u00fcm cihazlar\u0131 i\u00e7in de ge\u00e7erlidir. Peki bu do\u011fru mu?<\/strong><\/p>\n

Ancak ger\u00e7ekte durum farkl\u0131 g\u00f6r\u00fcnmektedir.

Peki sapmalar neden bu kadar b\u00fcy\u00fck?<\/p>\n

\u0130lk olarak, \u00f6l\u00e7\u00fcm cihazlar\u0131 \u00f6l\u00e7\u00fclecek y\u00fczeyleri ayd\u0131nlatma \u015fekilleri bak\u0131m\u0131ndan farkl\u0131l\u0131k g\u00f6sterir. Bu iki a\u00e7\u0131dan \u00f6nemlidir: bir yandan, malzemeye ba\u011fl\u0131 olarak, \u00f6l\u00e7\u00fcmler birbirinden b\u00fcy\u00fck \u00f6l\u00e7\u00fcde sapabilir, \u00e7\u00fcnk\u00fc \u00f6rne\u011fin, \u0131\u015f\u0131k sadece bir \u0131\u015f\u0131k kayna\u011f\u0131ndan \u00f6l\u00e7\u00fcm y\u00fczeyine parlar ve \u00f6l\u00e7\u00fcl\u00fcr. \u00d6rne\u011fin bir \u00f6l\u00e7\u00fcm cihaz\u0131nda \u00f6l\u00e7\u00fcm y\u00fczeyine 45 derecelik bir a\u00e7\u0131yla vuran ve yans\u0131mas\u0131 \u00f6l\u00e7\u00fclen tek bir lamba varsa, \u00f6l\u00e7\u00fcm cihaz\u0131n\u0131 sadece kendi ekseni etraf\u0131nda d\u00f6nd\u00fcrd\u00fc\u011f\u00fcn\u00fczde \u00f6l\u00e7\u00fcm Delta-E 3.0'a kadar sapabilir.

Bunun i\u00e7in \u00e7\u00f6z\u00fcm: Birka\u00e7 \u0131\u015f\u0131k kayna\u011f\u0131 bir \u00f6l\u00e7\u00fcm cihaz\u0131na da\u011f\u0131t\u0131l\u0131r veya ideal olarak, bu t\u00fcr etkileri en aza indirmek i\u00e7in ayd\u0131nlatma do\u011frudan 45 derecelik bir a\u00e7\u0131yla bir daire i\u00e7inde yay\u0131l\u0131r.<\/p>\n

I\u015f\u0131k kaynaklar\u0131<\/strong><\/p>\n

Ancak ayd\u0131nlatma t\u00fcr\u00fc de bir rol oynar. Ge\u00e7mi\u015fte, ayd\u0131nlatma i\u00e7in a\u011f\u0131rl\u0131kl\u0131 olarak tungsten lambalar kullan\u0131l\u0131yordu ve bu da iyi bir Spektrum<\/a> Bununla birlikte, spektrumlar\u0131 lamban\u0131n \u00f6mr\u00fc boyunca, \u00f6zellikle UV aral\u0131\u011f\u0131nda \u00f6nemli \u00f6l\u00e7\u00fcde de\u011fi\u015fir ve bu nedenle yanl\u0131\u015f \u00f6l\u00e7\u00fcmlere yol a\u00e7abilir. Ayr\u0131ca, bask\u0131 makinesinden yeni \u00e7\u0131km\u0131\u015f ve hala \u0131slak renklere sahip bir bask\u0131n\u0131n \u00f6nemli \u00f6l\u00e7\u00fcde daha y\u00fcksek Glamour<\/a>- ve yans\u0131ma fakt\u00f6r\u00fc, yani bir hafta sonra m\u00fc\u015fteriye teslim edildi\u011finde ayn\u0131 bask\u0131. Parlakl\u0131ktaki bu farkl\u0131l\u0131klar \u015fimdiye kadar polarizasyon filtreleri kullan\u0131larak m\u00fcmk\u00fcn oldu\u011funca ortadan kald\u0131r\u0131lm\u0131\u015ft\u0131r.<\/p>\n

Yeni sistemden bu yana D50<\/a> ISO 13655:2009 \u0131\u015f\u0131k standard\u0131 D50 neon t\u00fcplerle ayd\u0131nlatmay\u0131 gerektirir, ancak bunlar kullan\u0131\u015fl\u0131 \u00f6l\u00e7\u00fcm cihazlar\u0131na pek uymaz. Bu nedenle, \u00e7e\u015fitli ayd\u0131nlatma ko\u015fullar\u0131 defi<\/a>kategorize edilmi\u015ftir: M0, M1, M2 ve M3.<\/p>\n

M0, I1 Pro veya UV filtresiz ve polarize filtresiz DTP 41 veya DTP 70'de oldu\u011fu gibi geleneksel tungsten ayd\u0131nlatmad\u0131r<\/p>\n

M2 beschreibt das selbe, aber mit UV-Cut Filter, wie er z.B. im I1 Pro UV-Cut zum Einsatz kommt. Vorteile des UV-Filters: harmonische Ergebnisse auch bei Papieren mit optischem Parlat\u0131c\u0131<\/a>. Nachteil: Typische Produktionspapiere enthalten heute teilweise viele optik parlat\u0131c\u0131lar<\/a>UV \u0131\u015f\u0131\u011f\u0131n\u0131 emerek ve mavi \u0131\u015f\u0131k olarak yans\u0131tarak ka\u011f\u0131d\u0131n daha beyaz g\u00f6r\u00fcnmesini sa\u011flar. Bu nedenle ka\u011f\u0131tlar UV kesim alt\u0131nda tamamen ayn\u0131 g\u00f6r\u00fcnebilir, ancak g\u00fcn \u0131\u015f\u0131\u011f\u0131nda veya D50 alt\u0131nda son derece farkl\u0131 olabilir. Ve pratikte, bas\u0131l\u0131 \u00fcr\u00fcnler neredeyse hi\u00e7bir zaman UV kesim ko\u015fullar\u0131 alt\u0131nda g\u00f6r\u00fcnt\u00fclenmez.<\/p>\n

M3 \u00f6l\u00e7\u00fcm cihazlar\u0131 hem UV filtresine hem de polarizasyon filtresine sahiptir.<\/p>\n

M1: M1 modu, a\u015fa\u011f\u0131daki \u00f6zelliklere g\u00f6re bir D50 \u0131\u015f\u0131k kayna\u011f\u0131 kullan\u0131larak elde edilir ISO 3664:2009<\/a> kullan\u0131lmaktad\u0131r.
