Dijital Baskı Sisteminde Farklı Tramlama Yöntemlerinin Baskı Kalitesine Etkisinin İncelenmesi

Dijital baskı, ileri baskı teknolojileri ile bilgisayar ortamında hazırlanan tasarım ve fotoğrafların farklı malzemeler üzerine kaliteli ve hızlı bir şekilde basılması işlemidir. Günümüzde etkinliğini artıran dijital baskı sistemi, kurulduğu ilk yıllardan itibaren teknoloji ile büyük adımlar atmış ve son on yıldır sektörde söz sahibi olmaya başlamıştır. Tasarımı ürün haline getirmede ofset baskı sistemine alternatif olan dijital baskı, üretim verimliliği, maliyet ve kalite açısından önemli gelişmeler sergiliyor. Ofset, dijital baskı makinelerinde gelişen renk verimliliği ile flekso baskı ile rekabete girmiştir. Dijital baskı makineleri ile kaliteli ve farklı uygulamalar yapılabilmektedir. Bu (perdeleme) işleminin gerçekleştirilebilmesi için sistemde kullanılan cihaz ve makinelerin görülebildiği veya üretebildiği renk evreninin sınırlarının bilinmesi gerekmektedir. Bu çalışmada, dijital baskıda kullanılan ekran yöntemlerinin seçimi değiştirilerek renkler ile renk tutarlılığı arasındaki fark ve renk değerleri, nokta kazancı gibi temel ölçümler değerlendirilmiştir. Tarama yapısı değişkeninin neden olduğu farklılıklar grafik ve tablolarla gösterilmiş ve önerilerde bulunulmuştur. Dijital baskıda eleme yapılarındaki değişimin nokta şişmesi, yoğunluk ve renkte farklılıklar yarattığı tespit edilmiştir.

Anahtar Kelimeler:

Dijital Baskı, nokta kazancı, renk, baskı kalitesi

Investigation of the Effect of Different Screening Methods on Print Quality in Digital Printing System

Digital printing is the process of printing the designs and photos prepared in computer environment with advanced printing technologies on different materials in a high quality and fast way. The digital printing system, which is increasing its effectiveness today, has taken great steps with technology since the first years of its existence and has started to have a voice in the sector for the last ten years. The digital printing, which is an alternative to the offset printing system in making design a product, exhibits significant improvements in terms of production efficiency, cost and quality. Offset has become competitive with flexo printing with the developing color efficiency in digital printing machines. High quality and different applications can be made with digital printing machines. In order to achieve this (screening) process, it is necessary to know the boundaries of the color universe that can be seen or produced by the devices and machines used in the system. In this study, the difference between colors and color consistency and basic measurements such as color values, dot gain were evaluated by changing the selection of screen methods used in digital printing. The differences caused by the screening structure variable have been shown with graphics and tables, then suggestions have been made. It has been determined that the change in the screening structures in digital printing creates differences in dot swelling, density and color.
