Effect of oil based CMYK process inks on tearing characteristics of paper
Abstract: Every day we use many different kinds of printed materials exposed to tearing stresses. Interactions between paper and printing inks affect the inter-fiber bonds, accordingly the tearing properties of paper. This study was carried out to determine the tearing resistance properties of papers printed with solid tone offset inks, using Cyan, Magenta, Yellow, Black process series. The static tearing resistance of paper was determined by universal tensile testing device and tearing strength patterns was examined. Decrease of tear resistance and relatively close tear index ratios (cross direction / machine direction) was observed for printed papers. Application of solid tone inks increases the force required for initiation of tearing of papers.
Keywords: Tearing resistance, tearing with tensile tester, CMYK ink
Yağ bazlı CMYK proses mürekkeplerinin kağıdın yırtılma özellikleri üzerindeki etkisi
Özet: Her gün, yırtılma stresine maruz kalan çok farklı türlerde basılı materyaller kullanıyoruz. Kağıt ve baskı mürekkepleri arasındaki etkileşimler, elyaf içerisindeki bağları ve bunun neticesinde de kağıdın yırtılma özelliklerini etkiler. Bu çalışma, Camgöbeği, Macenta, Sarı ve Siyah proses serileri kullanılarak yoğun tonlu ofset mürekkeplerle baskı yapılan kağıtların yırtılma direncini belirlemek üzere yürütülmüştür. Kağıdın statik yırtılma direnci, evrensel çekme testi cihazı kullanılarak belirlenmiştir ve yırtılma direnci modelleri incelenmiştir. Basılı kağıtlarda yırtılma direncinin azalması ve nispeten yakın yırtılma endeksi oranları (çapraz yön/makine yönü) gözlemlenmiştir. Yoğun tonlu mürekkeplerin uygulanması, kağıtların yırtılmaya başlaması için gerekli olan gücü arttırmaktadır.
Anahtar kelimeler: Yırtılma direnci, çekme testi cihazı ile yırtılma, CMYK mürekkebi
