Palm Yağı Katkılı Mürekkeplerin Baskı Kalitesine Etkisinin Belirlenmesi

Öz

Ofset baskı mürekkepleri temel olarak pigment, çözücü yağ ve reçinelerden oluşmaktadır. Mürekkep üretimindeki gelişmelerin doğa dostu kaynaklara yönelmesi, baskı mürekkeplerinde kullanılan mineral bazlı yağların yerini bitkisel bazlı kaynaklardan elde edilen yağlara bırakmasını gerektirmiştir. Yağ elde etmede kullanılan pek çok endüstriyel bitki bulunmaktadır. Fakat bunların ofset baskı mürekkeplerinde kullanılabilmeleri için çeşitli gereksinimler bulunmaktadır. Bu gereksinimler baskı kalitesinin yanı sıra verimlilik ve ekonomikliktir. Palm yağı geniş kullanım alanına sahip olması sebebiyle bol miktarda üretilen ve ekonomik avantajı olan bir yağdır. Bitkisel yağları, petrol türevi mineral yağlar yerine matbaa mürekkeplerine eklemek, son zamanlarda hem sağlıklı hem de çevresel nedenlerden dolayı popüler bir uygulamadır. Matbaa mürekkeplerinde soya ve benzeri bitkisel yağlar ile ilgili yapılan pek çok araştırma mevcuttur fakat palm yağının Cold-Set mürekkeplerde kullanımı ile ilgili çalışmalar yeterince yapılmamıştır. Bu nedenle, çalışmanın amacı palm yağının gazete mürekkepleri üzerindeki etkisini belirlemektir. Çalışmada, mineral yağ ve palm yağı ile hazırlanan farklı mürekkepler kullanılmıştır. Palm yağı, toplam miktardaki mineral yağın üç farklı oranda (%3, %6, %10) eklemiştir. Bu farklı oranlar için viskozite, akma gerilmesi, akış, parlaklık, sürtünme direnci vb. palm yağının Cold-Set mürekkepler için kullanılabileceği gösterilmiştir.

Determination Of The Effect Of Palm Oil İnk On Print Quality

Öz

Offset printing inks mainly consist of pigment, solvent oil and resins. The development of ink production to environmentally friendly resources has required that mineral-based oils used in printing inks be replaced by oils derived from plant-based sources. There are many industrial plants used for oil production. However, there are various requirements for their use in offset printing inks. These requirements are productivity and economics as well as print quality. Palm oil is an oil that is produced in abundant quantity and has economical advantage because it has wide usage area. Adding vegetable oils to printing ink instead of petroleum derived mineral oil is a popular application recently for both healthy and environmental reasons. There are a lot of studies about printing soya and similar vegetable oils in printing inks, but studies on the use of palm oil in Cold-Set ink have not been done sufficiently. For this reason, the purpose of the study is to determine the effect of palm oil on newspaper ink. Different inks prepared with mineral oil and palm oil were used in the study. Palm oil has three different proportions (3%, 6%, 10%) of total mineral oil. For these different ratios, viscosity, yield stress, flow, gloss, friction resistance, etc. It has been shown that palm oil can be used for Cold-Set ink.
