Determination Of The Effect Of Palm Oil ？nk On Print Quality

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
