Selection and determination of the effective factors on packaging paper print quality using design of experiments

Abstract

In present competitive world, packaging has a significant effect on the rate of sale. Unfortunately, in Iran's packaging industry, the variation of printing methods is too low which leads to reduction in quality of packing and the amount of sale. Therefore, some manufactures prefer to send out their products to be packed. In this paper, to achieve an acceptable quality in printing the paper packaging, four factors of paper roughness, ink viscosity, grindometer (unresolved droplets of ink particles) ink and paper thickness were studied. Fractional factorial designs are used to evaluate the factors. Each factor is investigated in two levels. Based on obtained results, all the factors have a significant impact on response.
