“…In literature, the researchers (Chiu et al , 2013; Kun et al , 2006; Pan et al , 2004) tried to identify and optimize the process parameters in screen printing and found that screen mesh count, and so the mesh thickness were the key to determine the amount of the ink printed. Tsai (2011) developed a Taguchi model for ink volume optimization in screen printing and found that the geometric design of the screen, aperture size and screen mesh thickness were the major parameters.…”

Purpose The purpose of this paper is to optimize the key parameters (mesh count, paper type and ink type) in screen printing, which are affecting the printed ink volume. The objective of the optimization was to maximize the color reliability by decreasing the color difference (ΔE value) of the prints while minimizing the ink consumption. Screen printing is still dominating the printing industry to make cost-effective production when high volumes are needed. Design/methodology/approach The experiment was designed using the Taguchi method, and the samples were prepared with screen-printing by using the standard squeegee angle and pressure. The effect of mesh count, ink type and paper type on ink consumption was evaluated with using analysis of variances and main effects plots of S/N ratio and standard deviation. Findings The factors ink type, paper type and mesh count were found significant for ink consumption due to their Probability (P) values which were lower than 0.05. It was determined that the mesh count was the most critical variable with the analysis of variance. The analysis showed that the selection of an optimum mesh count was the key to controlling the amount of the deposited ink. Although mesh counts were inversely proportional with the ink consumptions, they did not affect the color differences as expected. Originality/value The optimization of process parameters, that are most effective on the print quality, is necessary to minimize the ink usage and lower the costs and environmental impact without exceeding the desired ΔE value limits.
