Effect of Texture on Visual Perception of Color Lightness in Inkjet Printed Woven Textiles
The goal of this study is to understand the effect of texture on visual perception of color in inkjet printed woven textiles. Cotton woven samples were constructed with nine different weave structures. The surface characteristics of the samples were determined using the KES-F and profiling instruments. Each sample was digitally printed with identical squares of primary colors of cyan, magenta, and yellow and secondary colors of red, green, and blue. The amount of ink applied was controlled consistently with an image editing software. CIE L* values were calculated from the measured reflectance. For visual assessment, the rank order method was applied and 25 observers ranked the perceived texture and color lightness of each sample.
By employing the rank order method, a perceived visual texture scale was obtained statistically from the specified rankings. The scale of visual texture shows high correlation with the friction coefficient (MIU) and the mean deviation of the MIU (MMD). The roughness (SMD) was not correlated with the scale of visual texture. The surface measurements from the profiling instrument (Pa) are also correlated with the scale of visual texture. The scale of the perceived color lightness was estimated from the assessed rankings. The measured CIE L* values and the scale of perceived lightness have a linear relationship for the primary and secondary colors. The scale of the perceived texture and the CIE L* values showed a relatively good correlation, but the surface characteristics of the weave structure, such as highly oriented yarn on the surface, can affect the light reflectance differently.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
