Effect of Ink, Substrate, and Target Line Width on Quality of Lines Printed Using a piezo- electric Inkjet Printer

The study is concerned with the image quality analysis of inkjet lines printed on substrates. ISO 24790 compliant lines are designed and printed on a substrate with a drop-on- demand inkjet printer. This study analyzes three print quality attributes of line: width, blurriness, and raggedness. The research used cyan, magnetic and standard inks to print the same design on various substrates having differences in gloss and texture. The chosen inks were measured using a rheometer to determine a viscosity range. The effects of substrate structural parameters, such as texture, finishing, weight, and ink type on line quality, are discussed. The printed lines were measured using a charged coupled device camera. The print attributes were measured, and statistical analysis was conducted.

Mihir Ravindra Choudhari obtained his bachelors in Electronics and Tele-Communications Engineering at Savitribai Phule Pune University in India in 2015. He has recently completed his masters in Print Media at the Rochester Institute of Technology in May 2019. He worked keenly on the Inkjet printing technology with a focus on the inks used in graphic communication and how the print quality is affected because of the substrate texture. Currently he is working as an Artwork & Print Production Engineer at 3M Company, San Antonio,TX. As a print production engineer he is helping the company’s labeling team to improve their workflow efficiency and also managing the labeling requirements. His interests include inkjet, materials included in inkjet, conductive printing, workflows in graphic communication, color management in graphic arts and printing in regulated industry(Medical).
