Real-Time Image Compensation and Memory Arbitration for Ink-Jet Patterning on Roll-to-Roll System
Abstract:To brew ink-jet printing (IJP) technology instead of traditional processes like spinning, screen printing, photolithography, and laser printing, used for semiconductor and display field, what is the obstacle before make mass production? The image compensation for printed thickness and resolution modulation control is the highest priority due to they dominate the device performance, especially for the roll-to-roll fabrication process. In this study, we tried to construct a novel algorithm to real-time calculate methodology to compensate the image distortion due to the thermal process and web delivery stress. Besides, this paper proposed a novel image trimming method based on the spreading factor between the liquid-solid interface and calculated image distortion, to real-time transfer the original image to a printing raster image data. In details, the trimming method included the procedure of pattern identification and locating, image separation, seamless image merge, image boundary compensation, image trimming on spreading factor, and image reconstruction, and the filtering method included the local characteristic of boundary inspection with defined correcting function and varied filtering pattern applied to inner field of boundary. To correct the landing position, this article designed new algorithm memory arbitration for the inconsistent between nozzle physical arrangement and printing data by rearranging the data format, to reduce the dispensing landing deviation.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
