Abstract This work investigates which factors and interactions are more influential in the inkjet printing process of conductive poly (3, 4-ethylenedioxythiophene):poly (styrenesulfonate) patterns. The chosen experimental design is an L16 Taguchi experiment with seven different two levels each eight interactions. studied printhead voltage, print resolution, substrate temperature, treatment, hei...

Dip-pen nanolithography (DPN) is a tip-based direct print technique widely used in nanofabrication applications. DPN is typically performed using Atomic force microscopes (AFM). In DPN, the nano-sized tip of the AFM is coated with a layer of ink molecules of interest, and traversed over a suitable substrate to print the desired pattern. Despite developments in recent years, DPN is still perform...

A survey of digital print providers in the U.S was conducted to identify constraints and potential solutions for improved performance and quality of digitally printed papers. In printers’ decisions about which paper to purchase, the key factors were identified as runnability and print quality. The leading paper characteristics considered when making a purchase were found to be toner/ink adhesio...

The existing palm-print verification schemes have demonstrated good verification performance when identity claims have to be verified based on palm-print images of adequate quality (e.g., acquired in controlled illumination conditions, free from distortions caused by the pressure applied to the surface of the scanner, etc.). However, most of these schemes struggle with their verification perfor...

Machine learning methods are increasingly being used to solve real-world problems in the society. Often, the complexity of the methods are well hidden for users. However, integrating machine learning methods in real-world applications is not a straightforward process and requires knowledge both about the methods and domain knowledge of the problem. Two such domains are colour print quality asse...

A methodology for automated analysis of print quality in inkjet printing has been developed and tested on 32 commercially available media. The methodology is based on an understanding of the phenomenology of ink-media interactions and their impact on print quality and user perception. The automated print quality analysis system described has a comprehensive set of built-in tools for quantifying...
