Print Research & Imaging Systems Modeling Laboratory (PRISM) 1 June 2008-31 May 2009 Laboratory Director's Comments: Dr. Marcos Esterman Overview The PRISM Lab continues to focus on three key areas; Print Image Quality, Printing Technology Characterization and Development, and Sustainability in Printing. In November of 2008, PRISM hosted its second research round-table which included participation from Eastman Kodak, Hewlett-Packard, Ricoh and Xerox. The focus of the meeting was to discuss challenges of incorporating sustainability into business, and in particular, technology decision-making. In recognition of the importance of sustainable printing as its own research area, the Sustainable Print Systems Laboratory (SPSL) was founded in 2008 by Marcos Esterman and Sandra Rothenberg (from the Saunders College of Business). The obvious close link with PRISM and the SPSL will remain. Additional, infrastructure has been added to characterize and better understand Electrophotographic process physics through the generous donation of a linear test-bed by Eastman Kodak. This test-bed has already been a vehicle for fostering industry collaboration between local print manufacturers and will form the center-piece for further research of interest to the industry as a whole. With this added infrastructure coupled with previously developed infrastructure, PRISM is positioning itself to be a valuable resource for developing new empirical and analytical knowledge and enabling more sustainable printing. PRISM continues to use sponsored research projects to support student projects. These have included both individual thesis projects and multi-disciplinary team projects through the Kate Gleason College of Engineering.

Marcos Esterman was the conference chair for the 2009 ASME International Design Engineering and Technical Conferences Design for Manufacturability and Life-Cycle Conference (DFMLC) and will be the DFMLC secretary for the 2009 – 2010 academic year. Graduate Thesis Projects: PRISM's contribution to academic degree programs has been focused on increasing student opportunities in print imaging technology. Toward this end we have supported thesis projects for several graduate students as described below. Mr. Fermin Colon-Lopez: Ph.D. Project Title "A model of electrophotographic printing that is independent of the halftone algorithm". Mr. Colon-Lopez has been a part time graduate student in CIS for many years, earned a MS in Imaging Science, and is expected to complete his dissertation by the end of the current academic year. Mr. Carl Smith: M.S. Project Title "The Analysis of Specular Reflections from Printed Surfaces". Mr. Smith is a graduate student in CIS and is working with PRISM on the development of instrumentation and analytical protocols for the optical characterization of printed images. Mr. Alvaro Rojas: M.S. Project Title "A Selection Framework for Derivative Product in Changing Platforms ". Mr. Rojas completed his MS Thesis in the Industrial and Systems Engineering in the summer of 2008. While his thesis work is not directly related to PRISM, Mr. Rojas had been the lead research assistant on development of the fuser test-beds. He has taken the feasibility prototypes developed by the Multidisciplinary Design program and made them working lab instruments. Mr. Jared Russell: M.S. Project Title "An Optimization Approach to PlantController Co-Design ". Mr. Russell graduated with a dual degree BS/MS in Computer Engineering in the summer of 2009. His work with PRISM developed the control systems for both fuser-test beds, and was the basis of his thesis work. Ms. Alicia Tejada Abreu: M.S. Project Title: “Explaining Print Media Paper Consumption Patterns through a System Dynamics Approach”. Ms. Tejada Abreu is a first year PhD student in Golisano Institute for Sustainability and a researcher in the PRIM lab. He long-term research focus is on the role that technology can play to enable reduced media consumption in the print industry. Her MS thesis is expected to be complete in the Fall 2009, where she is modeling historical media consumption patterns so that we can understand the relevant dynamics that have led to some counter-intuitive behavior (e.g. why is the paperless office an elusive goal). Ms. Suparna Kishore Kalghatgi: M.S. Project Title: TBD. Ms. Kalghatgi is a second year graduate student in Industrial and Systems Engineering and will be working with PRISM to support the Sherwin/Williams project. The goal of this project is to provide Sherwin/Williams with quantitative information about the material parameters that must be controlled to minimize the "touch-up" effect in painted surfaces, to provide guidance on how to measure those parameters physically, and to use psychophysical experimental techniques to generate models for predicting changes in appearance. Ms. Angelica Li: M.S. Project Title: Implementing Sustainability in Commercial Lithographic Printing Operations - A Workflows Approach to Identifying Sustainable Actions”. Ms. Li is a graduate student in School of Print Media. This work is supervised by Franziska Frey and Marcos Esterman. This work will contribute better understanding of the impact that workflow decisions have on the sustainability of printing. Masters in Product Development: Marcos Esterman is on the teaching faculty of the Masters in Product Development Program. One of his roles is to supervise the capstone thesis of a project team of 2-3 students. In the past two years, the projects have been focused on gaining increased understanding of the role that R&D plays in the development of sustainable technologies. In particular, the topics of these capstones have been: “The Challenges in Incorporating Sustainability into Product Development” and “Enabling By-Product Exchanges through Product Development”. Undergraduate Projects: PRISM also has a commitment to provide research opportunities to undergraduates at RIT. Mr. Allan Liburd: Project Title: "Improvement of Java Code for the microgoniophotometer". This work was performed as a summer project in 2009. Previous work in PRISM has shown that a more thorough analysis of gloss can be accomplished with little additional effort using the RIT microgoniophotometer as compared to a traditional gloss meter. In order to improve the usability of this device, a Java program was previously developed to control and analyze the resulting images. The focus of this project was to debug and improve the existing code. Senior Undergraduate Engineering Design Projects: A particularly successful way in which the PRISM lab has contributed to RIT academic opportunity has been through the sponsorship of projects in the RIT Multidisciplinary Senior Design (MSD) Program. This is a program developed by the Kate Gleason College of Engineering to offer multidisciplinary capstone projects. These projects challenge engineering students from a variety of technical disciplines to work together as a team to accomplish a complex, practical project. Professor Esterman is a member of the KGCOE MSD teaching team and steering committee as well as an Extended Faculty member in CIS and has devoted a significant amount of time to the development of this unique educational opportunity. Over the past year, the PRISM lab sponsored one project and was involved in advisory capacity on a second. Project Title: "The Development of an Electrophotographic Development and Transfer Station”. This Senior Design project was sponsored by the PRISM lab to make an existing electrophotographic development and transfer station function and to improve its usability. The design team involved eight senior engineering students in KGCOE including three from mechanical engineering, three from electrical engineering, one from computer engineering and one from industrial and systems engineering. Project Title: “Low Energy Printing (Xerox)”. This project, sponsored and managed by Xerox, challenged the senior design team to re-consider the design of an extremely low power, non-thermal fusing system. PRISM personnel served an advisory role. This project is leading to an active collaboration in low energy printing. In the course of this project, the team members were to identify performance specifications and critical parameters for potential adaptation to a commercially available monochrome printer and to initiate a prototype for market evaluation. The team consisted of two mechanical engineers, one electrical engineer and one industrial and systems engineer. Funded Research: (totaling $135,000) Funding (both monetary and equipment donations) over the past year has been primarily from Hewlett-Packard, Xerox, Eastman Kodak, Sherwin/Williams, and the Print Industry Center. Specific projects are shown below Evaluating the Value of Print on Screen versus on Paper Using Eye-Tracking -Susan Farnand, PI. The objective of this print versus display project is to develop a methodology for and to conduct initial experimentation examining the differences in the efficacy of magazine advertising on screen relative to the printed page, with particular attention to the advantages and disadvantages of print. Longer term, it is intended that the experimental methodology will be used to explore possible differences in efficacy of print on paper versus display and which characteristics of these media are particularly relevant when comparing the consumption of information on paper versus on screen. Development of this methodology will involve an assessment of evaluation criteria including information retention, distribution of visual gaze as measured by eyetrackers, time needed and eye movements that occur when detecting image differences, and visual comfort. The initial phase of the project will involve using eyetrackers to monitor eye movements when looking at a photo booklet either on screen or in print. Areas of the images fixated for each media will be recorded and compared. Information retention will be assessed by having participants answer questions about the images that were viewed. The time spent with each medium will also be recorded. Measurement, Modeling and Perception of Painted Surfaces -- Jim Ferwerda PI, Jon Arney Co-PI, Susan Farnand, Co-PI. The project will apply RIT's unique capabilities in (1) measurement of optical surface properties, (2) modeling and simulation of surface appearance based on physical measurements (3) psychometric analysis and prediction of appearance. Using samples provided by Sherwin-Williams, we will use our unique microgoniophotometer to capture spatially resolved BRDF data inside, outside and at the edges of the touch up region. These data will be represented as calibrated reflectance images taken under controlled lighting conditions. We will then analyze these images using multiscale image processing methods to determine if and how the regions differ in texture at different spatial frequencies. This analysis will give us the data we need to understand what particular surface properties are contributing to the measured (by the glossmeter) and visual gloss differences. We anticipate that different formulations and application methods will lead to significant differences in the spatial frequency statistics that may be important with respect to the measured and observed gloss differences. Design and Initial Approach for a Print Energy Life-cycle Decision Tool-- Marcos Esterman Co-PI, Sandra Rothenberg Co-PI, Scott Hawker, Co-PI. Information technology holds tremendous potential to help consumers and firms make more sustainable choices by providing information at key decision points. As one example, there are a number of software programs that help calculate and summarize environmental metrics for various products and processes. Surprisingly, while many printers are moving into the IT arena, the technology has not been fully utilized. For the most part, there is a lack of knowledge on the part of the consumer on the sustainability impacts of their communication decisions. Thus, this work outlines a prototype decision tool which could be used to estimate the energy consumption of printing a given document, by analyzing the user’s requirements for the print job, the printer selected and the corresponding life-cycle criteria for these elements. A Survey into Sustainability Metrics and Methods -- Marcos Esterman Co-PI, Sandra Rothenberg, Co-PI. The goal of this research it to perform a survey into metrics and methods employed by the printing industry to measure, track and integrate sustainability into their business practices. In addition, it is also recognized by the PI’s that a great deal of work has been conducted in this area by the print industry, but that a proper inventory of the current state of the art is lacking. Therefore, the focus of this work is to define the research roadmap that will be required to develop this inventory and execute the first phase of that inventory. In addition to the inherent value of just the described service, this work would serve as the foundation for the future development of a printing value chain test-bed envisioned by the PI’s. Implementation of an Electrophotographic Linear Test-Bed -- Marcos Esterman CoPI, Jonathan Arney Co-PI, Susan Farnand Co-PI. The proposed project will leverage resources from Eastman Kodak and Xerox to finish the development of an electrophotographic linear test-bed. This test-bed will be the centerpiece with which to perform informative experiments that will benefit a consortium of EP-based printer manufacturers, to develop education programs to train future electrophotographers, and to develop ideas for novel applications of EP. Benchmarking Art Image Interchange Cycles Image Quality Experimentation -Franziska Frey, PI and Susan Farnand. This project is being conducted to evaluate current practices in fine art image reproduction, determine the image quality generally achievable, and establish a suggested framework for art image interchange. Toward this end, experimentation is being conducted in which a set of objective targets and pieces of artwork in various media are being imaged by participating museums. Print files and guide prints will be delivered to the Rochester Institute of Technology where prints will be made and used as stimuli in psychometric testing to generate scales of image quality. The experimental results will be among the inputs used to construct a conceptual framework of the various types of imaging taking place in cultural institutions at present. Based on this framework, an image processing tool that incorporates appearance models that are adequate for the various working environments in cultural heritage institutions will be developed.
