The Printing Applications Laboratory at Rochester Institute of Technology has developed a new series of webinars in such areas as color printing fundamentals, matching proof and press, and lithographic troubleshooting. Faculty and technical staff from RIT’s School of Print Media and RIT’s Printing Applications Laboratory are leading these online training sessions.
The webinars are designed to complement RIT’s on-campus seminars and training sessions. Those who register for one of the online sessions and the corresponding on-campus seminar will get the webinar fee deducted from the cost of the on-campus seminar. Registrants will also receive an additional 10% discount off the total full program fee.

The following is a list of upcoming webinars:
Matching Proof and Press
Feb. 17, 3-4 p.m. EST
It’s an age-old problem in which the customer signs off on a proof and then the press can’t match it. Make-ready times are long, paper waste is high and so is the frustration as press operators chase ink densities up and down and customers become increasingly more disappointed with color variation and late deliveries. This webinar will explain the process of achieving better proof-to-press color matching. Topics of discussion will include calibrating press and proofer to a standard reference condition by various methods (near neutral, G7), fingerprinting, characterizing and profiling a press and proof, measurements necessary for process control (densitometric & colorimetric) and analyzing and interpreting color measurement data. This webinar serves an introduction to the full four-day seminar scheduled at RIT’s Printing Applications Laboratory March 17-20.
Lithographic Relationships and Variables
Feb. 26, 3-4 p.m. EST
This webinar is designed to familiarize participants with the principles and language of offset lithography such as plates, fountain solution, blankets, rollers, ink and paper. Discussion will center on the machines, raw materials, supplies and methods used in offset lithography and how changes in these variables may influence print quality and productivity. This Webinar serves as an introduction to a two-and-a-half-day seminar scheduled at RIT’s Printing Applications Laboratory March 25-27.
Color Printing Fundamentals
March 6, 3-4 p.m. EST
This webinar introduces participants to the fundamentals of color theory and perception as applied in the context of the print production environment. It is designed to help demystify why the colors on the monitor rarely match those in print and to set the framework for creating an environment where color is predictable and consistent. This serves as an introduction to a two-and-a-half Color Printing Fundamentals seminar scheduled at RIT’s Printing Applications Laboratory April 6-8.
March 16, 3-4 p.m. EST
Ghosting, picking, piling, doubling are just a few of the problems that can challenge even the most experience lithographic printer. This webinar will discuss a systematic approach to troubleshooting and give tips on the proper troubleshooting tools and techniques to help correctly identify the problem, fix it quickly and prevent it from happening again. The two-and-a-half day on-campus seminar is scheduled at RIT’s Printing Applications Laboratory April 15-17.
Color Printing Process Control
March 23, 3-4 p.m. EST
This webinar will discuss the basic concepts of how process control is used to achieve repeatable and predictable color reproduction in printing. Without a controlled and stable process, performance results are unpredictable, causing late deliveries, excessive waste, poor productivity and efficiency, and sub-standard quality. Topics of discussion will include: how to quantify variation with numerical and graphical tools such as histograms, timeplots and scatter diagrams, how to determine process performance with spatial uniformity and temporal consistency, and how to assess process capability and product conformance with Cp and Cpk metrics. The two-and-a-half day seminar is scheduled at RIT’s Printing Applications Laboratory on April 22-24.
