T16-Creating Added Value to your Inks through the Addition of Covert and Forensic Security Materials, Neil Ivey, Brandwatch Technologies
Counterfeit goods have grown from a shadow industry that wasn’t openly discussed to a world-wide crisis that costs millions of jobs and hundreds of billions of dollars. The threat posed by counterfeit goods is not limited to fake watches that stop working after a few weeks; they are used by terrorists to cross borders, fund organized crime, and pose threats to unknowing consumers of pharmaceuticals and even airline passengers. Many of these counterfeits could be identified quickly, easily, and cost-effectively by integrating covert and forensic security materials into printing inks. We will explore the options available to printing ink manufacturers, which enable you to provide added value to your customers and your customer’s customers.
8:45am - 9:30am
T17- 3D Printing on 2D Surfaces- Matt Hirsch, Lumii
This exciting new technology session will focus on the latest developments in 3D printing like hologram-like prints using a standard printer, media, and ink. This presentation will cover a unique computational approach to printing, and provide background on concepts in optics and light field imaging that make the technology possible.
9:30 - 9:45am - Break
9:45 - 10:30am
T18-Rapid FTIR Press‑Side Testing to Confirm the Cure of UV/EB Coatings for Packaging Applications, Elizabeth Leeper, Daybreak Technology
UV and EB curable coatings provide very desirable appearance and resistance properties for surface printed packaging. Coatings suitable for indirect food packaging applications are available; however, they must be properly cured in order to achieve the desired low migration properties. Migration testing using food simulants requires testing by an outside lab and takes at least several days to get results. Testing using reflective (ATR) FTIR spectroscopy can be accomplished in a few minutes and works with almost any substrate. FTIR equipment is relatively low cost and easy to operate and maintain. The method was validated by correlating FTIR results with migration testing on EB coatings cured with a series of dose levels.
10:30 - 11:15am
T19- An Expanded Gamut Ink Set for High-Speed Inkjet Printing on Flexible Films and Folding Cartons, Douglas Bugner Kodak
Expanded gamut ink sets generally comprise up to three chromatic process color inks in addition to a standard cyan, magenta, yellow, and black (CMYK) set of inks. The main advantage of using a 5-, 6-, or 7-color ink set is the ability to significantly expand the number of available colors that can be reproduced over a basic CMYK ink set. For packaging applications, this provides an option to accurately match important brand colors on press without the need to formulate specific spot color inks for each print job. In addition, it is also possible to minimize the total amount of ink used by substituting a single drop of one of the additional colors, e.g., blue, for two drops or layers of a standard CMYK ink set, e.g., cyan plus magenta. The choice of the specific color(s) of the added ink(s), as well as the order of laydown of the expanded gamut ink set, can have a measurable impact on the resulting color gamut. The choice of a pre- and post-treatments can also make significant contributions to the overall print quality and color gamut. This paper will describe the methodology and measurements that were used to select the specific nanoparticle pigment dispersions and ink colors that comprise the Kodak 7-color expanded gamut ink set which was recently showcased at drupa 2016 printing at 150 mpm on white BOPP label stock.
11:15am - 12:00pm
T20- Vegetable Oils in Graphic Arts: An Overview with a Focus on Tung Oil and Castor Oil, Blake Hansen
Vegetable oils have been vehicles for inks since time began. The presentation reviews the range of vegetable oils and derivatives used in graphic arts today, then looks specifically at Tung Oil and Castor Oil, going into detail on the production, markets, technical properties, and product applications of these industrial, veg oil workhorses. What are the reasons for the relative costs of different vegetable oils? What are the unique chemistries of tung oil and castor oil that give them their value? The presentation delves into the utilitarian (and slightly exotic) worlds of castor and tung.
