FLEXO Magazine : May 2012
The most reliable and repeatable methods of measurement were electronic and Microfax. Instruments proved they were accurate. Nominal values differed. As stated before, this initial project is considered complete. There are two new projects being introduced to take this investigation even further. The first is a Gauge R&R Study of Open Cell Structure. The first thing that team members need to accomplish is to determine the commercial cell shape structures they would like to include in the next phase. At this time, micrographs, cell descriptions are being gathered and reviewed by the team members. The team will need to secure rolls to measure after the cell structures are finalized. Associ- ates will then use the same measurement devices as the first study. The Executive Committee recently approved the charter for this project. The Extended Gamut Team, led by Danny Rich, Sun Chemical, has worked extremely hard to gather data, and analyze, analyze, analyze. Since the beginning of the project the adoption of Extended Gamut in production has increased significantly. The team had some predictions of results, which were validated by the study. Outcomes also validated the mono pigmented inks show greater increases in gamut than mixed pigmented inks. The team is finishing the compilation of pressrun data in preparation to write and submit its final report for publication. One of the things the team will do is share its findings with the FIRST committee to further optimize pigment selection and optimization. The results of this study and new insights may lead to a follow-up study to document the spot colors that may be contained in the expanded gamut volume. The ISO Ink Standard Team, led by Jay Sperry, HAVI Global Solutions, consolidated ISO ink targets from flexo standard 2846-5 to 2846-1 . The project also intends to verify that ink suppliers can economically provide process color inks to a common standard under methods defined in 2846-5 . Unfortunately, this project has been on hold as the team looks for a substrate that meets the proposed standard. The good news is that a substrate may have been identified during the working session at Forum. The team intends to investigate and look toward restarting the project. The Standards Working Group, led by Hilliard (see side- bar), helps facilitate the review of proposed standards affect- ing our industry, provide relevant feedback and communicate how these standards may affect the membership in daily production. The charter of this organization is “to insure that the flexographic printing industry is duly represented in the development of relevant standards, and to stay current with any standards additions or revisions.” Many dedicated members take an active role in standards review for our industry. It is a monumental task to remain cur- rent. This team will work to gather information, summarize its importance and gain input from our industry experts. The FQC Session at Forum also contained three research initiatives. PJ Fronczkiewicz, Flint Group, led the session with his presentation titled “Ever Wonder What Would Happen If... Pushing the Limits of Bad Plates.” Fronczkiewicz’s research included the comparison of plates using the very latest technology (flat top dots, surface screening, high resolution) 120125_3.875x10.875_NExT_US.indd 1 25.01.2012 08:43:16
