X-Rite Inc., the maker of color measuring equipment, has developed xDNA technology that helps solve mismatch problems with parts that have a “sparkle” finish, such as matching bumper fascia and body panels.
Measuring and matching sparkle finishes has been a challenge since the automotive industry introduced metallic flake, pearlescent and other special finishes in the 1970s, according to a X-Rite news release.
The company said xDNA can indicate whether the problem happened on the production floor, or in formulating the coating.
X-Rite's xDNA can be used for a coating applied to a plastic substrate, as well as for ingredients mixed with resin to give a sparkle appearance throughout the part.
“With today's introduction, X-Rite is giving automakers and their suppliers the appropriate tool to distinguish characteristics of effect paints that can't even be detected — much less analyzed — by other systems,” said Brian Teunis, market manager for X-Rite's Industrial Color & Appearance Division.
The xDNA name emphasizes that each paint has a unique, three-dimensional mathematical model, a “DNA,” Teunis said in the release. The formal name is Dynamic Numerical Analysis.
X-Rite said the new system solved in just three days a mismatch problem between an un¼identified automotive supplier and a European automaker over a silver metallic-color paint of bumper fascia and body panels — after they spent two months trying to resolve the issue using other measurement equipment, said X-Rite of Grand Rapids, Mich.
