what appears simple is often Qualitaly! M5 The new GIDUE “Digital” revolution in the Labels and Packaging industry, “digital” micro-runs, long-runs, The first version of the software was released in November 2011. Black says that while it attracted a large amount of interest from potential customers, one complaint became a common refrain. “SpotOn! Flexo was a stand alone applica- tion with a single database, where the reference colors and press measurements were stored,” Black says. “ T his meant if you wanted to have multiple copies of the software at each press, there was no way to share the database. ” The solution, both companies discovered, was a client server based software that allowed multiple users to share the same database. It required extensive work—essentially rebuilding the product, Black says—but was a necessary step. Nearly a year later, in September 2012, this new version of SpotOn! was launched. Subsequent specific customer requests have been addressed in incremental revisions since then. INSIDE THE SOFTWARE SpotOn! Flexo is a color analysis software tool that uses a “Predictive Analysis” algorithm to determine the best ink density to achieve optimum color reproduction. Predictive Analysis is an adaptation of the Beer-Lambert Law, which is a relationship of ink film thickness and substrate white point, as related to L*C*h°. Unlike CMYK colors that have both ISO standards and specifications, like Flexographic Image Repro- duction Specifications & Tolerances (FIRST), that suggest ink density starting points, the companies wrote in their awards submission, “Color reference guides and ink drawdowns come to press with no ink density information.” Furthermore, flexo’s color control options are limited: • Increase ink density • Decrease ink density • Increase pressure or impression • Decrease pressure or impression SpotOn! creates what APR refers to as Optimal Ink Density. The measurement informs an operator if an acceptable spot color match can be achieved or improved with an ink density correction. The software also can be used in the ink lab before going to press, to see if an ink can successfully be matched ahead of time. Black says that the software “compares the spectral data of a color measured on a press pull to the spectral data of the reference color,” with the aid of a spec- trophotometer. Spectral data then provides op- timal ink density Exclusively from...
