S I G N & D I G I T A L G R A P H I C S • May 2018 • 39 lot of competition with hybrids by taking this approach. One of the most exciting applications we've seen is dimensional printing where the UV inks are built up on the substrate similar to a 3D printer. This technique can produce everything from subtle textures like woodgrain, alli- gator skin, embossed type, logos, etc. to even the printing of braille signs accurate enough to be ADA compliant." He adds that the best-suited appli- cations for hybrid UV printers, in his opinion, are the printing of square/rect- angular boards. It's All About the Ink Mimaki's Maxwell believes that advancements in inks are what's broad- ening the flatbed's flexibility. "Most UV ink in flatbeds is limited to a few years of life expectancy for indoor applications and outdoor life expectancy is generally calculated in months, but that's changing as ink technology advances. Even a few years ago, flatbeds were limited to mate- rials that were not heat sensitive because of the common use of halide lamps for curing." He explains that as technology pro- gressed and created L E D -based U V curing lamps, the ink chemistry has advanced with it and was modified to be able to be cured via LED. "Mimaki was a pioneer in UV-LED ink that opened up the ability to print onto heat-sensitive materials like PVC and thin films with higher quality. Or rigid materials like Dibond that would have its core melt and warp under the old halide cure lamps." Maxwell says the best applications for true LED-UV flatbeds include PVC sheeting, foam core, acrylic, and compos- ite metal. "True flatbeds have also gained favor with industrial-focused printers. The ability to do multiple objects with full customization on each piece is attrac- tive to these types of providers, and the additional area enables more productiv- ity," he concludes.
