1-888 -478-0998 No Plate Lifting No Plate Mounting Perfect Registration Every time. Discover Your New Media Source for Seamless Imaging Photopolymer Sleeves Laser Engravable Elastomers The use of LUX with MicroCell not only improves the maximum per- formance available from MicroCell patterns, it increases the number of MicroCell patterns that work. The latest update of MicroCell, called Pixel+, has taken the capabilities of this technology to even greater levels. This improve- ment affects both SID and color gamut. Figure 7 shows the color gamut increase that is possible compared to standard digital plates. ICC profiles for this graph were gathered from dot gain compensated IT8.7/4 targets printed at Fox Valley Technical College on white polyester film. The gamut increase is not only due to the higher solid ink densities, which Pixel + provides, but also due to more effective ink trapping of color over- prints. Significant gains in trapped color saturation throughout the tonal range are possible. The sophistication and capability of MicroCell + LUX are the ultimate in solid color reproduction, but reaching this level of performance does require investment in hardware, software, and testing to find the best combination of patterns for a given application. MicroCell patterns work better on some substrates than others, so it is strongly recommended that one study the options available and test directly before investing in this advanced imag- ing technology. But as the color gamut in Figure 7 shows, when done properly, the combination of MicroCell Pixel+ and LUX delivers color reproduction capabilities that are state-of-the-art. SUMMARY Today, the platemaker and printer have options to select from when choos- ing a method of increasing SID and improving the quality of their solid print. Three plate-based technologies avail- able for doing so are compared in the table positioned at the start of this ar- ticle. With these options available, flexo platemakers and printers now have a broad arsenal of technologies at their disposal to produce the most vibrant and consistent colors possible. n About the Authors: Dr. Timothy Gotsick is the Vice president of technology for Mac- Dermid Printing Solutions.
