All Rights Reserved of things the SH PE of things The unique shoulder profile of MacDermid’s LUX® flat-top dots yields superior print results. That’s why LUX has been installed at more than 170 sites worldwide. Consistent Print Quality The unique LUX dot shape reduces the effect of impression on dot gain, resulting in longer runs, more reliable color, and fewer stops for press adjustment. Easily Integrates into Current Platemaking Workflow This simple process is a complement to existing flexo technologies, can be used with all flexo lasers, and does not require modification to current equipment. An Experienced Partner LUX Platemaking and the expertise to make the most of it comes only from MacDermid — Start your journey with us.

Finished plate measurement devices confirm the finished plate dot size. They are extremely useful during the initial setup of digital plate systems. These devices are required to verify that plates are being made consistently across a single plate, across repeated platemaking activities or even across multiple platemaking locations. This is one of the final checks that can be performed on a plate before going to press. The final measurements encompass and can reflect all the vari- ables in the platemaking process. UVA light meters benchmark the intensity of the UV expo- sure units used for main and back exposures. Tracking these results lets users monitor the life expectancy of bulbs. By measuring and tracking the UVA output, users can continu- ally adjust exposure times to compensate for the bulb’s output dimming over time due to use. Procedures can be put in place to require a bulb change when output drops below a specified level. AutoMAtion & Process controL Technology has made process control easier and more streamlined. Current equipment is much more automated than before and most can transmit data to a computer or store it on a memory card. This means the operator doesn’t need to use pen and paper. Fewer steps leads to a better, less error-prone system. The more technology automates the workflow, the easier it is to implement process control. But there is a small caveat: Be- cause automation is generally more expensive, it takes more time for the initial set up and requires a bit of expertise. The take-away for good process control implementation is that it needs to be easy to understand, easy to do and come with a commitment from both operators and management. When everyone’s on board they will understand why process control works. When everything clicks, the team will say, “Wow, why didn’t we do this before?” n About the Author: Randy Carter is technologies specialist for Anderson & Vreeland, Inc.
