What is Closed-Loop Color Process Control for Offset, Flexo & Digital Presses and Why it’s Time to Retrofit

Periodic color monitoring and control of aim characteristics (color, density, TVI, G7, etc.) of an offset, flexo,or digital press is extremely important for ensuring accurate and consistent color reproduction throughout the press run. These operations can either be accomplished manually, semi-automatically or automatically via color measurement hardware and color control software. Manual color control is a primitive method of quality control that uses a “trial and error” process—and it’s costing printers worldwide millions of dollars…

Components of a Closed-Loop Color Control System and How They Work Their Magic

Adding a Closed-Loop Color Control System is often the best and most effective way to breath new life into an older offset press. The result is automation which decreases job make-ready times for instant time and material savings but it’s also the “great equalizer” too, which increases the color consistency across individual press runs, over time, and even across multiple presses or different shifts of press operators. However, to better understand how the closed-loop system…

Top 5 Reasons to Consider “Closed Loop” for Digital Presses

The traditional method of color calibration of a digital press is a manual operation, which falls into two logical categories. The first is a one-time task during the make-ready operation and the second is on going during the press run. With an automated process, color make-ready and run time press calibration fold into one continuous operation from press startup to print run completion. A high-speed color measurement instrument (in-line spectrophotometer) mounted on the press will…
