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…

What is Closed-Loop Color Process Control for Digital Presses

Periodic monitoring of the aim characteristics (required colorant and overprint values) of a digital press is an important prerequisite for ensuring consistent color reproduction. The remainder of the necessary and sufficient operations for commendable color quality is the ability to correct colorant densities to meet aim values. Each of these two operations can be accomplished either manually or automatically via hardware and software. The former is the traditional process, which leaves lots of margin for…

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…
