A Development of In-line Density Measurement System— True Fit —

Abstract

TrueFit is the inline density measurement system used to enable the highest levels of print quality consistency for the TruePress series of digital offset presses. TrueFit is positioned above the paper delivery area of the TruePress and consists of a newly developed capture head and lamp unit. It reads the control strip on the printed sheets in real time as they are being delivered, enabling more efficient control of ink densities during printing. And because ink densities are being read and displayed on the operation panel in real time, constant ink density control can be achieved without needing to remove sheets for measurements. This streamlines and increases the efficiency of the operator’s work.
