Color communication, (Spectral Data, CIELAB, CIELch, Chroma, Hue, Saturation) can be difficult especially in the press room where there are no press adjustments for any of these items.
SpotOn! Flexo makes this communication easy. With each measurement SOF provides the press operators a series of easy to understand icons.
|Acceptable Color Match - (based on dE to reference)|
|Acceptable Color Match can be achieved by Increasing or Decreasing solid ink density (SID)|
|Failed Color Match - (requires new ink formulation.)|
SpotOn! Flexo uses a Predictive Analysis Algorithm to provide press operators the optimal ink density to run a color to achieve the lowest Delta E (dE00) to the desired reference color. This new pressroom metric is called running to Delta E rather than running to solid ink density.
Solid ink density (SID) has been in place in the pressroom for years and years and is a great tool to monitor a color once the correct color has been achieved. SID is a measurement of Lightness/Darkness and has no color reference. Hence you can have the same SID for a Magenta and a Cyan ink which are drastically different colors. This was the case in the recent FTA FIRST-in-Motion project.
The new pressroom metric is Running to Delta E. Delta E (dE) is a colormetric calculation that compares two selected colors and provides a number representing the color differences. For example, a dE00 of 2.0 is considered a good color match and a dE00 of 6.0 is an unacceptable color match.
SpotOn! Flexo provides the press operator the current dE and also the optimal dE based on possible ink density changes.
