Monochrome+Tinting

=How much difference is there quantitatively between the Cool and Warm settings in Monchrome mode?=

To assess the difference quantitatively, step wedges were printed on Epson Premium Glossy Photo Paper using perceptual intent. Step wedges were printed for Cool Black (X of -36) and Warm Black (X of 36), and measured with an Eye-One spectrophotometer. The results are plotted against %K for L* a* and b* in separate graphs. White point for the paper was 95.0, -0.3, -4.0. The a* channel was so close that any variation between the two settings is most likely due to measurement error. Note that the highlights are on the left, deep shadows on the right in these graphs. Charts follow:
