Has anyone notice if you change the height of the colorhead then you have to change the YMC settings to compensate for a change in the color temperature of the light source? The changes are not large, but they are needed.
To be honest, no. I have not noticed a change in color when adjusting head position. I do notice that an increase in exposure time is needed to maintain the density of the print as the head is raised. The first rule I learned 20 years ago working in a custom lab was to nail the density first, then adjust for color.
