Lab+Channel+Missing

=Prints made through the Export plugin are dark and muddy and have a color cast=


 * Problem:** Prints made through the Export plugin are dark and muddy and have a color cast. Prints made from Photoshop through the regular 8 bit driver are fine.


 * Comment:** It appears that the prints are missing either the red/green (a*) channel or the yellow/blue (b*) channel of the L*a*b* color system.


 * Resolution:** None.


 * Workaround:** Convert image to printer profile in Photoshop before starting Export plugin and print with output profile set to "None (No Color Adjustment)".
