Description
In version 4.1.2 we introduced an new algorithm to convert CMYK to RGB for various image types. In general the algorithm did a better job then the previous version but as a customer has pointed out that most converted images render a darker then the baseline.

- Subversion
Tweaked the black channel in the cmyk to rgb colour conversion algorithm. The new smaller fraction value of black lightens up most images and the makes the image much closer representation of the baseline image. The logic is a little fuzzy and subjective but offers an improvement over the original algorithm.
