        The images can be lightened significantly using the property -Dorg.icepdf.core.cmyk.image.black=2000 however its isn't an exact match to the background fill colour. The underlying issue is related to http://jira.icesoft.org/browse/PDF-765. We can use the Adobe ICC colour profile to fix this issue but we need a way to speed up the colour lookup.

        The line width issue on the first page is still an issue but progress has been made on the CMYK colour issue. the images on the second page look a lot better on version 5.0.7

        Marking as fixed as images and fill colours are a much closer match.
