Hi Lars Tore! Don't worry about the deltaE being high, printtarg just create a chart (I don't really know but I think the deltaE has something to do with the differences between patches on the chart, so big deltaE's would be a nice thing). I'm sure readings of the chart will be great using printread. Best regards Martin Weberg 2007/7/28, Lars Tore Gustavsen > > Hello again > I guess this is another dumb question.
