Epson R300 - B+W photos have a purplish tint/cast not true B+
I have an Epson Photo R300 and use PS version 6.0 or PSP version 11.
When I desaturate a colour photo and then print it or when I print a scanned B+W photo there is a purplish tint/cast to the photo rather than true B+W. I have also changed to greyscale rather than desaturate but still get the same tint rather than true greys or blacks
