thank you for the suggestion. However as I already use the the luminance setting of 80cd I thought I should look at my viewing/print to screen environment. I reviewed the external factors at the viewing area and changed things around a little. Especially with respect to outside lighting coming in.
The image on the CS240 under the Grafilite viewing area now looks in my eyes to be very similar and acceptable.
As I print reproductions of original paintings oil, pastels, water colours, drawings collages etc etc. for a number of artists. It is important that my colors etc. are as accurate as technically possible.
After this the real test is comparing the original art work to print. I always tell artists that if I get 95% accuracy we are doing very well.
The best judge is my other half who is working artist and have a very good eye for colours. ( the artists I work with say if Marilyn likes the colours then go for it)
thanks for the help.
