Still working on it - Epson 265 printer - and tend to have Epson paper. I used the tools suggested last night , and need to check the results as although "better", this could also be due to brightening the image prior to printing. I intend to concentrate on this over the next few days to get it right. I will resort to a callibration tool by Saturday, if I can't get it as I am using acres of ink!
Thanks all for your help - will let you know
Nellie
