Thank you Terry for that reply.
My Vuescan settings are as follows.
Scanner - Calibrate
Input - Bits per pixel - 48 bit RGB
Input - Scan resolution - 300dpi
Color - Color balance - None
Color - Scanner color space - Built-in
Color - Output color space - sRGB
Output - Printed size - Scan size
Output - Only raw file ticked
Output - Raw file type - 48 bit RGB
Output - raw output with - Scan
Those are the only ones I think are relevant to this project unless you know differently
This is what I got with these settings.
I assume that before I profile my printer it is essential to get the scanner profile correct?
Many thanks again.
Regards
John
