Vuescan supports the 10000XL and much more scanner models. Works in 3 OS
environments. It allows a RAW DNG export (disguised Tiff) without any
influence on the image. Could be a good start for this instead of using the
Epson software. Add a whiter patch than the original to the scan, for
example a stack of Teflon tape. Any unknown OBA content in the original may
still bring its white above that level though, depending on the scanner's
light source. RAW profile based on Colorchecker or profiling after the RAW
stage
Met vriendelijke groet, Ernst
