I am trying to calibrate my Kodak 1400's linear density and 
neutrality. 

I have been offered a spreadsheet to allow me to convert the spectral 
data into density values, but I need to provide the wavelength range 
of the measuring device. (ie, Xrite covers 400nm to 700nm...whereas 
GreatMacbeth devices cover 380nm to 730nm)

I have searched and searched and I cannot find this information 
anywhere.

Does any one here know?

Also, does anyone here have any info/advice for using Printfix Pro to 
calibrate dye sub printers?

Any help would be greatly appreciated. 

Cheers
