I wonder if it is nescessary to insert a coated paper in the cuvette. If the
paper contributes to the UV-absorbance of the lightsensitive solution
used, then yes, otherwise I would believe that what you could do is to
put the cyanotype solution in the cuvette, and make a scan. That should
give you one or more absorbance peaks in the UV-region of the scan,
and they should correspond to the spectral sensitivity of cyanotype.

This could of course be done for any other alternative process as well. I
would actually believe that it has been done (Luis, Klaus ??????).

If you decide to pursue this subject, I would be interested in the results.
