Is it possible to use ColorMunki to measure Dmax of a print? ColorMunki can read patch values in LAB. Is there any way to convert that to density?
By using X-Rite ColorPicker,
if you are able to extract the reflectance data from a CxF exported file,
you can put them in a spreadsheet and get a very good visual density value estimation for the blacks by doing a simple calculation as follows:
=ABS(LOG(AVERAGE(A1:AJ1),10))
(assuming the reflectance data is a row from A1 to AJ1, as could be for a 380-730nm data set using 10nm steps).
You will see that, if the tone is reasonably neutral, the results will be very close to the ones you can get using the LindBloom "SpectralCalculator10nm.xls" spreadsheet.
If you get the reflectance data from Argyll chartread,
be sure to scale the values down by dividing it by 100 before doing the same above math
and pay attention to avoid the use of -H (hires) option.
I hope this could be useful.
Ciao.
