Expose a set wedge onto TriX.
Develop in HC110 or your other developer of choice.
Create a characteristic curve.
Apply this curve to your digital captures.
For simulating the print: process a sheet of Brovira the way you like it to be. Obtain color and density measurements with a densitometer or photospectrometer (preferably the latter). Use these measurements to adjust your digital prints to look as close as possible to the Brovira original. Instead of the measurements, you can also match the prints visually by holding them side by side and making iterative adjustments to the digital print until you're happy.
