Supported Processes
We tested our tool with scans of following color processes. Adding new processes is relatively easy provided that scans are available.
These processes are easiest to work with. Because manual screen alignment was necessary, these processes have relatively large color patches (100um and bigger) which makes requirements for resolution of the scan pretty low. The fact that taking screens had match precisely the viewing screen forced manufacturers for high precision while producing these. We also believe that dyes used to produce the screens were consistent between individual batches.
We tested negatives, positives scanned in RGB and positives scanned in infrared.

Digital color rendering based on Finlay color negative.
Making screen integral part of the emulsion allowed manufacturers to use more fine color patterns.
We tested reversal film digitized using Nikon Coolscan 9000ED at 4000DPI both in RGB and infrared.
Random screens are hardest to analyze and so far we only achieved partial success with these.
We tested positives scanned using Eversmart Select at 5480DPI.
