Is the X-Rite DTP41b compatible with VersaWorks for profiling?
No, this is an outdated spectrometer that uses a USB connection which newer Versaworks versions do not recognize or lack driver support for. Recommend getting the current X-Rite i1 Pro.
In the past we have made a video using the X-Rite DTP41 (no b) which comes with a serial bus plug and is compatible still.
