I have setup a new curve for my process, but How do i set up a curve to a Spot colour? I'm using SymphonyCalibrator. When i send a job to RIP, it fails on the Spot colour. i would then have to assign a black curve and retry the job again. SymphonyCalibrator does offer additional curves, but are named LightMagenta, LightCyan, MixMagenta and MixCyan
