Hmm… well that’s not right! Let’s see if we can sort this out.
The raw profiles are only applied on RAW files (so either camera scans or RAW DNGs from Silverfast or Vuescan.) Tiff files from Epson scan are already “fully baked,” so the raw profiles are not applicable to them.
The step to “white balance” off the border is really only applicable to RAW files as well… Lightroom’s white balance works differently internally on RAW vs Non-RAW files.
Did you follow the steps in this guide on using EpsonScan with Negative Lab Pro? The settings you use in EpsonScan are important to getting a good, final result.
Also, while the initial conversion should absolutely not have this much color cast, you should be able to manually remove the color cast using the color sliders in Negative Lab Pro. You just need to add red to offset the cyan.
