Horrible banding with tif scans

Hey all,

I’m trying to get usable scans out of silverfast tifs so I can utilize iSRD and finding it basically impossible! I’m getting horrible banding when using 48->24bit tif option. They look like what would happen if you saved a normal image as a 16 color gif, with all the colors sort of arranging themselves in blocks. Is anyone else seeing this, and if so, can you suggest a fix? I’ve tried random settings here and there, but Silverfast’s UI is horrific and nothing has helped so far…

I’m using a Plustek 8200i if that helps.

Can you post an example?
