MIS Ultratone VM is a variable tone inkset.

There's a small PC application called Tiff-convert in the file
section that allows a Tiff conversion from Greyscale to RGB or
CMYK.
8>16,16>8 bits. LZW and ZIP compression possible in the same
action. Plain 0-100% Greyscale > 0-100% CMYK like the RGB file is
created and any setting per CMYK channel.
