I'm trying to get back into color printing and came across this Unicolor enlarger in a junk pile, the filter dials only go up to 17. Is that the actual value of the filter or this this a unique scale system to Unicolor? From what I remember the starting point was usually 20 or 40 on magenta and yellow 17 would seem pretty useless for most color printing.
For some reason the picture I put of the enlarger didn't upload in the original post. The dials only go from 0-17 with 4 spaces between each number and there doesn't seem to be a decimal as suggested in the answer bellow. Im use to seeing filter packs ranging from 0-170 or 0-200 does this enlarger only go up to 17 or is it scaled to something else and if so how does it translate to the usual values of 0-200 ect.? I wasn't able to find much info online about this enlarger
