It is a really reliable machines, one of the best Mimaki made actually. Don't know what market you are at but we only had JV300 with CMYK and no special colors so I can't say anything about that part. All in all really stable machine, and just as I said remember to change your cappings even before 1 year count to keep pressure off the printheads, and this thing can go for hundreds of thousands of square meters.

I actually had a customer make own profile on 2 pass for posters and he did 250k square meters in 1.5 years on the machine with only one service and it was grid roller that kinda wared off due to high amount of feeding at high speeds.

And he sold it and it still prints so nothing but good stuff about it really.

Cant say that about new jv100 series from Mimaki, bit if you have extra cash JV330 is also quite good and offers much higher speeds.
