I have seen one and have been trained on one and in my opinion they are as good if not better than a Jv33.
However if you are looking at a latex machine then perhaps you would be better looking at the JV400SUV.
It has just won a major award, and I think its a very underrated machine
Everyone seems to be looking at latex as there is no smell, the SUV also has no bad smell and there is no laminating required and it has the best scratch resistance of any print I have ever seen.
There is also no outgassing required and Clours are vibrant ,We have 2 customers who are using them and both are very very happy
