we have gone rounds with company we bought it from, he is the one that thinks its the RIP software, we have put a whole crazy humidity system in the shop of course we've got like zero help from Mutoh. I'm in the states so i will look into 30 day trial. I've ran a few different printers over the years never had these issues especially with a new "top of the line, award winning" printer.In my experience, while a RIP can be the cause of banding, it's not usually the first thing I would look at. More often it's machine related or environmental -usually low humidity causing static related issues. I think Onyx does a great job of color management though and you won't be disappointed with that, if you learn to use it correctly. Over here (in the USA) you can usually get a 30 day trial of the RIP to try it out, but to be fair to the software, you should have someone knowledgeable with the software to help you get the most out of it.
Good Luck
That is what the tech is saying, I guess someone else was having the same issue and he switch the rip and it fixed the problem. I personally know of another shop that has the same printer bought it maybe like a month or two before us that is having the same issues. Yes we have also reached out directly to Mutoh and they have been working on a "solution" since Decemberbanding issues would not be related to the printer, however, banding issues will affect your color. You may want to make sure your printer does not need a laptop or damper replaced before switching rips. Did your tech say it could be the rip? Did you reach out to Mutton directly? Seems odd someone would say this was a rip issue.
This machine has been Odd since the day we got it. we have to use our 12 year old Roland sometimes cause the way the Mutoh prints.still seems odd but download the 30 day trial from their website and try before you buy
