Roland SP-540V VersaCAMM - Use it for the labels for our line of OEM Compatible ink - the print and cut feature is superb for custom-cut labels and stickers. We first used it to perfect our OEM Compatible Inks through extensive and long-run testing. We run nothing but Eco-Sol Inks. Lost track of the years we have had it. Tangental Blades we replace a couple of times a year. Our Roland tech keeps it clean and it just keeps on keeping on! FlexiSign Pro works great on this equipment!
Roland SolJet Pro III - For Banners - Again, had it for years with no issues. Our Roland tech walks by it every day to work on Canons and HP's that need more maintenance. Like the VersaCAMM we initially bought the printer to perfect our OEM Compatible Inks. Likes FlexiSign - prints and cuts.
HP 360 Latex - Just bought it three months ago. Seems like HP went on to their next Latex so fast many new ones go for a song now. Again, initially bought to perfect our OEM Compatible Latex Ink cartridge. Now we are testing various types of rolled media - From Wrap Media to banners, it works flawlessly. Especially impressed with prints we are doing on various fabric media. The tensioner bars work with such precision even the stretchy media can be easily adjusted and run. FlexiSign is good here as well.
All three printers are good. The Eco-Sol printers by Roland do exactly what they are supposed to do. They provide prints on many uncoated media keeping the media cost /square foot down - way down. Operate at under 10 cents / square foot on the safe and not smelly eco sol with a good OEM Compatible. With the latex, we have the color gamut that would make Michael Angelo cry with approval and we have the cost / square foot down to 12 cents / square foot so the latex ink cartridges for the HP 260 and 360 series are being met with uniform acceptance by our dealers as well.
Please don't contact me about the OEM Compatible Inks - I'm not paying to advertise here (yet).
It all really breaks down to what you are planning on printing and how much. If all you print is outdoor banners, occasional perforated window film install, POS items for a beer, food, and wine distributors, etc, etc get an eco-sol printer. If you are doing vehicle wraps, fine art prints, or just need a printer that will not take forever to get the media dry enough to deliver you may be looking at Latex (or with high volume UV Curable). Make sure you have techs close to you (or train yourself for minor installs or printhead recovery techniques) for your chosen equipment (when you pay for their travel time it is a killer).
Oh, the HP's have had higher maintenance by far over the Roland. Our techs work on Mimaki and, depending on the printer, Rolands with similar features usually require less maintenance than Mimaki.
