Alrighty
I personally love these types of huge, open ended threads because it allows me to write huge posts where I can just go on, in one long, incredibly unbroken sentence, moving from topic to topic.
Me
We have 2 printers in our shop right now. One is a VS-640 with CMYLLcLm+M+W and another is a Seiko based production printer.
Stereotypes
Roland
Mimaki
HP
Epson
Roland
Roland makes fine machines. The price is pretty decent and while they may not be the fastest printers in the world the quality is top notch and you can basically put the media on the take up system and leave it alone. You'll never get any banding (at least I never have) or head strikes if you aligned the media properly. My only problem with Roland machines is that they feel like toys. Don't get me wrong, what they do is superb. Quality is great, speed not so much but it's reliable and you can basically leave it to do it's thing all day long without giving it a second though, so speed isn't that important for me in that regard. We've never been delayed on the job cause our printer couldn't deliver fast enough. BUT they feel really fragile. Roland makes them really strong and they have a really nice, timeless design but they are also kinda plastickly and I personally wouldn't trust my VS with a 50m roll of banner.
So decent price, great quality, acceptable speed (there are fast Roland printers out there like the new Monster, so if that's important to you, worth a look). Feels a bit fragile though
Mimaki
I personally think that Mimaki is king of the hill as far as high quality solvent printers go. They're probably the most expensive of the bunch but they feel rock solid and have a very good quality. They're probably the best designed solvent printer out there, they're sturdy and did I mention most expensive ?
If money isn't too much of a concern I'd personally go with a Mimaki as it can match the Roland on print quality and pass it over on print speed and sturdiness
Epson
No way. Move right along, nothing to see here
HP - I'll discuss HP under Solvent vs Latex
Solvent VS Latex
Disclosure first, I've never owned a latex printer. I've talked to people that own them though and also know people that sold and maintained them.
Advantages of latex over solvent
- Maintenance
- Ink drying
- Odor
- Speed
- Environment
Disadvantages
Price, Price, Price
... and a few other things I probably can't remember on top of my mind.
I personally operate out of an market that's all about price. It doesn't really matter who your client is, if you want the work your prices have to math the market at least in some degree and the market is made up of one price cutter after another. What does that mean ?
Well it of course on what part of the business you're doing. If you're for example printing wall scapes and billboards, like we sometimes do, every cent you save on media, ink and other stuff is a cent you've earned. In this regard if you used latex in our market you couldn't hope to make a buck.
If you were to use latex in the high quality print market, you wouldn't be at an loss per say but would be making significantly less money than on an solvent printer.
Then comes the issue of the print heads. On average you can usually hope for latex to last some 3l before the heads go poof. If the printer has 6 heads, that's $600. On my VS-640 the DX head that's it in costs $2k. I've installed aftermarket inks on it a few months after I got it and since then we've replaced one head on it. That's been 2 years ago and we didn't pay for this head because our ink supplier concluded that the company that sells them the ink either sent them old ink or ink not perfectly suitable for this printer.
Anyways let's assume that we paid those $2k for the head. That's $2k for the head and maybe a couple hundred for servicing, so let's say $2.5k for 2 years of ownership and some 10,000 sqf printed (probably more, I don't know the exact number).
Our production printer had 6 heads but we threw out the lights cause we didn't need them so now it has 4. We bought it used at a bargain price and replaced 2 heads on it, that's around $1.5k and we've printer over 50k sqf on it using cheap mild solvent ink.
So what does it all come down to ? Convenience vs price
I am pretty sure that a latex based printer is better in a lot of stuff than solvent based ones. We had a mishap the other day with ink not being dry on something we printed and due to handling the print got damaged. This wouldn't have happened on a latex for sure.
Also when we had to replace our print head on the VS it was out of commission for 10 days cause we had to wait for a print head to arrive cause we couldn't get one locally. With the latex you would probably have a few heads lying around as spare parts.
For the average member on here this doesn't really matter cause the prices in the West are such that you probably don't have to worry about a $100 head every 3l of ink and the price of ink because the market is such that the cost of these is negligible.
That's perfectly fine, I'd probably get myself a latex ASAP if the market conditions allowed for it but there's no way a latex printer is cheaper to run than a solvent printer. The heads, the ink and probably the media is significantly more expensive on the latex side.
As far as maintenance goes, it really depends on the printer and just dumb luck I guess. The only real maintenance we had to do on our Roland was the head replacement. That's it. In 2 years that was the only instance and we don't even manually clean it. It's been months since we did it last, probably should do it soon though.
If you compare Eco Sol Max (Roland's ink) ink vs HP latex ink the latex probably wins out, but I don't know of anyone that runs Eco Sol Max in their Rolands after the warranty expires, I personally didn't even wait that long because the warranty we had was basically useless because the dealership was retarded but that's another story for another time.
Built in cutter vs separate machine
Our VS-640 has a cutter but personally I'd prefer a separate machine. If you have the space a separate cutter that can read the registration marks (this is pretty important) I'd go with that. The advantages are speed as you can print and cut at the same time instead of one process taking up the machine the entire time.
My Recommendation
If you don't really care about the price, either initial or later on the HP is probably a good choice.
If you want a reliable workhorse and your budget allows a Mimaki is the way to go. I'd get aftermarket inks on it as soon as it's viable though. I don't remember if Mimaki offers bulk inks, I know that Mutoh does but can't recall if Mimaki does the same thing.
If you can't afford a Mimaki but you want a high quality printer I'd personally go with Roland.
EDIT:
I just re-read the OP.
Transparency can be a nuisance but it's not that much of a problem. Ideally one wouldn't have to deal with it but we just flatten it and be on your way.
And regarding the print head price...no, the newer Roland heads cost $2k and the Mimaki ones should be in the same ballpark. But as said, this shouldn't be that much of an issue. It's not something you replace every day or year.
