To achive the perfect backlit i have built many custom profiles that dump on the the ink and are able to hit the appropriate DMAX (opaque black) in one run without sacrificing my color balance. It is a super big pain in the ass! I have built backlit profiles for HP9000, HP10000, Mutoh 1604...
The printers you mentioned were
Epson 11880 is a water based inkjet printer, not for outdoor use. (you may be thinking of Epson GS6000)

(MSRP just lowered so its not correct)
The Mutoh 1614 is a ecosol...
I would get in touch with the manufacturer, as they will probably be the only ones qualified to install and train you...if you decide to purchase. They will be candid an helpful. The machine in the crate was probably sitting around for a while, make sure to ask the manufacturer if that has any...
The encoder is located on top of the carriage rails. It is a mylar strip that runs along the top edge. It is generally clear with fine vertical lines on it. It is a part that should be kept as free of dust an debris as possible.
They are really great machines. Very good hexachrome inkset, exellent internal engineering on the printheads and the data system (supports gigabit ethernet and usb) smaller drop size than my aqueous printer....and makes a smoother print too. I have had a couple demos of this machine and I really...
Canned profiles work well for 90+% of the sign industry. If you get consistently repeatable quality color that is good. For those with challenging environments such as Las Vegas or Miami. Profiling or re-linearization may help.
The encoder is Printed mylar film strip. ProWrap is kind of right and kind of wrong. If you use the wrong chemical (such as solvent) you can wipe the fine tic marks right off. On the other hand who can afford to call a service tech out for every little issue? If you use distilled water and a...
I agree that Adobe RGB 1998 is best for print applications, but dont let that stop you from sending files that a designer built in sRGB to the RIP. If they designed in that space and you set up your Source profile in the RIP to sRGB then sRGB should work fine. Though I should say that I have...
Sending RGB to the RIP will maximize the amount of colors available to your printers full capability. If you convert before you send to the rip, its usually clipping everything down to much less than your printers full capability.
If you are critical enough to be hunting for better profiles a spectrophotometer like an x-rite I1 would pay for itself with the amount of media you probably throw away in a few months. Building your own profiles is the way for you to go.
If you are wondering how a particular file will look when output you can use the "proof color" feature in Photoshop to preview how your RGB file will print on your CMYK printer...on screen. All you have to do is pull the .icc file that you reference in your RIP from the "proof color" dialogue in...
These machines were designed to run run run. They dont like to sit for long periods. If you can load some scrim in the machine when you are not using it and make sure you perform daily maint. I'm sure you wont get flat spots in the pinch rollers (thats where this was directed?) If the machine...
