I use the Epson PRO 3880 have never had any problems with the heads or nozzles clogging. Any of our epson printers that use the K3 inks has never had a nozzle or clogging issue.
You can use any of the colors to make the plates some may be hard to see but they all work. It is the resins and not the pigment that is the functioning portion.
To do 2 sides of the plate your print let it set for about 5 minutes then run it through the epson again. If you are making multiple plates do all one side then by the time they are done the first one will be dry enough to run through the second time.
If you already have a laminator just get some teflon sheets about 5 mil thick put your plates between the teflon sheets and run them through. You can reuse the teflon sheets hundreds of times.
I bought a refurbished Epson 3880. The rip software was $700.00 (you supply your own computer nothing fancy just make sure it has 4 gig of ram and windows xp or higher system for $650.00 or less)
This is the laminator
Amazon.com: Sky 480R6 Photo Pouch Laminator 18.9" Laminating Machine 6 Rollers: Office Products about $800.00
The Rip installation was a breeze. The rip manufacturer has a live hookup to assist you in setting up.
My initial pressroom investment included, 100 plates, 1 gallon of Universal fountain solution, 5# Habitat Dense black ink , 2.5 gallon of No Odor wash, 1# transwhite ink for the old inks, total $392.00.
On press I pre-wet the plate with a weber wipe wetted with mixed fountain solution. Usually the second sheet out is good.
The old inks I have are from various suppliers and up to 20 years old. Every time I want to use the old inks I just added 1 oz of the transwhite per pound and they have worked. One can was a special purple from 1991 it had about a .250 skin on top. I took off the skin added the transwhite and it worked just like a new can. I can now use up all of that old ink on the ABDick.
The ink,fountain solution and no odor wash is Made in the USA.
In my opinion this system of the plastic plates with the BestChem Universal poly fountain, Habitat ink and the No odor wash is a no brainer. Easy to use very good quality and the crowning point low cost to operate for both plate making and press operation along with no click charges.
