Published on October 26, 2010
Cary Sherburne: Hi, I'm Cary Sherburne, Senior Editor at WhatTheyThink.com and I'm here with John Kaufman who's Product Marketing Manager for Fuji Film Graphics. Welcome John.
John Kaufman: Thank you.
Cary Sherburne: Now we had the opportunity recently at Graph Expo to see the J Press in action -- the J Press 720 in action and it's really quite a unique product. Maybe you could take us through sort of verbally, you know, how has it constructed and what happens with -- how does the paper go through? You know, what's the technical process we're dealing with here?
John Kaufman: Well, what's interesting about the product is, is that is uses typical carriage -- undercarriage that you see with an offset press -- typical feed and delivery. What we do is we take the paper into the press and we precoat and we do it in a aquos type coating. We flood coat the entire sheet. What that allows us to do though is control the dots so that the dot does not dive into the substraight, okay? So in allowing us to control that dot then we can get consistent, accurate color throughout the entire pressrun. And that's what really makes us unique when you look at the, you know, verse drop-per-drop demand type technology with that precoating.
Cary Sherburne: And so the precoating also allows people to use any standard coated offset stock then?
John Kaufman: Correct, yes. That's the key. Any coated offset stock that they currently have in their shop. Also allows them the leverage to buy traditional sheets that are currently from any vendor, get the best pricing and so forth.
Cary Sherburne: And so the sheet gets flood coated and it goes into the imaging stage?
John Kaufman: It goes into the imaging stage where we have Fuji Film dynamics heads and --
Cary Sherburne: Seventeen of them, right --
John Kaufman: Seventeen.
Cary Sherburne: -- on each bar?
John Kaufman: Correct, absolutely. And there is over 35,000 independent nozzles within that printer bar and we can put variable droplets down and again it gives us the 1,200 BPI and over 2,700 B2 or 4-up sheets per hour.
Cary Sherburne: And that's four bars, right? One per CMYK?
John Kaufman: Correct. CMYK, absolutely.
Cary Sherburne: And then after it's imaged?
John Kaufman: Yeah it goes into a drying process and we are currently using halogen type lamps around the cylinders and then it goes out the exit. We have what we call an ILS censor that scans actually each head. So you're actually putting out 35,000 independent lines. We're measuring all those lines and we have a closed loop system for color correction with -- in regards to that so we're constantly managing the color. We can actually hold something that's close to a delta E of three.
Cary Sherburne: And there's a fusing process, I understand.
John Kaufman: Yes the -- it actually goes through the I -- through the dryers and then we go through a fixing process where it's just a heated roller and a little bit of pressure.
Cary Sherburne: And then flip it over, run it through the second side.
John Kaufman: Yep. Yeah. It's completely dry so the customer if they're only doing single-sided work they can actually take the job and run it into any type of finishing that they currently have or if it's work in turn they can send it back through the press.
Cary Sherburne: That's great and so this is just -- you're just going to begin installing them. I understand there are a couple installed in Japan but in North America --
John Kaufman: Yeah, we're looking at delivery of these products come this spring of 2011 so we're taking orders right now while here at Graph Exp.
Cary Sherburne: Where do I sign?
John Kaufman: Come down the booth and we'll get you signed up.
Cary Sherburne: Alright.
John Kaufman: And ready to go.
Cary Sherburne: Thank you.
John Kaufman: Great. Thank you.
