Screen PTR-4100

Well, we finally got a Platesetter from a shop that sold off its business.
Got the 4100 for about $15,000 so we jumped on it. Now I have to figure out how to get it up and running.
We are trying Fuji's Eccomaxx-T plates to start.


Anybody familiar with such a setup? I'm sure to have some questions!

Same model we have. Was running Kodak when I started... now we're on [Agfa] Azura TS.

The shop we got the 4100 from was also running Azura.


What was the deciding factor for the switch?
And, do you and the pressmen like it okay?


I'm not really locked into a manufacturer at this point, but we have a good relationship with the Fuji sales guy and wanted to give him first shot.
Also, I'm really wanting to be able to use our existing plate processor to develop the plates. It has a gum unit after the wash. If anybody has tried this, I'd be interested what chems you used, our press solution is too weak at the prescribed for press use. We are thinking of trying a very strong solution to se if that work.

I/We have found Kodak plates to be horribly inconsistent, even thermal (but especially violet/poly). Sceening is just miserable. Plate wash would sometimes even remove image from the plate too. Azura plates were cheaper, consistent as can be and have a long run life. We made a deal with Pittman (now Agfa) to buy plates from them for two years, and they gave us the processor for free, with a 1-year service contract (which we never used).


And, do you and the pressmen like it okay?
Both the pressman and I love Azura. They never had the consistency on rerun orders like they do now (but some of that may have been the previous prepress guy). Screening on a clean plate vs. a plate near the time the processor needs cleaning are pretty much identical. My dot reader has a + or - of 2 percent, and I am reading plates that vary by less than .5 percent. Kodak would be all over the place, but Agfa is steady.

The Azura TS processor only has a gum solution. It's basically a chemistry free "processless" plate. The ph factor is neutral so any residue can safely be poured down a drain without a ProCam solution additive, and I don't think you even have to notify your local Hazmat of the Azura gum solution. Cleaning the processor (including rollers, scrub brushes, etc.) take 1 man about 2 hours or so give or take... and in between cleanings, just run rinse water and change the gum.

Going to have to disagree with you on the Kodaks, we run both thermal kodaks and agfa and we have issues with the agfas (plate wear, blinding, sharpening during make ready, Kodaks on the other hand don't seem to have those issues.

and a half percent range? Brother I want what you are smoking? Hell a freaking dot reader alone can have a variance of a percent depending how the patch is read etc..or how many times you read it.

I have to agree with this and Kodak plates. There was a bad batch of Sword plates released into the wild but they cleared that up pretty quickly and even gave plate rebates over that fiasco. The Trillian plates are great though. Truth be told, any of the major plate suppliers all have good plates. They can't stay in business if they are selling junk.

I firmly believe a lot of it has to do with maintenance, and how well you keep your processor and optics clean.


As for the percentage difference, I usually read it three or four times and take an average. I made a screen pattern in 5% variances to run without any curves and not linear to get it to a linear starting point. I claan and re-read my test plate monthly. It stays right within range always.

I was caught up in that batch of bad sword plates and their handling of it left a bad taste in my mouth. That being said if they made a plate that is a good fit for our shop I would give it a try.

Thanks for the quick replies, as always with this crew!


I just output our first plate for the Komori, and will be using it for a job later today.
Just one color-K so I have some grace on this.


A very worrying thing for me is that the Fuji plates barely have any contrast after developing, so to get a good read wasn't possible with out plate reader.
Our service tech is sending the plates to some company that writes the software for his reader, but in the mean time I don't have a calibrated plate!


We are just running one color stuff with no to little screening, so I can get away with it for now. Just to get this up and running.
Anybody had issues with getting the plate to read, oh, and I have a iCPlate II reader.

Hell, even the gum will add a half a percent. When we had our G7 fingerprint done, the tech would make me clean the gum off before reading and it was adding 0.6% to the reading off the Ultra-Dottie.

Okay, we're up and running.
I'm getting a line across the plate right where the page edge is in the file.
But there is nothing in the files to print. All files have done this, PDF or Illy, doesn't matter the source.
Any ideas what may be causing this? It is the tail end of the image, or the side furthest away from the punch.
