Thinking about a Screen PT-R4100

[Happyprinter]

After several months of searching we are thinking about purchasing a Screen PT-R4100 unit. Anyone have any comments or experience operating this unit? We are going to use a Harlequin 8.0 RIP. Like the idea of being able to use ChemFree plates. Any comments will be greatly appreciated!

Is it in the good condition? How much are you paying for it? Go for it with out hesitation my friend.

ok, it's a good machine, but the 4100 has 16 diodes rather than 32 like the 4000 of that age.
So, if you're doing chemical free, it depends which plate you're using (and also the size)
So of the Agfa plate need a lot of power, and the Screen machines have to slow down the drum to almost half speed to expose intensely enough.
So, You start at a point where the 16 diodes are already half speed of the 32 diode machines, then you slow the drum almost half speed again... When people do this with an 8 page plate 8100, it's a long time per plate (8 minutes or so?)
On the other hand, it is what it is, and if your coming from a film to conventional plate set up, you might look at it and say "Wow! I'm getting a plate out in 8 minutes! That's great!"
Also, if you're using a lower power chemical free, like a fuji pro T plate, it's not so bad, and also , if you're running very small plates, Ryobi sized, etc, you'll be fine too.
Otherwise, great machine.
