Violet chemistry free plates

Well-known member
I have a Heidelberg violet ctp and I want to know if someone has used the new chemistry free plates I been using lap v but it is not very easy to develop so I want to change. We almost don´t use this platesetter and use the lotem which is a lot more stable and 8 page.. the only thing is we have two plants and we have to send all the jobs to the lotem and its overloading it´s capacity. Azura works great on the Lotem.
 
Pablo:

It's great to hear that Azura works well for you on your Lotem.

WRT chem-free on your violet HDM device...
it looks like the chem-free violet plates announced
would work not on a 5 mW violet diode laser, but
perhaps a 30mW, and most probably the 60mW and
higher intensities. (This is not a blanket certification.)

As for Agfa, we are rolling-out our violet chem-free
plates first for the newspaper market, and have plans
to migrate this toward the commercial market shortly
thereafter.

Green:

I believe the current standard laser for Palladios now is 60 mW.

As I understand it, by the time the plate is released for commercial
market (rather than newspapers), there will be a 60 mW field service
upgrade available for those original 5mW configurations. Perhaps it is
already... check with your local Agfa service organization.
 
we are still waiting for fujis chem less plates, if i were you, i would in the meantime switch to photopolymer plates, the agfa lapv are terrible with there waste and mess produced, they should almost be outlawed, if you are running photopolymer you will be able to switch over to chemistry less plates using the same processor, you need one with a pre-heat, ring Fuji, they should even supply you the processor for free if you do enough volume.
 
Cosmo -

I understand your concerns about silver diffusion-transfer plates.
However, for many, they remain the best fit. It's a trade-off.

I believe in this case "Green" has a 1st generation violet laser,
which would not have enough power to expose neither Agfa's
or Fuji's photopolymer plates. 30 mW is border-line for some
engine architectures, 60 mW is most typically safe, but his
existing 5mW will only properly expose poducts like LAP-V.
