    We have a Kodak thermal CTP since 2008. And maintenance is easy. Just keep cleaning. These devices are like a toaster. We burn about 100 plates a day and never had problems.

    I'm sorry, someone used a combined solution for flexo and offset plates?

    I like the comparation,

    "These devices are like a toaster."
    A friend recently compared our service as "tire repairman" due to low prices charged...

    I believe that thermal will rein. No need for a darkroom, seems to work better without chemistry.

    things are changing...

    5 years ago Lüscher was trying to push the UV (conventional plate) technology but didn't have the success it needed to thrive. The machine's price was almost double of a thermal Kodak or Agfa, the brand was relatively unknown, and the Euro exchange rate was hiking. Also, the plates are not just any conventional plate, they need to be quite sensitive and those were more expensive (still much less than thermal, but more than your standard conventional). And to make things worse, BasysPrint had made such a bad reputation for conventional plate imaging, because their first generation machines were so unreliable and had so much quality issues.
    But the chinese don't care about such things, so Cron went ahead developing their UV machine; now it seems to be relatively stable, a lot of chinese manufacturers for the high sensitivity conventional plates, prices exactly half of thermal plates. Machine cost, about 10-20% more than thermal chinese, which is to say about the same or less than western thermal machine.

    Right now I would either buy this one, if my volume is high and cost is the most important thing, or buy a thermal with Azura plates, if I want to feel ecological and don't care paying twice as much for the plates, but rather prefer a clean operation without chemistry and with little process variation. But using standard thermal or violet makes no sense, only 10% less than Azura, if I really want to save I go UV and save 50%. UV (conventional) doesn't need a darkroom, by the way.

    Changes

    I have been working on Lusher Xpose 130 model (made in 2007, originaly with thermal diods, that have been replaced with UV diods in 2009.) Machine was capabile of exposing any kind of conventional plate (China - Konita, Spain - Ipagsa, Slovenia - Cinkarna). And what is most important it did not needed any kind of service, only regular maintenance. As for the BasysPrint the new models are realiable and quick, but they are not on the same level of quality compare with Lushere.

    I think Agfa has some good violet plate technology in there chemistry free violet plates and the equipment is cheaper and faster.

    Hello,

    I think that with UV you like to say Photopolimer Violet plates, not confuse with silver-halide plates, violet light aswell.
    My experience with Fujifilm PRO-V is around 10 weeks without change developer.
    I can add good stability and nice jobs with stocastic screen.

    I believe that the UV like in the imagesetter will prevail. Red technology LED will happen to background.

    Thermal CTP plates are levelling up with Violet plates in terms of price. For quality and special screening such as hybrid and FM, I will vote for Thermal CTP. If I am tight on budget and just want to eliminate some prepress processes like stripping, I will go for violet CTP.

    Hello,

    I´m working and I´m technician for this machines.

    I think the best are the Thermal CTP machines.
    YOu don´t have so many problems.
    The best I think is the Trendsetter from KodaK or Topsetter, PLateRite, Luxel

    I use AGFA Palladio II with violet plates.

    I noticed some inaccuracies in the plates. Analizing the entire plate area, there is a fair variability of the screens percentages, especially at low values (2-5%).

    Often I notice also a variability from plate to plate: it is difficult to have a stable exposure level.

    Are the thermal CTP more accurate?

    thx
