    I think Thermal is very accurate. When you do a good linearization you have no problems especially in the lower from 1-5%.

    im tec. eng. for "fuji + ffei violet box" and "screen + topsetter from heidelberg" thermal
    so violet vs thermal is not good debat
    violet is for speed less complex for repair and maintenance less expensive for parts
    thermal is for hight resolution and hight ruling and less problem for safe light

    From what I understand

    Thermal is the best (however lasers wear out) plates in NZ are also the cheapest but not once you add the cost of a new laser.

    Violet requires , YELLOW Light safe room, arent quite as hard in terms of number of impressions. But easier to maintain, and some have less water requirments in the wash.

    VR Platesetters are almost gone, last one i used was a tigercat (ecrm) plates image and lasting arent as good.

    After many years on the field as an application engineer, I would definitely say Thermal.

    Some question i want to ask:
    1. Plate price, which is cheaper? violet or thermal?
    2. what is easy to maintain?
    3. how long a violet and thermal laser last?

    Cool

    Fact about UV, Violet. Thermal

    Violet is weekest technology,
    1. Low quality reproduction, Sensitive for manipulation and storage
    2. Low cost device
    3. expensive plates
    4. for low budget company with low consumption. For starter company.
    5. Buy now and sorry later.

    Thermal
    1.Excelent reproduction
    2. Low cost device
    3. expensive plates
    4. For company with low and medium production, and high quality demands.
    5. Never sorry except price of plates

    UV Technology
    1. Equal or better reproduction than thermal ( yes, yes, is true) (on Luescher not on Basys)
    2. Expensive device
    3. Low cost of plates, 2x less than thermal. Almost 8 years "Analyst" speak about trend that thermal price soon reach price of conventional plates. As i remember nothing happen, except lower price of conventional (UV) plates
    4. for medium and high production and high quality demands
    5. Buy now or you'll be sorry later (except if you have small ammount of plates). Best way is to calculate you production first.

    (I have nothing about personal opinnion)

    Luscher is referent CTP in Fogra. It's possible to order 16 000 dpi device for special needs.
    Image thermal vs uv, X 500 enlargement atached (2400x2400 dpi both device)
    (note! basys is 1400x1400!)
    on Basys head is around 20 000 US$
    on Luscher head is not consumable :)

    Fact
    Luescher has announced the sale of a Simultan XPose! 130 to the Russian banknote printer Goznak. Goznak is one of the oldest printing companies in Russia who recently celebrated its 185th birthday. It is based in St Petersburg where Tzar Alexander established the company to produce state papers and later on banknotes.

    One of the main reasons for selecting the Simultan XPose! 130 was its ultra high resolution and, in view of the continued requirement to improve the security of banknotes, the resolution levels were a strong contributor in the choice.

    IMO. Thermal is better if you are into commercial printing. And yes, thermal is more accurate since it uses more power to image the plates. Thus making it more stable and repeatable.

    If you like to says that plates with hi power requirement are better you are wrong. They are slower. They need. Hi laser diod or slower drum speed. It means slow throughput.

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 use thermal CTP from Screen but Lusher Xpose is good machine.

    Thermal is better. If you use Voilet laser, you should better go with autoloader($$$),,because voilet plate can only be loaded manually in yellow light room.
