    Chinese thermal CTP plates?

    I want to ask some questions to anyone using chinese CTP plates.
    1) What brand of plate and what chemistry?
    2) with what CTP manufacturer model it works
    3) how frequently you do linearizations and focus calibrations?
    4) resistance to UV inks?

    I know it is a lot cheaper if you look just at plate price. But what about long term view?

    Cheers

    I have been doing test for chinese plates but it was not very successful. It was really hard to find perfect calibration for these plates. Each piece of plate was other. But black and white print - OK. I don't recommend for high quality print at all

    I use plates of brand Huaguang for the role and sheet press.
    Developer Fuji hd-p8. Mark of the proattendance processor: G&J PT-135.
    Linearization I do for each new party.
    In the last time quality of plates, has in my opinion improved.

    1) AGFA Energy Elite. Аmount per month 5000-6000 plates.
    2) Suprasetter 74
    3) i make 1 linearization per 3 month. From new party to old party is no great difference. max delta 0,5% in 70% field
    4) UV inks not use. But I think possible use UV for this double-layer plates.

    1) Used many different brands. In parallel, 3-4. Аmount per month 4000-6000 plates.
    2) Screen 4300s. ABS 175 lpi. Sublima 200 lpi.
    3) Never did. No time. It makes no sense.
    4) UV inks not use.
    In recent years the quality of some brands have improved, the majority has not changed, the minority initially unsuitable.

    we were using some chinese plates, huahuang and xingraphics, but we were also using kodak so it was difficult to us to find a balance in calibration, the achieve best perfomance is to work with the same chemical brands as the plates. but we werent going to give up using kodaks because the durability is higher although the price in chinese plates are more lower.

    Key is to source the correct supplier

    It is critical to do your homework and understand the makeup of your product.
    Then investigate your supplier if they are comply with your needs

    you know, the problem is that the Chinese plates we use do not even have proper labels. Because we are close to China, they are imported in generic yellow cardboard boxes that are labelled "thermal plates, size X x Y". And then we have to refer to them as "you know, the ones that are lighter blue" or "the ones in the dark-yellow box". Otherwise, our experience in very positive on Kodak Trendsetter CTPs. I described it in one of my earlier posts, I guess you can find it by username.

    My own experience between kodak plates and chinese are the residues. The chinese´s emulsion obstruct the ducts and bombs of the developer machine. I must clean every week and change the filthy filter. I make 1400-1800 plates per week. We have bandings problems too. Before that with kodak plates and developer regenerator we have to clean once per month. I dont know the actual brand because the boxes only have a distribuitor sticker. But we´ve tested two brands with the same problems.

    We did also tests on chinese plates and had the same results. Variations between plates were to big to print highest quality.
