I'd like to hear from anyone having experience with violet CtP in a newspaper environment. Any issues? What about processless violet? FM screeing capability?
We started using violet Agfa LAPV silver plates in 2004. We were able to get our plate curves in place in a very short amount of time. We did have a few issues with blinding on press when we first starting using violet plates, but it turned out to be a bad batch of chemistry from Agfa, who quickly replaced the chemistry for us. After that, we never had any problems on press. The quality was very good, and the press operators loved the plates. The biggest downside is the messy job of keeping the plate processor clean. It was cleaned every 4 weeks, and took several hours, and we always ended as purple prepress people. A few years ago it got very difficult to get the LAPV plates from our supplier. We had to make a choice to either use a different vendor, or change plates. We went with our same vendor, and switched to Kodak Thermal Direct plates, which does not require a processor. It took quite a while to get our plate curves set the way that we wanted, since we cant read the plates with our densitometer. However once we got the plate curves in place, the plates printed much better than the silver plates. We have been very happy with the switch, and are no longer purple prepress people.No one?
What about violet CtP experience in general. Issues? What to watch for etc.
We have been loyal to our current vendor for over 25 years. This goes for graphic supplies, and equipment. We also feel that thermal is much cleaner, and less hostile on the environment, than violet silver based plates and chemistry. The vendor for the Agfa plates is not locally based, which makes it difficult to do business, especially if we need a product the same day. Once we went to thermal, we found that we have a much wider printing latitude on press. In the same step, we also installed a new proofing system, and had proofs profiled to the press with the thermal plates. The matching of the proofs to the final printed product is much closer than we were before. So overall, the outcome of the change of plates and proofing in our opinion is superior.@sev
So you switched from violet to thermal? Why didn't you stay with violet and simply change plate vendor?
That's what you have...but what is your experience?We are a mainly Newspaper Printer and have a commercial Customers and we have a violet ECRM Mako with Proteck 70 inline Processor. We use Southern Litho Violets plates. We did do a colortone press match to the workflow. We use Presteligence Imposition Workflow. It also uses InkMiser plugin.
Oh. The CTP device is excellent and does a good job, no trouble with it. CTP device repeatability is excellent. The processor is another story, had trouble with it. Sensors that was supposed to signal low developer level was defective right from the beginning. Thus when a fitting leaked, it burned up all the plastic guides and had to be redone and cleaned at every joint.That's what you have...but what is your experience?
Although the autonomous car is not quite ready, a lights out print operation is something you can do right now if you have a comprehensive Print MIS (Management Information System). The advantages can put money on your bottom line. So what’s your next step? Link to Article
