Some one asked about CTP system (Computer to Plate system):
What CTP system to Buy? We presently operate a Mitsubishi SDP ECO platemaker, playing around 2000-2500 plates monthly with punching offline. Its a polyester system and i am searching to maneuver up to and including metal system with inline punching.
We checked out the Heidleberg system, before we choose the ultimate order i needed to listen to anyones reccomendations. We are searching for a really high Ipi around the system ideally, and should have online punching. We operate a B3 set-track of about 99% of plate being to have an SRA3 sheet. All plates to operate on Shinohara 52 presses. Thanks ahead of time
And some people said about the CTP System as follows:
CTP System: The 1st Answer:
We make use of a Screen CTP and haven’t any problems. Check Fuji also its virtually exactly the same machine. They are able to arrange it having a punch around the CTP for your press.
We examined the Mitsubishi plates and could not encourage them to fit on press. Another price is what software to purchase to operate the CTP.
CTP System: The 2nd Answer:
How big plate are you currently making? Metal is not always the very best solution unless of course you are plating something wider than 36″ approximately or you are doing very lengthy runs. If you are searching to create the proceed to metal due to quality you need to consider a polyester plate maker by having an internal drum just like a DPX or perhaps a DPX4 with internal punching. Cost per plate is going to be under 1 / 2 of what metal is going to be – as well as time it requires to create 4 plates.
Polyester also offers the environment benefits connected by using it. The carbon launched just in manufacturing and moving metal plates before they get to your shop is one thing like 5 occasions those of polyester.
CTP System: The 3rd Answer:
Heidelberg Prosetter for that CTP and solids are 100%, and also the Glunz and Jensen Raptor Professional S for processing, maybe they’re better combinations available however it works best for me. Make use of chemistry for example developer and finisher however when we began out on a tight budget we found a great deal from Billy in Gloustershire who sells these gizmo’s.
CTP System: The 4th Answer:
Consistancy smart from plate to plate,you can’t beat Screen/Fuji systems,undoubtedly the very best plates available. We’ve the dad of these Platerite Ultima 24000S and it is superb, has online punching along with a good plate processor
CTP System: The 5th Answer:
Well, for which it’s worth, I’d go metal CTP is I possibly could. Why? Because I’ve had a couple of issues with poly plates. They are fine for brief run and place colour work, give excellent halftones and gradients (seriously, i changed an Agfa Accuset imagesetter for any DPX) but they’re a lot more vulnerable to stretching and damage. I additionally found I needed to run the press wetter compared to metal plates, which triggered knock-on issues with some covered papers adhering to blankets, setting-off etc. We went a GTOZ with poly plates also it would be a situation of having one colour to stretch to suit another by tightening home plate clamp for every job. The GTO was just four years old with sub-10mil around the clock and was well-maintained, so I am sure it had not been the press. The plates also had issues with conventional dampening when running fast. We wound up changing it with Varn models after trying a chiller/filter/recirculator with no success.
Still, in comparison to creating film by having an imagesetter, developing it, putting together it on foils for plating and lastly hands-developing the plates and hanging them to dry, it had been a lot more productive and the standard was comparable. We went 150dpi screens on every job. Might have gone greater but saw little point as nobody ever complained the our halftones were coarse.
If nearly all your printing is CMYK, then I’d say it is a no-brainer to choose metal CTP. If, as with my situation, it is a broad spectrum of labor with a myriad of place colours, a myriad of stocks and a myriad of run measures, then I’d suggest poly plates count a glance since they’re cheaper and almost always much faster. Basically perform a 100,000 run, I’ll make 3 plates before I start … in the end, they are smacked and press-ready so the moment I identify a rest-up, I alter the plate, operate a couple of sheets back right through to check position and adapt to match the prior plate (if needed) after which it’s all set to go again.
