Specifically it's a system whereby the last unit has a protective jacket mounted to the impression and a rotary die made of up perf / creases / knives does the job of a dedicated cut 'n crease machine. Here's the link The Link Anyone had any experience of these, we're thinking of utilising our 6 th unit for this purpose. Main questions are... How well does the system work? Are the cuts clean etc.? How tricky is mounting/dismounting the jackets? What are the drawbacks if any? Any info appreciated.
Since I have not seen anyone using it I can't opine; but the following videos on similar systems might give you some idea http://www.youtube.com/watch?v=iK3614Gf37U http://www.youtube.com/watch?v=7YE0xp8pgR0 http://www.youtube.com/watch?v=R6e6x1qdKHY
I would imagine if you're not using a uv press, that set-off would be a major problem. How could you possibly stop set off and marking of the sheet when it's covered in perfs and/or scores? Plus how fast could you run with cuts in the sheet? How could the sheet effectively slow down and knock up in the delivery?
We use a similar jacket system on one of our web presses by mounting the jacket onto a cylinder but the sheet passes between the jacket and a cylinder without packing on it. We do this UV and "normal" ink as well and have no problems with it, they last a long time as well.
I have used the rsp inline from Cito and it's great the sheets come out flat and you can still run at speed I spoke to k+b at ipex and agree that a flexible die is better than sticking it all on individually
I would press your salesman to take you to a customer that is running this system on their press so you can see it in action.
Ive used the Cito system for cutting and creasing on a B2 press at 6/7000 sph, although the sheets had been printed beforehand (dry) How well does the system work? Are the cuts clean etc.? YES How tricky is mounting/dismounting the jackets? EASY What are the drawbacks if any? You have ONE go at fixing the cutter plate so you MUST get it right. Watch you dont over tighten the carrier as you can split it. If youre die-cutting trial the niks
Richard, We just ordered the RSP SYSTEM from Carton Craft, we will be training in about two weeks, Ill let you know what the good and bad points are.
Kilrone, Can you give some feedback on your exp with the RSP system? How long do the dies last? Is this system best for 25-50-100,000 job specific sheet runs.... or can it take the longer runs of say 250-500,000? It seems like it may be best for those "job specific" die cuts as compared to say making 1,000,000 envelope or box dies cuts? Can you give any direction regarding the longevity of the system? How do you use the system and did it "work" for you? Thank you
Hi Richard/Kilrone, did anyone get an actual experience with the RSP system? Are you able to do an overprint varnish coating just before going to the RSP system? I'm thinking it might create scratches since the overprint varnish since it is still wet. 4C + varnish + RSP system.
