Question for S Roque users re: pre-reg system

[Shanarchy]

What are the thoughts on the PRU registration system?

I have standard U clamps, not the pin heads.

I have a tri-loc system now, and have ordered a S Roque registration pallet.

Opinions on using tri-loc vs their pru system?

As long as the reg pallet hits in the exact same places that the tri-loc jig does you're good.
Me I'd sell the tri-loc and order the pru.

I should know this after reading so much lit on these presses last year but would the PRU work with regular ol' M3 frames without any tabs, pins, etc?

We just got a reg pallet, our YOU had U clamps and our ECO had pin system, so one had to change. Long story short, with the reg pallet we are switching the ECO over to a U clamp as well.

Zoo,

The registration pallet would be similar to the Tri-loc pallet. 3 bump stops and can be used with any type of screen, for presses without pin style heads. (Keep in mind I don't have this in my hands yet. I'm going off what I understand it to be).

TCT,

Are you using the S Roque PRU system? If so how do you like it? Have you ever used tri-loc before?

EB,

What are you using for pre-reg?

[ZooCity]

Thanks, I might look at one.  We're using the Newman system and frankly, it's been more of a pre-position than a pre-reg outfit.  We use a tri loc on the presses.  I wanted to tighten up the film to screen part and was going to build but would just buy on of these instead if it checks out.

[TCT]

Never used the Tri-loc, so I can't compare. We are kind of using the PRU, our PRU is set up for the pin system. It seems to work just fine with the U clamp though since everything is registered exactly the same. We are just waiting to get our CTS set up and then the PRU will just be for oversized screens.

The knock on the S.Roque reg pallet I have is that a "XL" reg pallet won't fit on a "M" machine out of the box.... A drill, 4 rivets and careful measuring takes care of that though!

Are you looking at getting the pallet? Or the actual PRU? What kind of press are you using it on?

We use the MHM fpu for our two s types. Basically the
exact same as Roq's pin system. Was planning on having our Roq
made with MHM compatible holders, and continue to use the MHM system
for all machines, but then found that the MHM pinned frames will work in
the Roq PRU, reg pallet and u-clamps. So that's what we'll be using in a few months.
Best of the mhm and mnr styles, like screen printers have been discusing and cobbling
together for the past few years.

We use the pin system with the PRU. Looking forward to hear other experiences with the reg pallet vs pin system.

I haven't personally seen the pin system in action but I know regi systems fairly well since I've been trying to perfect our systems for years, and I feel like the pin system of Sroque's is inferior to the U clamping system despite having to put a regi pallet jig on for each setup.  If done correctly (human factors) the U clamp should be more consistent and also accurate due to the difficulty of some machines having problems reaching a true micro zero.  With the micro systems on the Sroque and MHM finding zero is MUCH easier versus other machines but it still has room for error that you really don't have by butting a screen up to stop blocks.

If I were buying an Sroque I'd be opting for the U clamp system without a question.  Plus you don't have to put the pins on all your screens which should count for a lot in larger shops with hundreds of screens. 

Just my humble opinion and I'll remind everyone again that I don't run an Sroque or MHM, just a modified triloc on an RPM that is unbelievably accurate.  I've got numerous test prints in my desk of 6-8 color jobs that were dead on with one test print and our average color count is 3 colors right now so our setups are routinely under 5 minutes with most of that time putting squeegees, floodbars and ink in the screens.

Shanarchy, I would use it like Alan does,  fpu for film alignment, tri loc on press.  I think any accurate three point jig is fine for reg on the machine so long as the films are aligned.

Agree that true zero is the problem with pin systems.  Some micro styles cannot zero well.  But on the machines with accurate micros I don't see why a haptic or visual indicator couldn't be used to ensure heads are at true zero after each job.  I find loading a reg platen annoying.

I have the U clamps.

My options are:

Using tri-loc (which I have), swapping out the pallet with the S Roque registration pallet which I've already ordered. (I'm assuming it will work the same).

Or:

Order the PRU positive registration unit. Which would be also be made for a U clamp press. And would utilize their registration pallet. This does not use carrier sheets. And I wouldn't be using any part of tri-loc.

Find a used MHM unit on the market. Hell, I had 2 of them at one time! You should be able to find them pop up with people going CTS. SPSI has 2 they've been sitting on for 2 years.... Probably be a cheaper option if you are looking for that.

Alex,

Woukd that work with a c clamp press? I'm imaging I should be using ones with bump stops to match my pallet as opposed to pins, no?

What should I expect to pay for one of those bad boys on the used market?
