More S Roq questions for users
« on: February 03, 2016, 10:02:38 AM »
Hey gang, as I'm dialing in my settings I'm curious to what other people are running at. I know this will vary grater from shop to shop as we run different, mesh counts, tensions, t mesh vs s mesh, inks, squeegee rubber, and expected results, but I'm interested in what others do as I basically just try to figure it out as I go.

What are the settings that you are using for white, and for top colors?

Squeegee and flood bar height, speed, and angles? Pressure? Off contact? Double or single stroking?

Also what squeegee duros, mesh count and appx tensions you run at (if you know).

I feel like I'm getting close, but I'm still not quite where I want it to be. I do love this press though!

Thanks!

Shane

All would depend on what we are printing(sim process, hsa, athletic print, spot print, etc)

I'll start with what we do on a white flash white solid area lots of coverage -

150/48 underbase screen - approx 25% eom stretched to 25 newtons

Squeegee settings - 70 single duro blade

10 angle, chopper depth set to 3 mm from 0. Stroke speed will depend on the ink your using. Cotton shirts we are using nexgen white running at dial 7 on speed, for our low bleed ryo white we are running at 3-4 on speed) The faster you can stroke the ink the better it will look. A lot of jobs depending on the mesh if we are using nexgen inks we can run them at 100% speed.

PSI on the gauge should be around 40 psi

Flood settings -

20 angle, chopper depth set between 5-7(again this depends on the ink) and depth of floodbar should fill the stencil. To fill the stencil better create more angle and drop the depth closer to 0 setting.

Off contact is set to 2mm

Single stroke that screen, followed by flash(flash is super critical IMO for proper mat down) then put your 2nd highlight white on a 225/40 screen(same tension, same or similar eom) and on that screen we run slightly less angle, pressure, and more speed.

PM or email me if you have any specifics and would be happy to help where I can.

Thanks Danny! This is awesome info! I'm using S mesh in 150/180/225 around the same tension as well.

The problem I ran into before posting was screens popping on press. Two of them. Same spot. It was where the flood bar was hitting the mesh. So I figuring either the pressure, height or angle. So I'm backing off all three for now (and crossing a finger). Is 25 degrees too much to run the flood bars at?

The 25* is too much angle IMO..... We popped a couple screens @ 25* and brought everything under 20, no issues since. I would personally not run the flood over 20*

The tech told me 25 was the only angle you could run the winged flood bars at hahaha
No biggie, he was a super nice guy and did a really great job on the install. I'm glad to hear that is the reason as it's an easy fix. I'm also glad the micros are pretty smooth so it was pretty quick and easy to re-register the replacement screens.

the angle of the floodbar is ripping the screens?
Make sure your wingtips are floating above the mesh, they don't need to be touching to be effective.

Yes, we've won our share of awards, and yes, I've tested stuff and read the scientific papers, but ultimately take everything I say with more than just a grain of salt! So if you are looking for trouble, just do as I say or even better, do something I said years ago!

That seems to be pretty much exactly it. They were set where the wing tips were touching/dragging along the mesh. We're going to angle them up how Danny is running his. Sounds like it will do the trick.

25 degrees is what we run our flood at too.  Danny and I are running the same screens,white ink and I concur on those settings.  However, on anything other than the Next Gen ink (which is the best white out there IMO) we have to run 50-60 psi.  We did just change our blades from a 70/90/70 to a smiling jack today and that has allowed us to drop our pressure, at least on the Next Gen.  All of our colors we run at 15 degrees on the squeegee and 8 flood, 8 print.

When I first got my Roq, I was popping screens all the time and I thought it was the flood bar too.  However, I realized we were not rounding the edges on our squeegees and this was causing the issue.  If it is the flood bar, make sure your flood depth is set to 1.2-1.3.

I was concerned that it was the squeegees because I did not round them. Which I should. Are you using sandpaper? What grit? And how rounded are we talking?

How are you swapping your squeegee rubber? Are you squeezing them into that stock holders or did you get different ones? I ordered two of the action ez clean ones today so I can start using other squeegee rubber. I'd like to swap out to triple duros and eventually try smiling jacks (after I'm dialed in).

The above picture had a smaller squeegee in it that the blue. They both popped at the same spot where the corner of the flood bar hits it.

I trim mine with a knife, I don't know how others do it.
As far as replacing rubber, it's a chore, at least on mine.  Depending on the year of your machine, (and I think you got the last one from Tech Support correct?) they take different sized rubber than most presses.  Make sure you get the right size.  I think it's 9mm, or maybe standard is 9mm and old Roq's take another size, can't remember off hand.  If you have the old one, you'll have to do some reverse engineering to get smiling jacks in, but the ones from action I think come all the way apart if I'm not mistaken.

Check your depth on your flood bar.  I think it might be hitting too low.

Standard is 3/8, ours are 9mm. Did you find a place to source 9mm triple duros?

I have 3 coming in from action one with a 70/90/70 the other with a 60/90/60. I'll use the for white and the normal 70's will stay for now.

Correct, mine was the last tech support one.

I'm not sure whether I fad the flood bar height before, as I moved them both. But I'm going use you and Danny's specs as a guide to hopefully avoid popping any screens.

9mm is what you. Tech support should still care serilor, if not they will drop ship.

FWIW, all the new Roq's come with the standard sized holders for squeegees. Finally realized it was easier to standardize them with all the other presses (except MHM I think?).

Judging based on that picture it was your floodbar. The edge tip of the wing at 25* is touching the screen and there's absolutely no ink on the wing of your floodbar. This is why we do not run 25* in my shop because if someone doesn't have ink where the wing contacts the screen the friction you create will damage mesh often. It will keep the ink in the well better but for production much less risk running a touch less angle imo. I'd suggest rounding your squeegee blade edges and run a tough less floodbar angle just in case your wings don't have ink on them.
