Since the gallery is screaming that you cannot print fast sheering ink on a roq due to the single pivot squeegee I figured a quick video would prove otherwise. Nothing special here, standard block style print using good mesh, good ink(new wilflex white from ryonet), good blades, proper off contact, etc....... I only have one operator on the press so the indexing is delayed otherwise this print would run 1000+ pcs per hour easily.
Squeegee speed is maxed out on both the underbase and the top white.

nah dude, we turn ours up to 12!
-
Like you mentioned already, the stroke speed look great.
I recently saw one run at 1092 per hr. That was a 1 Clr black ink on an M&R tho.
What mesh,
What squeegee?
what squeegee angle?
What off contact?
-
Our squeegees go to 99. WB only though.
Danny our Eco maxes at 1600/hr, are the new ones faster than that?

The Eco1600 is the fastest one right now, our eco here is a 1200 model but we can run 1000 pcs per hr on it often.

Good to hear, I don't have to be jealous now.
We hit 1600 for just a minute the other day. Small LC.

Seriously,
What mesh?
What squeegee?
what squeegee angle?
What off contact?
Reason being, I want to see if what you are doing matches up to what I was telling some people they should do.

This job was done on 150/48 thin thread mesh - 25 newtons
Squeegee is single duro 75
Angle of blade is around 8 degrees
Off contact is 2mm
Wilflex white yet to be released

White looks very white and smooth. Much brighter (like perfect) than what I had recently seen done on a regular 156 base and top white using a 70/90/70 at vertical angle at 1/8th" OC.
so both the 150 S mesh and this ink offer great results.

Liking the white better than the synergy?

Yeah I will say if we were printing this on a regular 156 mesh we would be running half the speed and the print wouldnt look near as good...... Mesh in my opinion plays a HUGE roll. We still have some standard 156/160 mesh in our shop here and I literally cringe when I see a job on that mesh. Using standard mesh is like trying walk with your feet tied together LOL
-
Nice. 150s for base and hilites?

What is your pressure set at?
If I could actually get the dip out of the front of my pallets fixed we could run it maxed at as well, but since we are not parallel we have to compensate and slow down a bit.

Our air pressure is right around .3 and our depth adjustment is set at 3mm from 0........

We have a Roq You and generally print everything at a squeegee speed of 10, and single stroke.
For white ink we use IC Legacy
150/48 S mesh
Angle 5 degrees
Off contact 3mm
Squeegee either 55/90/55 or 70/90/70 depending on desired results/coverage

How does that ink compare to the Wilflex Epic White? I quit using the Synergy cotton white, it looked great but took three passes on the 180S. We have switched to Epic Tiger ink and am now clearing with two strokes on a 180S. I have some 150S mesh coming soon so I am excited for them to arrive.
-
I've just had a conversation yesterday with an ink guy that is the R&D guy at one of these ink companies. Doesn't matter what ink co. cuz he feels the best coverage is not so much about press setup but more about the stencil. Thicker stencil, better coverage and stroke speed.
(I think) and in sure he would agree, it's more about a combo of all these things. A good white helps all that much more.
-
Also a super sharp squeegee blade does wonders as well. I've started taking the time to sharpen more often. Most of my simulated jobs the underbase is on a 225/40 s mesh with epic white. It's clearing with a single stroke at around 40 psi with my stroke speed set on 7 "whatever speed that is on the sportsman".

Had a conversation many years ago with an ink guy..
tells me The problem isn't the ink, it's the idiot holding the bucket that makes it a problem.
The single most talked about thing in this industry is white ink..
We have a test print at the booth for shows.. it's a 45newton 102 mesh with some good detail. It's the perfect stencil printed with a constant force squeegee. I could put any white ink and make it print perfect.
the first thing everyone ask when they see my 1 hit white... what white is that?
never has anyone asked me about the stencil, or how i printed it.. I have to tell them.

I'm still stuck on the 1600pcs/hr thing. Loading that must be like trying to jump on a moving train... Surely this sort of speed just puts all the staff in a state of panic?

I hear all of these high pc per hr numbers and the best I've ever loaded was 648 per hour but that was only for like 10 minutes. Honestly here on darks we print at usually 400 per hr. I am the only loader so I'm the bottle neck of the whole process. Maybe I need to hire a woman to load since I've heard here somewhere that they do a better job. I know it's a bit off topic but I had to spit that out.

I was running 92 dz an hour in 1994 on a tuned up gauntlet 6 color.. that's 1104 and hour and i felt like i was waiting for the machine.
Fast forward to 2004 with a brand new Challenger II 14 color and with the help of rich.. he helped me tune it to 102 dz per hour.. and I then ran that machine consistently in the 90ish dzn range for a couple more years before leaving that shop.
Loading shirts isn't that hard, having a job that will run non stop for an hour or more.. that's the hard part.
the most i've loaded in an hour was 1216 and the most in a 24 hr period was 10,001. (22 hrs and it was at mirror image when the red sox won the series. to this day my left knee still feels that day)
-
So far my top speed on our GT3 has been 1164 per hour for a couple hours, then back down to 1000, then tap out for Niki to jump in. The machine can run waaay faster than that, but honestly, I don't see how to maintain perfect loads and qc by the puller much faster. We ran a stickee lint screen and 150s mesh for a nice deposit. I tell you what, that will kick one's arse quick lol, but when you have pallets of shirts and a short short deadline, let adrenaline take over lol.
-
That's incredible. Is this volume managed with 1 loader, 1 puller and 1 catcher?
