Interdependant variables

[tonypep]

How many can you list and how they affect eachother? Presses, inks, chemistry, procedures et all. Everything.
It may be a long and broad entry however I am interested in everyone's stories about what worked and what may have not.
My experience has often been one of "Fix one problem and cause three others!" Products and suppliers do not need to be mentioned.
I have my experience with stick what works and then, change comes along. For better or worse, it comes hard at times. When it works it can be like magic. When it does not, well not so well.
If you have the time please list your thoughts

Tony, love this idea.

So many variables can change so many aspects of things on press. We've recently begun the switch from statics to rollers, so we can control and make our tension uniform. Hoping this speeds up registration and ink release.

Thanks Eric. The ink release is quite dependant on the viscosity and rheogly of the ink, mesh tension, squeegee variables. Many slightly older presses have different deflection and are hard to determine and adjust for. Rollers are better but are not great if they are not kept up!
Think of things like print sequence, flashing etc. I visited a plant where they had three flashes and the platens were hard to even touch.
Perhaps we can talk about mesh counts now? Or squeegees, or ink, or presses?

Very True. Heat is def. our friend with HSA and WB, so warming up those pallets helps with the release. I do agree Rollers help, but need to be maintained. We are switching back so we can keep uniform tension across the board!

Glad to see the switch back to controlled tension!

maybe we can get a trend started again

We are in the middle of the switch to rollers and already seeing faster set ups.

My shop isn’t big by any means but I never quite understood the trend towards static’s. Frames require work either way so why not have the ability to keep consistent tension?

Count me in for the roller trend. I never left it

ok Big Dave... Chime in, the door is wide open for the discussion you have waited 2 years for!!

I can't say anything. If the trend to rollers for more control continues, a lot of people would have to say I may have been correct.  Mike drop.

Speaking of fixing one problem to find another and rollers.....My first experience with rollers was a doozy. Got my table in and M3's. They were old (like 30 years old) and I needed holders for the frame corners - $600. I then proceeded to level the table and stretch some mesh. Just got my auto and had an 800 piece sim process order due. I'm ashamed to say I tried to register that thing for 5 hours! I was pissed. Thought it was the press. Nope. Frame wasn't flat. I levelled the table but NOT the metal pieces where the corners of the frame sit on the table. Fixed that. Then had a supplier send me some statics with the Newton's they were stretched to written on the side. My meter was off from that so I adjusted. Don't do that. Learned that it was out of calibration and even if I adjusted the dial to match the frames Newtons that isn't calibrating it. I've now got 2 meters in house that I just got back from getting recalibrated. Bought one off eBay and had them send it straight to stretch devices. Got another just in case I drop one, etc.

I'm much better now with rollers. Use all Hidro. All my statics that had thin thread came in at 28 and are down to 20 in about 2 years. At least the ones that have survived. I've had better luck with thin thread on rollers than I've had with Statics.
