I am using Wilflex White Buffalo and I am having an issue where the ink is going outside my screen image. I have adjusted pressure to where it doesn't clear the screen, off contact, squeegee angle, adjusted flood bar and I still can not figure out what to do. It seems worse on the press side of platen and on the left had side.

something is loose...that is way off.
Check your screen holders and your platens
-
Try wiping the back of your white screen. Sometimes when changing pressure and adjusting some gets picked up off of a previous print. Pretty simple but often overlooked.
-
Wow, off in both directions! It ain't the ink.
-
Is the screen tight enough? Try more off contact and a fast print stroke. Maybe less flood too.
-
Both directions is really bad, my first check would be is the screen moving, second thing would be to make sure I am not printing while flooding. Thats if you flood with table up. Definitely make sure you wipe the screen after each adjustment other wise you will get false results.
-
Its on both ends as I did less off contact and changed the angle of the squeegee. The screen is 30n. I wiped off the back of screen and its there next print. Sonny called and I will make sure everything is level. This sample is the worse one.
-
Could be too much flood pressure.

Could be too much flood pressure.
Thats what I was thinking as well. Pushing too much ink through and getting bleed all the way around.
-
Are you double stroking the white?
I have had issues not quite to the extreme you have with this print. If you have too much pressure on the flood of the second white screen you will get that ghosting of the image.
-
looks like the screen isn't being lifted up when for the flood stroke.. almost like it's being printed in both directions

This may be a weird question...but here at my shop we are having problems with static electricity..i have no idea what to do about it..It really messes with the ink..it did on my manual and now it is on the auto..when the screen lifts you can hear the that static electricity..We use Union inks..
Near the holidays we were printing sweatshirts...print was fine when i took it off the platen, put in dryer...came out looking like yours...happened 3 times...and yes i checked everything with the dryer..plenty of space and what not...
Just a thought, because it looked like yours..
-
Here it is...trust me when i say it printed fine ...
-
not doubting you, but i have been in a print shop since i was a kid and I have never seen a shirt that goes in fine and comes out double printed. Sorry, I just don't buy it. You shirt shrank between coats of white.
Smearing on the dryer gate is another issue.
Actually, I am doubting you. ;)
-
Whites pick just above clearly looks like a lack of adhesive in just the top corner, heavy sticky white ink probably caused a shirt peel and then the next coat was off center.

This is why when I drink it is at the end of the run and not during. Everything looks great when you have a buzz............. ;)

Get a humidifier, it will solve the problem.

Only one screen. Double stroking.
-
no adhesive?
too long on the flash?
loose mesh?
loose screen holders?
too much flood/squeeg pressure?
loose platens?
ripped screen?
too much squeeg angle?
Loose squeegie clamp?
I got nothing else.
second look, I'd put my money on something loose/broken...
Rob - you don't have enough adhesive on that side of your platen...my guess...we have static too, we just grounded the press and it's fine...my opinion anyway.

PFP as well? Is any part of the pallet exposed where the screen can stick to the glue? I have see that happen when printing tramp stamps.
-
Jay...how do i ground the press?
-
Jumper cable on bare metal jumped to a grounded piece of equipment like your oven. We often have to ground our flatstock drying rack and putting lexan or other flatstock on it or pulling it off can build up enough static to see blue arcs jump over an inch.
Seriously though a small humidifier in the shop will work wonders and make it a more comfortable working environment to boot. Static can't build up with a decent humidity load in the air.

I got shocked one time by one of those really long ones...right on the nipple. That nearly brought me to my knees.
