Print not holding up after one wash
 
1 Attachment(s)
This print started coming off the shirt after one wash from the customer. Not sure how the customer washed it. Since we are new to printing with white ink, I was wondering if anyone had this problem before and how they corrected it. Our process on these shirts is:
30 sec heat press @ 356F
spray 1 layer pre-treat-roll with sponge
spray 2 layer pre-treat-roll with sponge
heat press 35 sec @ 356F
print
hover 1 minute (we don't have a hover press yet so I feel we are not getting very close to the shirt)
press w/ light pressure & silicone paper for 2 minute @350 @ 1 minute intervals

Try curing for closer to 3 - 4 minutes.

Also make sure it isn't washed in hot water.

My guess is it's more in the way you are pretreating. I personally use 100% pretreat with a Wagner gun spraying in one direction with moderate speed. It's coated and it works well. I don't use the roller, I know some do, but time is money and I think it takes too much time to do.

Do you think I should lower the temp if I cure it for longer?
Sometimes the prints get this "cracked" looked after the 2 minutes.

Can you use too much pre-treat?
With the Wagner do you do one pass?

We are, for now, using a hand-held spray bottle.

If it's a plastic bottle, too many times they are too inconsistent. My advise would be to go to Home Depot or Lowe's and purchase a wagner spray gun with a dual tip. $60-$80 with consistent spraying. When you are finished, run water through it and you are set....

Will do! Thanks!
Do you think my curing times/temps are good?
I think I'll try different times/temps and give them a wash.

What brand of shirts are you using?

I think the times are good, although I don't think you need to hover for 1 minute, 20-30 seconds should be fine. And yes, Kevin has a good question.... ;)

I agree with Marc and Jerid's thought process. In my experience, if large pieces of white underbase are coming off the shirt... the issue is too much pretreat fluid that created a blocker to prevent the binders in the white ink from adhering to the garment. If the color ink comes off and the white ink stays, then I would say that it is an issue of curing the ink process.
