You're talking about screenprinting right? Are you using a heat press, and pressing all the way down? I think one of the new methods for using a heat press with screen printing is to come down to an inch or so before the t-shirt and stop. Don't come down all the way.
If you have to come down all the way try a silicon sheet or pillow case between the top platen, and garment.
Otherwise, the yellowing should come out in the wash. You can try one, and throw it in the was to see.

It's for the pre-treat with the direct imprint ! on the navy and black shirt after drying pre-treat i have a square the size of the heat press mark on the shirt ! does it come out with some washes or maybe someone have a method that don't do that square after the pre-treatment !
I'm sure it does come out. Just to make sure wash one to see if it comes out. You don't want to chance it. The customer may ask, then you have an answer ready. You can also talk to the vendor that sells the Pre-treatment.
DTG Pretreat will leave a residue square on any and all shirts.. it will come out.
Nothing to fret about or worry about it will wash out. Most customers usually wash their new shirts before they wear them so they won't notice after its washed.
If they do notice please let them know it washes out.. nothing you can do about it.
It is more noticeable on white shirts but again it washes out.
if you dilute your pretreat the print will not last as long .. if you change the temperatures or mess with the curing times again the print will fade faster..

You can also reduce the spraying of the pretreat a little without reducing the longevity of the print. But the best remedy is getting a larger heat press so you can press the whole shirt or a tunnel dryer. We have 2 customers with the vastex econred II infrared dryer with air scrubber. They work fantastic.
I got a beautiful 4cp print with bright white inks from a manufacturer as a sample. I am looking at buying their machine for darks, I have done about 15 washes maybe 20. Upside of having lots of kids tons of laundry so it goes in like 3 times a day. The pretreat sqaure is slightly visable but what is really weird is it is a lint magnet. Cant see the pre-treat but can see the box left from heat pressing and now every bit of lint collects in a square around the print. has anyone seen this, will it go away. the print is awesome, colors have not cracked or faded but that darn box of lint makes me nervous. I want to ask what type of pretreat they use and how they apply and if there is a substitute. I guess using a conveyor oven and pretreat machine may help but it is just weird. Best print sample I have ever seen but each wash/dry causes more and more lint to group around the print.DTG Pretreat will leave a residue square on any and all shirts.. it will come out.

Something has to be available to make this stop, maybe a smaller heat press or oven or different pretreat. Has anyone ever seen this lint issue from pretreat??
One, don't dry in the dryer, just wash and hang.
Two, did you say you use a Silicone Sheet between the image and upper Heat Press Platen?
You can also cure by pulling the heatpress down, but stop before touching the t-shirt, and hold with a little air gap between both. It will still cure, and won't leave a square burnt mark. You can also try a heat gun. Looks like a blow dryer, but heats up to about 400 degrees. Some have a tempature guage built in.
I've seen a video from youTees.net I think, and the guy mentions using a Heligon 500 watt shop lamp to dry. Haven't tried it, but he swears by it, and also using the home oven. Hope he Microwaves his food though.

When you dry your pretreated shirts in a heatpress (with pressure) it will stain some shirts and completely discolor others. I have found that the end result varies depending on the shirt manufacturer. I line dry all of my pretreated shirts prior to printing on them. If I'm in a pinch, I'll toss it on my heat press but only hover the iron for about 60 seconds instead of locking it down like Selanac said. Regardless of if that square stain washes out, I can't give shirts to a customer looking like that.
Thanks CoorsDTG, couldn't remember the term, Hover.
yes ok but if you don't press a little bit on the shirt the fiber wont be flat , the will leave some hair after the print ! you don't have that problem COORS DTG ? every body said to me even selanac to press not to much on the shirt with the pre-treat ! so now i'm confuse !!!
You can also set up some barn doors on all four sides of the shirt to block the pretreat spray where you don't need it. Then get a set of those heat press pads that you lay down on the heat press for smaller areas.
Someone was advertising those heat press pads on this forum.

You can press before the pre-treat also.
What type of garmet are you using? Are you talking about towels, t-shirts or pull overs? We have to remember that some products come with more fiber so we can't compare Apples to Oranges, or for this example: Terry Cloth, to T-shirts.

i'm using gildan ultra-coton t-shirts !
it looks like you got a bunch of helpful hints..
really my suggestion to you is do what makes you comfortable in your pretreat process because if you ever get a larger order or you are behind ..any extra steps that throws you out of sync is gonna cost time and money.
Yellow, Red and Oranges shirts you will see this problem more than you are now.
So do what works for you and explain to the customer if there is any problems or put a note on your invoice under your disclaimer.

Cool thanks for all the info !!!
Earlier I mentioned using a Silicone sheet, but it's actually a Telflon Sheet. I bought some of ebay for about $6.00 USD., each. I think I bought around 3.
When we first bought our DTG, I think we paid $20 USD for one.

Use a clothes steamer if a customer complains and let dry, it should do the trick!
