problems with 3G Jet-Opaque transfer paper
 
Hi! A newbie here from the Philippines.
May I know the factors that would cause the peeling off of images, printed on 3G Jet-Opaque, after several washing of the shirt.
I followed my supplier's instructions: for dark transfer, use 130C for 15 secs. I also stretch the shirt before and after pressing which I read on the threads here.
Any solution for my problem, pls... Thanks in advance

According to my instructions, you should be pressing the 3G Jet Opaque at 175C for 15 to 30 seconds. I normally average 25 seconds.

Have a look here for full detailed instructions: yol÷ ? 3G Jet-Opaque« T-Shirt Transfer ? Heat Transfer Paper for Inkjet Printers

Thanks for the link, Gigworx! This is really helpful.

By the way, since I already printed a black shirt with this setting, can I re-press the shirt again? Or should I just advice the client to inform me if the image peels off :p It's been 24 hrs since I heat pressed the shirt and I haven't given out the shirt yet.

You could give it a try, make sure you cover the transfer with parchment paper or a teflon sheet and after pressing, remove the paper carefully.

Remember also to tell the customer not to wash the garment for at least 24 hours after pressing. Ensure that the do not use liquid softener in the wash either, this can eat the emulsion used in the transfers.

My problem is that it WON'T stick at all!! Do I have a bad batch? Followed instructions to the letter!

I am also from the Philippines and I can't quite understand why suppliers here tend to recommend a lower temp and pressing time. In my case, I was recommended 165C and 20 seconds.

Is 175C and 15-30 seconds the manufacturer's recommendation or the distributor's? I seem to recall its 30 seconds heavy pressure.

I'm from Philippines also.. and i also use 3g Opaque at 175c & 10secs.. im 6mos at the business & at the said temp&time i never experienced a failure on ths transfer paper..

btw, i might be on a wrong thread but can you guys watch this video (How to start your own t-shirt business - YouTube) & if you notice the transfer paper he used at the black shirt, it's a like a self weeding but the guy on the video did not mention the name or the brand of that paper, did anyone here tried that paper before?

Re: problems with 3G Jet-Opaque transfer paper
 
I just checked the neenah website and the official recommendation is 177C for 30 seconds using heavy pressure. I also talked with a major distributor of neenah and I was told lower temperature and time will last careful washing but not rougher washing. He said that in their case, for testing, they soak the shirts on Ariel which is the most "destructive" detergent locally and wash inside out even scrubing on where the image is. And the 160-170C and 10-20 seconds setting won't pass such "torture test"

The manufacturer recommends 30 seconds at 350░F using medium pressure. 350░F is approximately 175░C. We recommend a pressing time of 15-30 seconds in our instructions as the ideal pressing time can vary depending on the type of fabric you are applying the transfer to.

I just recheck neenah's site and it recommends 350F 30 seconds and heavy pressure.

You'll find Neenah's instructions here: http://www.neenah.com/technical/heat...t%20Opaque.pdf which recommend medium pressure.

Thanks, guys!

I guess we have different settings that we follow for 3G Jet-Opaque.

I know this is out of the topic, but I would also like to know your settings for Jet-Pro Soft Stretch. I would like to maintain one heat setting for both types of paper but I'm clueless on the time setting. One more thing re: pressure, I set the pressure of my heat press "mano-mano" meaning manually, since the machine is not automatic. Is there a way for me to somehow set the correct pressure setting? I guess in my case I'd stick with heavy pressure.

Thanks in advance!

I am unable to connect to the link on my computer but I am takingyour word fot it. This is what I saw at neenah.com Specifically this portion

Yes hotmama, it does seem that there is no single setting that works. Some opt to raise the temp and lower the dwell time. Frankly, I have pressed 3G at 110C for 25 seconds or so and it withstood several washes. My son is still wearing the shirt, the transfer still unscathed, for about 10 washes now. I am just wondering which is the official recommendation.

As for Jetpro, I am finding it to be more sensitive to different settings. I do know some people pressing them at 220C for 5 seconds.

Just saw this on neenah's website. . I think this is the page that yolo provided. It reads
http://i7.photobucket.com/albums/y29.../neenah3g2.png
I do see medium pressure but the the time is 30 seconds and not 15-30seconds.

The brand of the press will also definitely have a bearing on the transfer.

After trying all the instructions varying the temp and time.. I still have this problem of the transfer paper adapting the color of the shirt. I use a 3g Jet Opaque and a Yalex colored shirt.. 60% cotton 40% polyester..
