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

Re: problems with 3G Jet-Opaque transfer paper
 
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

Re: problems with 3G Jet-Opaque transfer paper
 
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.

Re: problems with 3G Jet-Opaque transfer paper
 
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!

Re: problems with 3G Jet-Opaque transfer paper
 
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.

Re: problems with 3G Jet-Opaque transfer paper
 
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?

BroJames September 24th, 2011 03:34 AM

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.

BroJames September 24th, 2011 05:35 AM

Re: problems with 3G Jet-Opaque transfer paper
 
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.

hotmama September 24th, 2011 06:05 AM

Re: problems with 3G Jet-Opaque transfer paper
 
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
http://i7.photobucket.com/albums/y29...s/neenah3g.png

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.




BroJames September 24th, 2011 07:53 PM

Re: problems with 3G Jet-Opaque transfer paper
 
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.

Re: problems with 3G Jet-Opaque transfer paper
 
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..

yolo creative December 29th, 2011 01:35 AM

Re: problems with 3G Jet-Opaque transfer paper
 
We generally recommend 3G Jet-Opaque for use with 100% cotton and Jet-Opaque II for cotton blends. As your shirt is 60% cotton and 40% polyester, you may find that you getter better results with Jet-Opaque II.

Emvy December 29th, 2011 01:41 AM

Thanks you very much! I'll definately try that..

What sort of color adaptation problem? 3G is opaque and there shouild not be any color adaptation problem as I am imagining the problem to be. Meybe you can be more specific.

Whether it is better for use with cotton or polycotton shirts is another matter.

Can you elaborate further? TIA

Re: problems with 3G Jet-Opaque transfer paper
 
It is actually dye migration. The dye on cotton blend will sublimate thru the opaque. Try pressing it twice and let it cool in between presses. Split the time in 2 halves. Press for first half. Let it cool down for few seconds then press with the second half. Lower the pressure also. Otherwise use 100% cotton.

BroJames December 29th, 2011 05:26 AM

Re: problems with 3G Jet-Opaque transfer paper
 
Does the dye migration occur after pressing or soon after?

I use 3G and jet opaque interchangeably but more on 3G. My opaque papers on stock is 3G. I used to press at 350F(176C) for 15 sec then repress for another 15 seconds. I recently change to 190C and 10-12 seconds + 5 seconds repress. If I pr4ess for 15 seconds some edges won't stick. I believe that is a sign of excessive heat(or is it?). Pressure is medium to hard. Shirt is usually 60% cotton. I did not notice dye migration but will try to observe more closely next time.




Emvy December 29th, 2011 07:04 AM

Re: problems with 3G Jet-Opaque transfer paper
 
For more elaboration, the paper is tinted with the color of the shirt.. the shirt is pink and the image on the paper turned pink as well..

Lnfortun December 30th, 2011 12:59 PM

Re: problems with 3G Jet-Opaque transfer paper
 
Dye migration occurs when the dye molecules are heated at high temp and prolonged time to a point that the dye turn to gas state. While the molecules are in gas state they will bond to the molecules of synthetic materials. When cooled down the dye molecules return to solid state and permanently bonded to the synthetic material(sublimation). Although opaque material is not as receptive as 100% polyester synthetic, such as 100% or high percentage polyester shirt or 100% polyester coated material such as mug, it will have some form of sublimation effect(dye migration). So when splitting the time and lowering the temp when pressing opaque the dye molecules will not reach to gas state. Therefore minimizes the possibility of dye migration. Some vinyl transfers have some form of dye blocker to prevent dye migration.

I treat opaque material like vinyl transfer. I press between 320F to 330F for 6 seconds for first pressing. Let it cool down. Press 6 seconds for second presssing then peel cold.

Over heating or pressing too long can overcure the adhessive and lose it's bonding property. That is what happens when the edges are lifting.

BroJames December 30th, 2011 06:58 PM

Re: problems with 3G Jet-Opaque transfer paper
 
Although mine is not lifting up at 12 seconds seems like I can afford to lower the press time.

Re: problems with 3G Jet-Opaque transfer paper
 
Did you ever get your image to stay put?
Normally the 3G is only used on 100% cotton fabrics. If you're using that 60/40 blend or any other blend then you may want to think about using a different opaque paper - try the Blue Grid or the Jet Opaque II paper. Those won't be quite as soft but they will give you a great vibrant color.
Also, temp should be around 170-175C and press for around 30 seconds. Also use a medium pressure for the 3G as well as the Blue Grid and the JetOpaque II If the paper won't stick to the shirt at all after pressing, make sure you've peeled the paper backing off before trying to press it?

That should be 180C.

I started with 176C 30 seconds but the edges sometimes lift. I've tried various temp-time combination, including some used by commercial printers. The lowest temp I recall is 160C 30 seconds and the highest 220C 5 seconds. Most seems OK but without the benefit of extensive wash test.

For a while, I used 176C 15seconds press plus 15 seconds repress. That seems fine too. But the shirts I've wash test most was pressed at 180C 10-12 seconds + 5 seconds repress(sometimes none). I maintain 180C for paper transfers and vinyls (Chinese polyurethane) except some korean vinyls that require 110C 10 seconds.

Frankly I printed mostly on black cotton blends but have also printed on grays, yellow, red and a few other colors. I've also printed on 100% cotton. Unfortunately, I did not pay special attention to possible dye migration.

How does Blue Grid or Jet Opaque II compare with each other? Have you tried paropy or joto?

BTW, my current problem is opaque papers cracking after 20 or so washes.

Yup I don't follow for the most part the instruction with opaque. I find much lower press time solves the opacity issue. 30 seconds is way too long. I press between 6 to 12 seconds with opaque depending on brand name.

BroJames June 19th, 2012 11:12 PM

Re: problems with 3G Jet-Opaque transfer paper
 
I also find the lower press time, although a little bit longer than Luis', better. You should also know your press as even two same models from the same manufacturer can have 2 different "ideal" time.

If a transfer is peeling after wash, assuming a quality product which this is, then the issue is typically, time, temperature or pressure related. Assuming you followed the instructions with respect to time and temperature then I would suggest more pressure on your heat press.

The press time, temperature etc. are available in the instructions. If you don't have them, they are on our website under instruction sheets. If you are following the correct press time and temperature then you need to increase the pressure on your heat press.

Hey guys... I just started experimenting with my JW 3-G Opaque transfer papers.. Using MIS HT inkset (8 colors) pigment ink, Epson Stylus R2880, heat press set at 350 degrees F for 30 seconds at 6 pressure. I let the print sit for 20-30 minutes before pressing, and placed parchment paper between TP and shirt (Tultex 100% cotton ringspun).

With the above mentioned actions performed, I can't get my transfer paper to stick!! Soo frustrated, any suggestions???

Also, is there a particular plotter brand anyone recommends? My x-acto knife is just not "cutting" it. Heh.

The transfer and shirt will over cook if you press taht long. Your heat press actual temp might be different from the display. Vary the pressure or temp or time. Use between 6 to 12 seconds. Lower or increase the pressure and temp in small increments. Cut up a blank transfer in small pieces so you don't waste transfer and ink. Use each piece on scrap fabric for testing to find the sweet spot.

I don't use suggested settings. The settings will vary from suggested settings between different heat presses. I use 6 to 12 seconds with opaque to prevent over cooking the adhesive and minimize dye migration on cotton blend.
