AS Colours 100% cotton shirts don't discharge

This is a reply I got from my rep at AS Colour about discharging their shirts

"Like most forms of decoration on AS Colour garments, they can’t be treated the same as a Gildan tee etc. as the quality of the cotton and the weave of the fabric and the general all round quality of the garment far exceeds the others and will need to be approached differently. Same goes with DTG on our garments, they will require slightly more pre-treatment than you would on a Gildan tee etc. and generally a higher curing temp.

It is possible to achieve bright whites when discharging on our garments, they just require different attention than other garments that your printers may be familiar with. Factors such as pressure on the autos are a massive factor as AS Colour garments tend to require a little more pressure due to the finer weave of our garments. As you know, a finer weave means a finer print, but as discharge needs to be embedded into the garment more than plastisol or water based inks it will means pressure settings, whether on an auto or manual, need to be approached accordingly.

Occasionally you even have to run them through the dryer twice if they are coming out a bit inconsistent. You may also need to add an extra 1-2% of agent sometimes to make it really pop."

we are starting to back out of printing discharge due to the current state of apparel.

Garment manufacturers are RACING to get goods out, and we are seeing corners cut left and right.

Discharge is not dependable anymore with all the factors outside of our control.

Agreed with Eric, we are still doing colors with discharge but white discharge is no longer a good product across ink manufacturers.

If you are printing lots of discharge inks you should do wash tests often and prolonged because we are having our white discharge fail after 1 wash, while other colors still look decent.

We instead do discharge base with white high solid acrylic on top, and still do some discharge colors when matching a Pantone isn't critical and the correct color.

Whatever changed in the ink manufacturers / supply chain they are being hush about it, but we've tried multiple inks and they all have subpar results, they look decent until washing, and this is in regards to shirts that discharge great.

ASColour is not one of those shirts that discharge great, they know it and point the finger at the printer, rather than dialing in their manufacture process to have better reactive dyes in my opinion.  It is a nice tee though :)  Anyone negotiate free freight with them?

that is good to know I will probably just go HSA for the black Ts instead of trying to make the discharge work. Recently had a client provide some of the off white AS organic long sleeves and they printed really nice so I got an account to try them out for a few projects
