Title: Polyester Black Tees
Post by: Logoman on February 13, 2017, 04:13:39 PM
I am printing 1000 Black Polyester Tees and need to print White and Red Print. What would be the bets to use on this. I have had problems with printing white on poly. Is there a ink that I would not have a problem with Bleeding regardless of Temp.?

Wilflex Top Score and WM Plastics Titan have been the home-run Poly Whites for us.

I'd say that if this is taken too literally, it could be a deal breaker. These poly inks tend to have a cure temp of 300 or below, and I'm pretty sure that is a factor in their bleed resistance.

Is there a higher Temp Poly Ink?

Define Higher Temp?

If you can go low temp for your cure.  Get the one stroke ELT-S series.

The real kicker - completely depends on the quality of the polyester in your shirts........

I have an old National Gas Dryer and it does not do well with Polyester Tees. I have 1000 to print 2/1. Trying to make sure the Poly. does not bleed through

You can mix in a touch of low cure additive into your highlight colors to help them cure at a lower temp as well.  Most poly inks like Onestroke do cure at a lower temp.

Once again where I love the Sport Tek PosCharge. Really shoes that poly dye does not have to be the issue it can be if apparel manufacturers thought about decoration down the line.

A lot of folks here disagree with me but we print a barrier base thru a 160 as the base then colors and you can run a decent LB white( wee use epic quick). The hand is excellent and I can honestly say we have not had a bleed problem.

And, this does fine at temps above 320 for Logoman?

I have a old National dryer, and I use Rutland white streetfighter with a low temp additive.  I make the shirt hit 315-320 degrees on the gun and I don't have a bleed or cure problem.  Just got done with Badger royal digital camo and Hanes 4820 in royal.

This seems remarkable as camo generally needs the big guns rather than a $40 low bleed!

Use Sanmar's tees with posicharge. I've run them through at 375 with cotton white an no issues and the print is much softer.

Second option is silicone ink but it really sucks to flash.

We just printed 3000 Black 100% Polyester tees. Used the Wilflex Epic Undrebase Grey which is a Carbon Blocker.

Then 2 Polywhites on top. Worked very well. Not sure we made a lot of $ because the Grey is super expensive.

Would never have tackled that job until we discovered this ink which works miracles.

When we stripped the machine the emulsion on the screens was stained black. Bad dye, bad fabric, white prints.

You are right on the camo.  I did get a little bleed.  Although it was acceptable to the customer.
