foil transfer

[noortrd]

In four color two color matsui 301 and two color foil transfer. Whrn we transfer the foil the foil also adher on matsui 301 . Any procedure that foil not transfer to unwanted area?

We do a pretty decent amount of foil and use 301 and discharge from matsui often with it.  We haven't ever had it stick...

What kind of ink deposit are you putting on the shirt (thickness, depth pushed into the fabric)?
Are you curing the shirt prior to pressing? (you should be...)

Try shortening your press time.

You want to say we mix 301 white and discharge ?. We dryer and than press foil.

I'm not sure you're understanding my comment.  I am not saying to mix anything, just that both 301 and discharge act the same on the shirt as they are both waterbased inks.  Once you send a shirt printed with either type of ink through the dryer, the foil will not stick to it.  This allows you to print the foil adhesive with waterbased on more intricate designs and the foil will only stick to the foil adhesive.  We do this all the time without issue.

matsui white  301 contain acrylic binder and they stick to foil.

Shrug.  We have printed Matsui 301 with foil without it sticking as long as the shirt is cured properly prior to heat pressing them.  Not sure what the issue could be in your production steps.

Sir when he heat transfer to foil the white 301 also hot and soft and stick to foil.

I have noticed, that if the waterbase ink deposit is fairly thick, it can sometimes grab onto the foil a little bit.

How thick is the ink deposit where the foil is sticking?

Does it stick to every waterbase ink color?

[noortrd]

yes but not on discharge.

[Colin]

Then it sounds like the simple solution is to discharge the ink colors you do not want the foil to stick too?

It is not a perfect solution, but if it works

[noortrd]

But our fabrics is poly/cotton blend. Discharge not possible

[Colin]

I know it will not change the final print color, but, if adding the discharge agent makes the foil Not adhere to the ink.  Then that sounds like a solution to the problem.

I can't image how thick your ink deposit must be to allow it to "gum up" when pressed after being properly cured.  How are you curing (temp/dwell time)?  Have you wash tested the print prior to pressing with foil to ensure it is properly cured? What emulsion and coating/drying method are you using?  How many strokes and what squeegee pressure/angle?  How hot is the press and what amount of pressure are you using?

I'm not lying when I say we have used the 301 white without issue when using foil.  We coat 1/1 on a 160 as our standard when using waterbased inks, and for 301 white on a polycotton (not something I would normally do since it isn't optimal for opacity and durability) we would use a low angle with a slow, hard stroke using a triple durometer squeegee.  The majority of the ink is mashed into the fibers of the shirt.

We've been printing discharge white (Rutland and CCI) with foil for years and never had any issues.

And then a couple weeks ago we started to get a little bit of transfer to the white on a job re run
all the time. (Rutland)


Chalking it up to an off batch as nothing else had changed.
