Title: White ink left overs
Post by: 3Deep on June 03, 2014, 01:25:06 PM
Like most of you I've tried many different brands of white inks and now have samples, half gals, qts of white ink everywhere..... just thinking what would happen if I just mixed them all into one gal, I'm I asking for trouble?  Might mix some and test on my own shirts...

Part of me says don't do this however there might be some safe applications. Hi white for sim process for instance.

don't mix them, just use up the buckets.

If you are talking about scraping the bottoms, I would not.

Whats it going to hurt. If there is not enough of each one to use. They why not mix them up. I have done that with some whites in the past. Test them first before using them on customer shirts. Just don't mix any dried out inks. If they are good flowing inks mix them up and get them out of your way.

opacity, bleed and cure temp issues. If one cures at 275 and another at 320 you'll overcook the first one. Low bleed is another issue, it would be good for cotton only unless they are all lo bleed, and even then I would not trust them, so back to cotton only. And then the customer calls and wants a repeat and your white is blue tint on one shirt and yellowish color on the new order. . . for few bucks, it's not worth the headache.

I agree with everything that Pierre just said except the cure temp and everything else will be a average of the inks mixed. So if you mix a 275 cure with a 320 cure ink you get a 297.5 degree cure. So its not as big a deal as you may think. Now would I use this ink on a picky customer...no but I would a every day guy that needs what ink on black shirts.

One thing I have done in the past when I have ink I will never use or stuff like that, I have posted it for FREE here or on the other forum that has turned into DTG town ;D but I have said it is free, just send me your UPS number and it is all yours. I feel much better about that than just throwing stuff away.

We give it to the schools & hobby printers that we burn screens for.

been doing it for YEARS!  Use it as a high light white until its gone.  Never had a problem.  We are talking cotton shirts here.
