Extend as in add base to it to get more out of a bucket, while affecting opacity slightly?

you can get top score base... we have a gallon here that we use when we're mixing top score colors (mostly tho we use performance base)

Thanks, Another question can you print top base color and print reg plastisol on top, or will you have adhesion problems?
I am thinking problems, correct? Because of temp differences.
Thanks,
Shane

I have never had problems doing so but you negate the benefit of the low cure temp of the top score as you need to cure the top colors normally. But I have yet to have that be a problem. 350 degrees and you should be good, emphasis on should

For Wilflex Top Score (with a 290F) cure, I would consider using the Epic 10005PFX Epic Stretch Base as an extender if needed as it cures at 300F and gives additional stretch properties.  Link - http://www.polyone.com/en-us/about/businessgroups/Inks/Literature/10005PFX%20Epic%20Stretch%20Base.pdf (http://www.polyone.com/en-us/about/businessgroups/Inks/Literature/10005PFX%20Epic%20Stretch%20Base.pdf)  Understand that anything you add will decrease the properties of the ink - opacity, dye migration resistance, etc.  But, if you are printing on poly garments that are light colored and not prone to bleed, then this is a-ok.

You should have no problem with inter-coat adhesion between regular Epic colors and Top Score.  BUT, the cure temperature does need to be high enough to cure the colors (320f) in order to be fulyl cured and wash fast.

The low cure temp is important for working on poly garments - keeping temp below the polyester dye sublimation point.  That is why Top Score products were designed to cure at 290F.

Sometimes when i print manually, i will take curable reducer and add some LCA to it and then mix it together with top score white. Always small amounts. It is always to thick out of the bucket to print manually. Never need to reduce on the auto.
