I assume you're using the Epic PC system?

The Wilflex IMS will give you a minimum and maximum amount of base so that you don't have curing problems.

I pulled up 801 for example:

1000g mix:
897.00   base                89.7%
97.6       electron blue   9.76%
2.90       extra white       .29%
2.50       electron yellow .25%

however, according to the mixing software, the minimum base is only 253.2g

if I was to use 253.2 as my minimum base, and did a bit of math...  that would make 356.2g of ink...  which would make the pigment load something like 29%

I guess i'm not paying enough attention...thank you ,

Jvanick is correct.  Check out the attached pic to see the difference.

Understand though -- opacity in plastisol is primarily gained through STRONG pigment loading.  That is white, yellow, blue-shade green, etc.  Increasing the level of highly saturated pigments - clean, but weak - like reflex blue (marine) or flou's really do not increase opacity.  So in this example, the white percentage is still less than 1% of the total (although darn near tripled from original).

Wilflex ready for use Super Flou's are built differently at the plant.  They do not use the standard Epic Mixing Base, but rather a base that is special to their flou formulations.  This base is not available for sale - if I recall, it can only be processed on the specialized equipment at the factory.

Here is a perfect example of a formula that can be modified that would have a huge impact on opacity.  Decreasing the base to the minimum results in tripling of the pigment load, and the white is 34% of the total formula.

Personally, this is a bit of overkill.  I would probably adjust the base level to about 70%.

In support of Rob:

There is SOOOOOO much more an ink company can do for the opacity of an ink, when it is manufactured at the factory.

If you have the opportunity, Definitely buy the factory bucket.

and fyi..... there are distributors out there - selling Wilflex - who want to sell you stock colors made from the mixing system..... It is not the same....
