Is an RFU Mixing System Right for Me?  |

There are two main mixing systems you’ll find in a screen printer’s shop: Ready For Use (RFU) and Pigment Concentrates (PC)

Pigment Concentrates
What most screen printers think of when it comes to Pantone® matching is a mixing base with a variety of pigments that are mixed to create their desired color profile. These systems are highly effective and come with a few pros and cons, depending on how you plan to use them. PCs tend to be:

More customizeable

      – having control over the base you use is huge in shops that do a lot of athletic printing or specialty printing. PC mixing systems allow you to control nearly every variable of the ink you’re mixing, all the way down to its curing properties and finished luster


      – with all of that customization comes a smaller window of error. If you’re looking to achieve a specific color, even a slight overpour of pigment can cause a wave of difference in your final profile. This is why it’s always best to mix a small amount first, recording your changes, then mixing down what you need for your job.

An inventory consideration

      – one major attribute of PCs that will affect some shops more than others, are their tendency to keep a few excess pigments around that you just never use. Sure you got ONE order where your customer


      have that perfect red-orange


    , but you haven’t used the Rubine Red pigment needed for it since. Most pigments out there last a long time, but this can be seen as wasteful or over-prepared for some, more rigorous screen printers.

Ready For Use
Ready for use systems have “EFFICIENCY” stamped all over them. They utilize mono-pigment components that are printable when combined, or on their own – no base needed. With an RFU system you can expect:

More grace when mixing

      – Since you don’t have such highly concentrated pigments, you can go a little over or under when adding colors, and still come out accurate.

To stock less

      – Since you don’t need to keep bases around, and your pigments can be printed on their own, you are left with much more lean and usable inventory on your ink shelves.

A similar cost

    – There is very little variance in cost when considering these two styles of color matching, but with the added usability of every pigment in the RFU category, you can make all your pennies count.
