How To: Pantone Mixing [feedly]

How To: Pantone Mixing
// Ryonet's Screen Printing Blog

Factors to consider:

Customer Requirement of Color Accuracy:
1. Is it a trademarked color?
2. Color of the garment?
3. To Under base or not under base?

Mixing inks is, in itself, an art form. Different mixing systems have different formulas and those differ from Pantone's suggestions as well. Even the most thought out mixing system will have to be tweaked to fit one's specific needs. Below are the steps on how to start mixing custom inks and Pantone's:

1. First, you start by determining if your client wants a specific PMS number, or a color "close enough". Close enough will allow you the latitude to steer your customer to standard ink colors you may already have on your shelf. This saves you both time and money. If there is a specific PMS color the customer is wanting, the next question is if it is a trademarked color. If it is, your diligence in mixing it will be key. I will cover this a little later. If it is not, you can advise the customer you will mix the color to as close as you can to the solid pantone book. It is important to get a customer proof signature, especially with PMS color matching. This way you cover all your bases and the customer cannot recant due to a color shift on press.

2. Next, determine the color of the garment. The color of the garment will alter how one sees the colors that are placed on top of it. See Color Theory. Our perception of color, in relationship to adjacent colors, can radically shift the color mixed even though the ink has not changed at all. When mixing a specific PMS number it is critical to consider the context in which it will be printed in. ie the shirt color.

PMS colors that are mixed to match the swatches in the Pantone Solid Coated book are actually being matched for printing onto a white garment. This is because the book itself is printed onto white paper. When printing on white this should be fine, but printing onto colors it becomes a little more work to match that color. If you under base with white, then you are fine with a standard, or formula mix, as it will keep the color integrity.

However, going onto a colored shirt directly you may need to alter the formula in order to get the color to visually match the color called out. This is where it is important to clarify with your customer as to the requirement of matching the color exactly. For example, NIKE uses PMS 1655 Orange as NIKE Orange. It is required the color "look" like PMS 1655 regardless of substrate. In a shop I used to work at we had 20 different buckets of ink called PMS 1665 NIKE. Each one mixed to a specific substrate, everything from a brown wood box to a navy blue t-shirt. The background color alters the perception of the orange requiring us to tweak the color we are mixing so the printed color matches 1655 exactly. This can be a daunting task if not approached correctly.

The key is to Test, test, test. Most printers either mix by eye or with a mixing system. A few will have manufacturers or suppliers mix the inks for them. Although this saves you time it can be costly and if you are printing on anything other than white, the color may be off on the final product. When mixing, it is best to start by mixing the color to match your Pantone book. This will give you a solid base to begin with. Then, print and dry the ink on the shirt color you will actually be using. This will tell you which direction to go to match the color visually- Tweak the color and test again. This process can take a while but save you uncomfortable explanations of color theory with the customer after the fact.

Color Mixing: The Importance of Using a Color Chart

By Birgit O'Connor

A systematic way to test color combinations before mixing them on your paper is to make a color chart (I've provided a link to a template for a blank color-mixing chart here; use it to test your color combinations). By creating color charts, you can teach yourself basic color theory. Better still, when you're in the midst of a painting and encounter a problem, you can consult a color chart to help you decide what to do.

Imagine that you're painting the stem of a flower and that, just under the flower, the color shifts. If you've got a color chart to consult, you'll have a good idea how to match that change in color. If you're painting a landscape, you don't want the grass to be one, unvaried green because the effect would be flat and uninteresting. You want to create variety in your greens, and consulting your color chart will inform you of choices you may not have thought of on your own: for instance, violet mixed with Hooker's green or indigo mixed with raw sienna.

To make your color chart, use a half or quarter sheet of watercolor paper so you can post the completed chart in your studio. If you're working in a cramped space, use 8½x11 sheets and keep them in a folder. Start by making a grid of 1- or ½-inch squares. You'll want to be able to paint at least 8 to 10 squares of color, with grid lines between them, along the top and down the side of the paper.
