Where to get your formula

A formula is a recipe for an ink color. It lists which inks to mix and how much of each one. This calculator has no color recipes in it. (PMS/Pantone-style color references are numbered standard colors, like "PMS 186 C".) You get the recipe from the company that made your ink.

Each recipe only works with that company's own mixing inks. So use the site that matches the brand on your ink buckets:

Example formula (made-up numbers for practice)

These numbers are made up. They are not a real Pantone recipe. Say your recipe says:

  • Mixing White: 12 parts
  • Yellow: 3 parts
  • Red: 1 part

"Parts" just means shares. 12 parts white means 12 times as much white as red. Here there are 16 parts in all.

A batch is the total amount of ink you mix at one time. Say you want about a quart. This tool works by weight, not by volume, so there is no quart setting. Many ink makers write recipes for a 1,000 gram batch. That is roughly a quart of ink, but the exact amount depends on the ink.

  1. Leave Formula is in on Parts / ratio.
  2. Type each ink name and its parts (12, 3, 1) in the rows.
  3. Set Batch size to 1000 and Unit to g (grams).
  4. The table shows: Mixing White 750.0 g, Yellow 187.5 g, Red 62.5 g. That adds up to 1000 g.

Does your scale read in ounces? Pick oz and type 35.27. That is the same as 1,000 g. If your recipe uses percents, pick Percent. If they don't add up to 100, the tool fixes that for you.

Tips: Put the empty cup on the scale and press zero first. Add dark colors last, a little at a time. Print a test and heat it fully (this is called curing) before you compare it with the color reference.

Mixing tips

  • Weigh ink on a gram scale. Don't measure it with cups or spoons.
  • Mix well. Print a test on the same kind of shirt, then heat it fully (cure it) before you compare it with the color reference.
  • The printed color can change with the shirt color, the screen, how much ink goes down, and whether you print a white layer under it first.

What each box means

New to screen printing? Here is what every box above asks for, where to find the number, and a typical example. Tap any next to a box to jump to its explanation.

Color name
The name of the color you are mixing, like PMS 186 C. Pantone (PMS) is a numbered color system shops use so everyone means the same color. This name is just a label on your ticket.
Formula is in
How your ink maker's recipe is written: as parts (like 3 to 1), as percents, or as weights. Match what the recipe shows.
Components
One row for each ink in the recipe. Type the name from the recipe, like "Base Red", and its amount. Use "+ Component" for more rows and × to remove one.
Batch size
How much finished ink you want to make in total, for example 1000 (with grams as the unit, that is 1 kilogram). The tool scales the recipe to this amount.
Unit
The unit for the batch size: grams, kilograms, ounces or pounds. Grams on a kitchen-style scale are the most accurate.
