Calculating Ink Blend Formulas
Enter the name of each base color or additive in your formula into the fields in the Base Color column below. You can use any name or format you like, including numbers, symbols or custom color names.
Enter the weight of each base color in your formula in the Weight column, next to the corresponding base color name.
Click the Calculate button.
The blend formula will be displayed in ratios, in the Ratios column. If you prefer percentages, simply multiply each ratio by 100.
Using a Ratio Formula to Blend Ink
Determine the total weight of the color you want to blend.
Multiply this weight by the calculated ratio of each base color or additive. If you have your formula in percentages, you’ll need to convert to ratios first by dividing each percent value by 100.
Blend the indicated amounts of base colors and additives.
Example: Let’s say you are blending a color and you use 5 lbs. of Red and 4 lbs. of Blue. The units can be anything you want to use, pounds, ounces, grams, etc.
In the calculator at left, you will enter Red and Blue in the Base Colors column and 5 and 4, respectively, in the Weight column. Clicking the Calculate button will give you ratios of 0.666 and 0.333. This is your formula.
Now, let’s say you want to blend 17 pounds of this color from scratch. Here’s how you would determine the amount of Red and Blue to mix together:
17 lbs. multiplied by 0.666 = 11.322 lbs. of Red
17 lbs. multiplied by 0.333 = 5.661 lbs. of Blue
Theoretically, ratios should add up to 1.000, or percentages to 100.0. However, slight discrepancies are possible due to rounding issues. You may disregard these minute variations.
