Spot Color Ink Mixing Calculator

Spot Color Ink Mixing Calculator

Mixing a custom spot color? This calculator converts your target mixing ratio into precise gram weights for each component.

Each Component = Total Ink Needed x (Component Percentage / 100)

Example

500g total ink needed, mixed 70% base color / 30% mixing color:

Base Color: 350.0g, Mixing Color: 150.0g

Why Mixing by Weight Beats Mixing by Volume

Ink density varies between different colors and formulations, so measuring components by weight on a scale gives far more precise, repeatable results than estimating volume by eye - this is exactly why professional print shops weigh ink components rather than pouring by visual judgment.

Keep Records for Repeat Jobs

Recording the exact gram weights used for a successful custom color match makes it far easier to reproduce that identical color accurately on a future reprint or larger production run, rather than re-mixing from scratch by trial and error.
