Process color uses translucent CMYK inks laid on top of one another to fool your eye into seeing other colors. A spot color ink is a specially-mixed hue that is not made by combining two or more inks, but rather is a single ink of a specific color. Spot colors can be brighter or more saturated than process colors, or have special properties, such as metallic gold or fluorescent green. Train Records uses process colors in printing packaging, and either CMYK or spot colors when printing on-disc. Spot colors are available for print package printing for an additional fee.
