Spot color是什麼意思

"Spot color" is a term used in printing and graphic design to refer to a specific ink color that is mixed and applied to a printing press separately from the standard CMYK process colors (cyan, magenta, yellow, and black). Spot colors are typically pre-mixed inks that are applied directly to the printing substrate without being created through the combination of CMYK inks.

Spot colors are often used for branding purposes, as they can accurately reproduce a specific hue that cannot be matched by the CMYK process alone. They are also used for Pantone colors, which are a standard set of colors used in the printing industry for color matching.

When a design calls for a spot color, the printer will use a separate ink plate to apply the ink, in addition to the CMYK plates. This allows for a wider range of colors to be reproduced, and can result in a more vibrant and accurate color match.

Spot colors are often used in packaging, marketing materials, and other applications where a consistent and specific color is important. They can also be used to create special effects, such as metallic or fluorescent inks, that are not possible with the CMYK process alone.
