Color checking is the process of verifying that colors in printed materials or digital designs match the intended specifications. This is crucial in industries like printing, fashion, and graphic design, where accurate color representation is essential for brand consistency and product quality. To perform color checking, professionals often use tools like colorimeters or spectrophotometers, which measure color values and compare them to standard references. This ensures that the final output aligns with the desired Pantone colors or CMYK values, helping to avoid costly mistakes and ensuring customer satisfaction.
