InDesign Certification Practice Exam

Process colors are created by mixing varying percentages of cyan, magenta, yellow, and black inks. This uses the subtractive color model used in printing, where each ink absorbs certain wavelengths of light and the combinations produce a wide range of colors on white paper. The black ink (K) is added to achieve deep shadows and accurate dark tones without needing excessive amounts of the other inks. Colors produced on screens rely on light (the RGB additive model), Pantone refers to premixed spot colors for exact matches, and gray is simply a neutral tone not representing the standard four-color printing process.
