What is the role of color conversion in prepress?

• A. Converting document colors from RGB to CMYK to match print press.
• B. Increasing resolution to 300 DPI.
• C. Applying gradients to backgrounds.
• D. Flattening layers to reduce file size.

Answer: (A)

Color conversion in prepress is about translating colors from RGB, the color space used for screens, into CMYK, the color space used by most printing presses. Since RGB is based on light and CMYK on ink, they don’t share the same gamut, so not every RGB color can be reproduced exactly in CMYK. Using color management tools and ICC profiles helps predict how colors will print and guides adjustments so important elements like skin tones, logos, and gradients stay as true as possible after the shift from display to print. Soft proofing with calibrated devices lets you see the expected result before pressing, and the conversion may involve tweaking saturation, brightness, or individual colors to maintain consistency across different inks and paper stocks.

Other tasks mentioned—raising resolution, applying gradients, or flattening layers—deal with image sharpness, design effects, and file handling, not the color space conversion that's essential for accurate print reproduction.
