How should RGB images be handled in a document destined for CMYK print during preflight?

• A. Convert to target CMYK color space with a defined ICC profile or ensure proper conversion settings and embed color profiles.
• B. Leave RGB as-is and hope printer handles it
• C. Convert only if images are grayscale
• D. Ignore color management entirely

Answer: (A)

RGB images sit in a color space that isn’t the same as CMYK, so for consistent print results you should convert them to the target CMYK space using a defined ICC profile, or at least ensure the conversion settings are clear and the color profile is embedded. This ensures the color management system (the RIP or printer) maps colors from RGB to the exact CMYK values you intend. Embedding the profile travels with the file so the output device knows how to interpret the colors, reducing guesswork and preventing surprises like unexpected shifts in hue, saturation, or brightness. Relying on the printer to handle RGB conversion automatically can lead to unpredictable results, because different printers, drivers, or workflows may apply different interpretations of RGB data. That variability is what preflight aims to prevent. By converting to CMYK with a defined profile and embedding that profile, you establish a controlled, repeatable path from your document to the printed sheet. If there are colors outside the CMYK gamut, you can manage them during conversion (with the chosen rendering intent) and soft-proof to verify how they’ll appear in print.
