Direct answer: CMYK and Pantone are not interchangeable promises; each is a way to define and control a different kind of color requirement.

When CMYK is appropriate
Process color is commonly used for photographs, illustrations and artwork containing many colors. Results still depend on substrate, ink, press conditions and finishing.
When a spot-color reference helps
A named spot color can clarify a critical brand color or a solid area that needs a defined target. The buyer should state the reference system and whether a physical swatch is available.
Factors that change appearance
- White, coated, uncoated or kraft substrate
- Gloss or matte surface treatment
- Metallic or transparent effects
- Viewing light and surrounding colors
What to approve
Agree on the reference, proofing method and acceptable review conditions before production. Do not use an uncalibrated screen as the only acceptance reference for a critical printed color.
Common RFQ mistake
Avoid asking the supplier to assume missing dimensions, materials, quantities or pack definitions. Separate confirmed requirements from questions that need engineering input.
