RGB vs CMYK and why prints shift

Why screen colors do not match print and how to set up files for predictable results.

RGB describes light-based color; CMYK describes a common process-ink color model. Print workflows may accept color-managed RGB, CMYK or spot colors. The right setup depends on the output process and profile, not a universal requirement to convert every file yourself.

Why colors shift

Monitors emit light, while most printed pieces reflect it from a material. Their color ranges differ, and paper color, coating and lighting affect the result. Some vivid screen colors are outside the range of a chosen print process.

Setting up for print

Ask for the required export settings and color profile. If CMYK is requested, convert using the agreed destination profile and preserve an editable original. Do not repeatedly convert between profiles or assume generic CMYK values match every press and stock.

Before you send the file

  • Confirm whether the workflow expects tagged RGB, CMYK or defined spot colors.
  • Share brand color references and any physical sample that must be matched.
  • Review a soft proof or printed sample if color is critical.

Common mistake

Assuming a screen preview is an exact print match can lead to disappointment, even if the file is CMYK. Discuss important colors and proof options before approving production.

Technical references

Manufacturer references explain the technology, not our current equipment or stock. Confirm the process and file requirements for your specific order.
