CMYK process printing builds color from cyan, magenta, yellow, and black. A spot color uses a separately specified ink or plate. Choose the workflow from the artwork, color tolerance, substrate, finishing plan, press method, proof route, quantity, and budget rather than from the number of colors alone.
Use CMYK for broad image reproduction
- Photographs, gradients, illustrations, and artwork with many colors.
- Projects where a controlled process-color proof is an acceptable approval reference.
- Components that need one consistent profile and separation workflow across complex artwork.
Use spot colors for defined production needs
- A brand color or graphic element needs a separately specified ink.
- The desired color sits outside the practical process-color result on the chosen material.
- A varnish, coating, white ink, metallic ink, or other production layer needs its own plate.
- Simple limited-color artwork makes a spot workflow practical for the selected press and quantity.
Adobe explains that process color combines the four CMYK inks, while a spot color uses a separate premixed ink and plate. It also recommends previewing separations and working with the commercial printer on ink, overprint, and proof settings.
Control the file and proof
- Name spot swatches consistently and remove accidental duplicates.
- Confirm whether a spot color stays separate or converts to process.
- Check overprint, transparency, rich black, small reversed text, and finishing separations.
- Approve against the stated material, coating, light, and proof limitation.
- Record acceptable variation and the reference used for mass-production approval.
What to send for color review
Send the print PDFs, source files when requested, named color references, substrate, finish layers, proof expectation, quantity, and any existing approved sample. Jinayon can confirm the proposed print workflow and flag color decisions that need a physical sample.
