Will my Pantone color look the same in CMYK?

Many will look close. Some, especially bright oranges, greens, blues and purples, and all metallics and fluorescents, can’t be matched with four inks. If an exact brand color matters, print it as a spot ink, which costs more on short runs.

What do the C and U after a Pantone number mean?

C is coated and U is uncoated: it’s the same ink, shown as it looks on each kind of paper. Pick the one that matches the paper you’re printing on.

How do I know if my job is CMYK or spot?

Your quote says. “4/4” or “full color” means CMYK on both sides; a job quoted with named PMS (Pantone) inks uses spot colors. If you’re not sure, ask before converting anything.

“Convert the spot colors to CMYK”: Converting Pantone and spot colors to CMYK

Short answer

A spot color, usually a Pantone swatch, tells the press to print that color with its own pre-mixed ink on an extra plate. If your job prints in CMYK only, every spot color has to be converted to CMYK first, or it can print in the wrong color, add an unwanted plate or go missing. If the job really does use a Pantone ink, the opposite applies: that color must stay a spot color, with exactly one name used everywhere.

Why printers ask for this

Most cards, flyers and menus print in four colors, CMYK. Logos from other designers, brand guidelines and Illustrator swatch libraries often bring spot colors (also spelled “spot colours”), usually Pantone swatches, along without anyone noticing. On a four-color job, the printer’s system then has to decide what to do with an ink that isn’t on the press: depending on the setup, it converts it automatically (not always to the color you expect), outputs an extra plate nobody will use, or leaves that part blank.

On jobs that do print a Pantone ink, which is common for labels, packaging and screen printing, the problem flips. The color must stay a spot swatch, and it must have one name. “PANTONE 186 C” in the logo and “PANTONE 186 CVC” in the layout are two different inks to a press, so the printer gets an extra plate, and you get a phone call.

How to convert or set up spot colors for print

Find them. In Acrobat Pro, All tools → Use print production → Output Preview (Tools → Print Production in older versions) lists every ink in the PDF; our free print-ready checker lists spot colors too. In Illustrator and InDesign, spot swatches carry a small spot-color icon in the Swatches panel.
CMYK job, Illustrator: double-click each spot swatch, set Color Type to Process Color and Color Mode to CMYK.
CMYK job, InDesign: Swatches panel menu → Ink Manager → tick All Spots to Process. It converts on export and leaves the swatches intact for a future spot run.
For the closest match, use Pantone’s own CMYK values (the Pantone Color Bridge guide) rather than the automatic conversion, and expect some bright oranges, greens and blues to shift: CMYK can’t reach them.
Spot job: keep the Pantone as a spot swatch, use the same name everywhere (InDesign’s Ink Manager can alias a duplicate to the right ink), and choose the C or U version to match the paper.
Canva doesn’t support spot colors. If the job needs a Pantone ink, the file has to be set up in Illustrator, InDesign or Affinity.

Other things printers say

The printer said“The file is RGB, it needs to be CMYK.”Screens make color from red, green and blue light (RGB); printing presses make it from cyan, magenta, yellow and black ink (CMYK).See the fix The printer said“There’s no white ink layer.”Printing inks are see-through and CMYK has no white, so on clear film, metallic, kraft or dark stock, colors look faint and anything meant to be white simply isn’t printed.See the fix The printer said“The transparency needs flattening.”Drop shadows, glows, opacity and blending modes are “live transparency”, which some printers’ systems can’t process reliably.See the fix
