Pantone matching
Pantone matching uses the Pantone Matching System (PMS) — a standardized numbered ink reference library created in 1963 — to specify and reproduce an exact spot color across different printers and materials.
Why it matters in a DAM
A DAM's brand-asset metadata commonly carries the PMS number and finish (coated, uncoated, matte) attached to a logo file, so any print partner anywhere in the world mixes the identical ink rather than eyeballing a match on an uncalibrated monitor or press. The current Pantone Formula Guide lists 2,390 market-driven spot colors across coated and uncoated stocks.
A worked example
Common mistake
Storing a brand's Pantone number in a general description field instead of a dedicated, searchable metadata field, so print vendors have to open the actual design file to find the color reference instead of reading it directly off the asset record.
The Pantone Matching System was created in 1963 by Lawrence Herbert, who built a standardized library of numbered ink formulas specifically to solve the problem of color matching drifting between print runs and printers. Each number in the system corresponds to a precise ink mixing formula that any print shop with a Pantone formula guide can reproduce identically, regardless of location or equipment — the current Pantone Formula Guide catalogs 2,390 spot colors across coated and uncoated paper stocks.
Because the system standardizes color across an entire supply chain, PMS numbers are the natural piece of metadata to attach to a brand’s logo or key visual assets inside a DAM. A single field carrying the exact number and finish — for example a coated versus uncoated variant of the same number, since ink can look different depending on the paper — lets any print partner anywhere reproduce the brand’s exact color without needing to open the original design file or rely on a monitor that may not be calibrated.
Where this breaks down in practice is when the Pantone reference exists only inside the design file’s swatch palette, invisible to anyone browsing the DAM’s asset library. A print vendor onboarding for the first time then has to either request the source file or guess, both of which introduce delay or risk to what should be a one-line lookup.
A complete Pantone reference on an asset record typically includes:
- The PMS number itself, e.g. PMS 186
- The finish suffix — C (coated), U (uncoated), or M (matte)
- Which print use the reference applies to, if the brand specifies different finishes for different materials
Frequently asked
What does the C, U, or M after a Pantone number mean?
It indicates the paper finish the color was formulated for — C for coated, U for uncoated, M for matte stock. The same Pantone number can look noticeably different depending on which finish it's specified for, since ink behaves differently on different paper surfaces.
How many colors are in the Pantone Matching System?
The core Pantone Matching System—the Pantone Graphics System sold as the Formula Guide for coated and uncoated stock—currently lists 2,390 spot colors, each assigned a unique PMS number and a documented ink formula for consistent printing. Pantone periodically expands the library, retiring and adding shades as market demand shifts, so the count creeps upward over time. Pantone's other product lines, covering fashion, plastics, and interiors, use separate numbering systems with their own color counts.
Who created the Pantone Matching System, and when?
Lawrence Herbert created the Pantone Matching System. Herbert bought the company—then a small commercial printer—in 1962, and drawing on his chemistry degree, he standardized its ink-mixing formulas into numbered swatches. He released the resulting fan-deck system in 1963, giving printers, designers, and manufacturers a shared numeric reference so a chosen shade could be reproduced identically across different presses, materials, and vendors worldwide.
Why does a DAM need to store the Pantone reference separately from the design file?
So the exact color can be looked up by anyone — a new print vendor, a licensee, an internal team — without needing access to or the software to open the original design file, speeding up onboarding and reducing the chance of a color mismatch.
Can a Pantone color be reliably matched using RGB or CMYK values instead?
Not exactly — RGB and CMYK are both approximations of a Pantone spot color's actual appearance, useful for on-screen or process-printed reference, but the true match comes from the physical ink formula, which is what a Pantone number specifies.
Does Pantone matching apply outside of print?
Yes — the Pantone system is also used across product design, packaging, plastics, textiles, and paint industries as a shared color reference, though the print-focused Formula Guide and coated/uncoated finishes are specific to the graphic arts side of the system.
