Purpose
Spot colors let you name a brand color once and reproduce it consistently — without bundling a licensed Pantone library. This guide shows how to define named spot colors in Label Studio Creator, set their CMYK (and optional Lab) fallback, output them as separations or convert to process, and keep brand color stable across short runs.
The goal: a repeatable “Brand Blue” that behaves predictably in print and RIP, whatever the printer.
1. Why named spot colors
A spot color is a name plus a recipe. That indirection is what makes it powerful:
- Change the recipe once and every object using the name updates.
- Output as its own separation for spot inks or a RIP, or convert to CMYK for process printing.
- Keep brand color identical across jobs and operators.
- Avoid shipping a licensed Pantone book — define your own approved set.
2. Define a spot color
Create a named swatch
In the color/swatch panel, add a new color, mark it as spot, and give it a clear name (e.g. Brand Blue).
Set the CMYK fallback
Enter the process recipe used when the color is converted or printed on a CMYK device.
Add Lab if you measure it
If you have a measured Lab value, store it so a color-managed RIP can target it more accurately.
Reuse the swatch
Apply the named swatch to objects — never re-enter raw CMYK for the same brand color.
3. Fallback: how spot becomes process
| Situation | What happens |
|---|---|
| Process (CMYK) print | The spot is converted to its CMYK fallback recipe. |
| Spot separation / RIP | The spot stays on its own named plate for a spot ink or RIP handling. |
| Lab-aware RIP | A color-managed RIP can aim at the Lab target within the device gamut. |
| Out-of-gamut color | Vivid brand colors may not be reachable in CMYK — expect a duller fallback and proof it. |
4. Output & separations
Decide per job whether the spot travels as a plate or is flattened to CMYK:
- Use separation preview to confirm which plates exist (C, M, Y, K, + each spot).
- Export a RIP package when spot plates, white, or ICC metadata must be explicit.
- Convert to CMYK for a plain process driver that has no spot concept.
- Keep spot names consistent so downstream RIP mapping is unambiguous.
5. Keep brand color consistent
Approve once
Agree the CMYK (and Lab) recipe against a printed reference, then lock the swatch.
Share the swatch set
Distribute the named spot colors with your templates so everyone uses the same recipe.
Proof on real media
Color shifts with substrate and profile; proof brand colors on the actual stock.
Re-check after profile changes
New ICC profile or printer? Re-proof the brand colors before production.
6. Common problems and fixes
| Symptom | Likely cause & fix |
|---|---|
| Brand color looks dull in process | Out-of-gamut / weak fallback. Tune the CMYK recipe; accept gamut limits. |
| Extra unexpected plate | Stray spot swatch. Consolidate to the approved named color. |
| Color differs between jobs | Raw CMYK re-entered. Always apply the shared named swatch. |
| RIP ignores the spot | Name mismatch. Align swatch names with the RIP's spot mapping. |
| Shift on new material | No re-proof. Re-proof brand colors on the new substrate/profile. |
