Use these points to control the next decision.
- The same ink target can appear different across white, colored, kraft, textured, laminated, or metallic surfaces.
- Approve color on a process-relevant substrate and record the viewing condition.
- Separate brand-color direction from the production acceptance method.
Start with the substrate
Paper color, texture, coating, absorbency and opacity influence the visible result. A color approved on a bright coated sheet should not be assumed to match on uncoated kraft, colored paper or a wrapped rigid-box surface.
Record the material name or agreed reference, surface treatment, print side, backing condition and whether the production material can vary by lot.
- Material and surface reference
- White, colored, kraft or metallic base
- Coated, uncoated, laminated or textured surface
- Print side and backing condition
Define the reference hierarchy
Identify whether the controlling reference is a physical color standard, approved drawdown, press proof, signed sample or instrument reading. Screens and office printers are useful for content review but should not become the only production color reference.
If several references exist, state which one controls and how conflicts will be resolved. Keep the approved reference protected, labelled and linked to the artwork revision.
Review process and finish interaction
Spot color, process color, white ink, varnish, lamination, foil and embossing can change perceived hue, density and contrast. Transparent coatings and films can shift appearance even when the underlying print remains unchanged.
Approve critical combinations rather than each element in isolation, especially where a printed color sits next to foil, on a dark substrate, or beneath a film.
| Variable | Possible effect | Approval action |
|---|---|---|
| Paper base | Changes brightness and undertone | Approve on proposed substrate |
| Lamination | Changes gloss, depth and contrast | Review after final film |
| Metallic surface | Reflectance changes with angle | Use agreed viewing positions |
| Texture | Ink and light vary across relief | Review representative area |
| Production process | Differs from digital simulation | Use process-relevant proof |
Record acceptance and escalation
Define critical colors, reference method, viewing condition, measurement location where applicable, sample size, decision owner and escalation path. Avoid applying one generic tolerance to every substrate and finish.
When the production material or process changes, document whether the original approval remains valid or a new proof is required.
