- Reference identity
- Brand color name ___; reference system/code ___; coated or uncoated reference where relevant ___; physical reference ID and condition ___; reference owner ___. Record whether the printer will work from a commercial guide, a retained print or another agreed target. Do not let a photo of an old guide silently become the contractual color reference.
- Production surface
- Box or film specification ___; surface color ___; finish/coating ___; opaque or transparent construction ___; backing or filled-pack condition ___; proposed print process ___. Ask the printer which reference and proof route represent that construction. If a white underlayer is proposed on film, identify it as part of the print arrangement rather than an incidental layout detail.
- Comparison conditions
- Viewing arrangement ___; light source ___; background ___; reference/sample orientation ___; reviewer ___; comparison date ___. Keep the reference and sample in the same comparison conditions. State separately any additional shelf or use-environment check so a commercial appearance preference is not confused with a controlled approval observation.
- Measurement agreement
- Instrument and provider if used ___; measurement settings ___; agreed color-difference calculation ___; target and tolerance agreed by parties ___; reading locations ___; report reference ___. Ask the provider to define a compatible measurement setup. No universal color-difference limit is supplied here; a number without its calculation and conditions is an incomplete requirement.
- Physical release
- Printed sample ID ___; artwork revision ___; material revision ___; visual decision ___; instrumental decision if commissioned ___; unresolved concern ___; release authority/date ___. Attach the accepted physical sample or its controlled storage reference. Record whether approval covers a proof, a trial print or the proposed production construction.
