Different Samples Serve Different Purposes

Buyers reviewing custom product development should distinguish between production artwork, a prototype, an unpainted model, a color sample and the approved production reference. Each represents a different stage of the project and answers a different question.

Production Artwork and Prototypes

Production artwork is the technical design used to prepare tooling. A prototype or master model shows the three-dimensional form before finishing. Reviewing these early stages catches structural issues before investment in production tooling.

Unpainted Models and Color Samples

An unpainted model shows shape, relief and proportion without color. A color sample applies the intended painting, plating or enamel so you can judge the final look. Evaluating them separately makes it clear whether a change is about form or about finish.

The Approved Production Reference

The approved production reference is the standard that production and inspection are held against. Once this sample is signed off, changes should be treated as a scope change with cost and schedule implications, which keeps both sides aligned during mass production.
