A screen concept explores direction
A rendered image can help discuss graphics, form and visual hierarchy. It cannot establish board stiffness, dimensional fit, ink color, foil behavior or the final surface feel. Treat it as a conversation starter.
A structure sample tests the fit
A plain structural sample can check product fit, closure, insert support and the assembly route. Supply representative product dimensions and weight. Ask which aspects the proposed sample will establish and which remain open.
A printed sample reviews the construction
A printed sample can review how graphics and finishes behave on the intended material. Confirm whether it uses the final print route and stock; a digital proof and a production sample answer different questions. Scope, cost and timing belong in the quotation.
Make approval specific
Record the approved artwork version, structure, material, finishes and agreed inspection criteria. Any change after approval should be reviewed for its effect on cost, timing and the sample reference.
