Direct answer: Kraft paper is not a neutral white background, so the substrate becomes part of the final color result.

Start with the intended kraft appearance
Natural kraft and other paper selections can differ in shade and surface. Confirm the approved substrate before treating a digital screen or white-paper sample as a color reference.
Adapt artwork to the substrate
- Expect transparent inks to interact with the paper color.
- Use deliberate contrast for small text and fine lines.
- Identify any area that is expected to appear opaque or bright.
- Review barcodes and regulatory information at final size.
Define the proofing question
State whether a proof is being used to approve layout, content, approximate color or the actual substrate appearance. Different proofing methods answer different questions.
Information to send the manufacturer
Provide the box or bag format, finished size, intended kraft look, artwork, quantity, finishing requirements and packing method. Ask the manufacturer to identify any assumption before quotation.
Common RFQ mistake
Avoid asking the supplier to assume missing dimensions, materials, quantities or pack definitions. Separate confirmed requirements from questions that need engineering input.
