Describe when the mark appeared: unpacking, dispensing, handling or another known step. Keep uncertain observations separate from confirmed facts; a colored mark alone does not identify its cause.", "The review should distinguish loss of printed color, visible transfer to a contacting material, loose fibers and tearing. These can coexist, but they lead to different questions. Record what is visible before suggesting an ink change. A change that reduces one symptom may not address the original handling problem.", "Preserve the affected pack and a protected reference from the same lot where possible.

Its stated applications concern graphics on flat substrates such as packaging materials.

If the specimen wrinkles, slips or tears before a meaningful print comparison is possible, ask whether the setup answers the procurement question. Document any adaptation and describe the resulting test accurately.", "The ASTM reference is a starting point for discussing controlled comparison, not a universal napkin pass limit.

The approved physical sample should represent the printed material and finish being purchased. If that sample is only an appearance reference, say so; do not silently treat it as evidence of durability.", "For food-contact use, assign the relevant compliance review separately and identify the destination and intended contact conditions.

Record whether ink, substrate, print coverage, drying or another identified production parameter changed; do not claim a root cause until the investigation supports it.", "The final approval should identify the sample, artwork revision, method and acceptance basis.
