These are different exposures. Record the selected contact material and whether the test concerns a dyed substrate or a printed area. An airlaid napkin supplier should not substitute a convenient liquid for the agreed exposure without recording that change. Keep an unused contact material as a blank so contamination can be recognized.", "Use the same specimen dimensions and contact arrangement for the reference and candidate.

Conversely, a visible shade difference does not by itself demonstrate dye transfer. Keep separate records for appearance and staining. Compare the contact material after exposure, rather than judging only how much color seems to remain in the napkin.", "The published DIN listing for EN 646 concerns color fastness of dyed paper and board intended for food contact.
