The sample should have a minimum size of 22 x 22 cm (or 3 patterns a 11 cm x 11 cm for a multiple determination), and have sufficient ink coverage.
Furthermore, the samples should be wrapped in aluminum foil immediately after its creation. Do not bent and / or crumple the samples .

We recommend (if possible) to send the empty original container to which the label will be applied.
