As a dark, low-lightness shade, fingerprints, dust and handling scuffs show up more than they do on light colours. A matt or textured finish hides them better than high gloss, and gloss levels above about 70 units also make any substrate defect easier to see – agree the gloss level with your coater before the first batch.
