I have a plate block of these and up close they just look like crap. There also seems to be printing errors. What causes each of these errors and how much do they devalue a stamp? There's missing ink, smeared ink, and overlapped ink. Overall they just look blurry.

Still wondering how that smear happens though.

The sawtooth edges of the images indicate to me that the printing was by gravure, so I suspect the smear was caused by an oversize ink particle that had been trapped under the doctor blade and came loose during the oscillation of the blade, that was then squashed by the impression roll. Probably restricted to the one stamp or to one rotation of the gravure cylinder.

My first guess would have been that the sawtooth edges along the bottom of the skis were an artifact of scanning & pixelation.

Donald, you are correct in that it is limited to a single stamp from my full plate block. Thanks for the input.
