    In gravure, flexography, and screen printing, the result of pinholing. See Pinholing.

    In photography, pinholes are small, transparent dots that appear in non-image areas of a negative (or small black dots that appear in the non-image areas of a positive) produced by dust on the camera lens, copy, copyboard, or film. Pinholes also appear in non-image areas of photostencils.

    In papermaking, pinholes are small imperfections in the surface of a paper, produced by foreign particle contamination during forming.
