In the 'Mebes' bromoil bible I only found one description of regular black
spots: brush hairs (stiff brush or too heavy brush movements)
piercing the gelatine with the effect of small black-ink- spots.
The growing would be due to the fact that the water is
expanding beneath the gelatine and/or the ink is filling up the wholes.
But he is only referring to s m a l l spots. Hope this helps.
