Plate 71

Note the staggered spacing of the stamps. Usually the impressions were resonably well aligned, although a common failing was to misalign the image from true vertical, 'twisting' the image about its center. In the above example, while the transfer roller was properly aligned vertically, it became slightly shifted horizontally when the row was laid down. Which of the two rows was shifted I do not know. Only the imprimateur, or a larger block would show where the platemaker 'went wrong'.
