EXAMPLES OF BLACK GRAIN "SCRAPE BOARDS." (Original size.)
In No. 1 we have a board with parallel ruling, as supplied by the makers; in No. 2, a few strokes of the knife have converted some of the lines into dots; in No. 3, the knife has been used more vigorously, scraping away lines altogether and thus producing plain whites. This, then, gives us full tint, half-tint, and white. Now if we work with pencil or pen on the full tint, building up the drawing precisely as if drawing on plain white card, and then scrape out, as just illustrated, it will be seen what a wide range of "tones" will be suggested.
No. I. No. II.No. III.
The drawing is to be put in first either with crayon, pencil, or ink, and the scraping done afterwards; by this means any mistakes can readily be scratched out; no small consolation to the unpractised. But, on the other hand, a faulty scratch or scrape cannot be rectified, hence the greater need for care.
