Engraving lines as symbols in a scribe coating for preparation of a negative for map production.

• A. Planimeter
• B. Squeeze
• C. Photostat
• D. Scribing

Answer: (D)

In map production, preparing a negative by engraving lines on a coated surface relies on the act of scribing. Scribing means scratching or cutting lines into a coating so those lines become the defined symbols or features that will be used to create the negative image for printing. The lines formed by this process will hold ink in the printing stage, producing the reversed image needed on paper. The other terms don’t fit: a planimeter is a device used to measure areas on a map, not to engrave or prepare a negative; a photostat is a photographic copying method, not an engraving technique; and squeeze isn’t a standard term for creating engravings or negatives in map production.
