Fine dots vary in size in poster colour work. Which control is most important?

Correct answer: Equal paint amount and pressure for each dot

The governing concept is brush control in dot application. Dot size is mainly determined by how much paint is loaded onto the brush and how firmly or long it touches the paper. Using a similar load and steady, light pressure produces repeated dots of comparable size. An excessively wet brush spreads the paint and creates larger, irregular marks. Different colours or changing paper do not control dot dimensions. Thus option A is correct.
