What should be checked finally to make a poster colour artwork look clean and professional?

Correct answer: Edges, colour evenness, lettering and unwanted stains

The governing concept is final quality control in a finished artwork. A professional poster should have crisp edges, even colour coverage, readable and correctly placed lettering, and no accidental stains. Option A includes all of these visible quality checks. The paper’s price, the brush’s colour, or the amount of water alone cannot establish whether the completed artwork is neat, accurate, and ready for presentation.
