During final inspection the colour is even but the paper is slightly buckled. What is the most effective future prevention?

Answer and explanation

Correct answer: Tape suitable thick paper to a board on all sides

The governing practical concept is controlling paper expansion during wet painting. Water makes paper fibres swell, and uneven wetting and drying can leave the sheet buckled even when the colour layer is smooth. Option A is most effective because suitable heavier paper, secured on all sides to a rigid board, is supported while it dries. More water increases swelling, folding creates creases, and direct sunlight can cause uneven drying and surface stress.
