Final answer:
The correct option is b) false.The statement about tacking the poster in the bottom right corner to prevent wrinkling during drymounting is false. Drymounting usually requires a center-outward approach for a smooth finish.
Step-by-step explanation:
The statement that you should always tack the poster in the bottom right corner to prevent wrinkling when drymounting is false. The drymounting process, which is used in framing and presenting artwork, posters, and photographs, generally requires applying even pressure and heat across the entire surface of the material to be mounted to prevent any air pockets or wrinkles. Properly adhering to the drymounting techniques usually involves carefully aligning and then temporarily tacking the item from the center, working your way outwards, to ensure a smooth, even bond.
