Reverse every other strip is used to prevent what issue in wallpaper installation?

• A. Avoid Wallpaper Shading
• B. Improve Adhesion
• C. Change Color
• D. Reduce Warping

Answer: (A)

The idea being tested is how alternating the direction of wallpaper strips helps hide subtle color differences between strips. When wallpaper is printed, each strip can have a tiny variation in tone. If you hang all strips in the same direction, those slight differences can line up at the seams or along the wall, producing a visible band or shading that looks uneven as light hits it. By reversing every other strip—flipping the next strip end-for-end—the small tonal differences are distributed rather than aligned. That way, any difference in shade blends more evenly across the wall, reducing the appearance of shading.

This technique doesn’t change adhesion, color, or warp-related issues; it’s specifically about balancing tonal variation to achieve a more uniformly lit look.
