Which issue may occur when a low-resolution image is printed?

• A. Blurring
• B. Aliasing
• C. Pixelation
• D. Noisiness

Answer: (C)

When there isn’t enough pixel data to represent detail at the print size, the individual pixels become visible and the image looks blocky. This blocky, mosaic-like effect is called pixelation, and it happens when a low-resolution image is enlarged or printed larger than its native resolution. Fine details and smooth color transitions break into distinct squares as each pixel is rendered separately.

Blurring softens edges and detail rather than creating blocky squares, aliasing shows jagged edges from sampling, and noisiness appears as random grain. Pixelation specifically describes the visible squares that result from printing with too few pixels.
