Define resolution and explain its impact on print quality and file size.

Define resolution and explain its impact on print quality and file size.

• A. Resolution is color depth; higher resolution increases color depth but not file size.
• B. Resolution is image dimensions; higher resolution reduces print quality.
• C. Resolution is the number of colors used.
• D. Resolution is pixel density; higher resolution improves print quality but increases file size; use appropriate DPI for the task.

Answer: (D)

Resolution refers to pixel density, usually described as DPI (dots per inch) or PPI (pixels per inch) for print. When more pixels are packed into each inch, the image can convey finer detail, leading to crisper, sharper prints, especially up close. However, higher pixel density also means more data to store and process, so the file size grows. That’s why you choose an appropriate DPI for the task: for high-quality printed pieces, about 300 DPI is common; for large signs viewed from a distance, 150–200 DPI (or even lower) can still look good while keeping file sizes manageable. So the best understanding is that resolution is about pixel density, and increasing it improves print quality but increases file size. Color depth, image dimensions, or the number of colors are related but separate concepts and don’t define resolution.
