Which aspect of graphic design does "resolution" primarily affect?

Resolution primarily affects the clarity and detail of an image. In graphic design and digital imaging, resolution refers to the amount of detail an image holds, which is usually measured in pixels per inch (PPI) or dots per inch (DPI). A higher resolution means more pixels are packed into the same physical space, which results in a clearer, more detailed image. This is crucial for producing high-quality prints and ensuring that images remain sharp and well-defined, especially when scaled or viewed at larger sizes. Clarity in design is vital for effective communication and visual impact, making resolution a fundamental characteristic in graphic design.

While the other options touch upon relevant factors in image handling, they do not directly relate to the primary role of resolution. Color accuracy concerns how true colors appear on different displays, rendering speed relates to how quickly an image is processed by a computer, and file size pertains to the storage space an image occupies, none of which fundamentally define the clarity and detail that resolution impacts.
