Resolution measures the:

Resolution is a critical concept in the field of advertising design, particularly when it comes to images. It refers specifically to the sharpness or clarity of an image, which is determined by the number of pixels it contains. Higher resolution images have more pixels, allowing for greater detail and a clearer presentation. This is especially important in print media, where higher resolution can result in crisper lines and finer details that enhance the visual quality of the design.

When we talk about resolution in the context of images, we typically refer to pixel density, which can be quantified in terms of pixels per inch (PPI). This measurement directly affects how well an image will reproduce across different formats, whether in print or on digital screens.

The other options relate to different aspects of printing and design but do not pertain to image quality. The weight of paper concerns its heaviness and sturdiness, color quality involves the accuracy and vibrancy of hues, and the thickness of paper focuses on its physical dimensions rather than visual clarity. Understanding resolution is essential for producing high-quality visuals that meet the standards of professional advertising design.
