In printing and scanning, “continuous tone” refers to an image with infinite colors for each pixel. This sets it apart from a bitmap image, which can only accommodate a limited number of colors per pixel.
When we print an image, every pixel comprises a cluster of minute dots. The image’s resolution depends on the number of dots per inch (DPI). Higher DPI means greater resolution and more intricate details are captured. These tiny screen dots work collectively to produce the final printed image.
On the other hand, during the scanning process, an image is scanned and converted into pixels. The scan’s resolution relies on how many pixels are present per inch (PPI). A higher PPI translates to increased resolution capacity and enhanced detail capture.
To sum up, continuous tone signifies images with endless color possibilities, while bitmap images have restricted color options. Continuous tones are significant in printing and scanning procedures where capturing nuanced variations is crucial.
Scanning an image involves the capture of pixels, forming a digital representation. The resolution of the scan is determined by the quantity of pixels per inch (PPI).
