Rasteripiste

Rasteripiste is a Finnish term that translates to "raster point" or "dot". In the context of printing and digital imaging, it refers to the individual dots of color or ink that make up a printed image or a digital raster graphic. These dots are the fundamental building blocks of raster images, which are composed of a grid of pixels.

In traditional printing, rasteripiste refers to the halftone dots used in the printing process. These dots are varying in size and spacing to create the illusion of continuous tones and shades. When viewed from a distance, the human eye blends these dots together, perceiving a full range of colors and tones. The density and pattern of these halftone dots are crucial for the quality of the printed image.

In digital imaging, the term rasteripiste can be used interchangeably with "pixel." A pixel is the smallest controllable element of a picture represented on a screen. Each pixel has a specific location and color value, and together they form the complete digital image. When a raster image is displayed on a screen or printed, it is essentially a grid of these individual rasteripiste. Understanding rasteripiste is fundamental to comprehending how images are captured, stored, displayed, and reproduced.
