pisteverkko

Pisteverkko, a Finnish term often translated as "point network" or "dot grid," refers to a method of representing or creating images using a series of discrete points or dots. This technique is fundamental to various visual arts and technologies. In digital imaging, it's the basis of pixel-based graphics where an image is composed of a grid of tiny squares, each assigned a color value. Similarly, in traditional printmaking, stippling is a form of engraving or illustration that uses dots to create shading and tonal effects. The density and arrangement of these dots determine the perceived lightness or darkness of an area.

The concept of pisteverkko extends to other fields. In cartography, for instance, dot density maps use the number of dots in a given area to represent the concentration of a phenomenon, such as population or rainfall. This visual shorthand allows for quick interpretation of spatial data. In early printing technologies, like the halftone process, continuous tone images were converted into a pattern of dots of varying sizes, enabling their reproduction on printing presses. The underlying principle remains consistent: conveying information or creating an image through the strategic placement and density of individual points.
