Tekenwaarde

Tekenwaarde is a Dutch term that refers to the tonal intensity or light‑dark quality of a line, shape or surface in visual representation. In practice it describes how much a mark or area deviates from a neutral mid‑tone toward either a lighter (high) or darker (low) value. The concept is central to drawing, painting, printmaking and graphic design because it determines the perception of form, depth, texture and mood.

The notion derives from the broader visual‑arts concept of “value,” which is one of the basic elements of art alongside line, shape, colour and texture. While colour deals with hue and saturation, value concerns the relative brightness of a mark irrespective of hue. In monochrome media, such as charcoal, ink or pencil, the range of tekenwaarde is the primary means of modelling three‑dimensional objects on a two‑dimensional surface.

Artists achieve different tekenwaarden by varying pressure, tool size, material density or by applying techniques such as hatching, cross‑hatching, stippling or blending. In print production the term also appears in the context of tonal values reproduced by halftone screens, where each dot size corresponds to a specific tekenwaarde that the printer must render accurately to maintain image fidelity.

Understanding tekenwaarde is essential for visual communication because the eye interprets contrast and gradient to infer spatial relationships. Proper control of tonal contrast can lead to realistic rendering, emphasize focal points or convey atmospheric effects. Educational curricula in art schools typically include exercises that train students to observe, measure and reproduce a full scale of tekenwaarden, from the deepest black to the brightest white, to develop a nuanced visual language.
