LIGHTFAST Meaning and
Definition
-
Lightfast is an adjective that refers to the ability of a material or substance to resist fading or discoloration when exposed to light or ultraviolet (UV) radiation over an extended period of time. It is commonly used in the context of art materials and pigments, particularly those used in painting and printing.
Lightfastness is an important characteristic in art supplies, especially when creating works that will be displayed or exposed to natural or artificial light. Paints, inks, dyes, or pigments labeled as lightfast are specifically formulated to resist the effects of fading or color shift caused by exposure to light. This ensures that the artwork remains vibrant and retains its original color intensity over time.
The lightfastness of a material is determined by its chemical composition, particularly the stability of its color molecules when subjected to light. Materials with high lightfastness ratings are typically resistant to the fading effects of both indoor and outdoor light sources.
Different levels of lightfastness can be indicated through a grading system, such as a scale from one to five, with five representing the highest level of lightfastness. This allows artists and consumers to identify products that will provide long-lasting results.
In summary, lightfast refers to the ability of a material to resist fading or discoloration when exposed to light. It is an important characteristic for art materials, ensuring that the colors remain vibrant and true over time.
