Subtractive
Subtractive is a fundamental color mixing principle and methodology in design where colors are created by removing or absorbing specific wavelengths of light from white light or a light-colored surface, commonly employed in printing, painting, and various physical color reproduction processes. This approach operates on the principle that when light hits a pigmented surface, certain wavelengths are absorbed while others are reflected, determining the perceived color. The primary colors in subtractive mixing are cyan, magenta, and yellow (CMY), which work by subtracting or absorbing their complementary colors - red, green, and blue, respectively. When combined in varying proportions, these primaries can produce a wide spectrum of colors, with their complete mixture theoretically resulting in black, though in practical applications, a separate black component is often added (CMYK) to achieve true depth and save on colored inks. This color system is particularly crucial in professional printing processes, where precise color reproduction is essential for maintaining design integrity. The subtractive method stands in direct contrast to additive color mixing, which is used in digital displays and involves adding different wavelengths of light together. The historical development of subtractive color theory has significantly influenced modern design practices, from traditional art techniques to contemporary digital-to-print workflows, and continues to be a cornerstone of color management systems evaluated in prestigious competitions such as the A' Design Award's printing and packaging categories.

Subtractive
Subtractive is a manufacturing process that involves the removal of material from a solid block or piece of raw material to create the desired shape or form. In contrast to additive manufacturing, where material is added layer by layer to build an object, subtractive manufacturing starts with a larger piece of material and removes portions of it through various methods such as cutting, drilling, milling, or grinding. This process is commonly used in traditional manufacturing industries, including metalworking, woodworking, and plastics fabrication. Subtractive manufacturing allows for the creation of complex geometries and intricate details, and it is often employed for producing high-precision components, molds, and prototypes. The choice of subtractive manufacturing techniques depends on factors such as the material being used, the required level of precision, and the production volume. Some common subtractive manufacturing methods include CNC machining, laser cutting, water jet cutting, and electrical discharge machining (EDM). While subtractive manufacturing has been a staple in various industries for decades, it has faced challenges in terms of material waste and limitations in creating certain complex geometries that can be more easily achieved through additive manufacturing processes
