• To flatten — A rare regional or archaic verbal form meaning to flatten, smooth out, ram, or level a surface (especially the soil or soft clay), being partially a shortened phonetic variant or related to the action of flattening.
• Flat color — A uniform, flat, and perfectly homogeneous chromatic surface, obtained by applying paint or printing ink without shading, gradients, shadows, or visible brushstrokes. As an adjective, it describes a visual element or artistic composition made entirely of flat patches of color, eliminating the illusion of three-dimensionality to highlight the structural rigor and two-dimensionality of the form.
• Flatten — To make flat, flatten, squeeze, or level a three-dimensional structure through external force or mechanical processing; as a reflexive verb, it represents the action of losing its natural relief, roundness, or curvature, becoming perfectly plane. In digital design and software, it refers to the process of merging multiple independent compositional layers into a single final two-dimensional image.
• Flattening — The act of flattening and its direct result; the geometric or mechanical transformation of a three-dimensional body through which it becomes flat, plane, or squashed under the influence of pressure, rolling, or percussion forces. In the field of digital graphics, it represents the irreversible process of merging superimposed transparent layers into a single unified two-dimensional matrix.
• Flattened — Having been brought into a flat, plane, or uniform shape through mechanical pressure, deformation, or industrial finishing; in a digital context, it represents a graphic document or image whose initial components and layers have been completely merged. In anatomy and biology, it describes an organ or structure that exhibits a naturally flattened or compressed shape.
