Marking techniques refer to various methods used to create visible marks or impressions on surfaces. These techniques are commonly employed in industries such as manufacturing, construction, and art. Examples include engraving, screen printing, and stamping, each serving different purposes and materials. These techniques can be categorized into two main types: permanent and temporary. Permanent marking methods, like laser marking, create lasting impressions, while temporary methods, such as chalk marking, can be easily removed. The choice of technique often depends on the desired durability, material type, and application requirements.
