What printing technique employs copper rollers engraved with designs to apply multiple colors to fabric in one pass?

The printing technique that uses copper rollers engraved with designs to apply multiple colors to fabric in one pass is known as roller printing. This process involves the creation of seamless patterns and is particularly efficient for mass production. Each roller is precision-engraved to create the desired design, and as the fabric passes through the rollers, different colors can be applied simultaneously. The ability to print intricate designs quickly and with high fidelity makes roller printing a popular choice in the textile industry, especially for creating detailed patterns across wide widths of fabric.

Roller printing is often favored for its speed and ability to produce consistent results, allowing manufacturers to meet high demand efficiently. This technique stands out in contrast to other printing methods, which may involve more time-consuming processes or limitations on the number of colors applied at once. For instance, screen printing requires separate screens for each color, and block printing involves carving individual blocks, both of which can be less efficient for complex, multi-colored designs. Transfer printing typically involves applying pre-printed designs onto fabric using heat, which is not as direct as the roller printing method.
