Roller printing is a modern continuous textile printing technique where a heavy copper cylinder engraved with the print design is used to transfer ink onto fabric. The roller printing process involves a color doctor, doctor blade, engraved roller, lint doctor, blankets, back grey, and furnishers to transfer multiple colors of ink in a single pass onto the fabric from the engraved roller. While it allows for higher production speeds and more complex designs than traditional block printing, roller printing has disadvantages such as not being able to print large designs, lower coloring effects, and defects that can occur in the engraved roller.
