This printing method is an intaglio process, where the printing is done from lines cut into the metal:

Question

Accepted Answer

The correct option is 2:
Roller printing is the industrial application that utilizes the **intaglio** principle for high-volume textile production, making it the correct answer. The fundamental definition of intaglio, which comes from the Italian word *intagliare* meaning 'to engrave,' is a printing process where the ink is held in lines or depressions cut below the surface of the printing plate or cylinder. In roller printing, the intricate design is precisely engraved onto a heavy copper or steel cylinder—the *metal* mentioned in the question. During the printing operation, the entire surface of the roller is coated with a liquid dye or printing paste. A specialized mechanism, known as a 'doctor blade,' then carefully scrapes the surface clean, leaving ink only within the fine, cut lines of the engraved design. The fabric is subsequently passed between this engraved cylinder and a heavy-pressure roller, which forces the cloth deep into the depressions to pick up the ink, thus transferring the design from the lines *cut into the metal*.

The incorrect option is 1:
Block printing is incorrect because it operates on the **relief printing** principle, which is the direct opposite of intaglio. In relief printing, the areas of the design that are *not* intended to print are cut away, leaving the image standing *in relief*, or raised, on the surface of the block. The ink is applied only to this raised surface using a roller (brayer), and then this elevated area is pressed against the fabric or paper to transfer the design. This method typically uses wood or linoleum blocks, not metal rollers with cut lines that hold the ink in recessed areas. Furthermore, block printing is a slower, manual process, whereas roller printing is a high-speed mechanical operation. Therefore, since the question specifically mentions an *intaglio* process, block printing cannot be the correct option.

The incorrect option is 3:
Screen printing, also known as serigraphy, is an incorrect choice because it is a **stencil** or **planographic** method, not an intaglio process. In screen printing, a design is created by blocking out certain areas of a porous mesh screen to create a stencil. The screen remains flat, and ink is pushed *through* the open, unblocked areas of the mesh using a squeegee to transfer the image directly onto the substrate beneath. The process does not involve any lines cut into a metal plate below the printing surface. Thus, screen printing fundamentally differs from intaglio, which relies on recessed areas to hold the ink.

The incorrect option is 4:
Batik printing is incorrect because it is not a printing method at all, but a **dye-resist** technique. The primary characteristic of Batik is the application of melted wax to fabric to resist the penetration of dye. The areas coated with wax remain the original fabric color when the fabric is submerged in a dye bath. After the dyeing process is complete, the wax is removed to reveal the finished pattern. Batik does not involve the mechanical transfer of ink from an engraved plate. It is a traditional hand-dyeing method that utilizes wax and immersion dyeing to achieve its characteristic patterns, completely unrelated to the intaglio process described.
