An intaglio plate is used in the printing process of

(A) Rotogravure

(B) Offset

(C) Rotary

(D) Letter-press

Correct Ans: (A)

Explanation:

The rotogravure printing process uses an intaglio plate to produce high-quality prints. This method relies on engraved cylinders that hold ink in recessed areas, transferring it directly to the printing surface. As a result, rotogravure is ideal for printing magazines, packaging, and currency notes.

Now, let’s examine why the other options are incorrect. Offset printing uses planographic plates, where ink and water repel each other to create images. Rotary printing refers to any method using rotating cylinders but does not specifically use intaglio plates. Letterpress printing, an older method, uses raised type to transfer ink onto paper.

Rotogravure is widely used in mass production because it offers sharp images, consistent quality, and durability. The engraved plate can handle high-speed printing, making it cost-effective for large-scale publishing.

In summary, intaglio plates are a defining feature of rotogravure printing. They ensure precision and longevity, making this method popular in high-volume print production.
