In offset printing, the plate image is transferred to
(A) Rubber blanket
(B) Paper sheets
(C) Paper maché plate
(D) Plastic foils
Correct Ans: (A)
Explanation:
Offset printing uses an indirect image transfer process. The plate does not print directly onto paper. Instead, the image first transfers onto a rubber blanket, which then prints onto the final surface.
This method improves print quality and durability. The rubber blanket adapts to different textures, ensuring even ink distribution. As a result, prints appear sharp and consistent.
Additionally, the rubber blanket helps protect the printing plate. Since the plate does not make direct contact with the paper, it lasts longer. This reduces the need for frequent replacements and lowers costs.
Offset printing works well for large-scale production. Newspapers, magazines, brochures, and packaging materials commonly use this technique. It allows for high-speed printing without sacrificing precision.
Furthermore, this method supports different paper types. The flexible rubber blanket enables printing on rough, smooth, and coated surfaces, making it highly versatile.
Without the rubber blanket, offset printing would be less efficient. Direct printing could cause ink inconsistencies and plate damage. The blanket ensures a smooth and reliable process.
In conclusion, the rubber blanket plays a vital role in offset printing. It enhances print quality, extends plate life, and enables large-scale production with excellent results.
