Which of the following is a printing process for papers and boards?

• A. Screen printing
• B. Lamination
• C. Embossing
• D. Varnishing

Answer: (A)

Screen printing is a printing method that pushes ink through a mesh screen onto the surface of papers or boards. This makes it ideal for producing bold, opaque colors and can work well on packaging, posters, labels, and decorative boards where other finishes are required. The other options are not printing processes: lamination bonds layers together, embossing creates raised patterns using dies, and varnishing applies a protective or decorative coating rather than printing ink onto the surface. So the option that functions as a printing process for papers and boards is screen printing.
