[2×2 marks]

Use notes and/or sketches to describe how your chosen process is used to make products.

My chosen manufaturing process is Offset Lithography

A printing process used in the mass production of very long print runs.

Prints in a combination of cyan black, magenta and yellow inks (CMYK) to produce a product

Make use of an aluminium plate exposed to a laser image.

Ink and water are applied to rollers from the plate roller. Water keeps the rollers wet to avoid inks sticking due to the different densities of the liquids and the inability of them to diffuse.

Image from plate cylinder is transferred to rubber offset cylinder (mirror image of final print) before transferred to final material.

Process is repeated for each of the four colour.

Registration mark used for quality control.

Uses roll stock form.
