Each “full colour” image is actually an amalgam of the four primary colours – cyan (blue), magenta (red), yellow and black. As such, four colour or “composite” files received by Horton Media need to be separated into these four elements before they can be printed. Each colour’s contribution to an image requires its own plate to be created. By the time the paper has reached the top of a colour tower, it has passed though four printing couples transferring each colour of ink on top of the previous one. The final colour is usually black to allow black text to sit on top of colour images. An offset plate image is designed to attract ink to the image area and repel water onto the non-image area. Ink is fed from the ducts to the plate through a train of ink rollers in order to deliver a smooth film of ink to the image area. This image is then transferred to the paper via a “transfer” blanket – giving offset printing its name. This process produces the fastest and sharpest way of printing an image on newsprint.
