Lecture 2 Reflections – Halftone Printing

Halftone printing

In the second lecture, I was very interested in halftone photography.
Examples of Halftone printing are newspaper and photographs.

Previously, newspapers were woodcuts or wood engraving made from hand-carved blocks of wood. It was not recommended as it evolved to mass printing. Commercial printers took on the mechanical printing process. They used halftone printing as it was much more practical.

Examples of Halftone printing are newspaper and photographs.

Halftone printing technique uses discrete dots to form an image, through the different type of size, shape and spacing. It has an optical illusion where you can only view from a distance. The tiny dots on the print gathered and form into a shape smoothly so that human eyes can see clearly. The photographic images must be first to convert into a series of dots to print.

Not only that, there are 3 different types of dot shapes, which are the round shape, elliptical dots and square dots. Also, Lightness and darkness of portions of an image are affected by the size and the density of the dots. The spacing of dots side by side matters when it is nearer or further as it create a lighter area and a cluster dots create a darker area.

The downside of halftone printing
– Details will be lost if the image has a lower resolution
– Does not produce very detail artwork

I felt that it was an impressive start of producing photographs. If there are no halftone printing, it would not have evolved to be able to print photographs now. Halftone has become digital through the usage of lasers.
