Question

What is the meaning of four different colured dots at the bottom of the newspaper?

Answer 1

When a sheet of paper is passing through a printing press, and the paper has more than one colour on it, the printer needs to know that his machine is printing colours properly.
A modern printing press runs so fast (particularly a newspaper press) that it just is not possible for the printer to look at every part of the sheets of paper to check the colours. So, dots or bars, that represent every colour that should be on the paper are printed near the edge of the sheet, where it's easy for the printer to see them.
If a dot or bar is missing, he knows that a colour is not printing properly. A newspaper is fairly low-grade printing, and newspaper offices are always pressed for time, which means that the coloured dots don't get cut off as they do in bookbinding.

Explanation:

Newspapers print four coloured dots at the bottom of the page called 'registration marks' to ensure that the print is aligned properly. These CMYK (cyan, magenta, yellow and black) colours are the base colours used in printing.
