An essential part of a print product is, of course, the ink. It may come as a surprise, that ink only forms a mere 2% of the total weight of the product, even though it covers a large surface area. This is, in part, thanks to the uniqueness of offset-printing. Desired colours are achieved by combining four different colours into a raster image. That is, a printed image consists of coloured dots, which can easily be seen under a strong magnifying glass or microscope. If you look closely, you will see a lot of white space in between the dots. This is because white is used to dampen the intensity of the dots and thus achieve both the desired colour and a reduction in ink consumption.
