Paper as a material has been known since 105, n.E., That is for a very long time. However, it was not until the twentieth century that more and more types of paper for various applications were invented. And now we have paper chalked, white, slippery, coated with plastics, etc. All this to achieve different results of advertising and journalistic printing.
Recently also a lot of home brewers begin to label their own beers, of course not for trade, but for example for contests.
In addition, we have producers of honey, preserves and organic food, where the demand is rather small expenditure labels.
In principle, everything that comes out of the printing house can be included in the category of printing. There are plants specializing in the production of only a specific group of printed materials: eg leaflets, or only large-format printing.However, this results from a simple thing: for every type of printing you need to have the right machine, and these take up space and cost a lot.
