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.
That is why printing plants limit the amount of services provided.
In this work, many things may go wrong: change of paper for another, new printer with other inks, incorrect conversion of colors.There are also typo errors, bad placement of some element or just a few details.
All this can end very badly and bring big losses - so it's work under stress and tension, because if something goes wrong it usually will be just for the DTP operator.
From simple leaflets to large banners or window stickers.With such a broad concept, it is sometimes difficult to say what the printing company specializes in. Some factories are choosing low-volume small-format prints, others for stickers, and others only for large-format printing.
