Graphics lithography
Lithography is quite complicated and time-consuming graphic technique - you draw on properly prepared stone, to print a graphic from it.
Each subsequent color requires another die - and so the next stone, which can be applied after drying the previous print.
Prices of graphics are different - each copy has a different number in terms of effort, as well as the length of inputs differ from each other.
