Lithography and other types of lottery charts

[Маруся]

It is for me a hot topic. Help, please, understand. Any other questions (one already asked in the topic terminology, because it seemed the most appropriate of the recent).
What distinguishes lithography (stone acid) from the Silk (small stencil) theory about understand. If not right, content change, please. And, perhaps, from the Print /Estampa is a different use of some other printing techniques ...
Questions:
Is there a limit on the number of colors in lithography?
Is it possible to combine in one paper lithography and silkscreen printing?
Is it possible to distinguish one from another and even from the Print /prints, and how it can be done?

Half a day spent on the search for this topic at the forum, therefore, decided to try to combine that found (certainly not all)

Here the issue was discussed in detail (and very interesting)
