How to tell whether a calligraphy work is genuine or printed?

Printed matter can be seen with a magnifying glass or close range that there are many tiny squares, which have the smell of ink. The work is unnatural and looks stiff and rigid. Even when viewed from the side, the work will be reflected by ink, just like a painting on coated paper. The paper is simple or even rough.

The works written have the taste of pigment or ink, and the pen and ink are smooth, vivid and natural. The paper is made of advanced creative paper (such as Xuan paper sketch paper canvas).

These are simple and effective methods to distinguish whether a work is printed or created. I wish you know the authenticity of the work as soon as possible!
