How to tell the difference between micro-jet and original?

Observe color and texture, and pay attention to details.

Observe the color and texture: the original color is usually more natural and the texture is clearer, while the micro-jet color is usually dim and the texture is unnatural.

Pay attention to details: the details of the original work are usually clear, without too much ambiguity and distortion, while the details of micro-jet will appear some ambiguity and distortion.
