Identification for Matt Finish and Glossy Finish

Generally, the products in ACEBIKE, there are two options for the outlook:
Matt finish /  Glossy finsh.

And also there are two popular styles for the weave: 3K and UD

So there are four choices for the outlook of items, such as
carbon frames, carbon wheels, carbon rims, and components, etc. :
3k matt / 3k glossy/ UD matt/ UD glossy

Then how to indentify them? Here are some photos for your reference:

3K Glossy:
3K is the most common carbon fiber that you will find externally on a bicycle. 
It provides a comfortable ride while still allowing the bike to be stiff and strong enough to
handle a powerful rider in the midst of his/her best sprint.

12K Glossy:
12K is the largest weave and the stiffest. 
This outer layer featured on the Fascenario 0.8 makes for the  stiffest "feeling"  ride of all three. 
It is slightly heavier and much less expensive to use in production,
hence the price difference in the Fascenario 0.7 and the Fascenario 0.8

UD Matt:
Uni-Directional (UD) carbon is another type of carbon fiber that can be used to create a carbon bicycle. 
UD carbon has fibers that run the same way rather than being woven together. 
This carbon is used on the Fenomalist and Aero UD in the Storck line-up.
