Then how to classify the categories of banner products?
Firstly is the application of banner in political sense, of which the national flag, party flag, military flag and league flag are the more representative banner products. However, there are many regional flags in different countries of the world, which increased the difficult of flag printing and production due to uniqueness of products.
Another is the identifying banner. For example, government agencies, non-governmental organizations and production companies tend to use bright banners as their own representatives, which are also symbol of unit’s image.
Common sense of using international code of signals
Full flags, I believe everyone is familiar with it. The form of hanging signal flags from the bow of the ship to the mast, then from the mast to the stern is called the full flags. Whenever a National Day, a major celebration or holiday, merchant ships or warships moored should be full of flags for celebrations. The main method is to match all the international signal flags according to their shapes (square flag and trapezoidal flag, generally 2 square flags with 1 digital flag) and colors. Tract from the bow of the ship to the mast, then from the mast to the stern through flag rope and tackle; then connect the matched international signal flags to the extension cable.
Banner retraction and communication: Banner communication is usually suspended one at a time, which cannot be fallen down until the ship (shore station) receiving the signal gives the response. The order of reading is: the mast, the horizontal tension between the masts, and transverse masthead (right and left, outside to inside)
