Typesetting and printing method of folder butterfly suit

Go to a regular printing agency for printing, and just use A3 typesetting. Basically, there is no need to consider the problem of splicing in the middle of the layout. As long as there is not a word in the middle, it can be done. Because of the butterfly suit, the advantage is that you can use A4' s portfolio to show people a complete A3 picture. If it's all A4 paper, it's meaningless to make a butterfly suit. Ordinary binding will do. Butterfly clothes are very expensive.

The white box outside is called bleeding in professional typesetting and printing, and 3 mm bleeding will be reserved in INDESIGN typesetting and will be cut off when binding.

The basis of all the above description is that you must go to formal graphic design and printing, and ordinary shops will not wear butterfly skirts.
