Both public bidding and covert bidding are based on technical tender, with different styles and advantages. This paper will reveal the requirements of making bright and dark marks for you and help you better understand the art of making technical marks.

Free and unrestrained standard

Public bidding has no restrictions on the content, text and typesetting of technical targets, and even the name of the bidder can be displayed generously. Your creativity is the only criterion here.

Strict dark mark requirements (Wuhan)

In Wuhan, there is a set of strict requirements for hidden labels: uniform cover, back cover binding, clear unit name and seal, computer drawing of construction progress map, clear black and white, A4 white paper, No.4 song, No.5 footer, no alteration, special logo, neat layout and clear handwriting.

Strict and meticulous dark mark (Ningbo)

The art of setting technical goals

No matter which style you choose, please show your professionalism and creativity to your heart's content, and let technical standards become the stepping stone to your success.
