Road traffic signs are very important traffic facilities on the road, so do you know the production method and processing process?

(1) Base plate production
Most of the text and graphic plate making of road signs use phototypesetting and photo platemaking. First, a single original version is produced, and then the continuous printing machine is used to make the imposition. When imposing, according to the accuracy required by the parts, the imposition without spacing and imposition with spacing can be used respectively.

(2) Positioning
The rules on the screen printing plate for making road signs are the technological means to ensure the accurate and uniform position of the graphics on the same surface of the workpiece to be printed and to meet the requirements of color overprinting accuracy. According to the different materials and shapes of the substrates, the positioning methods for the production of silk screen road signs are also different.

(3) The deployment of ink
The requirements for screen printing ink for metal road sign production are strong adhesion, good wear resistance, clear graphics after printing, fast drying and no mesh sealing. Metal sign screen printing oil is generally a special ink made of synthetic resin such as alkyd and phenolic as a binder, adding some pigments and additives.

(4) Quality requirements for screen printing signs
The text, scale, graphics, positioning holes and color of the silk screen printing of road traffic signs should meet the requirements of the drawings, the surface of the finished product should be free of obvious scratches and stains, and the adhesion of the ink film should meet the requirements.
