Science and technology are changing with each passing day. Every new technology and new achievement brings to mankind the convenience and great progress of production and life. In order to adapt to the further development of the society and the various needs of users, expanding the production process of Ming and signage is the goal that the technical personnel in the signage industry have been pursuing.
After learning through the business and consulting the materials, we found a new type of inscription and sign making material, a photo-imaging anti-etching anti-plating decorative ink.
Color method, aluminum oxide surface sandblasting, corrosion production (convex) word and other processes.
The following describes the production method of direct printing process: the selection of aluminum (copper) material, the process flow according to the user's drawing size and font pattern requirements, the computer laser to make the photosensitive film (yin, sun version), pay attention to the use of high transparency film .
Pretreatment of materials - brushing - light imaging ink screen printing - pre-drying - exposure - development - drying - punching - cutting shape - spray varnish (1) screen printing surface covered with a protective film, be careful The screen printing industrial film was peeled off, and the surface of the sheet was wiped clean with a soft cotton cloth and 120# gasoline.
The oil residue remaining on the material is commonly used in the chemical degreasing process as follows: the block material that has been degreased is brushed or hand polished and shot blasted with a brushing machine.
Light imaging ink screen screen printing color according to user requirements, there are red, yellow, blue, green, black, colorless and so on. Screen printing light imaging ink is an important process, the ink viscosity is 100~200dpa-s, the temperature is 25C, it needs to be fully stirred and left to stand for about 30min. The technology at the time of printing relates to the exposure and adhesion of the ink.
Development was carried out in ASA-SA8 model 4000W high power exposure developing solution 30~40L.
After the dry running water is rinsed out, it is placed in an oven for baking. The temperature is 145~150C, 60min. The punching is punched according to the user's drawing requirements, and the layout is not allowed to be scratched.
The shape of the cut is cut out according to the dimensions of the drawing, and the shape of the workpiece must not be scratched.
The surface should be smooth and free of particles.
Compared with the nameplate printed on the ordinary screen, the above-mentioned method has the advantages that the handwriting stroke is smooth, the three-dimensional feeling, the drawing without the ink sticking, the screen printing micro-saw and the hairpin phenomenon, the adhesion Firm, the variety of colors increases, and the color is bright. In addition, compared with the corrosion method, the process is small and the cycle is short, and it has been applied in several sign panels. Ideal for large, medium and small batch signage and panel production.
As long as we can strictly follow the process flow and carry out strict operations on each process, and constantly track and learn new technologies, new processes and new materials for domestic and foreign sign making, and communicate with our peers, we will be able to produce higher quality and level. Ming, signage.
