What is the process of silk screen nameplate printing

Preparation of printing materials and pre press surface treatment ->Preparation of printing materials ->Production of screen printing plates ->Printing ->Inspection and repair of parts ->Corrosion ->Cleaning and drying ->Finished products.

① Surface treatment of the substrate. Copper based and iron-based materials only need to remove the surface oxide layer in dilute sulfuric acid, rinse with running water, and air dry before printing. Aluminum based materials are generally degreased in hot sodium carbonate solution, cleaned and dried before being screen printed on the internet. Organic solvents such as gasoline, banana oil, trichloroethylene, cyclohexanone, etc. can also be used to remove oil stains, or dishwashing detergent, laundry detergent, specialized diluents, etc. can be used. If there are serious pits, scratches, or oxidation spots on the surface of the metal substrate, mechanical polishing or brushing can be used to treat them, followed by oil removal.

② Printing materials. There are many specifications and varieties of printing materials used for silk screen signs, but the printing materials used for corroded sign silk screen graphics and text generally only use corrosion-resistant printing materials. It should have good film-forming properties, easy drying, good mesh passing properties, good corrosion resistance, and easy removal. The commonly used corrosion-resistant printing materials are as follows:

a. Thick paint printing material. Thick paint printing material is a traditional printing material. Thick paint is generally made by using dry oil thick paint and adding a certain amount of phenolic varnish, alkyd varnish, asphalt acid resistant paint, etc

b. The price is customized according to the quantity and specifications.
