Screen printing different production methods

First, the production of screen version according to the different raw materials, its methods can be divided into liquid type direct method photosensitive adhesive plate, pre-sensitized direct film (water film) plate, indirect film plate making and so on.

1, liquid type direct method photosensitive adhesive

The advantages of photosensitive adhesives are simple, economical and practical. Its characteristics are fast exposure, screen durable and easy to remove film, excellent resistance to solvent, its production process is:

Net processing and network selection → glue → glue → drying → exposure → development → standby

Its working environment is temperature 15 ~ 20 °C, relative temperature 50 ~ 65%, under the yellow light darkroom operation.

2, Shuifeilin law making method

Process flow: net processing and networking → film → drying → exposure → development → standby

3, capillary photosensitive film

Pre-treatment (including screen coarsening and degreasing) - Attaching film - Film drying - Exposure

4, photosensitive paste plate making method

Method: A certain thickness of photosensitive paste (usually a diazonium salt photosensitive paste) is coated on a stretched screen plate, dried after coating, and then placed in a printing machine with a plate-making film and exposed, followed by development and rinsing. After drying, it becomes a screen printing screen.

Process flow: Photosensitive paste has been stretched - Degreasing - Drying - Coating - Drying - Exposure - Development - Drying - Revision - Final Exposure - Closure

5, photosensitive film direct plate method

Method: Photosensitive film commonly known as water film, is a transparent plastic film with a thickness of 0.1mm as a film base, coated with a layer of a certain thickness of emulsion on one side, when used, first fully wet the screen, and then paste The upper membrane and the membrane are adsorbed onto the screen by capillary action. After drying, the plastic substrate is peeled off for exposure and development to finally obtain the desired pattern.

Process flow: already stretched - degreasing - wet - film - drying - reinforcement - exposure - development - drying - revision - closure network

Second, direct and indirect plate making method and indirect plate making method

1, direct and indirect plate making

Method: Direct and indirect plate making method is first in the plate-making process, coated with a photosensitive material wrist film-based photosensitive film face up on the work surface, will stretch the wrist frame lying on the film base, and then in the frame Put the photosensitive paste and apply it with a soft scraper. After drying, remove the plastic film base. Attach the photosensitive film wrist net to the printing plate. After developing and drying, make a silk screen plate.

Process flow: stretched net - degreasing - drying - peeling film base - exposure - development - drying - revision - closure net

2. Indirect plate making

Method: Indirect platemaking method is to indirect film first exposure, with 1.2% H2O2 hardened with warm water, dry after making a peelable graphic film, plate the film with the negative side of the film surface with a tight meshed The film was affixed to the wet silk screen by squeezing, the film base was peeled off, and the screen printing screen was made by drying with the wind.

Process flow: 1). Netted - Degreasing - Drying

2). Indirect film - exposure - hardening - development

1and2 - Fitting - Blow Drying - Revision - Closure

Third, the screen printing plate can be divided into operating technology according to: cutting film and photosensitive printing plate making plate

1. Sealing film net printing plate

Process flow: Formulation and production of paint film - Sealing film paper - Stretching net - Previous edition - Closure net

2, photosensitive printing plate making

Process flow: photosensitive printing recipes and production - exposure, show Chang
