Water-based ink05
描述
Scope of Application:
Soft mesh fabrics, general sandwich mesh, non-woven fabrics, oxford fabric, EVA material, swimwear, stretch fabric, wetsuit fabric.
Performance Characteristics:
Strong three-dimensional effect, elastic, soft hand feel, excellent adhesion, washable, good tensile strength, capable of producing raised textures and matte/glossy effects, with a special hand feel resembling flocking.
Printing Process:
Screen mesh (50–150 mesh) → Base printing (thick plate) 6+ times → Foam ink printing 2+ times → Layering printing 2+ times → Topcoat clear varnish printing 2+ times → Dry for 24 hours → Foaming (100–150°C, 8–12 seconds)
Operating Instructions – For sandwich mesh material:
Use water-based three-dimensional clear varnish for base printing, adding 3–5% water-based hardener. The base layer must be printed flat; otherwise, the surface may become uneven after foaming. It is recommended to print 6 or more times.
Foam ink mixing ratios:
High foaming – Water-based ink : Foaming paste : Water-based hardener = 100 : 30–50 : 0–2% (optional)
Medium foaming – Water-based ink : Foaming paste : Water-based hardener = 100 : 20–30 : 0–2% (optional)
Low foaming – Water-based ink : Foaming paste : Water-based hardener = 100 : 5–10 : 0–2% (optional)
For layering effects, you may use thick-plate printing to create a three-dimensional effect, or print with water-based ink mixed with foaming paste.
Topcoat clear varnish can enhance gloss or matte finish and helps with abrasion resistance testing, but 3–5% water-based hardener must be added.
Performance Characteristics:
Yellowing resistance grade 4, good flex resistance, good adhesion, excellent three-dimensional effect, good tensile strength, fast film-forming, washable.
Appearance: Milky white paste
Active ingredients: Waterborne polyurethane, defoamer, leveling agent, thickener, wetting agent.
Solid content: 52±1%
Viscosity: (not provided in original text, retained as is)
Storage temperature: Must not exceed 50°C, and should not fall below 5°C.
Usage Instructions:
Leather materials require surface treatment with a primer; mesh fabrics do not require treatment.
Use water-based three-dimensional clear varnish for base printing (recommended screen mesh: 50–150 mesh) with a thick plate. Add 3–5% water-based hardener. The base layer must be printed flat. If used for foaming, an uneven base layer will result in an uneven surface after foaming.
During printing, low-temperature drying on the platen is acceptable, but the temperature must not exceed 80°C.
