PRT-1007
Water-based Print
Water-based printing uses inks with water as the main solvent in place of strong chemical solvents. The ink is absorbed by the fabric, which gives a soft print and a lower environmental load than solvent-based inks.
VISUAL EFFECTS
Soft-hand print integrated into the fabric
HAND-FEEL
Very soft, fabric-integrated
BENEFITS
The print feels soft and keeps the breathability of the fabric, which suits apparel. Water replaces strong solvents as the ink base.
LIMITATIONS
Colours are less opaque and can fade sooner than solvent-based prints. On dark fabrics the print needs an underbase or a dark-garment additive. Drying depends on humidity and temperature, so conditions are set for each run.
PROCESS
[01] Colour Calibration
Calibrate the monitor and printing equipment for accurate colour with water-based inks.
[02] Screen Preparation
Coat the screen with a water-resistant emulsion, then expose and develop it for a clean, precise stencil.
[03] Ink Mixing
Mix the water-based inks to the target colours.
[04] Printing
Load the ink onto the screen and spread it over the fabric with a squeegee, keeping pressure and coverage consistent.
TO CONSIDER
Substrate Compatibility
Make sure the fabric is compatible with water-based inks and can absorb the ink effectively.
Drying Conditions
Optimise drying conditions, taking humidity and temperature into account, so water-based prints cure properly.
Regulatory Compliance
Follow the local regulations that apply to the use and disposal of water-based inks.
