Evaluating Screen Engraving Amortization against Digital Print Ink Efficiency
Digital print delivers lower landed cost below 6,000 meters; rotary screens prove economical for longer runs once setup fees and fabric waste amortize fully.
ISO 105 Fastness Standards
Standardization Framework
Standardized testing protocols establish internationally recognized procedures for evaluating color resistance in dyed and printed textiles under physical and chemical stress. ISO 105 fastness standards cover over fifty individual test methods measuring resistance to washing, light exposure, rubbing, dry cleaning, and perspiration. Commercial buyer contracts specify these exact standards to establish baseline quality compliance.
Test Methodology
Testing laboratories mount fabric samples alongside standardized adjacent fabrics before subjecting them to controlled laundering or xenon arc light exposure. ISO 105 fastness standards prescribe exact liquid temperatures, detergent formulations, steel ball friction, and exposure durations for each trial. Laboratory technicians run ISO 105 C06 for wash fastness and ISO 105 X12 for crocking fastness.
Grade Scale
Visual and spectrophotometric comparisons rate shade change and staining against standardized grey scales. Results under ISO 105 fastness standards range from grade one indicating severe color loss or heavy staining to grade five indicating no change. Apparel buyers typically demand a minimum grade four for wash fastness and grade three to four for wet rubbing fastness.
Compliance Scope
Tests designed for natural fibers do not accurately evaluate technical synthetic membranes. Specialized end uses like outdoor automotive upholstery require modified light exposure cycles exceeding standard garment fastness parameters.
