Quality Control Procedures
Incoming Raw Materials
All incoming raw materials are tested to a specification to ensure that they are correct before manufacturing any finished product.
Dyestuffs are tested for colour shade, strength and solubility, distilled water for pH and surface tension, solvents, humectants and penetrating additives are tested by GC analysis.
Finished Products
Finished product is tested for Viscosity, pH, Surface Tension, Colour Strength, Colour Shade and Conductivity to set standards so we can guarantee batch to batch consistency.
Printability
Printability is checked by refilling cartridges for a Canon, Epson and HP printer and printing a test pattern.
Filtration Specification
All inks are filtered through a 1.0 micron cartridge micropore filter and a 0.2micron cartridge micropore filter in tandem to guarantee that the inks are filtered to a level of 0.2microns.
