Definitions
- CMYK ink sets comprising a pigment black ink
- Such ink sets and printing method are disclosed for example in U.S. patents 5,734,403 and 6,354,693, and in European Patent Publication 1 ,125,994 A1.
- the pigment particle size should range from about 0.005 to about 5 micron and, most typically, from about 0.005 to about 1 micron.
- the average particle size as measured by dynamic light scattering is less than about 500 nm, more typically less than about 300 nm.
- Pigmented ink jet inks typically have a surface tension in the range of about 20 mN.m “1 to about 70 mN.m “1 at 25°C. Viscosity can be as high as 30 mPa.s at 25°C, but is typically somewhat lower.
- the ink has physical properties compatible with a wide range of ejecting conditions, materials construction and the shape and size of the nozzle.
- the inks should have excellent storage stability for long periods so as not clog to a significant extent in an ink jet apparatus. Further, the ink should not corrode parts of the ink jet printing device it comes in contact with, and it should be essentially odorless and non-toxic.
- the particle size was determined by dynamic light scattering using a Microtrac Analyzer, Largo Florida. For many of the dispersion steps, a Model 100 F or Y, Microfluidics System was used (Newton MA).
