Production of conventional toner requires a relatively high amount of time, energy and costs. The approximately 6.5 to seven micron toner particles adhere by their low homogeneity also not optimal on the paper, resulting in low grade in an unfavourable ratio between the required and the actual "verdruckten" toner amount. Produced by mechanically produced colour toner layer is usually between five and seven microns thick.
Chemically produced toner emulsion since the 1990s on the market. Their particles are formed by chemical deposition in an emulsion of latex polymers, resin and water. Compared to conventional toner they are on average only half the size and have a very homogeneous consistency, which is during the production process arbitrarily adjustable. It follows from the great homogeneity of chemically produced toner is a very economical consumption - for an excellent and resilient print only paint from about two to three microns are necessary.
The fixing of the toner to the paper emulsion is without oil and as a rule by the wax components of the toner, which leads to very natural and somewhat dull color results. Through the lower melting temperature of the toner, which is often already a mere 65 degrees Celsius, in comparison to conventional toner also greater assortments of different printing papers used.
