The estimated saving of the Ecofont (20%) is based on research with software that compared the average black surface of the letters/signs of the Ecofont to that of the source font Bitstream Vera.
NOTE
The actual savings (the results of printing) depend on two factors:
- the tonal-value increase (TVI) causes a decrease of saving results. In short: the smaller the fontsize, the lower the saving. Paper choice (substrate) also effects TVI.
- the type and age of the used printer
