3.1 Set Speed & Darkness
Quality of prints depends on the material (paper, polypropylene, PolysatTM,etc....) and on the print ribbon
you use. Darkness (temperature of the printhead) is expressed by a scale of densities (0 > 15). Setting
the temperature (darkness) too low causes a pale print. Setting the temperature too high can cause
damages to the print head because the print film then melts on it. Differences may occur from one printer
to another. The following values are average settings for some Teckna materials and print films.
