Thermal Model
The thermal model can be characterized as follows:
•
It is a mathematical description of the interaction Film – TH.
•
It uses parameters like film thickness, thermal conductivity of the film, TH
temperature, environmental temperature, print speed and resolution of the print
head.
•
The thermal model TMML (Thermal Model Multi Layer; R&D name of the product
Æ
official name 'A # Sharp') describes this interaction very accurate, leading to a
very precise reproduction of the image.
•
With the thermal model "TMML" the image looks very sharp and has the image
quality of a Laser Imager.
