Abstract

Disclosed is a method for heating plastic preforms, wherein the plastic preforms are transported along a predetermined transport path and are heated during this transport by applying electromagnetic radiation, wherein an absorption and/or transmission of the plastic preforms is determined for radiation in an infrared wavelength range, wherein an absorption and/or transmission of the plastic preforms and/or of the plastic containers produced from these plastic preforms is determined for radiation in a visible wavelength range.
