Media

The media function adjusts the time that the printhead is turned on (strobe time) to create an image on the media based upon the media type selected. The default setting is light paper. When the plotter is set to film or grayscale mode the printhead’s requirement for strobe times is raised. This requires a slower plot speed in order to maintain the high quality level of the V8.5e.

Note: there are two preprogrammed media tables for grayscale plotting. These calibration tables can be changed for different medias by uploading new tables which can be provided by The Imaging Systems Group Inc. for virtually any approved thermal media. These tables are custom tuned to provide maximum grayscale performance on a selected media. These tables can be uploaded to the V8.5e, where they are stored in non-volitile memory until overwritten. Tables are uploaded two at a time overwriting the factory default tables stored in T1 and T2.

CAUTION: Thermal plotting technology involves high temperatures. Incorrect media or contrast settings can damage the printhead or other components and void the warranty. Media damage can also occur.

VORSICHT: Bei der thermischen Plottertechnologie entstehen hohe Temperaturen. Ungeeignete Medien oder falsche Kontrasteinstellungen können den Druckkopf oder andere Bauteile beschädigen und zu Verlust der Garantie führen. Auch können Beschädigungen an den Medien entstehen.
