Thermal Compositor is an application that converts files from the Heidelberg Delta List format to the DuPont Digital WaterProof/Cromalin proofer format. The package consists of a single application, ThermalCompositor, that can be used manually, or called automatically by the Delta RIP.

Firstly you should install it into your Delta directory. The Delta Rip is then shutdown and the software protection Dongle is attached to the back of the Delta Dongle and the system is restarted.

Thermal Compositor can now be started from the Start menu under Programs for the initial setup.

The Thermal Compositor main window contains the log window, a progress bar that shows job progress, and four buutons, Convert..., Cancel (The X-shaped icon), Options... and Close.

Convert
Runs a conversion manually. When you click, you will get a "get file" dialog. Select the "job.ddc" file of the Delta Job you wisj to convert. Then you will be presented with a "output file" dialog. Select the output directory where you wish to place the output files.

Cancel
Stops the job in progress.

Options
Brings up the Options dialog.

Close
Quits Thermal Compositor.


Options Dialog
The options dialog controls the Delta List conversion.

Gray Density Of...
This controls how CMYK colors are conveted to Gray. The CMYK values of a given color are multiplied by the entered values, then added together to get the gray density. Spot colors are convertd to CMYK, then processed in the same manner. The spot to CMYK conversion is controlled by an included look-up table, which may be edited by the user. The table file is named INKTABLE.txt, and is in the same directory as the ThermalCompositor.exe file.

Output Media
Allows you to select the output material setting. Selecting default passes the material setting from the input Delta job to the output Delta job. Selecting a name from the pop-up menu substitutes that material. The pop-up values are created by putting Delta *.qry files into the same directory as ThermalCompositor.exe.
