Brisque Version 4.0.97.23 and Lotem ThermoFlex — Release Notes

Requirements:

• Lotem ThermoFlex can be connected to Brisque version 4.0 only via TSP.
• Lotem ThermoFlex version 1.20.08 or higher.
• Brisque Version 4.0.97.23 (FP).
• Install the following optional updates from the Brisque version 4.0.97.23 Product CD 2, as detailed in the Brisque 4.0.97.23 Full Production Release Notes (PDF 324 KB):
  • Upd_Brisque4_Flex - 4.0.97.5
  • Upd_Brisque4_ExposeJRE - 4.0.97.4
  • Upd_Brisque4_97_TiffArrange - 4.0.97.7
• Make sure that the Machine Type on the PC controller is defined as either the LotemFlex4045 or LotemFlex2630 to ensure that screen and plate sets are correctly recognized.

New Features:

• Version 4.0 supports MultiSep in one pass for each of the 4 separations.
• Multi Sep and Step&Repeat can not be enabled at the same time.
• Filter Option
  • The Filter option, which is part of Version 4.0, produces an outfile file called Name.filter or in case of rotated files, Name.rot.filter.
  • This option is built into the software and is designed to obtain a clean plate, without losing any data, particularly in the highlight dot area, 0%-1%, and vignettes noisy areas.
  • The ThermoFlex system, together with Brisque 4.0, eliminates unwanted small printing dots (< 25 microns) during the exposure operation by filtering out the small dots that have values less than 1% of dot area.
    This produces an exposure with dots that are output at the minimum size that the printer supports, thereby producing a clear image. The required dot size is set by the Tone Reproduction curve.
• Multi Beam option
  • This option is installed with the Upd_Brisque4_Flex (4.0.97.5) and Upd_Brisque4_ExposeJRE (4.0.97.4) updates.
  • The FlexoTable application enables the service engineer to optimize and clear the Screen Set from unwanted effects by determining the optimum number of laser beams that the ThermoFlex platesetter will use to expose the separation.
  • The FlexoTable application searches the table for the specific Screen Set parameters. When found, it returns the optimal number of beams for the exposure.
  • The table maintained by this application is saved locally on Brisque and may be backed-up. When needed, the table may be restored from its backup location.
  • For detailed information, refer to the Lotem ThermoFlex Flexo and Table for Multi Beam Option User Guide (PDF 248 KB).
• TiffArrange option
  • This option is installed with the Upd_Brisque4_97_TiffArrange - 4.0.97.7 update.
  • The TIFFArrange option enables you to arrange multiple TIFF files in a single layout by dragging one-bit TIFF files onto the Preview icon.
    Limitation: If the layout includes files with different orientations (e.g., 0 and 90), more than one pass will be needed to expose the layout, thereby increasing the expose time. To avoid producing more than one pass to expose a layout, arrange all files using the same orientation.
