As a Nexus user who also uses FlexoSync or LithoSync curves, how do I migrate to PressSync curves?
The Nexus FlexoSync curves evolved from the FlexoCal calibration process, first developed by PCC Artwork Systems. Likewise, LithoSync evolved from the earlier LithoCal process. PressSync is a further evolution of the calibration process that greatly simplifies the process of characterising a press. PressSync is supported by Nexus and Imaging Engine, however, Imaging Engine does not support the older FlexoSync and LithoSync curves.
It is very straightforward to convert FlexoSync and LithoSync curves to PressSync curves.
FlexoSync curves map very closely to the F series of PressSync
LithoSync curves map very closely to the D series of PressSync
So for instance:
FlexoSync_29 becomes PressSync F29
LithoSync_40 becomes PressSync D40
HD Sync Curves
Some Nexus users might have some pre-defined curves referred to as “HD Sync” curves. “HD Sync” was never a released product, but was an unofficial distribution of a set of Symphony calibration files. There is no known direct mapping to a single PressSync series for these curves.
However, it is possible to manually convert these files to PressSync curves. The curves must first be converted to DGC curves using the conversion tool available with Imaging Engine 14. The resulting curve can then be opened in CurvePilot which can show the PressSync curve that best matches it. For more details on PressSync curve matching in CurvePilot, please refer to the CurvePilot documentation.
