PerfX Press curves™
Several international standard or method (ISO 12647-x, SWOP, SNAP, GRACoL, etc.) define the tonal characteristics and press gain (TVI), according to various printing processes, inks and paper usage. These specifications defines the required press curves in order to insure optimum and standardized printing reproduction.
PerfX Press curves™ is a software that allows to produce data for press curves (CTP) in order to optimize and to standardize the tonal color reproduction on press. The standard (or curve specifications) can be imported, measured or typed in directly in PerfX Press curves™. Then, a color target is printed on press and read with a measuring instrument (spectro-densitometer) in order to define the current characteristics of the press. PerfX Press curves™ then calculates automatically the curve correction values that have to be applied to the plates (CTP) so that the press (or printing process) can print in accordance to the desired reference standard. A report shows the desired and calculated values, automatically generated by PerfX Press curves™.
PerfX Press curves™ does not replace the need to produce ICC profiles. It allows to produce an optimized characterization, according to a defined standard. The ICC profiles ICC have nonetheless to be produced for color proofing, soft proofing and conversions.
Benefits
- Allows standardizing and to optimize several press according to a reference standard.
- Allows calculating curves for different screening (conventional AM, stochastic FM, hybrid) and linescreen.
- Allows calculating press curves of different printing process, paper or ink, to reproduce consistenly, a same reference gray balance.
- Using optimized curves, allows faster press make ready.
- Color printing jobs can be transferred from one press to another without color consistency problems.
Features
- Automatic calculation of press gain curves.
- Automatic calculation of reference gray balance curves.
- Reference, measurement and corrections data point can be set according to the desired number.
- Support directly the following measuring instruments: Eye-one, Pulse, 528 and 530.
- Compatible to the CGATS 15 standard for the reference and measurement definition data file.
- Graphs showing the curve’s data of the measured, corrected and press gain.
- Produces a printed report, showing the reference, measured and of correction data for each press curves.
- Saves curve’s working sessions.
