Example of a OneRun target, containing the IT8 target with the P2P

The OneRun target, in combination with Curve3’s VPR (Virtual Press Run) module, makes it possible to calibrate a printer to G7, using multiple papers, and make profiles for the printer - all in one press run. The beauty here is that you only have to print one target, on one press run to do all this. Press calibration and profiling can’t get much easier than this! The OneRun feature is included in all versions of Curve2 starting with version 2.1.

This is how it works: To save on space, time and reduce measurement error we’ve created new, hybrid targets that combine the P2P target with IT8 and other profiling targets. Redundant patches have been removed and the resulting target is smaller and easier to place on a variety of printing forms. Your measurements of this single target, printed on all your papers, are fed into the Curve software. The software extracts the individual targets from the OneRun target using the P2P patches for curve calculation and the IT8 patches for VPR curving. All of your papers + one target = OneRun. Other OneRun targets incorporating alternate profiling targets will also be available.

Here is a quick overview of this process:

When it comes time to implement Virtual Press Run (VPR), you merely browse to the location where you saved the IT8 on your hard disc.

OneRun targets - procedure

The OneRun target, in combination with Curve3’s VPR (Virtual Press Run) module, makes it possible to calibrate a printer to G7, using multiple papers, and make profiles for the printer - all in one press run.  The beauty here is that you only have to print one target, on one press run to do all this.  Press calibration and profiling can’t get much easier than this!


This is how it works:  To save on space, time and reduce measurement error we’ve created new, hybrid targets that combine the P2P target with IT8 and other profiling targets. Redundant patches have been removed and the resulting target is smaller and easier to place on a variety of printing forms. Your measurements of this single target, printed on all your papers, are fed into Curve2 or Curve3.  The software extracts the individual targets from the OneRun target using the P2P patches for curve calculation and the other patches for VPR curving and profiling. All of your papers + one target = OneRun.  


Currently we have OneRun targets which incorporate:

  • The P2P target and the IT8 target (most popular for press profiling)
  • The P2P target and the HC2052 target (a larger press target containing more neutrals and darker patches). The HC2052 was developed by Don Hutcheson.

Specify:

  • What size target you would need (based on the size of your press and your measuring equipment),
  • Whether you want the IT8 version or the HC2052 version,
  • Whether you measure using Colorport, MeasureTool, or i1Profiler.

Example of a press sheet with a OneRun target

Print your press sheet on your press using the usual procedures for running an initial G7 press run.

Measure OneRun target

Dialog window in Curve2

Measure the OneRun targets from your press run, and save the measurement files.

Bring measurements into Curve


Curve will automatically detect the P2P targets and the profiling targets, & offer to let you save them and continue with the curve workflow.
At this point, you just need to click "Continue with P2P" in order to enter your G7 data into Curve.

Virtual Press Run

VPR dialog window in Curve2

When it is time to create your press profile, you would:

  • Click on the VPR button in Curve
  • Choose the run with the curves you wish to apply to the profiling target (usually the last run)
  • Choose the profiling target measurement you made (either an IT8 or a HC2052)
  • Click Curve & Export

VPR will apply the curves to the measurement data of the press profiling target. You can then take this "curved" measurement and build a profile using your normal profiling engine. This profile will accurately reflect the condition your press is in as a result of being curved to the G7 method!
