Example of a OneRun target, containing the patches of the IT8 target with the P2P51

The OneRun target, in combination with Curve4’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 Curve 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 P2P51 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. Measuring this target into Curve4, the Calibration module will automatically recognize the P2P51 patches and use them for calibration. The entire measurement can also be exported from the software and used for other purposes, such a profile-building and VPR. 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:

Other OneRun targets incorporating alternate profiling targets will also be available.


Currently we have OneRun targets which incorporate:

  • The P2P51 target and the IT8 target (most popular for press profiling)
  • The P2P51 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,

Print image


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

Measure OneRun target

Measure the OneRun target in Curve4.

Export the measurement from Curve4


Curve will automatically detect the P2P target and use it for calibration.

Virtual Press Run

OneRun target can be used in VPR.

To use the OneRun target in VPR:

  • Choose the run with the curves you wish to apply to the profiling target (usually the last run)
  • Click on the VPR tab
  • Choose the exported OneRun measurement you saved earlier)
  • 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!
