Job Gradation Curve Preset in the Print Environment

How to Assign a Job Gradation Curve Preset to a Print Environment

Applies to: Ergosoft RIP 17.6.2.0282 and later · JobComposer, HotFolder · all printer drivers

Use this when:

  • You select the same Job Gradation Curve preset manually in every new job
  • Some jobs are printed without the curve, and the colors are not consistent
  • A media or ink combination always needs the same channel correction

Question

How do I apply a Job Gradation Curve preset automatically to every new job that uses a specific Print Environment?

Steps

Create the Preset

  1. Open a job with the Print Environment you want to use.
  2. Check that no image is selected in the job.
  3. Go to Job Properties & Actions > Job Gradation Curves.
  4. Create the curve and click the green + button to save it as a preset.

Result: The preset is available in the preset list.

For details on editing curves, see Job Gradation Curves.

Assign the Preset to the Print Environment

  1. Open the Print Environment settings.
  2. Go to the Extras tab.
  3. In Job Gradation Curves, select the preset.
  4. Save the Print Environment.

Result: The Print Environment contains the preset.

Tip: To see the effect of the curve before printing, use Job Preflight in Device TIFF mode. This is available since Ergosoft RIP 17.7.2.0465.

Apply the Changes

  • The preset applies only to jobs that you create after you assign it. Existing jobs keep their settings.
  • HotFolders that use this Print Environment also apply the preset.

FAQ

Can I change the curve for a single job?
Yes. The preset is only preselected. Select a different preset in Job Properties & Actions > Job Gradation Curves.

When do I use Job Gradation Curves and when do I use Tune?
Job Gradation Curves change the printer output channels for the whole job. Use them for a correction that always applies to a media or ink combination. Image Properties > Tune changes one image and has a live preview. Use Tune for a single design.

Are Job Gradation Curves the same as Photoshop Curves?
No. The handling is similar, but Adobe Photoshop curves work in the image color space. Job Gradation Curves work in the printer output color space, so the values cannot be compared.
