When defining a device condition, you can add a spot ink and select a curve channel for the ink. You can also add spot inks to an existing device condition. 

Note: The spot ink named "Default" is the default curve channel that is used for undeclared spot inks.
  1. In the Device Condition Properties dialog box, in the Spot Inks section, click the Add button .
  2. Double-click the Color column and choose a suitable color (for visual recognition only).
  3. Click the Name  column and enter the name of the spot ink, such as PANTONE 236 C.
    It's important that you enter the spot ink name exactly as its separation is named in the design file, or Prinergy will not apply the correct channel.
  4. Do one of the following:
    • Click the Curve column and choose a curve channel to be used for the spot ink
    • To create a custom curve channel, select Custom. The custom curve is identical to the curve channel previously selected for the spot ink and can be adjusted without affecting other curve channels
  5. Click OK. A curve channel is added for the spot ink.
  6. Measure the tonal response of the spot ink using a tint ramp chart. If you don't measure the spot ink, a linear curve is generated and you can adjust it following instructions in Step 7.

  7. Define the target response for the spot ink.

  1. Perform one of these actions:
    1. For spot inks in a PCO, click the Simulation icon .
    2. For spot inks in an SCO, click the Conversion icon .
    3. For spot inks in a print calibration curve, click the Calibration icon .
  2. Click the Spot Inks tab.
  3. Select the target as follows:
    • If you have measured the SCTV response of spot inks, select Target value Linear (selected automatically). This sets the Curves Method to Linear SCTV.
    • To calibrate spot inks to an EDA or TVI target response, select any Target value other than Linear or None. This sets the curve method to Tonal Match.
    • To generate linear curves that can be manually adjusted, select Target value None. This sets the curve method to Manual Adjustments Only.
  4. Click OK

Note:  For a spot ink whose response has not been measured, the following settings always apply:

  • Target: None
  • Curves Method: Manual Adjustments Only

You can view the Curves Method for each spot ink by clicking Details in the Simulation, Conversion or Calibration definition dialog.
