Printer linearization

A printer linearization ensures that printed colors respond in a controlled, linear way to the input values of the source file, which improves color accuracy, stabilizes the printing process, and makes results more predictable.

While linearizations are often applied at the printer front end, you can also include them in your SmartProfiler project. Below, you'll learn how to:

• create a new linearization
• apply an existing linearization
• proceed without linearization, for example if one is already applied at the printer front end

Note: If you're unsure whether a linearization is necessary, it's generally recommended to include one. Even if the printer already applies a linearization, having an additional one in SmartProfiler typically does not cause issues.

Create a new linearization profile

To create a new linearization, you'll need to print and measure a test chart.

Alternatively, you can add an existing measurement for your printing process by clicking the "Import" button and selecting the file in the system browser.

SmartProfiler then automatically calculates the linearization curves and the ink cut – the maximum ink value per channel beyond which the printer cannot further increase the tonal value. Both the curves and the ink cut values are displayed in the interface, allowing you to review and adjust them as needed.

You can change values by typing directly into the box or using the up/down arrows. The gradation curves in the graph on the right side update on-the-fly.

In the final SmartProfiler step ("Finalize & Publish"), the linearization is later automatically saved as an MXN profile and can be found under Resources > MX Profiles. It can then also be used in other SmartProfiler projects.

Note: If you modify the linearization of an already published project, it will be saved under the same name, overwriting the previous version. Please keep this in mind if the linearization is also used in other SmartProfiler projects.

When opening the conversion template of the SmartProfiler project under Resources > Conversion, you’ll see that the MXN linearization profile is applied in the last conversion step.

Use an existing linearization

To apply an existing linearization, select the linearization profile from the dropdown menu.

Use no linearization

If you do not want to include a linearization, for example because one is applied directly at the printer front end, proceed with the default setting "No Linearization".
