How to Solve Graininess Issues When Using EFI Linearization

Graininess in printed images can be frustrating—especially when you’re aiming for smooth gradients and professional-quality output. If you’re using EFI Fiery XF or Fiery ProServer, you may have noticed that some prints appear slightly grainy even at high resolutions. Fortunately, with a few adjustments to your workflow, you can achieve much smoother and more consistent results.

1. Increase Precision During Linearization

When performing linearization, always select a higher precision level. This ensures finer tonal control and helps reduce visible graininess, particularly in light or gradient areas.

2. Understand the Difference Between EFI and OEM Drivers

At identical resolutions, EFI prints may appear a bit grainier than those produced with OEM drivers. This is due to the unique halftone algorithm and color management used by EFI. Understanding these differences allows you to make better adjustments for smoother output.

3. Adjust Halftone (HT) Mode

Experimenting with Halftone (HT) modes can make a significant difference:

• 8-color printing delivers smoother details and minimizes visible dots.

• 4-color printing tends to show more texture and less refined gradients.Choose the HT mode that best balances detail, speed, and ink efficiency for your project.

4. Modify the Resolution Settings

Increasing the print resolution—for example, from 720 DPI to a higher setting—can effectively reduce graininess. Keep in mind that this also increases ink consumption and print time, so finding the right balance between quality and productivity is essential.

5. Fine-Tune Other Print Parameters

Don’t overlook the impact of other settings. Adjust resolution, dithering patterns, and ICC profiles to optimize your results. Even small tweaks in these parameters can greatly enhance print smoothness and consistency.

6. Additional Optimization Tips

• Ensure your media profile matches the paper or substrate you’re using.

• Regularly calibrate your printer to maintain consistent color output.

• Use high-quality ICC profiles for EFI Fiery XF or Fiery ProServer.

• Maintain a stable printing environment—temperature and humidity can affect ink behavior and color accuracy.

By combining these strategies—especially fine-tuning the linearization and halftone settings—you can dramatically improve gradient smoothness, minimize visible graininess, and produce vibrant, professional results.

If you’re working on projects that demand top-tier quality, such as book printing or premium packaging, optimizing your EFI workflow can make a real difference.
