How to Solve Graininess Issues When Using EFI Linearization
Increase Precision During Linearization
When performing linearization, try setting a higher precision level. This helps achieve smoother gradients and reduces visible graininess in printed results.
Understand the Difference Between EFI and OEM Drivers
At the same resolution, if you’re used to printing with the original OEM driver, EFI output may appear slightly grainier. This is a known difference due to EFI’s halftone algorithm and color management approach.
Adjust Halftone (HT) Mode
Switching the HT mode can make a noticeable difference. For example, 8-color printing delivers finer and smoother details, while 4-color printing tends to show more visible dots and a rougher texture.
Modify the Resolution Settings
Increasing the print resolution—for example, from 720 DPI to a higher value—can reduce the grain effect and produce cleaner results. However, this comes at the cost of higher ink consumption and potentially slower printing speed, so balance is key.
Fine-Tune Other Print Parameters
Experiment with different parameters in the print setup, such as resolution, dithering pattern, and color profile. Adjusting these settings can help you find the best compromise between quality, speed, and ink usage.
Additional Tips for Optimization
Make sure your media profile is correctly matched to the paper or substrate being used.
Regularly calibrate your printer to ensure color stability.
Use high-quality ICC profiles for EFI Fiery XF or Fiery ProServer workflows.
Maintain a stable environment (temperature and humidity) to prevent inconsistent ink behavior.
By combining these adjustments—especially fine-tuning the linearization and halftone settings—you can significantly improve print smoothness and minimize visible graininess when using EFI printing systems.
