ZXC Print Shares Tips on Solving Graininess Issues When Using EFI Linearization

HUIZHOU, China - Nov. 17, 2025 - PRLog -- ZXC Print, a professional printing company offering high-quality book printing (https://www.zxcprint.com/products/book-printing/) and commercial printing services, recently shared expert insights on reducing graininess when using EFI Fiery XF or Fiery ProServer workflows. The company highlights several key adjustments that can help printers achieve smoother color transitions and superior print quality.

1. Increase Precision During Linearization

ZXC Print recommends setting a higher precision level during the linearization process. This adjustment improves tonal accuracy, leading to smoother gradients and less visible graininess—especially in lighter image areas.

2. Understand the Difference Between EFI and OEM Drivers

At the same resolution, EFI output may appear slightly grainier than prints made with OEM drivers. According to ZXC Print, this is a normal result of EFI's unique halftone algorithm and color management process, not a technical flaw.

3. Adjust Halftone (HT) Mode

The company suggests experimenting with Halftone (HT) modes to find the optimal setting. For instance, 8-color printing provides finer, smoother details, while 4-color printing may show more noticeable dots.

4. Modify Resolution Settings

Increasing print resolution—from 720 DPI to a higher value—can effectively reduce grain effects. However, ZXC Print reminds users that higher resolution increases ink usage and printing time, so balancing quality and efficiency is important.

5. Fine-Tune Other Print Parameters

Users can also optimize print smoothness by adjusting dithering patterns, ICC profiles, and resolution settings. These fine-tuned parameters help achieve a consistent, high-quality finish.

6. Additional Optimization Tips

ZXC Print emphasizes several key best practices for achieving optimal EFI results:

• Match your media profile with the correct substrate or paper type.
• Perform regular printer calibration for color stability.
• Use high-quality ICC profiles for EFI Fiery XF or Fiery ProServer workflows.
• Maintain a stable print environment—temperature and humidity affect ink performance and color consistency.

Achieving Professional Results

By combining these techniques—particularly fine-tuning linearization and halftone settings—print operators can significantly reduce graininess and enhance visual smoothness across all EFI-based print jobs.
