Proper management of white ink is essential for achieving the best visual quality and fabric feel when printing on dark or colored textiles. Dynamic White and Highlight White are two key functions that allow fine control over white ink behavior to optimize both opacity and print softness.


TABLE OF CONTENTS


1. Dynamic White

Dynamic White adjusts the amount of white ink automatically based on the total color ink coverage of the printed design.


Purpose:

  • To reduce white ink where it's unnecessary (dark colors with high ink coverage).

  • To maintain proper opacity where needed (light colors or low ink coverage).


How It Works:

  • Low Ink Coverage: You specify the amount of white to apply when the total color ink usage is low.

  • High Ink Coverage (at Ink Limit): You specify a reduced white level because heavy dark colors naturally hide the fabric background better.

This saves white ink, improves print flexibility, and can enhance the fabric’s feel by reducing unnecessary thickness.


Setup Example:

  • Base White at 80%

  • Dynamic setting at 60-40% (200%):

    • When color ink is low → use closer to 80% white.

    • When color ink is high → white ink reduces proportionally down to 40%.


You can fine-tune it by running an Ink Limit Test in the Calibration Wizard:

  • Print the test page.

  • Evaluate color vibrancy and background opacity.

  • Adjust Dynamic White settings accordingly.

Dynamic 60 - 40 (at 200%). The more intense and darker the color, the more color ink and the less white ink it'll use.
Same as before, but adding Highlight 50% at Amplitude 10%.
Same, with Hightlight 50% at Amplitude 25%.



2. Highlight White

Highlight White provides an additional boost of white ink selectively for specific areas needing stronger visibility, such as:

  • Small text

  • Logos

  • Detailed graphic elements


Purpose:

  • To enhance white parts without flooding the entire print with extra ink.

  • To keep control over ink load, ensuring good opacity without affecting overall softness.


How It Works:

  • When you cut white ink at a base level (e.g., 60%), there is an unused percentage (100% - 60% = 40%).

  • Highlight White allows you to allocate a percentage of that unused capacity to enhance bright areas.


Example:

  • Base White cut at 60%.

  • Highlight White set at 50% → Uses 50% of remaining 40% = 20% extra white.

  • Result: 80% total white where needed (60% base + 20% highlight).


Key Parameter:

  • Amplitude:

    • Defines the tolerance for how much color variation will be included in the Highlight White effect.

    • Low amplitude = affects only pure whites.

    • High amplitude = affects a broader range of light tones.

Normal white channel, Flat, at 60%. You can see that white is homogenous, all pixels have the same amount of white.
Same configuration, Flat 60%, but with Highlight 50% - Amplitude 10%. On maximum white, we're using 50% of remaining 40%, which is 20%. In the end, we have 60% white on most colors and 80% (60+20) on white parts.
Same configuration, Flat60%, with Highlight 50% and amplitude 25%. You can see how there are darker parts on the suit with higher level of white ink.



3. Practical Examples

Setup
Description
Flat White 60% only
Uniform white level across all the design.
Flat 60% + Highlight 50% (Amplitude 10%)
Stronger white only on maximum white zones (small details, logos).
Flat 60% + Highlight 50% (Amplitude 25%)
Stronger white effect applied to a broader range of light colors.
Dynamic 60–40 at 200%
Less white used in dark areas, more in light areas.
Dynamic 60–40 with Highlight 50% (Amplitude 10%-25%)
Smart combination: reduced ink on dark areas, boosted white on key highlights.



4. Best Practices

  • Use White Chart Tests:
    Before finalizing your settings, always print a White Chart using Step 1 of the Calibration Wizard to visually assess:

    • Base white appearance.

    • Highlight white strength.

    • Handle (softness) of the print.

  • Combine Dynamic and Highlight Wisely:

    • Use Dynamic White to optimize ink load across the whole design.

    • Use Highlight White to bring out important details without compromising the fabric's flexibility.

  • Test Different Amplitudes:
    Adjust amplitude depending on the type of design:

    • For clean graphics (text, logos) → low amplitude.

    • For artistic or soft gradients → higher amplitude.

  • Check Handle Feel:
    After applying these settings, touch the printed fabric to verify that the feel is not overly rigid due to excessive ink.
