Layer Tab

Select to enable a color plane on this layer, the flood, set a choke value using the arrows, and set a synonym for the color plane name.

Use X Shift (horizontal) and Y Shift (vertical) to fix plane alignment issues on 8-bit devices (per pixel).

Note: This choke setting is used when underbase white is created in the design application. If underbase white is generated automatically in the queue, use the Processing Options tab.

Note: If choke is set both here and in the Halftones tab, and the Halftones tab setting overrides this tab setting.

White Ink Only Print Modes

Select to use documents with more than one page as layers. Select a page number.

Note: You cannot mix pages when some have underbase data and others do not. If the underbase data on the layers is mixed (for example, a custom white channel), proceed as follows:

• All pages must have underbase data (and use a print mode that does not generate the underbase in Processing Options)
• None of the pages must have underbase data (and the print mode generates one as per the Processing Options)
• Multi-page Documents

Select an option for the layer:

• No mirror
• Mirror horizontally
• Mirror vertically

Note: If you have set rotation on import, the output will first rotate and then mirror (useful for double-sided signs, printed using layers).

Select amount of scaling on X, Y planes.

Note: If scaling is used with copy groups, gaps will appear. For best seamless results, scale to 100% and use hardware options.

Choose from the following:

• None
• Underbase - this creates an underbase for the entire bounding box
• Highlight
• Underbase and Highlight - this creates a single-pass highlight and underbase by distributing the white ink
• Coverage underbase - this creates an underbase only where it is needed
  • White is distributed based on the grayscale values of the image. Darker values result in less white ink.

Note: Depending on the layer options chosen, values below may not be available.

Underbase Strength and Manual Curve

If white is generated automatically, use the choke value in this tab. If white is generated in the graphic, use the choke in the Layer Profile tab.

Use the following options:

• Use KnockMeBlackOut: When printing garments, use this filter to remove unnecessary black ink on a black garment.
• Clean black: Turns areas close to black to black. Apply this before KnockMeBlackOut to remove more area.
• Color boost blend: Increases the amount of color ink printed for vibrancy.
  Note: Only applicable with Flatten selected.
• Color boost graphics: Increases the amount of color ink printed for vibrancy. Positive values are lighter and negative values are darker due to gamma correction.
  Note: Only applicable with Flatten selected.
• Use KnockMeWhiteOut: When printing garments, use this filter to remove unnecessary white ink on a white garment.
• Flatten: Recommended for bitmaps with transparency, flattens color data according to transparency information.

Use the following options:

• None
• Apply: Set the maximum ink, choke, whether to invert the alpha layer color, and whether to treat all semi-transparent color as opaque.

Find the option and use the drop-down list in the Value column to make changes.

Note: Options vary by device.

Select a color value in the drop-down list below the graph, then select one of the options:

• By levels
  • Use the sliders to adjust values.
• By density
  • Use the arrows to adjust values or manually adjust using the graph (click and drag to adjust).
  • Click Calculate Density to view calculations by density or percentage.
    • Enable Extended densities for more detailed control over the transfer curve.

Resetting a Queue to Defaults

Select to override input profile. If selected, use the drop-down list to select a profile set to use.

• Original: Reset any changes to the input profiles.
• Enhanced: Use (missing or bad snippet)'s enhanced input profiles (recommended).
• Get from print mode: Use the input profiles indicated in the print mode.
• Custom: Choose the individual input profiles.

Click the drop-down arrow to display the Rendering dialog.

• Select the first and second rendering intent using the drop-down lists.
• Use the slider or arrows to set the merge (blending between rendering intents) and chroma (to make colors look stronger or weaker).
• Select exceptions (when selected, the activity of the rendering intent is blocked for that aspect), and use the slider or arrows to set the range (the tolerance within which an input color value qualifies for a given exception; increasing the tolerance causes more colors to be affected by exceptions).

The rendering intent determines how these colors are mapped from the input profile to the output profile.

Rendering Intents

Rendering Dialog

Select to override output profile. If selected, use the ellipsis button to select a profile set to use. The ICM Source Selector dialog appears.

• Click to select from printer profiles, Windows defined profiles, or to browse from current location.

Click the arrow drop-down to launch the Device Link dialog. Use the ellipsis button to open the ICM Source Selector to make selections.

• To remove a selection, click the X.

For each ink, set the frequency (measured in LPI; the resolution of the dot shape), angle (to ensure consistency in production), and shape for each ink (depending on the detail desired).

Set the choke, increase the value. To set the spread, decrease the value.

Click to view jitter factor vs. halftone level graph. Modify halftone screens to improve print quality by clicking and dragging to adjust. Jitter introduces miniscule distortions to the dot shape making the overall pattern within the dots less discernible.

Save and Load a preset as a .jitt,

Halftone Level: The increasing size of a halftone cell, from 0% tint (empty) to 100% tint (completely filled in cell).

Jitter Factor: The amount of randomness applied within any given range of the Halftone Level. By default, there is zero jitter.

To distort a pattern, select a suitable range and increase the jitter for that range. Increasing above 1.0 can cause the halftone to lose structure.

Ranges:

• Highlights (0-10%)
• Midtones (10-90%)
• Shadows (90-100%)

Group four normal halftone cells into one, increasing the number of gray levels without increasing the frequency of the halftone.

Select to enable variable dot profiling. When disabled, ink output volume increases.

Note: If halftones are enabled or disabled, this feature interacts differently. Variable Dot Setup is device dependent.

The Ink Setup value on the Printer Options tab directly correlates with these settings.

With laser printers, the dot size and hole size are adjustable. For more information, see Color Adjust.

Enabled Advanced Screening to ensure channel information is separated to unique areas when placing dots (so no information is lost or covered by dots of other channels).

Note: Only available when Print Mode Creation enabled.

When enabled, control the type of holes created in output to save ink. Set a frequency and angle. This effect is applied to all channels.

Halftones can only be set here, however other controls can be found in Color Adjust.

To apply a choke to ink removal, set it in Layer Profile tab rather than Processing Options.

Note: To ensure color vibrancy on transparent areas, set color boost (Queue > Setup color boost).

Measured in Lines Per Inch (LPI), the frequency is the number of halftone cells per inch.

Set the angle to rotate the cell on the page. Some angles are more visible.

Dots can be a wide variety of shapes but Inverted Round and Line are most typical. Selection depends on your opinion of which one produces the best detail.

Enable to vary the hole size. then use the Adjust holes slider to control the size of the holes. Hole size increases as transparency increases.

Note: When disabled, space is uniform over the entire image and hole size controls ink removal.

Tip: When enabled, and hole size is set to 255, opaque areas do not have holes.
