Colour settings

Introduction

You can create color pre-sets for your document types, workflows or color applications with the settings editor on the printer controller. You can use the new color pre-sets in the print dialog.

[Color preset]

A color pre-set is a collection of color and quality settings that matches a specific document type, workflow or color application. A color pre-set is defined at the printer controller and available at the printer driver. Use the settings editor of the printer controller to create new color pre-sets. Use this setting to print with an optimal print quality.

[Custom color presets]

Use the [Custom color presets] to change the color settings of the selected color pre-set for the current job only. When you click [Custom color presets], the [Custom color presets] window opens. Use the settings editor of the printer controller to create new color pre-sets.

[Custom color pre-sets] window

The printer controller uses the embedded color profiles and rendering intents of the objects in the document. Objects with a color specification in DeviceRGB or DeviceCMYK have no embedded color profile and rendering intent. For these objects a default input color profile and rendering intent are defined by the printer driver for optimal print quality.

Setting

Description

[Name]

The name of the color pre-set. The default names of the color pre-sets are the following.

  • Black and white

  • Office documents

  • Photographic content

If you change a setting in the printer driver, the [Name] changes into [Custom color pre-sets].

[Description]

The [Description] of the color pre-sets informs you when you can apply the color pre-set.

Define the [Color] settings

Setting

Description

[Color]

Print in [Color] or [Black & white].

[Halftone for graphics and images]

Defines the halftone screening for graphics and images. You are advised to use the default option.

[Halftone for text]

Defines the halftone screening for text. You are advised to use the default option.

[Spot color matching]

A spot color in a document is defined by a color name and an alternative color specification. The printer controller uses the color name to match with the closest color of the printer. The colors of the printer are defined in color libraries on the printer controller.

  • Select [No] to use the alternative color specification

  • Select [Yes] (default) to match the document colors with the color library of the printer controller

[Color mapping group]

You can select a color mapping group to apply color transformations to the image colors. Color mapping re-maps the image values to be suitable for printing purposes.

You can select a color mapping group for RGB, CMYK or spot color to re-map the images to a spot color.

[PDF/X output intent]

The output intent is defined by a profile. The output intent represents what the author had in mind for the final output of the document.

For example, the author creates the document in an RGB color space, but the document must be printed on a SWOP press. In this case, you can select a SWOP profile as the [PDF/X output intent].

[PDF overprint simulation]

By default, when you print opaque, overlapping colors, the top colour knocks out the area underneath. Overprinting prevents knockouts and makes the topmost overlapping printing ink appear transparent in relation to the underlying ink.

This setting is used by Adobe Acrobat.

This setting is not available for all printer models.

[Force black overprint]

Enable this option to make sure that a black type always overprints colored objects behind it.

Define the [DeviceRGB / Embedded profiles] settings

Setting

Description

[Input profile]

[Input profile] defines a reference color workspace for the color data of the objects in the document. An [Input profile] is used to define colors in a device independent way.

The following DeviceRGB options are available.

  • sRGB

    Use this input profile in Windows Office or similar environments.

  • [None]

    Use this option to use the printer device colors.

  • AdobeRGB1998

    Use this input profile if the documents are prepared for use on high chroma devices.

  • AppleRGB

    Use this input profile if the documents are prepared in Apple environments.

  • ColorMatchRGB

    Use this input profile if the color data was created in a very big color workspace. Make sure you use [Perceptual] as [Rendering intent] to avoid that color areas clip and to preserve details.

[Rendering intent]

The [Rendering intent] defines the color conversion strategy that is needed because colour gamuts differ per device (monitors, printers). The required print quality determines the rendering intent you need for an optimal color conversion.

The following options are available.

  • [Absolute colorimetric]

    The exact colors that are within the gamut of the printer are kept, even the colors near the white point. Prints white areas with a light background. The out-of gamut colors are mapped to colors on the border of the printer gamut. Details, continuity and contrast in colored areas can be lost due to the mapping.

    This setting is useful to map spot colors and it is useful to make proof prints.

  • [Relative colorimetric]

    The exact colors that are within the gamut of the printer are kept, except the colors near the white point. Prints white areas perfectly white (no toner or ink is used). The out-of gamut colors are mapped to colors on the border of the printer gamut. Details, continuity and contrast in colored areas can be lost due to the mapping.

    This setting is useful to make proof prints.

  • [Perceptual] (default)

    All colors are converted relative to each other, preserving details, continuity and contrast. The out-of gamut colors are mapped to colors within the printer gamut. Prints white areas perfectly white (no toner or ink is used).

    This setting is useful to print images or photos.

  • [Saturation]

    All colors are converted relative to each other, preserving saturated colors and pure colors as much as possible. The out-of gamut colors are mapped to colors within the printer gamut. Prints white areas perfectly white (no toner or ink is used).

    This setting is useful for presentations, line-art, histograms, artist impressions, business graphics, et cetera.

[Use embedded profiles and DeviceRGB settings]

Embedded color profiles are used. [Input profile] and [Rendering intent] settings are used for objects in documents with DeviceRGB color specification.

[Overrule embedded profiles with DeviceRGB settings]

Embedded color profiles are overruled with the [Input profile] and [Rendering intent] settings. [Input profile] and [Rendering intent] settings are used for objects in documents with DeviceRGB color specification.

Define the [DeviceCMYK / Embedded profiles] settings

Setting

Description

[Input profile]

[Input profile] defines a reference color workspace for the color data of the objects in the document. An [Input profile] is used to define colors in a device independent way.

The DeviceCMYK profiles list contains color profiles as defined by formal standardization organizations. Select the same CMYK color profile that was used to create the document. Select no color profile to leave the DeviceCMYK color specification as is.

[Rendering intent]

The [Rendering intent] defines the color conversion strategy that is needed because colour gamuts differ per device (monitors, printers). The required print quality determines the rendering intent you need for an optimal color conversion.

The following options are available.

  • [Absolute colorimetric]

    The exact colors that are within the gamut of the printer are kept, even the colors near the white point. Prints white areas with a light background. The out-of gamut colors are mapped to colors on the border of the printer gamut. Details, continuity and contrast in colored areas can be lost due to the mapping.

[Use embedded profiles and DeviceCMYK settings]

Embedded color profiles are used. [Input profile] and [Rendering intent] settings are used for objects in documents with DeviceCMYK color specification.

[Overrule embedded profiles with DeviceCMYK settings]

Embedded color profiles are overruled with the [Input profile] and [Rendering intent] settings. [Input profile] and [Rendering intent] settings are used for objects in documents with DeviceCMYK color specification.
