Colour settings

Introduction

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

[Colour preset]

A colour pre-set is a collection of colour and quality settings that matches a specific document type, workflow or colour application. A colour 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 colour pre-sets. Use this setting to print with an optimal print quality.

[Custom colour presets]

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

[Custom colour pre-sets] window

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

Setting	Description
[Name]	The name of the colour pre-set. The default names of the colour 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 colour pre-sets].
[Description]	The [Description] of the colour pre-sets informs you when you can apply the colour pre-set.

Define the [Colour] settings

Setting	Description
[Colour]	Print in [Colour] 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 colour matching]	A spot colour in a document is defined by a colour name and an alternative colour specification. The printer controller uses the colour name to match with the closest colour of the printer. The colours of the printer are defined in colour libraries on the printer controller. Select [No] to use the alternative colour specification Select [Yes] (default) to match the document colours with the colour library of the printer controller
[Colour mapping group]	You can select a colour mapping group to apply colour transformations to the image colours. Colour mapping re-maps the image values to be suitable for printing purposes. You can select a colour mapping group for RGB, CMYK or spot colour to re-map the images to a spot colour.
[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 colour 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 colours, 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 coloured objects behind it.

Define the [DeviceRGB / Embedded profiles] settings

Setting	Description
[Input profile]	[Input profile] defines a reference colour workspace for the colour data of the objects in the document. An [Input profile] is used to define colours 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 colours. 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 colour data was created in a very big colour workspace. Make sure you use [Perceptual] as [Rendering intent] to avoid that colour areas clip and to preserve details.
[Rendering intent]	The [Rendering intent] defines the colour 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 colour conversion. The following options are available. [Absolute colorimetric] The exact colours that are within the gamut of the printer are kept, even the colours near the white point. Prints white areas with a light background. The out-of gamut colours are mapped to colours on the border of the printer gamut. Details, continuity and contrast in coloured areas can be lost due to the mapping. This setting is useful to map spot colours and it is useful to make proof prints. [Relative colorimetric] The exact colours that are within the gamut of the printer are kept, except the colours near the white point. Prints white areas perfectly white (no toner or ink is used). The out-of gamut colours are mapped to colours on the border of the printer gamut. Details, continuity and contrast in coloured areas can be lost due to the mapping. This setting is useful to make proof prints. [Perceptual] (default) All colours are converted relative to each other, preserving details, continuity and contrast. The out-of gamut colours are mapped to colours 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 colours are converted relative to each other, preserving saturated colours and pure colours as much as possible. The out-of gamut colours are mapped to colours 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 colour profiles are used. [Input profile] and [Rendering intent] settings are used for objects in documents with DeviceRGB colour specification.
[Overrule embedded profiles with DeviceRGB settings]	Embedded colour 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 colour specification.

Define the [DeviceCMYK / Embedded profiles] settings

Setting	Description
[Input profile]	[Input profile] defines a reference colour workspace for the colour data of the objects in the document. An [Input profile] is used to define colours in a device independent way. The DeviceCMYK profiles list contains colour profiles as defined by formal standardisation organisations. Select the same CMYK colour profile that was used to create the document. Select no colour profile to leave the DeviceCMYK colour specification as is.
[Rendering intent]	The [Rendering intent] defines the colour 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 colour conversion. The following options are available. [Absolute colorimetric] The exact colours that are within the gamut of the printer are kept, even the colours near the white point. Prints white areas with a light background. The out-of gamut colours are mapped to colours on the border of the printer gamut. Details, continuity and contrast in coloured areas can be lost due to the mapping. This setting is useful to map spot colours and it is useful to make proof prints. [Relative colorimetric] The exact colours that are within the gamut of the printer are kept, except the colours near the white point. Prints white areas perfectly white (no toner or ink is used). The out-of gamut colours are mapped to colours on the border of the printer gamut. Details, continuity and contrast in coloured areas can be lost due to the mapping.

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