You can change the settings of the selected color pre-set for the current job only. You cannot save your changes. You have to use the Settings Editor of the printer to create new color pre-sets.
If you change a setting of the selected color pre-set in this dialog, the name changes into [Custom]. You can use the custom color pre-set only for the current job. You cannot save your changes.
Print in [Color] or [Black & white].
These settings define the halftone screening for images, text/lines and graphics. You are advised to use the default option.
[Fine]
[Normal]
[Error diffusion]
Error diffusion is a type of halftoning in which the quantization residual is distributed to neighboring pixels that have not yet been processed. Its main use is to convert a multi-level image into a binary image, though it has other applications.
A spot color in a document is defined by a color name and an alternative color specification. The printer 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.
[Yes] (default)
Match the document colors with the color library of the printer
[No]
Use the alternative color specification
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.
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].
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.
Enable this option to make sure that a black type always overprints colored objects behind it.
For most objects, color profiles and rendering intents are embedded in the document. However, objects with a color specification in DeviceRGB or DeviceCMYK have no embedded color profile and rendering intent. In this dialog, you can specify an input color profile and rendering intent for these objects. [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.
[DeviceRGB / Embedded profiles]
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.
[DeviceCMYK / Embedded profiles]
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.
For most objects, color profiles and rendering intents are embedded in the document. However, objects with a color specification in DeviceRGB or DeviceCMYK have no embedded color profile and rendering intent. In this dialog, you can specify an input color profile and rendering intent for these objects. 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] and [Use embedded profiles and DeviceCMYK settings]
For most objects, color profiles and rendering intents are embedded in the document. Use these profiles and rendering intents for these objects. However, objects with a color specification in DeviceRGB or DeviceCMYK have no embedded color profile and rendering intent. Use the DeviceRGB settings or DeviceCMYK settings in this dialog for the objects that have no embedded color profile and rendering intent.
[Overrule embedded profiles with DeviceRGB settings] and [Overrule embedded profiles with DeviceCMYK settings]
For most objects, color profiles and rendering intents are embedded in the document. Select this setting to ignore these profiles and rendering intents. Use the DeviceRGB settings or DeviceCMYK settings in this dialog for all objects.
