XMF includes a unique colour conversion engine called [Fujifilm Enhanced] mode. In [Fujifilm Enhanced] mode, Fujifilm's colour processing technology is used for various conversion functions, such as unique rendering intents, the ink limit function, and black point compensation.
Also, [Adobe Basic] mode is provided as an option for supporting jobs and templates for which colour conversion was performed using Adobe's ACE (Adobe Color Engine) engine in a previous version.
You can perform colour conversion in 3 stages with XMF colour conversion, for the "Document Colour Space", "Press Colour Space" and "Proofer Colour Space".
In the 1st stage of colour conversion, the input colour space is converted to the "document colour space". This converts the input data to the standard colour space.
Next, in the 2nd stage of colour conversion, colour conversion is performed to match the "press colour space", which is the colour space of the actual output device.
Further, when outputting to a proofing device, colour conversion is performed to match the "proofer colour space" in the 3rd stage of colour conversion.
Performing colour conversion in 3 stages enables more precise colour reproduction regardless of the input data type or output device.
The 1st stage of colour conversion (conversion to the document colour space) is set for jobs, sections or pages in [Colour] pane of the job settings.
The 2nd stage of colour conversion (conversion to the press colour space) is configured in the corresponding setting pane of the workflow item ([Press], [Digital Press], [Jet Press]/[J Press], [Jet Press F]/[J Press F], [Jet Press R] or [Jet Press W]/[J Press W]).
The 3rd stage of colour conversion (conversion to the proofer colour space) is configured in the corresponding setting pane of the workflow item ([RIP Proof] or [ROOM Proof]).
When outputting PDF with [PDF Export], colour conversion for PDF output that is separate from the press colour space is performed as the 2nd stage of colour conversion.
Also, when outputting to [RIP Proof], conversion can be performed directly to the proofer colour space in the 3rd stage, without converting to the press colour space in the 2nd stage.
In [Colour] pane, you can configure the settings for converting the colour space of the input data (input colour space) to the document colour space as the 1st stage of colour conversion.
In [Fujifilm Enhanced] mode, the colour conversion to the document colour space is performed for jobs, sections, and pages. You can configure various colour conversion settings by individual image, line art, text, and smooth shades object for the input colour space of CMYK, RGB, and Grey.

13 |
Preserve Pure Colour |

In [Adobe Basic] mode, colour conversion is performed using Adobe's ACE (Adobe Color Engine) engine.
It is appropriate for performing the same colour conversion as Adobe applications such as Photoshop.
Colour conversion cannot be performed for individual object types in [Adobe Basic] mode.
Colour conversion cannot be performed for individual sections or pages in [Adobe Basic] mode.
When [Fujifilm Enhanced] mode is selected, colour conversion is performed using XMF's unique colour engine.
*1Rendering intent is a method for replacing colours referenced when colour space is converted. In XMF's colour conversion ([Fujifilm Enhanced] mode), the following rendering intents are defined by ICC profiles. The settable rendering intents vary according to the colour engine and the colour space or colour type to convert.
Saturation: Vivid colour reproduction is given priority over accurate colour reproduction in conversion. This setting is appropriate for objects such as graphs and diagrams that require use of bright colours.
Perceptual: Visual reproduction of colour space is given priority in conversion to present a natural look. This setting is appropriate for objects such as photo images which include lots of colours outside the gamut.
Relative Colorimetric: Areas with the greatest highlighting for each colour space before/after colour conversion are compared, and all colours are converted with the colour values shifted based on the difference only. Colours outside the gamut are converted to approximate colours which can be reproduced within the colour space after conversion. Compared to [Perceptual], original colours for more images can be reproduced.
Absolute Colorimetric: Colours inside the gamut are not converted, but colours outside the gamut are clipped. This setting is appropriate for checking accurate colours such as colour samples because reproducible colours are reproduced accurately.
Fujifilm Original Rendering Intents
For [CMYK]
Fujifilm Perceptual: Colours near the gamut boundary are converted with priority in tone scale to consecutive colours with colours outside the gamut, even if they are colours inside the gamut.
Fujifilm Colorimetric: Colours inside the gamut are converted to colours that match each other before/after colour conversion, but colours outside the gamut are mapped on the gamut boundary.
For [RGB]
Fujifilm Photographic: Select to prioritise compatibility with data for which colour conversion was performed by using [Fujifilm Perceptual] in an older version of XMF.
Fujifilm Perceptual: Performs colour reproduction in priority to tone scale compared with [Fujifilm Perceptual].
In [Adobe Basic] mode, you can select from 4 types, [Saturation], [Perceptual], [Relative Colorimetric], and [Absolute Colorimetric]. Also, when [Use embedded rendering intent] is selected, colour conversion is performed using the rendering intent specified in the document.
*2RGB Grey is when R, G and B are all equal amounts. Set when you do not want to include CMY in grey line art or text. (If [Convert RGB grey of text and line art to black] is not set, RGB Grey is converted to CMY. As a result, the target colour may not be reproduced accurately in output.)
*3The ColorPath Sync linked function is only provided in North America and Europe.
Jobs and job templates created in Ver. 4.0 and earlier may have different colour conversion results when processed in Ver. 4.1 and later.
Such jobs and job templates are displayed with a different colour in the Queue screen, [Add Job] dialog, and the list in [Administration] - [Templates] - [Job Templates]. This display enables you to check at a glance whether or not the items are compatible.
The display colours vary as follows depending on the warning type.
Display Colour | Warning Type |
---|---|
Blue | Colour conversion was performed in the Adobe colour conversion mode and Document Retargeting was checked |
Orange | Grey conversion was performed |
Red | Colour conversion was performed in the colour conversion mode of XMF |
Purple | Pages are assigned to multiple output devices (workflow items for which different press colour spaces are set)* |
*Even when multiple output devices (workflow items for which different press colour spaces are set) are set in a job, if the pages are not assigned, the warning is not displayed.
XMF has a tool for maintaining compatibility with previous versions. Under certain conditions, this tool can be used to create a device link profile and obtain the same output results as when a job or job template created in a previous version is used.
