CMYK Target Profile

Select this when you use the CMYK target profile as default.

Allows you to set the CMYK target profile to be used.

This setting is used when printing according to the printing standard (ISO Coated, etc.) or other printing machines.

Selecting this item enables you to set Paper Simulation, which is displayed below this item.

The setting of this item is not applied, if you select Use Embedded CMYK Profile on the Optional Settings tab.

Paper Simulation

Check when you execute the Paper Simulation as default.

If you choose not to use Paper Simulation (Rendering: Relative), remove the check from the check box.

If you choose to use Paper Simulation (Rendering: Absolute), check this check box.

To select this item, select CMYK Target Profile above this item ahead.

Printer Profile Tab

Printer Profile

Specifies the default printer profile.

Paper Type Link

Allows you to set whether or not to enable the paper type link function as default settings. An appropriate profile is automatically selected according to the paper. Paper Type Link is combination data of a paper type and a printer profile. To specify a combination, use Profile Management. This is also available for a profile that is created by using a utility other than Color Centro.

Optional Settings tab

Tone Curve

Selects the default tone curve setting.

Set the values for Image and Text/Graphic.

Keep 100% Density for Text/Graphics

Select default of K100% output.

• Whether to output objects at the maximum density.

Target: Only objects whose input values are K100% (text, graphics)
K100%: RGB = (0,0,0) or CMYK = (0,0,0,100)

• This function prints black (not gray) in K only (100%).

• This function prints objects in pure black (K) not in rich black (CMYK).

• Even if you apply a tone curve whose maximum output value is less than 100%, this function keeps K100%.

• This function is not available on color machines.

Pure Black

Selects the default Pure Black settings.

• Whether to use Pure Black

• Target when used

Pure Black: A function that prints black (not gray) in K (100%).

Black is printed in pure black (K) instead of rich black (CMYK).

It applies to positions where RGB = (0,0,0) or CMYK = (0,0,0,100) is specified.

• Prevents excessive application of toner (overlaying four colors).

• Prevents toner from being used excessively.

• Reproduces K more stably than four-color K.

Black Overprint

Selects the default black overprint settings.

• Whether to use black overprint

Black overprint: A function that prints the underlying color over an object in K = 100%.

• As the underlying color is used, the K that is printed is not pure black.

• Prevents white space generated around an object.

If you choose not to use this function, the underlying color is removed before printing. (Knock-out processing)

Gray Replacement

Selects the default gray replacement settings.

• Whether to use gray replacement

• Target when used

Select the values for RGB and CMYK respectively.

Gray Replacement: A function that prints gray in K (1% to 99%).

It applies to positions where the R, G, and B values are equal or CMYK = (0,0,0,X) is specified

(where X is a value between 1 to 99).

• Stabilizes the quality of gray

(because it can be applied to all ranges including highlights and shadows, with the exception of solids).

Composite Overprint

Selects the default composite overprint settings.

• Whether to use composite overprint

• Priority target when used

Composite Overprint: A function of overprinting

• Prints by overlaying colors, not limited to K = 100%.

• Reproduces transparency (an overlay of colors) represented on an application that created the image.

If you choose not to use this function, the underlying color on objects is removed before printing. (Knock-out processing)

Use Spot Color

Selects the default spot color setting.

• Whether to use a spot color

AlternativeColor Table

Select an alternative color table to use.

Use Embedded RGB Profile

Selects the default setting of profile used in color conversion.

• Whether to use a profile that is embedded in an object in print data as the profile of RGB source

Required profile

When selected: Embedded profile

When not selected: Profile provided on the image controller

Select this option when you print by using a profile that you assign in an application.

Example: Adobe Photoshop

When no profile is embedded, the default profile is used.
To specify the default profile, use Color Configuration Management.

Use Embedded CMYK Profile

Selects the default setting of profile used in color conversion.

• Whether to use a profile that is embedded in an object in print data as the CMYK target profile

Required profile

When selected: Embedded profile

When not selected: Profile provided on the image controller

Select this option when you print by using a profile that you assign in an application.

Example: Adobe Photoshop

When no profile is embedded, the default profile is used.
To specify the default profile, use Color Configuration Management.

RGB Simulation

Selects the default RGB Simulation setting.

• Whether to perform RGB simulation

RGB Simulation: A function that simulates the conversion from RGB data to CMYK data in the CMYK color space when the data is converted.

With RGB data, this machine can achieve colors close to the printing standard.

To select this item, select RGB Source Profile in the RGB tab.

PDF/X output intent

Selects the default output intent setting of a PDF file.

• Whether to use a profile that is embedded in a PDF file as the CMYK target profile

PDF/X: ISO standard, which is used as print data.

Output intent: Profile specified in the color settings

Color conversion target

When selected: Embedded output intent

(If no output intent is embedded in the PDF file, the target is selected based on the CMYK color conversion settings. )

When not selected: CMYK profile

(The profile you select in Color Configuration Management or Default Manual Settings)

For a PDF file without PDF/X used, select Use Embedded RGB Profile or Use Embedded CMYK Profile.

Use CIE Color

Select default of the color space to be used in color conversion.

• Whether to use the color space that the CIE color system configures

If you select this item, colors tend to become lighter.

Because of gradation changes, you may be able to reduce blocked up shadows.

To enhance the visibility, change the tone curve to the one that can output colors thicker.

CIE: CIE = Commission Internationale de l'Eclairage (International Commission on Illumination)
