Job Settings

[Overprint] Pane

Set the overprint in the [Overprint] pane.

You can set normal overprinting and Finished PDF/X overprinting.

Note

Overprint is a function that prints the colour of the upper plate over that of the lower plate in portions where colours overlap. When the colour of the lower plate is darker than that of the upper plate, the colour of the lower plate shows through.
On the other hand, knockout is a function that does not print the colour of the lower plate and prints only the colour of the upper plate in portions where colours overlap. Normally, the overprint and knockout settings are configured in the input data. However, the overprint settings configured for this function can be given priority over the overprint settings in the input data.

You can set overprint by job, section or page. In the [Job Structure] pane of Job Element Manager, select the setting unit from [Job Description], [Section], and [Page] in advance.

Restriction

Job overprint settings are applied to sluglines, custom marks and dynamic marks.

If the input file is a separated PS/PDF or a PDF of a separated PS or PDF that has been recomposited in XMF, the overprint settings set in XMF are not applied.

Normal Overprint Settings

ID Setting Description

1

Overprint Rule

Respect document settings: The overprint settings for the input data have priority.

Force overprint black text and lineart: Overprints when the size and density of black text and the density of black line art are the set numerical values.

Force knockout of all elements: Performs force knockout processing on all objects.

Force knockout except for black text: Overprints when the size and density of black text are the set numerical values. Force knockout processing is performed on objects other than black text.

Force knockout except black text and lineart: Overprints when the size and density of black text and the density of black line art are the set numerical values. Force knockout processing is performed on objects other than black text and black line art.

Expert user mode: Any of [Force Overprint of Black Lineart], [Force Overprint of Black Text], [Force Overprint] and [Force Overprint Mode] can be set.

Note
  1. In the case of [Export user mode], the [Force Overprint of Black Lineart] and [Force Overprint of Black Text] settings have priority over [Force Overprint] and [Force Overprint Mode].

2

Force Overprint of Black Lineart

This can only be selected when [Overprint Rule] - [Expert user mode] is selected.

When the checkbox is checked, force overprint is performed for black line art.

From Tint Value: The density of black line art can be entered within the range of 0 to 100.

Note
  1. If a value outside of this range is entered, the setting value is automatically changed to a value within the range.

3

Force Overprint of Black Text

This can only be selected when [Overprint Rule] - [Expert user mode] is selected.

When the checkbox is checked, force overprint is performed for black text.

Smaller Than: A value of 0 or higher can be entered as the size of black text.

From Tint Value: The density of black text can be entered within the range of 0 to 100.

Note
  1. If a value outside of this range is entered, the setting value is automatically changed to a value within the range.
Caution
  1. This cannot be set for outlined text (objects).

4

Force Overprint

This can only be selected when [Overprint Rule] - [Expert user mode] is selected.

When the checkbox is checked, force overprint or knockout can be set.

When the checkbox is cleared, the overprint settings become those of the input data.

Always Overprint: Overprint is always performed for all line art and text.

Always Knockout: Knockout processing is always performed for all line art and text.

5

Force Overprint Mode

This can only be selected when [Force Overprint] - [Always Overprint] is selected.

If the colour value is 0%, DeviceN and other colour space objects are processed as having 0% colour, whereas DeviceCMYK is processed as having no colour plate. OPM processing enables the operation for the colour value of DeviceCMYK to be controlled.

Standard OPM: Processes as if there is a colour plate and the colour of the lower plate is knocked out.

Illustrator OPM: Processes as if there is no colour plate and the colour of the lower plate is overprinted.

Note
  1. This setting can be configured when both the upper plate and lower plate are process colours.
  2. For the device colour, this setting is not applied if the upper plate includes a colour element of the lower plate.
  3. If either the upper or lower plate is a spot colour plate such as a Separation or DeviceN colour, the settings are not applied and overprinting always occurs.

6

Force Knockout of CMYK White Objects

Changes the overprint setting for the line art and text of white objects to perform force knockout processing when page preparation processing is performed. White objects are displayed in the following state:

DeviceCMYK: C=M=Y=K=0%

DeviceRGB: R=G=B=0%

DeviceGray: 0%

The force knockout process is performed after the preflight/action list process, and is applied to the input data after page preparation is completed.

Note
  1. This can only be set for line art and text. It cannot be set for shading objects and images.
  2. This setting can only be set in the job settings. It cannot be set for each section or page.

7

Treat separation 'None' the same as 'CMYK white'

Processes by converting line art and text of Separation None objects to CMYK white objects (DeviceCMYK: C=M=Y=K=0%).

Note
  • This can only be set for line art and text. It cannot be set for shading objects and images.
  • This setting can only be set in the job settings. It cannot be set for each section or page.
  • If the input file is a separated PS/PDF or a PDF of a separated PS/PDF that has been recomposited in XMF, this setting is not applied.

8

Use Creative Suite Blending

The spot colour overprint process method was changed from APPE 2.0 (XMF Ver. 2.5). This function is for ensuring compatibility with APPE 1.x.

If the checkbox is checked, the AppearanceBasedBlending mode is set. The colour value for an overlapping portion of the upper and lower plates is the same as the calculation result of APPE 2.0 (XMF Ver. 2.0), and is also the same as that obtained with the colour separation algorithm in the Adobe CS application.

This setting is enabled in the following cases;

  1. When any one of [Force overprint black text and lineart], [Force Overprint of Black Lineart], [Force Overprint of Black Text] and [Force Overprint] is selected for the [Overprint Rule] setting
  2. When a spot colour is set to be output as a process colour in the [Inks] settings of the device

When the checkbox is cleared, the NewellBlending mode is set. The colour value for an overlapping portion of the upper and lower plates is the same as the calculated result of APPE 1.1 (XMF Ver. 1.5) and earlier.

Example) Text: black 100%, green area: spot colour, blue area: process
Input Image

[Use Creative Suite Blending] is selected

The mode changes to the AppearanceBasedBlending mode. In addition to the black plate, the overlapping portions of the K plate over spot colour plates are also separated into the C, M and Y plates. This is also the same for objects other than black objects.

[Use Creative Suite Blending] is not selected

The mode changes to the NewellBlending mode.

Note

If settings configured in the job settings are changed in the section or page settings, the changed places are displayed in orange in the job settings. If at that time the settings are changed in the job settings, the setting details of the section and page settings are changed to those of the job settings. Furthermore, when the details set in the page settings are changed in the section settings, the setting details of the page settings are changed to those of the section settings. In this way, the overprint settings increase in priority in order of page settings, section settings, and job settings.

If different settings are set for each page and then imposition is set, the page settings are applied even when the pages are arranged on the same imposition.

Restriction

With regards to the white objects (black 0%) of spot colours, if [Force Overprint] - [Always Overprint] and [Force Overprint Mode] are not selected or [Illustrator OPM] is selected, and additionally if [White Overprint] is selected, the white objects will disappear.

Since [Transparency] - [Use Creative Suite Blending] setting needs to be set when APPE is started, the render process restarts automatically when this setting is selected or deselected.

Finished PDF/X Overprint Setting

To set Finished PDF/X overprint, select [Level1] or [Level2] in [Finished PDF/X] pane - [Finished PDF/X Level].

Caution

The Finished PDF/X overprint settings can only be set in the job settings. Settings cannot be configured for each section or page.

ID Setting Description

1

Overprint Rule

Keep: Maintains the overprint settings of the input PDF, and generates the Finished PDF/X.

Delete: Deletes the overprint settings of the input PDF, performs knockout processing for all text and objects, and generates the Finished PDF/X.

2

Force Overprint of Pure Black

If the checkbox is checked, when the colour space is CMYK or Grey, force overprint is set for 99% or higher black line art and text, and the Finished PDF/X is generated. In addition to DeviceCMYK, Separation colour space is also included in CMYK.

Note
  1. The settings of [Force Overprint of Pure Black] have priority over those of [Overprint Rule].
    When overprint is set for all objects:
    If [Overprint Rule] - [Delete] is selected and [Force Overprint of Pure Black] checkbox is checked, overprint is only set for line art and text that are 100% black. Knockout processing is performed for the other objects.
    When knockout processing is set for all objects:
    If [Overprint Rule] - [Keep] is selected and [Force Overprint of Pure Black] checkbox is checked, overprint is only set for line art and text that are 100% black. The settings of the input PDF are maintained for the other objects.

3

Force Knockout of CMYK White Objects

Changes the overprint setting for the line art and text of white objects to perform force knockout processing when page preparation processing is performed.

White objects are displayed in the following state:

DeviceCMYK: C=M=Y=K=0%

DeviceRGB: R=G=B=100%

DeviceGray: 100%

The force knockout process is performed after the preflight/action list process, and is applied to the input data after page preparation is completed.

Note
  1. This can only be set for line art and text. It cannot be set for shading objects and images.
  2. This setting can only be set in the job settings. It cannot be set for each section or page.
