A media configuration can be configured to emulate the substrate effects that may be seen on offset or flexographic presses.
● For offset press sheets, proofs can reproduce the press mottle and paper grain seen on some press sheets of certain paper types, such as Paper Type 3.
● For flexographic presses, proofs can emulate printing on corrugated cardboard.
1. In Proofer Viewer, from the Configure menu, select Media Configuration.
2. Select a media configuration, and click Edit.
3. In the Emulation list, select a paper type.
4. Click Settings to view or edit the emulation settings.
5. Click OK.
6. Click Save or Save As and save the modified media configuration under a new name.
Note: Changing a media configuration’s Emulation settings for a substrate effect will change how the media configuration reproduces color. For the best color control, create a custom ICC profile for the custom media configuration. Also process a test file to evaluate the results.
Substrate Effects dialog box
Press Mottle
Press mottle is the spotty or uneven appearance of press ink on paper. Typically, it is most visible in solid areas.
Mottle
Specifies the degree of press mottle to emulate on a proof. Choose one of the following options:
- None: turns off the emulation of press mottle
- Fine: emulates fine mottle texture
- Medium: emulates medium mottle texture
- Coarse: emulates coarse mottle texture
Intensity (0 - 100 %)
Specifies how much mottle texture to emulate. An intensity of 1% appears lighter than an intensity of 100%. Decimals are not allowed.
Paper Grain
Specifies whether to emulate the grain seen on press sheets for the selected paper type. Choose one of the following options:
- None: turns off the emulation of paper grain
- Paper Grain: emulates the grain seen on press
Corrugation
The Corrugation area defines the characteristics of the corrugation bands. The flutes in cardboard often appear as bands in the printed piece.
Banding Orientation
Turns on and off emulation of a corrugated substrate, such as cardboard. Choose one of the following options:
- None: turns off emulation of corrugation
- Vertical: turns on emulation of corrugation and places the bands vertically on the proof
- Horizontal: turns on emulation of corrugation and places the bands horizontally in the proof
Note: The corrugation banding is oriented with the proof, not the sheet.
Banding Type
Specifies whether to emulate dark thin bands or light thin bands. Select Dark for dark thin bands, and select Light for light thin bands.
Intensity
Specifies the intensity of the bands. Bands with higher intensity are more visible on the proof. Bands with lower intensity are less visible on the proof.
Pitch
Specifies the pitch of the bands. The pitch appears as more or less space between the bands.
Width
Specifies the width of the bands.
Preview
Displays a preview of the selected options in the Corrugation area.
