In the PitStop Server Hot Folder Editor, select the Flattening category. Enable Resolve overprint if you want to flatten overprint objects as well, without. Flattened, with Flatten Overprints off. In this case, only the Multiply blend has been flattened. The magenta outside the cyan is now solid magenta without blend. To understand flattening, the Figure below demonstrates the difference between the Choose a preset from the Overprint and Transparency Flattener options.

If your document or artwork contains transparency, to be output it usually needs to undergo a process called flattening. Flattening divides transparent artwork into vector-based areas and rasterized areas. As artwork becomes more complex mixing images, vectors, type, spot colors, overprinting, and so on dlatten, so does the flattening and its results.
You can specify flattening settings and then save and apply them as transparency flattener presets. Transparent objects are flattened according to the settings in the selected vlatten preset. Transparency flattening cannot be undone after the file is saved. Flayten the preview options in the Flattener Preview dialog box to highlight the areas and objects that are transparent, as well as those affected oferprint transparency flattening. Transparent content is highlighted in red, and the rest of the artwork appears in grayscale.
Use this information to adjust the flattener options before you apply the settings, and then save them as flattener presets. You can then apply these presets from other dialog boxes. Use the preview options in the Flattener Preview to highlight areas that are affected by flattening.
You can use this color-coded information to adjust flattening overprnit. The Flattener Preview is not intended for precise previewing of spot colors, overprints, and blending modes.
Instead, use Overprint Preview mode for those purposes. In Illustrator and Acrobat, to magnify the preview, click in the preview area.
To pan the preview, hold down the spacebar and drag in the preview area. You can set Transparency Flattener options when creating, editing, or previewing flattener presets in Illustrator, InDesign, or Acrobat. Keep in mind that the boundary of the highlight area has a higher probability of producing flatteen problems depending on the print-driver settings and the rasterization resolution.
To minimize stitching problems, select Clip Complex Regions. Highlights the objects that are sources of transparency, such as objects with partial opacity including images with alpha channelsobjects oveprint blending modes, and objects with opacity masks. In addition, note that styles and effects may contain overpeint, and overprinted objects may be treated as sources of transparency if they are involved flatfen transparency or if the overprint needs to be flattened.
Highlights all objects that are involved in transparency, including transparent objects and objects that are overlapped by transparent objects. The highlighted objects will be affected by the flattening process—their strokes or patterns will be expanded, portions of them may get rasterized, and so on. Affected Graphics InDesign only. Highlights all placed content affected by transparency or transparency effects.
This option is useful for service providers who need to see graphics that require attention to print properly.
Expanded Patterns Illustrator and Acrobat. Highlights all strokes that will be outlined if involved in transparency or because Convert All Strokes To Outlines is selected. Outlined Text Illustrator and InDesign. Highlights all text that will be outlined if involved in transparency or overpfint Convert All Text To Outlines is selected. In the final output, outlined strokes and text may appear slightly different from native ones, especially very thin strokes and very small text.
How do I work with overprint
Highlights text and strokes that have rasterized fills as a result of flattening. The Flatyen Rasterized Regions option also shows raster graphics such as Photoshop files involved in transparency, and raster effects such as drop shadows and feathers. Note that this option takes longer to process than the others.
Specifies the name of the preset. Depending on the dialog box, you can type a name in the Name text box or accept the default. You can enter the name of an existing preset to edit that preset. Overpriint the amount of vector information that will be preserved. Higher settings preserve more vector objects, while lower settings rasterize more vector objects; intermediate settings preserve simple areas in vector form and rasterize complex ones.
Select the lowest setting to rasterize all the artwork. The amount of rasterization that occurs depends on the complexity of the page and the types of overlapping objects.
Rasterizes all objects, including images, vector artwork, text, and gradients, to the specified resolution. Illustrator allows a maximum of ppi for both line art and gradient mesh. The resolution affects the precision of intersections when flattened.
Gradient and mesh resolution should generally be set between and ppi, because the quality of the gradients, drop shadows, and feathers do not improve flatfen higher resolutions, but printing time and file size increase.
Converts all type objects point type, area type, and path type to outlines and discards all type glyph information on pages containing transparency. This option ensures that the width of text stays consistent during flattening.
Setting up Flattening
Convert All Strokes To Outlines. Converts all strokes to simple filled paths on pages containing transparency. This option ensures that the width of strokes stays consistent during flattening.
Note that enabling this option causes thin strokes to appear slightly thicker and may degrade flattening performance. Ensures that the boundaries between vector artwork and rasterized artwork fall along object paths.
This option reduces stitching artifacts that result when part of an object is rasterized while another part of the object remains in vector form. However, selecting this option may result in paths that are too complex for the printer to handle.
Some print drivers process raster and vector art differently, sometimes resulting in color stitching. You may be able to minimize stitching problems by disabling some print-driver specific color-management settings.
These settings vary with each printer, so see the documentation that came with your printer for details. Preserves the overall opacity of flattened objects. With this option, blending modes and overprints are lost, but their appearance is retained within the processed artwork, along with the level of alpha transparency as when you rasterize artwork using a transparent background. Generally preserves spot colors.
Select this option when printing separations if the document contains spot colors and overprinted objects. Deselect this option when saving files for use in page-layout applications. With this option selected, overprinted areas that interact with transparency are flattened, while overprinting in other areas is preserved. The results are unpredictable when the file is output from a page-layout application.
Preserve Overprint Acrobat only. Blends the color of transparent artwork with the background color to create an overprint effect. If you regularly print or export documents that contain transparency, you can automate the flattening process by saving flattening settings in a transparency flattener preset. In addition, in Illustrator you can apply them when saving files to earlier versions of Illustrator or when copying to the clipboard; in Acrobat, you can also apply them when optimizing PDFs.
You can choose a flattener preset in the Advanced panel of the Print dialog box or of the format-specific dialog box that appears after the initial Export or Save As dialog box. You can create your own flattener presets or choose from the default options provided with the software.
You can save transparency flattener presets in a separate file. Using a separate file makes it easy to back them up or to make them available to service providers, clients, or others in your workgroup. Once you create a custom flattener preset, you can edit it in PDF Optimizer. Flattener presets created in Acrobat have a different file format from the presets created in other Adobe applications, so you cannot share them between applications.
To delete a custom preset, choose it from the Preset menu and press Delete. In the Flattener Preview dialog box, choose a preset from the menu, specify a page range, and click Apply. In the Advanced Print Setup dialog box, select the Output panel on the left, and then select a preset from the Transparency Flattener Preset menu. In the Output panel, select a preset from the Transparency Flattener Preset menu. Transparency flattening Acrobat Pro Search.
