When you save an Illustrator file in sure formats, the native transparency information is retained. For case, when you salve a file in Illustrator CS (or later) EPS format, the file contains both native Illustrator data and EPS data. When yous reopen the file in Illustrator, the native (unflattened) data is read. When you identify the file into another application, the EPS (flattened) information is read.

Most flattening

If your certificate or artwork contains transparency, to be output it normally needs to undergo a process chosen flattening. Flattening divides transparent artwork into vector-based areas and rasterized areas. As artwork becomes more complex (mixing images, vectors, blazon, spot colors, overprinting, so on), so does the flattening and its results.

Flattening may exist necessary when you lot print or when you save or export to other formats that don't support transparency. To retain transparency without flattening when y'all create PDF files, save your file every bit Adobe PDF 1.4 (Acrobat 5.0) or later on.

You can specify flattening settings then save and use them as transparency flattener presets. Transparent objects are flattened according to the settings in the selected flattener preset.

Transparency flattening cannot be undone after the file is saved.

Overlapping art that is divided when flattened — Overlapping art is divided when flattened.

For more than information on transparency output issues, see the Impress Service Provider Resources page of the Adobe Solutions Network (ASN) (English language just), available on the Adobe website.

File formats that retain transparency

When you lot salvage an Illustrator file in certain formats, the native transparency information is retained. For example, when you save a file in Illustrator CS (or later) EPS format, the file contains both native Illustrator information and EPS data. When you lot reopen the file in Illustrator, the native (unflattened) data is read. When you lot identify the file into another application, the EPS (flattened) data is read.

When possible, go on your file in a format in which native transparency information is retained, allowing you lot to brand edits equally necessary.

Native transparency data is retained when you save to the following formats:

AI9 and after
AI9 EPS and afterward
PDF 1.4 and later (when Preserve Illustrator Editing Capabilities choice is selected)

Illustrator flattens artwork when you perform any of the following actions:

Print a file that contains transparency.
Save a file that contains transparency in a legacy format such as native Illustrator eight and earlier, Illustrator 8 EPS and before, or PDF 1.3 format. (For the Illustrator and Illustrator EPS formats, you can choose to discard transparency rather than flatten it.)
Export a file that contains transparency to a vector format that does not understand transparency (such as EMF or WMF).
Re-create and paste transparent fine art from Illustrator into another application with both the AICB and the Preserve Appearance options checked (in the File Treatment & Clipboard section of the Preferences dialog box).
Export in SWF (Wink) or employ the Flatten Transparency control with the Preserve Blastoff Transparency selection selected. This control lets you preview how artwork volition expect when exported in SWF.

For more information on creating and press transparency, run into the Transparency white paper in the Adobe Technical Info/White Papers folder on the Illustrator CD. You tin can as well find more than data on printing and flattening files with transparency in the Adobe Illustrator User to User forum. This is a public forum that offers a wealth of tips and answers to oftentimes asked questions, and can be found at www.adobe.com/support/forums.

Set transparency flattening options for press

Select Advanced on the left side of the Impress dialog box.

Select a flattening preset from the Preset menu, or click Custom to set up specific flattening options.

If the artwork contains overprinted objects that collaborate with transparent objects, select an pick from the Overprints card. Y'all can preserve, simulate, or discard overprints.

If the artwork does non contain transparency, the certificate will non exist flattened and the flattening settings are not relevant. Utilise the Flattener Preview console to make up one's mind which areas of the artwork incorporate transparency.

Transparency Flattener options

You can set Transparency Flattener options when creating, editing, or previewing flattener presets in Illustrator, InDesign, or Acrobat.

Highlight (preview) options

None (Color Preview)

Disables previewing.

Rasterized Circuitous Regions

Highlights the areas that will be rasterized for performance reasons (equally determined by the Rasters/Vectors slider). Keep in listen that the purlieus of the highlight surface area has a higher probability of producing stitching issues (depending on the print-driver settings and the rasterization resolution). To minimize stitching bug, select Clip Complex Regions.

Transparent Objects

Highlights the objects that are sources of transparency, such as objects with partial opacity (including images with alpha channels), objects with blending modes, and objects with opacity masks. In addition, annotation that styles and effects may contain transparency, and overprinted objects may be treated as sources of transparency if they are involved in transparency or if the overprint needs to exist flattened.

All Affected Objects

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 past the flattening procedure—their strokes or patterns will be expanded, portions of them may go rasterized, and then on.

Afflicted Linked EPS Files (Illustrator merely)

Highlights all linked EPS files that are affected past transparency.

Afflicted 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 patterns that will be expanded if involved in transparency.

Outlined Strokes

Highlights all strokes that will exist outlined if involved in transparency or because Catechumen All Strokes To Outlines is selected.

Outlined Text (Illustrator and InDesign)

Highlights all text that will exist outlined if involved in transparency or because Convert All Text To Outlines is selected.

note: In the terminal output, outlined strokes and text may appear slightly different from native ones, especially very thin strokes and very small text. However, the Flattener Preview doesn't highlight this altered appearance.

Raster-Fill Text And Strokes (InDesign only)

Highlights text and strokes that have rasterized fills equally a result of flattening.

All Rasterized Regions (Illustrator and InDesign)

Highlights objects and intersections of objects that will be rasterized because there is no other manner of representing them in PostScript or because they are more complex than the threshold specified by the Rasters/Vectors slider. For example, the intersection of two transparent gradients will always be rasterized, fifty-fifty if the Rasters/Vectors value is 100. The All Rasterized Regions option also shows raster graphics (such as Photoshop files) involved in transparency, and raster effects such as drib shadows and feathers. Annotation that this option takes longer to procedure than the others.

Transparency Flattener Preset options

Name/Preset

Specifies the name of the preset. Depending on the dialog box, you can type a proper noun in the Name text box or have the default. Y'all can enter the name of an existing preset to edit that preset. Still, you can't edit the default presets.

Raster/Vector balance

Specifies the corporeality of vector information that will exist preserved. Higher settings preserve more than 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.

Note: The corporeality of rasterization that occurs depends on the complication of the folio and the types of overlapping objects.

Line Art And Text Resolution

Rasterizes all objects, including images, vector artwork, text, and gradients, to the specified resolution. Acrobat and InDesign allow a maximum of 9600 pixels per inch (ppi) for line fine art, and 1200 ppi for gradient mesh. Illustrator allows a maximum of 9600 ppi for both line art and slope mesh. The resolution affects the precision of intersections when flattened. Line Fine art and Text Resolution should generally be ready to 600‑1200 to provide high-quality rasterization, especially on serif or pocket-size indicate sized type.

Slope And Mesh Resolution

Specifies the resolution for gradients and Illustrator mesh objects rasterized equally a result of flattening, from 72 to 2400 ppi. The resolution affects the precision of intersections when flattened. Gradient and mesh resolution should generally exist set between 150 and 300 ppi, because the quality of the gradients, drib shadows, and feathers practise not improve with higher resolutions, simply printing time and file size increase.

Convert All Text To Outlines

Converts all blazon objects (signal type, area type, and path blazon) to outlines and discards all type glyph information on pages containing transparency. This option ensures that the width of text stays consistent during flattening. Note that enabling this pick will cause small fonts to announced slightly thicker when viewed in Acrobat or printed on low-resolution desktop printers. It doesn't affect the quality of the blazon printed on high-resolution printers or imagesetters.

Catechumen All Strokes To Outlines

Converts all strokes to simple filled paths on pages containing transparency. This option ensures that the width of strokes stays consequent during flattening. Note that enabling this option causes thin strokes to appear slightly thicker and may degrade flattening performance.

Clip Complex Regions

Ensures that the boundaries between vector artwork and rasterized artwork autumn along object paths. This pick reduces stitching artifacts that event when part of an object is rasterized while another part of the object remains in vector form. However, selecting this selection may result in paths that are as well complex for the printer to handle.

note: Some print drivers procedure raster and vector art differently, sometimes resulting in color stitching. You may exist 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.

Stitching, where rasters and vectors meet.

(Illustrator only) Select Preserve Alpha Transparency (Flatten Transparency dialog box simply)

Preserves the overall opacity of flattened objects. With this option, blending modes and overprints are lost, only their advent is retained within the candy artwork, along with the level of alpha transparency (as when you rasterize artwork using a transparent background). Preserve Alpha Transparency tin can be useful if you are exporting to SWF or SVG, since both of these formats support alpha transparency.

(Illustrator simply) Select Preserve Spot Colors And Overprints (Flatten Transparency dialog box but)

Mostly preserves spot colors. It also preserves overprinting for objects that aren't involved in transparency. Select this option when printing separations if the certificate contains spot colors and overprinted objects. Deselect this choice when saving files for use in page-layout applications. With this selection 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 awarding.

Preserve Overprint (Acrobat only)

Blends the color of transparent artwork with the background color to create an overprint result.

Preview which areas of artwork volition be flattened

Apply the preview options in the Flattener Preview to highlight areas that are affected by flattening. You can use this color-coded information to suit flattening options.

The Flattener Preview is not intended for precise previewing of spot colors, overprints, and blending modes. Instead, utilise Overprint Preview way for those purposes.

Display the Flattener Preview console (or dialog box):

In Illustrator, choose Window > Flattener Preview.
In Acrobat, choose Tools > Print Production > Flattener Preview.
In InDesign, choose Window > Output > Flattener Preview.

From the Highlight menu, cull the kind of areas y'all want to highlight. The availability of options depends on the content of the artwork.

Select the flattening settings you lot want to use: Either choose a preset or, if available, gear up specific options.

(Illustrator) If the flattening settings aren't visible, select Bear witness Options from the panel menu to display them.

If the artwork contains overprinted objects that interact with transparent objects, in Illustrator, select an option from the Overprints menu. You can preserve, simulate, or discard overprints. In Acrobat, choose Preserve Overprint to blend the color of transparent artwork with the groundwork color to create an overprint effect.

At any time, click Refresh to display a fresh preview version based on your settings. Depending on the complexity of the artwork, you may need to wait a few seconds for the preview image to appear. In InDesign, you tin can also choose Auto Refresh Highlight.

In Illustrator and Acrobat, to magnify the preview, click in the preview area. To zoom out, Alt-click/Option-click in the preview area. To pan the preview, hold down the spacebar and drag in the preview area.

Flattener Preview panel overview

You apply the preview options in the Flattener Preview panel to highlight the areas affected by flattening artwork. Y'all can use this data to conform the flattening options, and even use the panel to save flattener presets. To brandish the Flattener Preview panel, choose Window > Flattener Preview.

A. Panel menuB. Refresh buttonC. Highlight carteD. Overprint menuE. Transparency flattening settingsF. Preview area

Y'all can control the speed and quality of the preview paradigm by selecting an option from the console card. Select Quick Preview to compute the quickest preview; select Detailed Preview to add the selection All Rasterized Regions to the Highlight pop‑up menu (this option is more than performance-intensive to compute).

Keep in mind that the Flattener Preview panel is not intended for precise previewing of spot colors, overprints, blending modes, and image resolution. Use Overprint Preview mode in Illustrator to preview spot colors, overprints, and blending modes as they will appear when output.

About transparency flattener presets

If y'all regularly print or export documents that contain transparency, you tin can automate the flattening process past saving flattening settings in a transparency flattener preset. You can then apply these settings for print output too as for saving and exporting files to PDF 1.3 (Acrobat four.0) and EPS and PostScript formats. In add-on, in Illustrator you can apply them when saving files to earlier versions of Illustrator or when copying to the clipboard; in Acrobat, you can besides apply them when optimizing PDFs.

These settings besides control how flattening occurs when you consign to formats that don't support transparency.

You can cull 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 Salve Equally dialog box. Yous can create your own flattener presets or choose from the default options provided with the software. The settings of each of these defaults are designed to lucifer the quality and speed of the flattening with an appropriate resolution for rasterized transparent areas, depending on the document'due south intended use:

High Resolution

is for final press output and for high-quality proofs, such as separations-based color proofs.

Medium Resolution

is for desktop proofs and impress-on-demand documents that will be printed on PostScript color printers.

Low Resolution

is for quick proofs that volition be printed on black-and-white desktop printers and for documents that will be published on the web or exported to SVG.

Create or edit a transparency flattener preset

You can save transparency flattener presets in a separate file, making it easy to back them up or to make them bachelor to your service providers, clients, or others in your workgroup. In InDesign, transparency flattener preset files take an .flst extension.

Choose Edit > Transparency Flattener Presets.

To create a new preset, click New.
To base a preset on a predefined preset, select i in the listing and click New.
To edit an existing preset, select the preset and click Edit.

You can't edit the default flattener presets.

Click OK to return to the Transparency Flattener Presets dialog box, and click OK over again.

Export and import a custom transparency flattener preset

You can export and import transparency flattener presets in order to share them with your service providers, your clients, or others in your workgroup.

Cull Edit > Transparency Flattener Presets.

Select a preset in the listing.

To export a preset to a separate file, click Save (InDesign) or Export (Illustrator), specify a proper name and location, and so click Salve.

Consider saving the preset exterior of the application'due south preferences folder. That style, it won't be lost if yous delete your preferences.
To import presets from a file, click Load (InDesign) or Import (Illustrator). Locate and select the file containing the preset you lot want to load, and then click Open.

Rename or delete a custom transparency flattener preset

Choose Edit > Transparency Flattener Presets.

Select a preset in the list.

To rename an existing preset, click Edit, type a new proper noun, and then click OK.
To delete a preset, click Delete, and then click OK to confirm the deletion.

note: You cannot delete the default presets.

Flatten transparency for private objects

The Flatten Transparency command lets you see what your artwork volition wait similar when flattened. For instance, you might use this command before saving the file in SWF (Flash) format or if you are having problems printing legacy art where transparency may be the culprit.

Cull Object > Flatten Transparency.

Select the flattening settings you want to employ, either by choosing a preset or setting specific options.

To save the flattening settings for use with other objects and documents in the current session, click Save Preset. If you want to create a permanent preset, choose Edit > Transparency Flattener Presets instead.

Rasterize all artwork during printing

When y'all print to a low-resolution or non-PostScript printer, such equally a desktop inkjet printer, you lot tin can choose to rasterize all artwork during press. This selection is useful when printing documents that incorporate circuitous objects (such as objects with smooth shading or gradients) considering information technology reduces the possibility of errors.

Select Advanced on the left side of the Print dialog box.

This choice is only available if the printer driver for the selected printer supports bitmap printing.
