Transparency Flattener Preset options
Name/Preset 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. However, you can’t edit the
default presets.
Raster/Vector balance Specifies 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.
Note: The amount of rasterization that occurs depends on the complexity of the page 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 art, and 1200 ppi
for gradient mesh. Illustrator allows a maximum of 9600 ppi for both line art and gradient mesh. The resolution affects
the precision of intersections when flattened. Line Art and Text Resolution should generally be set to 600-1200 to
provide high-quality rasterization, especially on serif or small point sized type.
Gradient And Mesh Resolution Specifies the resolution for gradients and Illustrator mesh objects rasterized as a result
of flattening, from 72 to 2400 ppi. The resolution affects the precision of intersections when flattened. Gradient and
mesh resolution should generally be set between 150 and 300 ppi, because the quality of the gradients, drop shadows,
and feathers do not improve with higher resolutions, but printing time and file size increase.
Convert All Text To Outlines 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. Note that enabling this option will cause small fonts to appear slightly thicker when viewed in
Acrobat or printed on low-resolution desktop printers. It doesn’t affect the quality of the type printed on high-
resolution printers or imagesetters.
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.
Clip Complex Regions 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.
Stitching, where rasters and vectors meet.
Note: 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.
(Illustrator only) Select Preserve Alpha Transparency (Flatten Transparency dialog box only) 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
