pages later in the workflow, the font downloading can be incorrect, resulting in missing fonts. This option does not
work with some printers.
Send For Each Page Downloads all fonts and resources for a given page before the page prints, and then discards the
fonts when the page has finished printing. This option uses the least printer memory.
Print Method (Acrobat Pro DC) Specifies the level of PostScript to generate for the pages. Choose the level of PostScript
appropriate for your printer.
Language (Acrobat Pro DC) Specifies the level of PostScript to generate for the pages. Choose the level of PostScript
appropriate for your printer.
Download Asian Fonts Prints documents with Asian fonts that aren’t installed on the printer or embedded in the PDF.
The Asian fonts must be present on the system.
Emit Undercolor Removal/Black Generation (Acrobat Pro DC) Black Generation calculates the amount of black to be
used when reproducing a particular color. Undercolor removal (UCR) reduces cyan, magenta, and yellow components
to compensate for the black added by the black generation. Because it uses less ink, UCR is used for newsprint and
uncoated stock.
Emit Halftones (Acrobat Pro DC) Allows you to emit the embedded halftones instead of using the halftones in the
output device. Halftone information controls how much ink is deposited at a specific location on the paper. Varying the
dot size and density creates the illusion of variations of gray or continuous color. For a CMYK image, four halftone
screens are used: one for each ink used in the printing process.
Emit Transfer Functions (Acrobat Pro DC) Emits embedded transfer functions. Transfer functions are traditionally used
to compensate for dot gain or dot loss that occurs when an image is transferred to film. Dot gain occurs when the ink
dots that make up a printed image are larger (for example, due to spreading on paper) than in the halftone screen. Dot
loss occurs when the dots print smaller. With this option, the transfer functions are applied to the file when the file is
output.
Emit Flatness (Acrobat Pro DC) allows you to use the flatness value of the PDF if the PDF already has flatness settings.
If the PDF doesn’t have any flatness settings, Acrobat controls it for the PostScript printing. The flatness value sets the
limit for how much Acrobat can approximate a curve.
Emit PS Form Objects (Acrobat Pro DC) Emits PostScript form objects for Form XObjects within the PDF. Selecting this
option reduces the overall size of the print job, but it could increase the printer memory that is used. A form XObject
is a container of graphics objects (including path objects, text objects, and sampled images) within the PDF. Form
XObjects create a single description for complex objects that can appear many times in a single document, such as
background images or company logos.
Discolored Background Correction Prevents printing problems like red boxes over graphics, or pages printing
mirrored or upside down. These problems can occur when Acrobat or Reader cannot use the default Color Rendering
Dictionaries (CRDs) on some PostScript printers.
Always Use Host Collation (Acrobat Pro DC) Specifies if you want Acrobat to always use host collation for printing
without checking the printer driver. Acrobat uses printer collation by default. Printer collation sends the print jobs
separately to the printer and allows the printer to figure out how to collate the pages. For example if you send out two
copies of a two page job, the printer receives two jobs of two pages. Host collation figures out how to collate the pages
in Acrobat and then sends that job to the printer. For example if you send out two copies of a two page job, the printer
receives a single rearranged job of four pages.
Print As Image Prints pages as bitmap images. Select this option if normal printing doesn’t produce the desired results,
and specify a resolution. This option is available only for PostScript printers.
