Use these options to specify how to convert the fonts and images in
your documents into PDF. The file size of your output PDF is
largely determined by the options you choose in this dialog box.

FONT
OPTIONS
True Type Font Embedding
- By default, easyPDF Printer is set to "Embed
(Subset)". This option means that easyPDF Printer will
embed the TrueType Fonts used in your document into the PDF output,
but only for the characters used in the document. As a result, you
will get a reasonably-sized PDF which can be displayed correctly in
any computer. For example, you can download this Japanese PDF and view it in a computer
that doesn't have Japanese font installed. Your computer can
display the PDF correctly because the required Japanese fonts are
already embedded in the PDF itself.
- By selecting "Embed (Fullset)," you are
telling easyPDF Printer to embed the entire set of the TrueType
fonts used in your document into the PDF output. Selecting this
option will cause the size of the PDF to increase
significantly.
- By selecting "Don't embed," you are telling
easyPDF Printer to place only the descriptions of the TrueType
Fonts used in your document into the PDF output. The actual
TrueType Fonts will not be embedded in the PDF. This will produce a
very compact PDF but will display well only on machines that have
these fonts installed.
Embed as Type 0 Font
- Use this option only if you have non-standard fonts, like
Barcode font.
Note: Non-Roman fonts are always embedded as Type 0 font regardless
of this option.
Font substitution
- If you select "Don't substitute fonts", then no substitution
will be made for TrueType fonts used in the document.
- If you select "Use font substitution table", then substitutions
will be made according to the table under the "Device Settings"
section of the easyPDF Printer properties (can be found in the
Control Panel).
- If you select "Use PDF's built in fonts", then Type 1 fonts
will be substituted for all TrueType fonts.
IMAGE
OPTIONS
Downsize image
Selecting this option will reduce resolution of any images to
the dpi value displayed and can greatly reduce the size of the
resulting PDF file. If the actual image resolution in your original
document is less than the downsize value, easyPDF Printer will not
downsize the original image resolution.
Please follow the following guidelines in setting the downsize
value:
- For Online Viewing: Set the downsize value to
96 dpi (any image with resolution higher than 96 dpi will be
converted to 96 dpi image). This will produce a small PDF file
size, suitable for online viewing. At 96 dpi, images in your
document will still look acceptable on a computer screen, but will
appear somewhat blurry when printed out on paper.
- For Online Viewing and Printing: Set the
downsize value to 300 dpi (any image with resolution higher than
300 dpi will be converted into 300 dpi image). In most cases, this
will preserve the high resolution images in your original document.
The PDF file size will be slightly larger, but the document will
look great both on the screen and when printed out on paper.
- For High-Resolution Printing: Uncheck the
"Downsize image" feature and easyPDF Printer will preserve the
original resolution of the images in your document (up to 4000
dpi).
Compression Method
easyPDF Printer offers two compression methods:
- ZIP: Lossless compression format, perfect for high
resolution printing.
ZIP (also called Flate) is a compression method that works well on
images with large areas of single colors or repeating patterns, but
also works with other images. The ZIP method is lossless, which
means it does not remove data to reduce file size and so does not
affect an image’s quality.
- JPEG: Lossy compression format, perfect for online
viewing.
The JPEG compression method is suitable for grayscale or color
photographic images. JPEG is lossy compression, which means it
eliminates data to achieve much smaller file sizes than the ZIP
compression. JPEG quality may be set from 5% to 100%.
- JPEG 2000: Lossy compression format, perfect for online
viewing.
JPEG 2000 has a superior compression performance in that it has
slight fidelity advantage over JPEG. JPEG 2000 has clear advantage
over JPEG with respect to features such as scalability and editing
capability. For images at lower bit rates JPEG 2000 performs
significantly better than JPEG in terms of visibility and blocking.
JPEG 2000 quality may be set from 5% to 100%.
Note: The default setting is JPEG compression at 85%
quality.
