Data Objects - Ricoh InfoPrint Pro C900AFP Manual

addition, AFP Resource Installer automatically installs all the generic halftone and
tone transfer curve CMRs in any resource library you create.
You can download device-specific CMRs for InfoPrint printers such as the
InfoPrint 5000 from the InfoPrint Solutions Company Web site:
http://www.infoprint.com
If you need more CMRs, you can create them by using wizards provided in AFP
Resource Installer. See the online help for details about the wizard.
If you use AFP Resource Installer to create a CMR, the software automatically
installs the CMR in a resource library. You can also use AFP Resource Installer to
install CMRs that you get from your printer manufacturer.

Data objects

Presentation data objects contain a single type of data (such as GIF, JPEG, PNG,
and TIFF images) and can be used in your print jobs. These data objects can be
placed directly in a page or overlay or can be defined as resources and included in
pages or overlays. Using a data object as a resource is more efficient when that
object appears more than once in a print job; resources are downloaded to the
printer just once and referenced as needed.
Data objects can either be included inline with a print job or installed in a resource
library by using software such as AFP Resource Installer. If you install your data
objects in a resource library, you can associate color conversion CMRs with them.
Types of data objects
Image data objects can be stored in a number of different formats, including AFPC
JPEG Subset, EPS, GIF, IOCA, PDF, PNG, and TIFF. These image types are
device-independent so they can be used by different systems and still be
interpreted consistently.

AFPC (AFP Consortium) JPEG Subset files, formerly called JPEG File
Interchange Format (JFIF) files, are bitmap image files that are compressed by
using Joint Photographic Experts Group (JPEG) compression. As a result, AFPC
JPEG Subset files are most commonly referred to as JPEG files. JPEG files most
commonly use the file extension .jpg, but can also use .jpeg, .jpe, .jfif, and .jif.
JPEG compression deletes information that it considers unnecessary from images
when it converts them. JPEG files vary from having small amounts of
compression to having large amounts of compression. The more an image is
compressed, the more information is lost. If the image is compressed only once,
there usually is no noticeable effect on the image. However, if the image is
compressed and decompressed repeatedly, the effects of deleting information
become more noticeable.
JPEG compression is commonly used for photographs, especially photographs
that are transmitted or displayed on Web pages. The compression makes the
files small enough to transmit on a network efficiently, but leaves enough
information that the image is still visually appealing.
EPS is a PostScript graphics file format that follows conventions that Adobe
Systems defined. EPS files support embedded ICC profiles.
