Introduction 11
Easy to use
Continuous-feeding ink system The printers use 500 ml reservoirs for each
colour to ensure that there is anadequate ink supply for large print jobs. Simply
check the transparent plastic reservoirs and refill them if necessary prior to
printing. In addition, the printer’s dual ink system speeds up the process of
switching between different types of ink.
Acceptance of raster-oriented data in HP RTL format In this mode, printing
begins immediately after the printer receives the first complete line of HP RTL
data. Depending on the software used, it is possible to reproduce millions of
colours, yielding high-quality results for full-colour images or 3-dimensional
renderings.
Choice of appropriate inks and media
Océ inks and media are developed specifically to work together to achieve the
widest range of colours available, for high colour fidelity. For details about the
appropriate types of media for different print jobs, see ‘Media for Océ CS
5050/5070 printers’ on page 120.

Obtaining quality reproductions
Depending on the print mode you use, inkjet printing can produce a wide
variety of print qualities. Hence, before starting a print job, it is essential that
you understand what the required output quality will be, based on the future
use of the reproduced graphic, as well as the time and cost involved in
achieving that required print quality.
Several factors can affect the quality of reproduced graphics. Use the following
guidelines to obtain optimal print quality with the Océ CS 5050/5070.
Choice of print mode
There are printing modes, each of which compromises between image quality
and speed. When printing heavy renderings, maps,or art graphics, choose one
of the quality printing modes. Certain types of media also require quality
printing modes.
To select the appropriate printing mode for a specific print job, refer to
‘Selecting quality modes’ on page 48.
Original image type
The type of original image influences the quality of the final print.
■For best results, use an original transparency (not a duplicate) with extremely
crisp edge definition.
■Print film photos are not quite as good, because they are removed one level
from the original film. Also, because of the emulsion process used to make
photo prints, edge definitions tend to be lost.
■Colour prints must be of very good quality to produce acceptable scaled
prints.
■Some digital photo files may be unacceptable for large format printing, as
they only contain a small fraction of the information contained in a film
transparency.

Introduction 13
■CD images in TIFF or EPS format of 28MB or more are preferable for high
quality prints. Avoid compressed image files such as GIF or JPEG, since these
files can lose valuable data after compression. However, if you must use a
compressed file, take into account the following:
■Choose the JPEG format in case some quality loss is acceptable. (The
compression factor determines the final image quality.)
■Choose LZW if quality loss is not acceptable.
Note: When using LZW, the compression factor will be very low on photo
images.
Original image clarity and colour
The quality of the original transparency, photograph, or digital file determines
the input as well as output clarity and colour of the image. By using a good,
clear original, you can maintain the image quality throughout the printing
process.
■An out-of-focus photograph will result in a fuzzy inkjet print, despite the
after-effects of sharpening corrections.
■Variations in film, speed, grain, or developing process can affect the lightness
or darkness of the image for which colour corrections cannot compensate.
Scanner type
It is essential to understand the required (output) print quality of an image, and
to use the appropriate scanner to scan that image into a digital file. Use a
scanner that can achieve enough colour fidelity and edge clarity to meet the
overall print requirement. An image scanned using a low-performance scanner
will lose detail, clarity, and colour.

14 Océ CS 5050/5070 User Manual
Scan resolution
Choosing the right resolution for the output print size (as well as the amount
of scaling needed after scanning) determines the best scan resolution for each
image. A resolution that is too low will diminish the print quality (insufficient
detail). A resolution that is too high slows down the raster image processor
(OGSL) without adding quality to the image.
Use the following guidelines to set end resolution:
■150 dpi for sharp, detailed images intended for close viewing
■100 dpi for viewing from a significant distance
■Keep text and logos as vector information (i. e. Postscript fonts and formats),
which will always print at the printer’s resolution.
Most scanners can interpolate or “imitate” high-resolution scanning. However,
do not use the interpolated resolution of your scanner to compute the image
size. Instead, use the scanner’s highest true optical resolution to maintain
image quality.
Post-scanning image correction and sharpening
Before printing a scanned image, you must perform some basic image
corrections and sharpening to ensure a high-quality, wide-format colour print.
Tonal correction If necessary, remove the colour cast from the midtones of an
image using a function such as “Auto" levels in PhotoShop. This function
allows you to re-adjust the black and white points in the image and redistribute
the intermediate colours proportionately. In most cases, this correction is
sufficient for properly exposed images. However, in very dark night scenes or
in very white snow backgrounds, you must make a manual correction by
adjusting the histogram.
Sharpening To improve the edge details of an image, use the “Unsharp Mask
filter” in Photoshop. This can digitally refocus an image that has become
blurred from scanning or interpolation. A small over-estimation of the filter
effect can be diffused in the printing process; however, a large over-estimation
can give the image a hard, pixelated appearance.

Introduction 15
Ink cartridge preparation and alignment
Cartridge maintenance and alignment are key factors in printer performance,
which in turn affect colour, accuracy, and image quality. Use the following
recommendations to keep your cartridges in optimal working condition:
■Keep the printer wiping stations clean so that the heads stay clean.
■Align and check cartridges to make sure all nozzles work properly.
■To achieve the best possible accuracy, use a loupe to evaluate the registration
of test patterns.
■Re-align all cartridges when you adjust, move, or replace a cartridge, since
even small, one-pixel errors can affect both colour and image quality.

Loading media
You can use either roll media or cut sheets. The printer is set for roll media as
its default. To ensure straight paper loading and avoid skewing, hold the media
parallel to the platen line. Use the loading lines on the platen as a guide. The
printer has sensors which detect the presence of media and activate the feed
and take-up mechanisms.
The roll media core must have an inside diameter of 5 cm and a maximum
outside diameter of 15 cm (about 6 inches). If your media has an inside
diameter of 8 cm, use the core adapter provided. If you want to store prints on
the take-up roll, you will need to have extra cores available.
Caution: The Océ CS 5050/5070 printers (60” version) can use media up to
60" (1,52 m) wide. The media roll may be heavy, so have someone help you
to load it. Before printing, check that you have a take-up roll core available
that is the same width as the media roll core you are loading.
Attention: If your roll media has wrinkled or damaged edges, cut off the
damaged part of the roll prior to loading, to prevent the media from
jamming in the printer. Load only media with an edge that is perfectly
horizontal into the printer. Make sure not to leave fingerprints on the
printing side of glossy media paper.
Using the power media feed and take-up system
The power media feed and take-up system facilitates long, unattended print
jobs by automatically unwinding and rewinding media as prints are generated.
It includes a feed roll, a take-up roll, and sensors which prevent media from
touching the floor.
When the unit is first switched on, the feeder may turn for a few seconds. If the
take-up turns, it indicates that the sensor is blocked. Clear anything blocking
the sensor before proceeding.
