Printing with Océ CS 5050/5070

The Océ CS 5050/5070 wide-format inkjet printers can reproduce graphics up to the length of a roll of media. Large format colour printing combines the technical sophistication of the Océ CS 5050/5070 series with the unique qualities of Océ proprietary inks and media (coated canvas, vinyl, film, paper, etc.)

Introduction 11

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 pri nting he avy r enderin gs, maps, or art gra phics, ch oose 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.
12 Océ CS 5050/5070 User Manual
CD images in TIFF or EPS format of 28MB or more are preferable for high
■
quality prints. A v oid 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.
■
When using LZW, the compression factor will be very low on photo
Note:
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. V ariations 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.
Introduction 13
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 (insuff icient 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, deta i le d i mage s intended for close vie wi ng
■
100 dpi for vie wi n g fr om a sign ificant 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, remov e 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 suff ic i ent for properly expo sed images. However, in very dark night sc e nes or in very white snow backgrounds, you must make a manual correction by adjusting the histogram.
Sharpening
T o improv e 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; ho wev er , a lar ge ov er-estimation can give the image a hard, pixelated appearance.

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.
■
T o achie ve 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.

Using the control panel

Before printing, make sure that you are familiar with the start-up checklist and the control panel’s main menu functions.
Start-up checklist
To start the CS 5050/5070, check the following:
Be sure that the power cord is plugged into the wall socket.
■
Be sure that the printer connects to your computer using a parallel cable.
■
Turn on the printer before attempting to print.

Loading media

You can use either roll media or cut sheets. The printer is set for roll media as its default. T o ensure straight paper loading and avo id 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:

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, i t indicates that the sensor is blocked. Clear anything blocking the sensor before proceeding.
