Oce ColorWave 600 User Manual

							'Relative colorimetric'
#
Relative colorimetric keeps an almost exact relationship between in gamut colors,
even 
if this clips out of gamut colors.
The
 relative colorimetric rendering method replaces the colors to align the old white
point 
(the location of the most pure and light white in a color space) with the new
white 
point and to keep the relative positions of the colors. The Relative colorimetric
rendering intent is advised for logos, spot colors or PowerPoint presentations, but
the loss

 of contrast can 
be a problem with photos and images.
Note:
If you generate a color scan-to-file job in TIFF format on an Océ TCS400,
an Océ TCS500 or an Océ TDS450, 'Relative colorimetric' gives the best
result. Chapter 8

							'Absolute colorimetric'
#
Absolute colorimetric is similar to relative colorimetric, but uses a different method
to handle the white point.
Absolute and
 relative colorimetric both keep gamut colors and clip those out of
gamut,

 
but absolute colorimetric also keeps the white point.
Absolute colorimetric
 is advised for "proofing" applications, that require a good
color match,

 but also emulation 
of paper white. As a result of that, white areas can
become yellowish,
 because the printer tries to emulate 
the whitepoint of the input
profile.
This 
setting provides the highest accuracy in rendering RGB colors into CMYK
colors,
 including rendering the source's white.
Note:
You can see the minor level of blue of the monitor background as a bluish
white in
 
the lightest tones of the printed output. A minor yellow tone can
occur in
 
the white tones of a PDF/TIFF original or an HP-GL type docu-
ment. Chapter 8

							What is an output profile?
The output profile is used to adjust the converted CMYK color space, depending on the
output device (via the Océ ColorWave 600 Printer Calibration Module) and the media
type you
 select 
(via the OMP Océ Media Profile file).
The 
output profile is applied automatically, but it is important that you load the correct
media on the Océ ColorWave 600 and that the correct OMP-file is available on the 'Océ
PowerM controller'

 or the 'Océ PowerM Plus controller '.
(see 

‘Manage the media profiles’  
on page 284)
(see
 ‘Download a media profile from the Océ web 
site’  on page 286)
(see
 ‘Upload a media profile’

							Color management settings in the Océ Express WebTools
Depending on the type of file you want to print, the Océ ColorWave 600 offers different
color-information conversions.
 You can select 
the color management settings, that give
the
 best results for the color-information conversion.
Open the

 'Preferences' - 'Print job defaults' tab to 
define the default color management
settings per
 file type ('Color management settings for HP-GL, HP-GL/2 and HP-RTL
files', 

'Color management settings for TIFF and JPEG files' or 'Color management settings
for PostScript and PDF files').
The 

Océ Windows ®
 Printer Driver and the Océ Publisher Select job submission applica-
tion 
offer the same color management settings, but now file type independent.
Note:
It is only important to know what the file type of your print job is, if you want to use
or must use the color management settings defined in the Océ Express WebTools. If
you

 define the color management settings in your Océ Windows ®
 Printer Driver or the
Océ Publisher Select job submission application, the color management settings are au-
tomatically assigned to the correct file type (the color management settings defined in
the Océ

 
Express WebTools are overruled). Chapter 8

							Color management settings and job submission
The way in which you submit a print job to the printer defines in most cases the file type
of the document. If you use a printer driver, the original file type will be changed by the
driver into a standard file type. The printer checks the file type of the document and
based on
 the file type the printer applies the default colour management settings of the
Océ 
Express WebTools.
If 
you use FTP or LPR to send a job to the printer, the file type is not changed. The file
is sent to 
the printer the way in which it was saved in the application you used to create
or edit the file. If there is no embedded color profile present in the document, the printer
checks 
the file type of the document and based on the file type the printer applies the
default color
 management settings of the Océ Express WebTools.
If 

you want to use the embedded color profile for your print job (for example, embedded
profile created with 
Adobe ®
 Illustrator) you can choose between 2 options. You can use
the
 WPD driver where you can 
indicate to follow the color settings managed by the ap-
plication. You
 can also 
send the job via FTP or LPR. If the controller can recognize the
embedded 
color profile, it will be applied. If the embedded color profile cannot be recog-
nized, the controller applies the default color settings managed by the Océ Express
WebTools.
The

 
table below gives an overview of the relation between the job submission method,
the file
 type and the color management settings #

							Priorities in the color management settings
When you want to print a document in color on the Océ ColorWave 600 the color infor-
mation that is defined in the files can be set in the different steps of the process from
document creation
 to document production. In order to get the best output results you
need 

to be aware of these methods to define the color information of the document you
want 
to print.
The color information that you can create in the various steps described below each have
a different priority. When you create a document that you 
want to print in color, the
priority of
 the color settings is also illustrated in the table below. #
Priority
Stages in the process of making a
 color print
1
Document
The color settings are already embedded in the document (only applicable
for PDF files).
2
Application
The 

color settings can be defined in the application that you use to create
or edit the document.
You can

 
set the following parameters in the application.
• Set 
color or black and white.
• Define the
 input profile, RGB input data or CMYK input data.
(see 

‘What is an input profile / 
standardization?’  on page 333)
You
 cannot define this for a PDF file.
• Define the

 rendering intents.
(see 

‘Definition of rendering 
intents’  on page 338)
Note:
You can only overrule the color settings of a PDF file with an
Adobe ®
 
application such Adobe Acrobat ®
 for example. 3
Printer drivers
The 
Océ Windows ®  Printer Driver offers color management settings.
You can
 
select the required color management settings in the driver or
you 
can indicate to use the printer's default settings. Make sure the color
settings do not conflict with the color settings that may be set in another
stage of the process. Chapter 8

The 
Océ Express WebTools offers 3 default paths for color settings,
based on
 the file type of the document:
• 'Color management

 settings for HP-GL, HP-GL/2 and HP-RTL
files'
‘
 'Color management settings for HP-GL, HP-GL/2 and HP-RTL files'
’

• 'Color management

 'Color management settings for TIFF and JPEG files' (RGB input)’  on
page 350
‘
 'Color management settings for TIFF and JPEG files' (CMYK input)’
on page 351
• 'Color management

‘
 'Color management settings for PostScript and PDF files' (RGB input)’
on page 352
‘ 'Color

 management settings for PostScript and PDF files' (CMYK input)’
on page 353
These 

settings are applied when the controller cannot recognize or detect
any 
color settings for the file to be printed.
Note:
It is advised to align the color management settings that have been made in the different
stages 
before you start the print job. The color space of the document and the settings
for the
 print have to match. This means 
that if you have set the color settings in more
than
 1 stage of the process described above, you must check if the color settings do not
counteract with
  each 
other. Chapter 8
