Calibrating and Profiling the Displa\f
If  more  than  one  supported  display  monitor  is  connected,  select  the  display  to  be  calibrated  from  the Display 
listbox. Note that each display has an independent Target.
Click  the Calibrate  button  to  start  the  calibration  process.  The  software  will  provide  instructions  for  placing  the 
calibration sensor on the screen and provide updates as the calibration progresses.
Once  the  calibration...

Using ICC/ColorS\fnc Monitor Profiles
The ICC/ColorSync monitor profiles generated by SpectraView are used to inform the Color Management System 
of the color characteristics of the display monitor.
Color  Management  Systems  use  this  information  to  determine  how  to  display  images  on-screen.  Depending  on 
the  image  editing  software  package  being  used,  profiles  for  printers  and  scanners  can  also  be  utilized  to  create 
accurate image...

Calibrati\fn
Question 1: How often do I need to calibrate my monitor?
Answer: The answer will depend on how critical a color accuracy is necessary, how long the monitor is used per 
day,  environmental  conditions  and  the  characteristics  of  each  individual  monitor.  Some  users  working  in  highly 
critical color applications may calibrate their displays every couple of days. Others may only need to do it once a 
month.  The  recommended  and  default...

display.
Question  4:  I’m  trying  to  match  my  display  to  my  prints  in  order  to  soft  proof,  however  after  calibrating  using  a 
standard Target white point such as D65 or D50, the screen still appears too pink/magenta/green compared to the 
print. What can I do to make them match?
Answer:  Depending  on  many  factors  such  as  the  lighting  conditions  used  to  view  the  prints,  paper  type,  and 
the  printer  profiles  used  for  the  soft...

Question  5:  Each  time  I  calibrate  my  monitor  I  receive  a  different  Delta-E  result.  Should  I  recalibrate  again  if  I 
receive a value that is high?
Answer: For Delta-E values of less than 2 there is almost certainly no need to recalibrate. For values higher than 3 
it is important to understand what the cause is, and if it is significant. 
The  calibration  and  adjustment  process  has  inherent  variability  due  to  many  factors  such  as  the...

Installati\fn and Setup
Problem: Calibrate button is disabled.
Solution: The calibrate button is disabled for either of the following reasons:
•	No supported calibration sensor was detected.
•	No supported display monitor was detected.
See the following sections for further explanations. 
Problem: No supported monitor was detected.
Solution: 
•	Verify that the display monitor connected is a model supported by this version of SpectraView II. Check if 
a newer version...

Problem: No supported calibration sensor was detected. 
Solution: 
•	Try reconnecting the calibration sensor and click the Auto Detect button in the Preferences dialog 
to re-detect the sensor. 
•	It may be necessary to close and re-launch the SpectraView application. 
•	(ÿ Windows) It may be necessary to install the drivers for the color sensor device. Note that only 
the drivers for the X-Rite iOne devices are installed by the SpectraV iew setup application....

application icon and selecting “Run as administrator”. This process needs to be done once each time the 
user who created the last ICC profile for the display is changed. 
•	This issue may also occur if another application is currently using the ICC profile. For example if the 
Windows Advanced Display Settings control panel is open, the ICC profile may be locked. Be sure to close 
any applications that may be using the profile.

Using SpectraVie\b \bith NaViSet Administrat\fr ( ÿ Wind\f\bs versi\fn \fnly)
The  SpectraView  II  software  integrates  with  the  NEC  DISPLAY  SOLUTIONS NaViSet Administrator  software  to 
provide remote administration of  the display monitors on networked machines. NaViSet Administrator will report all 
of the current SpectraView settings and the current calibration status within the NaViSet Administrator Console 
application. 
When  using  the Single...

The SpectraView II software includes several test patterns that are useful in evaluating the monitor calibration. It is 
also good practice to use the Test Patterns to quickly visually verify the integrity of the calibration. 
A  pattern  based  on  the  DICOM  TG18-GC  test  pattern  has  a  number  of  useful  features  that  allow  very  detailed 
analysis  of  the  monitor  grayscale  performance  in  one  pattern.  The  main  features...
