NEC Monitors Driver

This is a very difficult question to answer given the huge number of variables involved. Some general hints are given below:
1) Confirm that your display monitor and printer profiles are correctly installed and associated.
2) Confirm that Photoshop or other application being used is configured to use these profiles. You should never use the display monitor's ICC/ColorSync profile as the color workspace.
3) Confirm that you are using the correct printer profile for your particular printer, and the type of paper being used. Be aware that print colors change drastically depending on the paper being used, so it is vital to obtain and use the correct printer profile for the combination of printer, inks and paper.
4) If possible use a printer profiling package to generate an accurate profile of your printer and paper combination.
5) Most inkjet prints will change color as they dry. Allow sufficient time for drying before evaluating color.
6) Make sure that any colors you are evaluating are not either outside of the display or the printer's color gamut.
7) Make sure that you are using Photoshop or other application correctly in order to do a 'proof colors'. Note that most applications no not show a 'printer simulation' or 'softproof' by default and these modes must be specifically selected. See the documentation for your imaging application and other resources for more information on this complex topic.
8) Make sure that the printer's control panel is correctly configured when printing. In some cases it may be necessary to disable the color management in the printer driver. See the documentation for your printer and other resources for more information on this complex topic.
9) Review the lighting conditions being used to evaluate your prints. The lighting should be consistent and of known characteristics. The use of a lightbox is highly recommended. The area surrounding your workspace should ideally be neutral in color and relatively dark to avoid influencing visual judgment. Daylight should not be used to evaluate color if possible because of the huge variation in color during the day.
10) Depending on the lighting conditions, it may be necessary to choose a different Intensity and/or White Point when calibrating the display using SpectraView.
