Selected FAQ

The colors of my image on my monitor do not match the output from my printer. What is wrong?
A monitor displays color by transmitting red, green and blue (RGB) light into your eyes. A printer uses existing light to reflect cyan, magenta, yellow and black (CYMK) light into your eyes. It is virtually impossible to have these two different color types (transmissive and reflective) match perfectly. Also, due to its transmissive nature, the monitor is able to display a much wider range of colors than a reflective product, such as a piece of paper with ink on it.

Secondly, most monitors are not calibrated for correct color display out of the box; they have to be calibrated to produce accurate colors. Adobe Photoshop includes a basic monitor calibrator to do this; the Adobe Gamma utility. If you have Adobe Photoshop, this utility can be found in the Control Panel in Windows.

Also, what type of color matching system (CMS) are you using when printing your image? The color matching system can greatly affect the output color of your image. For information on how to use the various color management systems available, please check the CMS user documentation or the web site of the manufacturer.

The colors produced by DuraBrite inks may look slightly different than those produced by ordinary dye-based ink. Due to the nature of pigment inks, lighting conditions can affect the appearance of printer output. For example, the colors in a print viewed in daylight may look different when viewed under tungsten lighting. Your printer software was designed to represent color accurately when prints are illuminated with a D50 (daylight) light source.

Some parts of your print are not as glossy as others. Because of the nature of pigment inks, the degree of gloss may be uneven on glossy photo papers. Surface gloss decreases with greater pigment saturation.

To ensure that the images your Epson Color printer produces are as close as possible to the images displayed on your monitor, you should do the following:
  • Calibrate your monitor
  • Experiment with various color management systems
  • Try using the ICM setting
To print a file saved in CMYK (cyan, magenta, yellow, and black) format with accurate colors, you first need to convert the file to RGB format. Your printer software automatically converts RGB files to your printer’s 4-color CMYK format. To print with the correct colors, convert any CMYK-format input files to RGB format before printing. For the best results, create your original print files in the RGB color space.
