Color laser printer prints colors much darker than screen colors
I want to be able to print the standard basic colors**
exactly the same way that they appear on the screen. A specific instance of this is that cyan*** is printed as a much darker shade of blue than appears on the screen. I have found this exact same problem exists across several laser printer brands and models, and is likely an issue with all laser printers. How can I correct this problem? ** (Defined by combinations of RGB values at their maximum value of 255 and half of their maximum value of 128) . *** cyan---Red(0), Green(255), Blue(255) |

But don't get your hopes up -- it is always going to be a hit-or-miss proposition -- screen and paper are just too different for it to be otherwise. And get used to the requirements that you never as much as adjust the brightness or contrast of your monitor to make it look "better". And get used to touching up the settings regularly. And be prepared to viewing your prints only under a single well-controlled lighting condition and source. There are many articles online that tell you what to do. This is a very low-level introduction: http://www.pcworld.com/article/11007...r_monitor.html If you are serious about matching colors then you'll need hardware assistance in the end: http://spyder.datacolor.com/index_us.php -- John McGaw http://johnmcgaw.com -- John McGaw [Knoxville, TN, USA] http://johnmcgaw.com |

As John mentioned, it's called calibration, or a more crude way to do it is pick whichever device is off from what you perceive the right color, and correct that device first. For example, if the screen is too dark, adjust that, or the printer output too light, that instead. I have found this exact same problem exists across several laser printer brands and models, and is likely an issue with all laser printers. How can I correct this problem? Then it seems likely your monitor and/or video driver output settings are set wrong. |

It looks like there is no possible combination of colors that can produce the bright shade of blue represented by RGB(0, 255, 255), and the same thing goes for the bright shade of Green represented by RGB(0,255,0). My printer had a series of test pages that provided 288 shades of blue and 288 shades of green, and none of these colors matched the screen. |

My printer had a series of test pages that provided 288 shades of blue and 288 shades of green, and none of these colors matched the screen. FWIW, RGB(0,255,255) is really not "bright blue" (or at least it shouldn't be) -- it is really 100% saturated cyan. As you've experienced, there is a limit to the color gamut of every device. Expecting a perfect overlap between a light-emitting image such as a monitor and a light-reflecting image such as a printed page is not realistic. About the best you can hope for is a calibration between the two that will allow you to predict roughly how the printed page will look. But be prepared for any match to change every time you change paper or toner. This is the bane of every person who does photos or graphics in print. And it is probably why there are multiple hardware/software solutions on the market with some of these solutions being insanely expensive. -- John McGaw [Knoxville, TN, USA] http://johnmcgaw.com |
