I shoot with Nikon D7100, D810, and Galaxy D7 (in a pinch). I use a Dell computer with a 24" Dell monitor and use HP Photosmart 7520 as my primary printer. When I view photos in Lightroom, the colors are bright, beautiful and appear true to the photographed scene. But when I print, the printed picture has color shifts and appears drab. Am I right in assuming that the monitor is probably OK, but the printer needs to be calibrated? If so, what do I need to do?
Common color mis-match issues:
• Uncalibrated Monitor, or "too bright" calibration aims
• ICC profile mis-match (using Adobe RGB or ProPhoto RGB working space to interpret an sRGB image, for instance)
• Improper image profile conversion
• Double profiling (driver and application both apply the same profile, or worse, two different ones)
• Trying to print in 16-bit mode with an 8-bit printer driver
• Wrong, or NO printer/paper/ink profile enabled
• Clogged nozzles in one or more colors
• Using an office-grade printer for photos
• Partially color blind color corrector
• Lack of sleep, severe stress, pregnancy, recent exposure to bright light, too much caffeine, mind-altering substance consumption...
Most of these situations can be avoided with a little thought, care, foresight, and effort. Color management is a system that starts at the camera, ends with the print.
In a raw image workflow, the "profile" is part of your computer operating system or application software. Microsoft, Apple, and Adobe (and your camera manufacturer) provide the conversion parameters that allow you to convert an image from raw data to a "working space" such as ProPhoto RGB or Adobe RGB. The working space profile is then converted to your monitor profile for viewing, or to your printer profile for printing, or to sRGB for the Internet and photo labs, or to Adobe RGB for high end labs and service bureaus or commercial printers. Along the way, you can adjust it within the limitations of your monitor.
In a JPEG workflow, the profile is set at the camera to sRGB or Adobe RGB. Adobe RGB is not recommended for office-grade equipment, which can't handle the wider gamut. The image is converted to the working space profile when it is opened. The working space profile is then converted to your monitor profile for viewing, or to your printer profile for printing, or to sRGB for the Internet and photo labs, or to Adobe RGB for high end labs and service bureaus or commercial printers. Along the way, you can adjust it within the limitations of your monitor.
Monitors must be calibrated with a colorimeter or spectrophotometer. From the calibrated state, the monitor calibration software then creates an ICC color profile and stores it in the operating system. It is the profile, working WITH the calibrated state of the monitor, that provides a standard color viewing environment. That's why it is important to NOT TOUCH the monitor calibration controls after installing the profile, UNLESS you intend to re-calibrate and re-profile.
Getting prints that are very close, pleasing matches with your monitor is possible, but there are many "switches to set" to get there.
