I have the Epson P800 printer and love it. However, I have a problem with the image on my desktop computer coming out darker when printed. I post process the image starting with LR and move it to Photoshop where I finish the post process then get ready to print that image. I have had to increase the brightness on the page setup for the printer and hope for the best. Each photo when printed may require anywhere from +9 to +15 on the printer page setup and that just doesn't work so good to me since printer ink is so expensive. Any ideas on how to remedy this dilemma?
My Dell computer monitor brightness is set to 51 and the contrast at 50 if that gives any extra info on my problem.

The MONITOR is the core pivot point of the entire system. When prints are too dark, 99% of the time, the monitor is either too bright, or not properly calibrated and profiled. Here are some pointed questions that will get you to the solution.
After careful calibration and custom ICC profiling, if you use the soft proofing feature of your software for final image adjustment before printing, it is entirely possible to have what you see on the monitor almost exactly match what comes off the printer.
Of course, monitors are additive color devices and printers are subtractive color devices, so what you are trying to do is simulate reflected light with a transmissive device. The color gamuts of the monitor, printer, ink, and paper do not match exactly. So the need for *color calibration* (linearizing the three color channels so they reproduce gray at every shade from white to black) and *ICC profiling* (mathematically describing the color capabilities of one device so they may be converted to the capabilities of another device, within reason) is urgent.
Is your monitor capable of displaying at least 100% of the sRGB color space, and preferably over 98% of the Adobe RGB (1998) color space? If not, you need a new monitor.
Does your monitor have individual controls for backlight, brightness, contrast, gamma, and color temperature?
Do you own and use religiously a colorimeter and software or spectrophotometer and software calibration and custom ICC profiling kit from Datacolor or X-Rite? Alternatively, did your high end monitor come with its own calibration device and instructions?
The $150 to $300 you spend on a calibration kit will MORE than pay for itself in paper and ink savings over the life of the printer. Even if you only use outside labs, if you calibrate and profile your monitor, and get the lab's printer profiles to use as proofing profiles, you will get prints that satisfy, almost every time.
Have you set the following parameters in the calibration software?:
> Color Temperature 5800K (5000K to 6500K, depending on the software's recommendation)
> White Point 80 to 120 candelas per square meter (cd/m^2) (105 cd/m^2 is a common lab aim)
> Black Point 0.5 cd/m^2
> Gamma 2.2
Is your monitor in a dimly lit room with just one 13-Watt, 5000K, 91+ CRI lamp bounced off the ceiling from behind the monitor?
Do you have a print evaluation box lit with the same 5000K lighting matched to the brightness of your monitor? (Meter EV 9.5 at ISO 100 off a gray card placed where an 8x10 print would be viewed.)
Is your computer desktop set to medium dark gray?
Is the area around your computer nice and drab — preferably gray with no bright colors in your field of view?
Are you sure you are not double profiling the image? Let EITHER the software OR the printer manage color, but not both. Disable printer color management when using third party papers.
If you are using third party papers with Epson ink, download and install the paper manufacturer's printer-model-and-paper-specific profiles for the papers you use, and install them. Choose the paper profile in your software, and the paper type in the printer driver, correctly.
I know that's a mouthful to swallow, but it does work. I set up a system like this in a huge portrait lab a while back. We kept nine reference monitors calibrated to each other and to a master printer. We had close to 80 different printing devices in the lab, from mini-labs to plastic ID card printers to Epson inkjet wide format printers, to electrostatic printers (color copiers with raster image processors plugged into them). We didn't have issues with dark prints.
