These two images look different when using the same photo, the printer image colors and tones don't match what shows on the screen. I did some research and found there's software I can buy to make the printer image match the screen image. For over $700!
Does anyone know what causes the discrepancy and why? Is there a better solution than the one I found?
My printer is an HP Officejet Pro 8630. I used to have an HP Photo printer but it showed the same effect.
This is a very common problem.
You need to calibrate your computer monitor. Most monitors are by default way too bright and don't render all that accurate colors. This causes you to misadjust your images too dark and with the wrong color settings.
A calibration device and it's software help solve the problem. This doesn't need to cost anywhere near $700! Two popular and effective devices are X-Rite ColorMunki and Datacolor Spyder, some versions of which cost as little as $100 to $150. There are more advanced versions that cost more, of course. Check to see which can do what you need.
If you do much printing, this is a good investment because re-calibration needs to be done periodically. Over time and with use, monitors gradually lose brightness and shift color rendition. Some people calibrate very frequently... weekly or even daily. I do so monthly and that works for me. But, to give you some idea, when I first got my current monitor some 7 o 8 years ago I had to adjust the brightness down to 20& (sorry, don't remember what the default setting was). Now after using it all those years, when I calibrated it most recently it was set to just over 50%. That's how much it's changed over time.
If you print a lot, a calibration device will essentially pay for itself in savings of ink & paper, or the cost of re-doing prints if you send them out for printing instead.
The way these devices work is first testing the brightness of your display and helping you set that to a workable level. Next the calibration software displays a series of test patches of various colors, which the device measures. The information gathered by this process is used to create an accurate color profile for the monitor. This also changes gradually as the monitor ages and needs to be re-done periodically. The changes in color rendition aren't as obvious or easily measured for comparison, as the brightness level. But, depending upon how advanced a device you use, there may be sample images that you can toggle and compare, and/or charts of the color rendition that you can compare and save.
Depending upon your workflow, you also might improve print accuracy by installing an ICC profile that your image editing software can be used with one to "soft proof" your images. This isn't perfect (can never be, since a monitor display is back lit and has a narrower dynamic range than a reflective print on paper)... but it can be pretty close. Most printer manufacturers build profiles into their driver software you can select among, which might work well so long as you use their inks and paper. But if you use different brands of paper and ink, you may need to see if their manufacturers offer profiles for your particular printer. If not, custom profiles are possible. Some of the most advanced versions of calibration devices can be used to make them... or you can purchase a custom made profile from a supplier.
Another important consideration is where you actually view your monitor screen... ambient light conditions effect how things appear on-screen. For that reason, it's usually best to set up somewhere that lighting is pretty consistent. I also made a 6 inch deep "hood" for my monitor out of black foam core board to keep oblique light off it. It's fastened with Velcro and I cut a small panel in it that can be removed when I need to run the wire to do a calibration. Variable lighting conditions are one reason that laptops are less useful for image editing than a permanent work station where lighting can be controlled and kept more consistent.
You also have to set up the printer correctly. Or it may be better for your image editing software to control the color rendition. Some software can do that... others can't.
Hope this helps!
