Monitor calibration is now universally seen as an important part of quality image making. In the photographic domain, it's fairly rare to see anyone doing serious work without a monitor calibrator. Even Graphic Designers who are often surprisingly reluctant to move on from the primitive days of Pantone books and CMYK, are finally getting the message that calibration is the way to go.
Put simply, to do serious, reliable, accurate digital imaging work it is fundamental that you can see and assess on screen colour accurately. Your screen and perception of it will influence profoundly every single image you make and calibrating it is the bare minimum you should be doing to keep it running OK.
However, it's all too common to see people who own a calibrator and have given up using it because they encounter problems at some point (most likely a failed calibrator), or bought a calibrator in 2002 and dig it out once a year assuming it will be bringing them accuracy. It won't! Unfortunately, calibrators can and do fail on occasions, and do also simply wear out.
Seen from a general scientific standpoint, calibration equipment generally requires re-certification on an annual basis to be considered accurate. However, with consumer level devices (those in the $0 to $600 range), the cost of recertifying these devices is prohibitive. So it's generally not offered as a service.
In practise, the cost of owning a calibrator is between about $50 and $100 a year across its minimum lifespan of three years - which remains a very small price to pay for accuracy and reliability.
In practise, after long and diverse experience at Image Science, we have come to believe that three years is about the length of time you will reliably get from a good monitor calibrator. After three years, you may encounter problems, and it is likely the accuracy of your calibrator will drop off.
There are a number of reasons for this:
In practise if you imagine a minimum three year life span, this means the cost of ownership for a calibrator is between about $50 and $100 a year across the three years. It remains a very small price to pay for accuracy and reliability.
If you're a professional, think what one stuffed up job could cost you and you will immediately see that calibration pays for itself on job one. If you're a hobbyist, then it's more about saving wasted time than anything else, and getting the results that you want.
Warranties are 12 months though, and they won't move on that unfortunately. We have long argued with them for more, but as yet none of the makers have moved this boundary unfortunately. We live in hope - but most do last 3+ years in practise so this is usually more of a theoretical concern than a practical one.
In general, whenever you replace your monitor, you should discuss with us whether or not your calibrator will still be a good match for your new system. Also, if your calibrator is over three years old, it may be time to consider an upgrade.
Your monitor calibrator is out of date and pretty much guaranteed to be doing more harm than good if you are using an:
If you have moved to a wide gamut monitor, or LED backed monitor, you should replace your calibrator if using an older model, as they were not designed to accurately read these monitors. So replace if you are currently using an:
If you are experiencing any of these issues, you should be looking at upgrading your calibrator:
If you have an older monitor calibrator, or one that you think doesn't work with your current operating system or monitor there's often a solution to your problem. A lot of people encounter issues calibrating their new wide gamut monitors with older calibrators, or finding drivers when they move to a new version of their operating system - for instance Mac OSX.
There is an excellent open source colour calibration system called argyllcms. On top of this, a second project called dispcalgui adds a very good user interface for monitor calibration. It's compatible with a long list of sensors, all the common ones, and on most operating systems, such as Linux, OSX and Windows. They provide extensive information through their website so before you toss that calibrator in the bin - give it a go!
Monitor calibrators at the consumer price level are a relatively new product development, with the Spyder3 and i1Display 2 being the first serious stabs at solving monitor calibration at a reasonable price. Like most early generation products, it's clear now they had some teething issues.
It's also fair to say the developers could not really have anticipated the fierce pace of monitor development. The shift from CRTs to LCDs was surprisingly swift in the end, and now new backlighting and wide gamut technologies are coming to the market very quickly.
The i1Display Pro has a sealed filter design and is more programmable than previous devices. In theory this should mean it has significantly greater longevity. Firmware can be tweaked to cope with changes in monitors and the filters should last longer, but that remains to be proven as they're still relatively new devices in 2013. However, the i1 is an amazingly fast, accurate and quick calibrator with current monitors and we certainly recommend it highly.
If you still think replacing your calibrator on a three yearly basis is
too much, from a cost or environmental perspective, then consider using a
Spectrophotometers, although more expensive initially, do tend to have very long life spans. - particularly those with an LED light source (pretty much all of the current models), which tend to be very stable. This means that devices like the ColorMunki (available in a Photo or Design optimised version) last much much longer than their colorimeter type cousins. They are also much better at coping with changes in backlighting and gamut technologies, as they measure the complete visible spectrum.
We have found spectros are often still reliable are 10 years or more. This means the cost of ownership of something like a ColorMunki will be $50/year or less over time, and you get printer profiling and spot colour measurement as extras as well.
The caveat is that spectros are not as good at calibrating monitors
as the best colorimeters like the i1Display Pro. They are not awful, but
they are a bit weaker at measuring shadows. So overall for the best
monitor calibration we do still recommend a well-kept and relatively new

...I worked with Image Science a few times in 2014 for my Australian exhibitions and I have always appreciated the incredible knowledge and level of customer service you have provided. Your Website was already a truly formidable resource but after I saw the redesign just now, I'm completely amazed and I just wanted to let you all know that you've done a truly wonderful job of it. It's so nice just to stare at it and I look forward to exploring it all further...
