How can you change the appearance of a digital image without changing the numbers that assign the color values? Change what those numbers mean by changing the image’s ICC profile. Using abstract or synthetic profiles, you can make massive changes to an image with little to no cost, changes that ordinarily would cause big problems using standard methods, such as posterization and noise. It’s a practice known to color geeks and few others. When you’ve got a big job to do, it can get you out of a pinch in a hurry.

In most cases, we think of using color management to accurately match colors when moving between different color spaces; ICC profiles are used to describe different color spaces and to make precise transformations to values moved from one to another to maintain consistent appearances. In very rare cases, when profiles are assigned to image files without a color conversion, the appearance of the image changes; values stay the same, but their meaning changes, so the image looks different. So when you use this unorthodox method of color adjustment, you get a change in appearance without changing the values in the file, and this is particularly useful when you want to pay a very small price for making very big changes.

Am I saying that ICC profiles are used to change values so the appearance stays the same? Yes. Am I saying that a color space is just a recipe for color, and that there are many different RGB recipes? Yes, but while they’re the standards, sRGB, ColorMatch RGB, Adobe RGB (1998) and ProPhoto RGB are just a few among many.

With just a little experimentation, you’ll find you, too, can make big changes to your images and pay a small price using synthetic profiles. Using synthetic profiles is color adjustment without editing values; they change no values, but they do change the meaning of those values—and thus their appearance. Don’t believe it? Check your histogram when you assign a profile. You won’t even see it move! It’s kind of unbelievable. Try it. See it with your own eyes. You’ll quickly become a believer, too.

Learn the steps you need to take to make your own synthetic profiles …

Profile Your Printer

December 21, 2011 | 2 Comments |

Prints made with default (left) and custom (right) profiles compared.

Good printer profiles help make good prints. Better printer profiles help make better prints. So, logically, you’ll want to use the best printer profiles to help you make the best prints.

How do high quality printer profiles contribute to print quality? A good printer profile helps render optimum shadow and highlight detail, gradation, neutrality and graybalance, as well as color rendition and saturation. (Remember, printer profiles characterize the combination of a printer’s hardware, ink, media setting, and the substrate you choose. You’ll need different profiles for different substrates on the same printer.)

How can you get good printer profiles? Look to three primary sources. One, use profiles provided by printer manufacturers; they’re free. Two, hire a printer profiling service; profiles cost approximately $100 each. Three, make printer profiles yourself; printer profiling systems run between $400 and $1000. (Profiles supplied by substrate manufacturers are of uneven quality; a few are good, many are bad.)

Which solution is right for you? It depends on both your printing conditions and needs.

If you’re using substrates supported by the manufacturer of your printer, try using the profiles they provide first; they’re often quite good. Years ago, Epson raised the bar on the quality of printer profiles provided by manufacturers. The highly sophisticated routines they use to produce their printer profiles processed by supercomputers are truly state-of-the-art. It’s arguable that you can produce better profiles, even with the most sophisticated profiling solutions available. Their profiling routines factor in subtleties like dot structure or screening frequency. One of the reasons a solution like this works is because the technologies and manufacturing standards they use are so consistent that the unit to unit variation between individual printers of the same model is extremely low. (It’s less than a Delta E of 1 or the minimum variation the human eye can detect.) Some, printer manufacturers, like Canon, provide a large number of profiles for substrates made by other companies; their quality is generally quite high with only a few exceptions. Other printer manufacturers, like HP, produce self-profiling printers. They need to be self-profiling, as the state of the printer is constantly changing; when nozzles clog, new nozzles come on line; when ink cartridges are swapped nozzles are replaced. One advantage to a system like this is you can quickly profile a new substrate on a printer with no additional equipment. The quality of the profiles is often good, but there will be times where you’ll want to improve upon it.

No manufacturer provides a comprehensive set of profiles that will cover the entire spectrum of fast-evolving substrate industry. A little experimentation with new media is advised, sometimes a lot. If you experiment with many medias or use more exotic substrates, you’d be well advised to have someone make custom profiles for you or do it yourself.

One critical aspect of color management has nothing to do with either hardware or software. It’s the environment you work in. Control your environment and you’ll control the color you see. Desktop, walls, decorations, fashion, viewing light, secondary light sources, ambient light – it all matters.

Keep It Neutral

Color influences color. This is sometime physical, when filtered or reflected color alters the appearance of another. This is always perceptual, when our eyes adapt to the presence of multiple colors. That’s right. Surround one color with another color and you’ll experience the color differently. You can’t measure this change in the physical world because the change takes place inside your eye/brain. Simultaneous contrast is a perceptual adaptation that you can’t turn off, but you can be aware that it’s happening, understand how it’s influencing you, and minimize it’s effects.

How? Surround yourself with neutral colors; they influence our experience of other colors least. Neutral colors produce the least contamination and the least adaptation. And, medium gray values produce the least brightness compensations of all neutral colors.

You may be tempted to make the appearance of your computer desktop colorful and lively. That’s fine for many non-color-critical tasks. However, when you’re adjusting color, make your desktop neutral. You won’t be able to see the color you’re adjusting accurately unless you do. If you don’t want to change your desktop use Full Screen mode, to hide the desktop and surround your image with a neutral color. (One downside to this is you’ll only be able to view one image at a time.)

Walls and decorations of any significant area should be neutral in appearance too. Make walls and decorations neutral. For the purposes of controlling your environment, any neutral color is better than a saturated color. You could opt for white, gray, or black. Don’t opt for designer whites, grays, or blacks, which contain trace amounts of hue and saturation that can still influence your perception enough to be significant. Choose neutrals. (If you’ve got a favorite image (poster, photograph, painting, etc) that’s colorful, position it out of your field of vision while you’re adjusting color.)

Don’t forget fashion. Wear neutral colors. If you wear bright colors, they’ll influence your perception too, especially if light reflects off of them and onto your surroundings or images.

Light It Well

The most important thing to control in your environment is light.
After all, light is what produces your sensation of color.

Viewing light, secondary light sources, ambient light

It stands to reason, for viewing color accurately, you want white light not filtered or colored light. (Don’t wear sunglasses or tinted glasses when adjusting color.) But what many people don’t consider is that not all white lights are created equally.

You’ll want to consider the amount of light – measured lux. It’s better to have too much light than too little light; colors will appear dull if you don’t use enough light; just don’t produce glare or make viewers squint. A CRI of 90 or higher is recommended.

Next, consider the color temperature of light – measured in Kelvin degrees. While 5000K is the industry standard (most viewing boxes and printer profiles are built for the 5000 K standard), in real world situations very few people view printed color under 5000K light. More typically, prints are viewed in galleries and museums in some form of halogen (3300K – 3800K) or in homes under tungsten (2800K) with a mix of daylight which varies with time of day, weather, and season. Viewing light for the end user is often highly variable. So, what do you do? Make prints for a specific lighting condition if practical. Otherwise, standardize on a viewing light temperature that can be least adversely affected in as many real world situations as possible. More people prefer the taste of 3600K than any other light temperature.

Finally, consider a light’s spectral distribution – smooth or spiky when graphed. White light can be mixed with different combinations of colored lights. This rarely affects the appearance of neutral colors, but it may have a significant affect on saturated colors. Light sources that contain only a few spectral frequencies (spiky or limited) will increase the apparent saturation of the colors they contain and decrease the apparent saturation of the colors they don’t. Light sources that contain all spectral frequencies (smooth or full) will render all colors without bias and won’t produce relative saturation distortions. Full spectrum light (sunshine, tungsten, some halogen) makes colors appear clearer and more saturated. (See my free ebook review on Solux lighting at www.johnpaulcaponigro.com.)

Secondary light sources should also be considered. Avoid backlighting; don’t position your monitor or proofs/prints with bright light sources behind them. Eliminate reflections; use blinds for windows and reposition lights that reflect off monitors. Reduce glare and flare as much as possible. New colorimeters (like Ax-Rite’s i1Display Pro and ColorMunki Display) compensate for these factors during monitor calibration and constantly measure and adapt to changes in these factors over time. Make your viewing experience as easy as possible. If you’re serious about color, you’ll plan to look a lot.

With a few careful choices you can make sure your environment supports your efforts to see and adjust color precisely everyday. It’s time well spent. Without this attention to detail, even the most sophisticated color-management systems may be compromised. With this attention to detail, you can rest assured that you’ve done everything physically possible to control color. In a controlled environment, your color will truly shine.

As a rule, always softproof an image to determine a rendering intent and make printer/substrate specific adjustments to a image file before printing it.

You can get Photoshop to display an image the way it will appear when it’s printed, before you print it, by softproofing an image. If you softproof before you print, you’ll get your best first proof or maybe even a finished print.  Not to be confused with a hard proof or physically printed piece, a softproof uses an ICC profile to create an onscreen simulation of an image as it will appear when printed.

Wait. Haven’t you already done this by calibrating and characterizing your monitor with a colorimeter, choosing an editing space along with color management policies in Photoshop, and specifying the right profile for a printer/paper combination with your printer driver? Almost. Doing these things ensures that all of the different color behaviors of the devices you’re using are accurately described and that color conversions are handled precisely, but it doesn’t ensure that you will see exactly how an image will look when printed. Without softproofing, you see how an image looks on a monitor. To see an image on a monitor with the appearance of how it will look when printed, before you print it, you need to take the final step of softproofing the image. This simulation won’t change your file, just it’s appearance. Once softproofed, if you choose to, you can make output specific adjustments to your file before printing to get a better first print.

If you want to display your images accurately, and make sophisticated decisions about how they will or could look, calibrate your monitor with hardware. Monitor calibration is a must. It’s not optional. It is easy. You need a device to do it well.

The visual comparator method (using your eyes to approximate an appearance on screen) is too fraught with inaccuracies and inconsistencies to be relied on. Instead, use consistent, accurate, objective hardware and software. Colorimeters don’t have favorite and least favorite colors, don’t have color deficiencies, don’t get fatigued, don’t drink caffeine or eat sugar, don’t change over time or adapt to their environments, and don’t have emotions. You do. All of these can affect your perception of color at one time or another. Colorimeters are in a stable state. You’re not. So when it comes to making sure that your monitor displays color as accurately as possible, use a colorimeter.

While some colorimeters, and the software packages that ship with them, are better than others, most colorimeters are good. Unless it’s defective, any colorimeter is better than none.

Spectrophotometers can also be use to calibrate monitors. What’s the difference between the two? Unlike a colorimeter, a spectrophotometer has it’s own light source that can be used to make printer profiles. Spectrophotometers can do more. They also cost more.

There is a difference between calibrating and characterizing devices. Calibrating a device is changing its state, like setting the brightness of a monitor. Characterizing a device is measuring and mapping the color capacity of a device or building an ICC profile to describe it. Most of the process of monitor ‘calibration’ is actually ‘characterization’.

Calibrating and characterizing your monitor is a simple process. Use the profiling device and software of your choice. (I personally use X-Rite products.)
