If everyone took a few minutes to make sure that their scanner outputs sRGB images, then the color accuracy of images posted here would be greatly improved.


Color adjusting a monitor in the day of VGA schemes is a little more complicated than that. Even at Pixar, where they live and die on colors and computer monitors, all monitors aren't the same. Suffice it to say that color on monitors is adjustable...and is adjusted incorrectly on almost every one of them.

AnthonyUK, Don, and Buck49 this thread wasn't intended to address color calibration issues. I will soon start another thread to further address that issue. This poll/thread was meant to highlight that many scanners do not create scans that utilize color profiles that are common for all computer users. sRGB is a color profile that is an Internet standard and is what I hope to encourage all of us to use.

You don't have to understand what it is. Hopefully the results of the poll illustrate that there is an issue concerning it. I only ask that we all take a few minutes and adjust our scanners to output that particular type of image. Above I provided a link to a free online tool that will tell you if your scanner outputs sRGB images or not: http://regex.info/exif.cgi

As for changing the settings of your scanner to output sRGB, one can google "scanner model XXX-YYYY color profile setting" to figure out how to do so. Above I also stated that anyone is welcome to email me for help.

For a future thread, I will try my best to explain that only input device calibration is necessary, i.e. scanners. Regardless of scanner calibration, universal adoption of a single color profile will greatly improve color comparison between users.

My computer screen passed the color test. My problem has always been that the printout of the color on the screen is so different from the screen color, it looks like it would be impossible to fix.

IBFS, getting a printer to output a color that you see on a monitor is extremely difficult. This is typically done by using something like a Pantone system that Don mentions. When designing something to print out, you won't necessarily see an accurate color on a calibrated screen. You will however be able to see what the screen color is supposed to represent with the physical Pantone card. If you then print it on a paper type different than the Pantone, then it still won't turn out right. Color management throughout the entire process to display or printing is complicated. Scanning a stamp and comparing it to another scan is simple.

I sure as heck doneed to understand. How do I know this sRGB, if it is different than what I currently get out of my scanner, will work in what I want to use it in?

I currently get jpeg files out of my scanner - is that different than sRGB or are there different types of jpeg files?

sRGB is a colourspace profile that defines how the digital values in your files e.g. jpegs are displayed. Most programs will default to sRGB if no profile is defined.

There may have been some confusion from an earlier post that implied it was a type of file.
As mentioned above, the profile is really only relevant for output devices such as printers and monitors.
