I've been trying to improve my scanning skills lately. I discovered that scanning as Lab color was giving me the best results, at least as far as I could see. But, I had some worries about how it would show up on different browsers. Fortunately for me, I got some great information from fellow illustrator, Mary Peterson. This is what she posted to our online illustrator's group:
"My husband owned a color separation house for years.
In a commercial environment, images are first scanned in LAB. As Marion learned, this is the largest color space available, very close to what our eye can see. My husband archived his client's work in the LAB color space and considered it the "original". From this "original" he converted to RGB, sRGB, CMYK or grayscale, depending on the need.
Adobe RGB is the next largest color space and the appropriate scanning mode if you don't have LAB option.
sRGB is best for web (its a much smaller color space than Adobe RGB and intended for reproducing web safe color)
CYMK and grayscale for offset printing."
Thank you, thank you, thank you, Mary! In case you missed it, have a look at Mary's fabulous illustration here!
And, to see what this is all about, have a look at my experiments below.
