I consider LAB color space and it is use to become probably the most important subject if this involves the entire image processing concept.
Why is that, you request? since the LAB color space may be the only “device independent” color space in Illustrator, so when used properly, it’s the just one that will permit the consumer to achieve the best color match from capture to show to print.
To put it simply – the LAB color space is the only person representing how a eye sees color. Which is an essential factor if this involves making certain color match through the process.
Allow me to explain what “device independent” means:
To put it simply, “device independent” color space is a that no matter which system is used a persons eye will invariably begin to see the identical color.
RGB an CMYK color spaces are component based spaces. Whet this means is the fact that whenever a color is “produced” it consists of certain levels of each component. However , different products use different components. Take for instance two monitors. Their RGB phosphors will change, so even though they might display same amounts of RGB components, a persons eye might find two different colors. This is also true for CMYK – take two ink jet printers, and same CMYK amounts can lead to the attention seeing two different colors.
That’s not the situation with LAB. Once the same LAB value is measured on a variety of products (that will most likely require different component, RGB or CMYK, to achieve that, that is what device profile do), a persons eye will invariably see the identical color.
An excellent book to see about Illustrator LAB color is Serta Margulis’s “Illustrator LAB Color: The Canyon Conundrum along with other Adventures within the Most Effective Colorspace”
Which causes it to be probably the most effective color space!
This book is outstanding! It isn’t for novices, which is no easy read for advanced user either – you must have a good knowledge of what you are doing with RGB or CMYK color changes, and fundamental retouching first. Employed in Lab is definitely an incredibly effective method to take out very natural and vibrant colors with a smaller amount effort.
Serta Margulis’s understanding of color runs deep. This book is simply amazing. If color matters for you because it is in my experience, this can be a must read book.
Serta basically advocates color correction and image improvement through LAB, and that he advances compelling evidence to aid the idea. The secret is to buy an understanding of what types of images LAB performs exceptionally well at, where it fails to deliver (by which situation Serta highlights which from the remaining color spaces, RGB or CMYK, is the foremost option). Also, he demonstrates image correction in as couple of steps as you possibly can, frequently without choices (rather, he creates what he needs by using more helpful channels… which will help avoid apparent selection edges that don’t match).
When I stated, it isn’t a simple read. I keep picking up and browse out a couple of pages here or there, testing out techniques when i complement. By now I personally use LAB almost solely for color corrections.
In addition, despite the fact that this isn’t among the free illustrator downloads, it’s very easy to show many of the book techniques into illustrator actions, that we did. Just feel the motions and record them – that’s what is needed.
