Good morning
Is possible to add option to use Black Point Compensation in color convertion and Color Management settings?
I am working to give professional tools about Color to CorelDRAW users.
I teached about color conversion last week and I showed how close CorelDRAW can convert colors when compared with Photoshop.
But, there is one tool that has a huge difference, and it is Black Point Compensation.
This could be addressed to implement?
Thank you
For those who simply need to complete standard acceptable color tasks, again things haven't really changed.
Acceptable color standards have lowered so you may need to adapt, the great color that you print may look awful on the web or for display. Yes, there is a significant difference, display applications such as those for presentation view vastly different than web browsers. Web browsers are really bad.
I suggest that such a file creator buy medium priced displays, more like the average viewer of your work may purchase.
I suggest in CorelDRAW that you use a standard web-based color management setting, customize to use perceptual rendering and save it.
Have fun and make money.
For those who do color critical work things have made very modest improvements. The newer specifications have resulted in a higher degree of repeatability in color. There are also now a very modest proliferation of 16 bit RGB output devices available.
With this said most things have remained the same and that in my opinion is a good thing.
You need to build a light controlled studio environment so you are viewing your display properly. A 2 degree light angle, 5,000 or 6,500 Kelvin light source. Heavy drapes or no windows to control ambient light.
You need to purchase color calibration equipment, for display only an Xrite Spyder Elite will work. More intensive work I use an I ONE system.
You will need a display capable of displaying at least 98% Adobe RGB color space. There is a significant difference between setting up a display for color managed working creating a file for color managed work. Benq make nice 20" displays for about $900 U.S., ViewSonic has 27" units for a bit over $1,000 U.S., there are others where the sky's the limit. $40,000 video models.
A display requires a custom ICC profile it should be as wide a gamut as possible. My ViewSonic exceeds Adobe RGB.
A graphic application RGB color profile should NEVER be set to a display specific ICC profile but BE SET to an industry standard ICC profile. For web, sRGB (all over the world), for press RGB regional settings apply, Adobe RGB, ECI, Japan, are samples check within you region.
CMYK profiles are regional by media, for creation applications NOT SPECIFIC media but industry standard general medial types. Such as coated, web coated, uncoated and web uncoated or newsprint.
Calibrating you display for the widespread gamut possible, setting the creation applications to industry standards both RGB and CMYK and working in a controlled well-lit environment allows the most repeatable color in a global working environment.
This allows you to create in controlled conditions, providing files for output that are created within parameters that the output devices are designed to work within. This allows the final output conversions to be repeatable and pleasing.
As far as application color management Adobe has continued to do as they please their users are stuck with their color engine and mind set. They only provide compatibility with Adobe products. Relative Colorimetric with Black Point Compensation turned on is not Relative Colorimetric rendering, (in fact it's much closer to Perceptual Rendering) and unfortunately is the Adobe default.
Black Point Compensation is not supported by all applications and when it is supported it may or may not be supported identically in all the applications.
CorelDRAW has poor defaults, it sets Relative Colorimetric as a default rendering. In fact, a 2007 ICC white paper states that Relative Colorimetric Rendering without Black Point Compensation has little to no value and I agree.
As file creators and designers, we must understand that those who view the end result of our work DO NOT measure color they PERCEIVE color. The Perceptual Rendering intent perceives color like we perceive color. That point is what makes Perceptual Rendering a valuable tool.
Changing that to Perceptual Rendering is ICC Compliant, is much closer to the Adobe default and is supported everywhere by everyone so universally you have better control over your output.
CorelDRAW supports multiple color engines. If getting as close to Adobe conversions as possible is what you want, I suggest using LCMS as your color engine.
I use WCS because in a Windows system all RGB for the display must be handled by WCS, it's built into Windows. For me it reduces the number of conversions and a 1- or 2-point difference is invisible.
The reality of the evolution of color management for the file creator for the last 5 years is that very little has changed. I only see that very high-end inkjet work has progressed in a manner useful for designers.
