The LAB color model is a three axis color system and LAB colors are absolute, meaning that the color is identical. It’s what’s known as device independent; meaning that the LAB color space is the only way to communicate different colors across different devices. 00:23 It is a three axis system. The first axis, the L-channel or Lightness, goes up and down the 3D color model and it consists of white to black – and all of your gray colors will be exactly...

I can’t stress enough how important it is to calibrate your monitor properly. If a picture is worth a thousand words, now you know what those words are telling you. Watch how to calibrate a monitor using i1Profiler software along with the i1Pro2 spectrophotometer on your Mac OSX. Select the proper white point (color temperature) of your display. Adjust settings for proper luminance (brightness) that will match your prints or press sheets to your screen display. Mount...

I have been asked the question many times before: why does my photography/image look so flat when i convert RGB to CMYK color? Well, the answer is science. RGB is additive color theory. Red, green and blue light when combined produce white light. When red, green and blue light are turned off, there is no color therefore resulting in black. This is how your monitor and television function. CMYK is subtractive color theory. Cyan, magenta and yellow ink act as filters to...

There is no such thing as a universal CMYK. The fact that an image is in CMYK does not mean the color will be correct for a printing press. CMYK is a ‘device dependent’ color space, meaning that the CMYK data will print differently from one CMYK device to another. Every CMYK device has it’s own color profile. Knowing which CMYK color profile to convert to from RGB is very important to the success of color quality. A CMYK printer profile is the...
Read More »This is an interesting and sometimes confusing question. It has to do with different forms of color spaces and how a device renders color information. Device Dependent refers to the CMYK gamut a printer/press can print to – it’s behavior. All printers/presses print differently, therefore they have Device Dependent profiles, or color gamuts. Basically, CMYK values for one device will print differently on another CMYK device. See the difference here between SWOP...
