Week #8: 3/21/11 Digital Color Mgt.

"Sitting over a hot computer ain't my idea of fun. My creativity goes almost completely into picture taking. (But) I suppose if I ever retired, I would enjoy learning the Photoshop craft far more than playing golf." - Herbert Keppler - On going digital. (Popular Photography & Imaging, January 2005)

Now that we understand the digital RGB #s, let's use that knowledge!  Below is a handout detailing how to use a Curves Adjustment Layer to properly adjust for color and tone in our digital images.

Today we'll be talking about proper color management workflows and how to take an image from monitor to print with as much color accuracy as possible.

Colors on a monitor are displayed using a combination of RGB light, while printed colors are typically created using a combination of 4 inks CMYK.  Because the RGB and CMYK color models use different methods to display colors, each produces a different gamut, or range of colors. 

The color space for a device is defined by the gamut it can produce. And an ICC profile is a description of a device’s color space.  The profiles are used to help ICC systems communicate properly and translate your color gamut from device to device accurately.



Understanding the Color Management Workflow

Color Management Workflow:
STEP 1:  Calibrate your monitor
STEP 2:  Set up the Photoshop Color Management Environment
STEP 3:  Assign a Profile to the image
STEP 4:  Soft Proof your image on screen
STEP 5:  Print your Color-Managed image using ICC Printer Profiles

Below is a handout detailing the proper color management workflow steps for printing to an Epson inkjet printer.
