CTS-1 - Screen Proof Colors

This version of the cropped image shows the colors as they were captured on-screen in Photoshop "Proof" mode for printing.

The CTS-1 frame shows some resolution targets and the six primary screen/print color blocks (RGB and CMY). The upper left target is shown at 100% black, 50% black and 18% neutral gray. The resolution targets show line pairs from 30 pixels to 6 pixels wide when scaled for an 16"x24" print. The color blocks (Red/Green/Blue and Cyan/Magenta/Yellow) were originally set in Photoshop with CMY blocks set to pure CMY colors and the RGB blocks set to their matching CMYK equivalents. Cyan is 100-0-0-0 and it’s complement Red is 0-100-100-0. The colors were created with CMY values and then the full chart was converted to sRGB for printing and film strip images. The gradient bar on the right side of each color target goes from 0 to 100% density. The color overlays in the upper right target are set at 50% density. The bottom portion of each color bar is also set at 50% density.
