These are the original source documents that were used to produce the paper charts for CTS-1 thru CTS-4. The first 3 were produced with Adobe Photoshop as direct vector object targets, allowing precise selection of shapes and colors. CTS-2 and 4 were made in 8-bit RGB mode using the sRGB color space. CTS-1 and 3 were made in 8-bit CMYK Color Mode and then converted to RGB mode for printing. Each image is sized to print on 8.5""x11" paper with the internal boxes sized at a 2x3 aspect ratio for capture by cameras. If desired, you may print these charts directly on your own printer for your own use to capture the images on film using your own camera and setup.

CTS-1 RGB CMY Targets

This version shows the chart as formatted for printing on 8.5x11" glossy print paper. This was used for the DSLR print scans and the film captures.

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 5 pixels to 2 pixels wide when scaled for an 8x10" 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 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.
