We then send the document to the printer via WLAN (wireless LAN) to print. The printer settings we use are as follows: We connect the printer via Wi-Fi to the same wireless network as our test computer. The Parrots picture provides a more realistic representation of the printer's performance when printing a photo. The presence or absence of this zig-zag line in a display or printed image is a tell-tale sign of how wide a printer's color gamut is.

This zig-zag line roughly denotes the most-saturated tint of that particular hue. The characteristic that sets it apart is the presence of a bright zig-zag line across all the colors at various heights. Like HSL charts found in many digital art programs for precise color-picking, the Granger chart is a picture that displays a very wide array of colors, organized by the color's hue from left to right and how light or dark the color is from top to bottom. To evaluate a printer's color gamut, we use the 'Parrots' picture as a sample and the Granger chart (sometimes referred to as the "Granger rainbow").
