To calculate this, we measure the difference between 24 different colors and the printed version of each corresponding one.įirst, we open the ColorChecker chart in Adobe Acrobat Reader and verify that all settings are standard before printing the document. The color dE (or ΔE) is a metric that shows the difference between two colors. The updated ColorChecker chart provides a more varied palette of six gray shades, six primary/secondary colors, six miscellaneous colors, and six natural colors, letting us better determine how accurately a printer can reproduce a greater variety of color sets used in different print types. Alternatively, some printers that scored relatively poorly according to our previous criteria might still be able to produce accurate-looking images. However, they might be viable for printing logos and digital designs as intended. These generally didn't reflect real-world colors that could be captured using a camera, so even though some printers might print brighter colors accurately, they may not render natural scenes properly. Note: Our previous methodology (v0.8.1) resulted in relatively high dE scores for many printers because we used very vibrant Pantone colors. A lower variation scores better because the difference between the two colors isn't very significant. We then scan each color with a calibrated NIX QC Color Control Sensor, which gives us a value we use to calculate the color variation. We use the same paper and print settings for each printer we test to ensure that the results are comparable. If this isn't possible, we use AmazonBasics Multipurpose Copy Printer Paper at 92 GE brightness for portable printers, we use the dedicated paper type for the model. We print the color chart in PDF format, using Adobe Acrobat Reader, on a 4" x 6" sheet of glossy photo paper recommended by the printer manufacturer. We use the Macbeth ColorChecker Color Rendition Chart, which has 24 individual colors, to test how well a printer can reproduce various types of colors used in different print types. We use our color accuracy test to measure how accurately a printer can reproduce colors. ![]()
