AS-4000 User’s Guide Product Overview We therefore use a process known as calibration to adjust color input devices such as scanners, and output devices such as displays and presses, to reproduce colors with stability and accuracy. Each press or device may introduce their own differences, and they may also change over time as they are used. It is therefore important to carry out regular calibration to maintain the color tone set at the time of purchase. Epson Edge Print Label reads the output color chart with a color measurement device, measures the difference between the colors in the data and the color measurement results, and corrects the colors to match.
By using calibration data that stores the correction values along with the ICC profile that was created, you can realize stable color management even when using multiple presses or when the presses are in remote locations. Checking Job Spot Color Accuracy When printing a spot color job, you can check the output color for all of the spot colors used in the job. You can select when to check the spot colors from Before Printing, After Printing, or before and after printing. By performing this check in combination with a test print, you can confirm the accuracy of spot color reproduction before printing.
Also, by using this feature before and after printing, you can check for any color changes that occur before and after printing. 12
