AS-4000 User’s Guide Basic Operations Creating Calibration Data The calibration data is a file specific to the press. This file is saved in the press. It is not saved to the print settings shared folder. Note: What is calibration? Even if you specify the same color, it may be printed using a completely different tint depending on the display device or press you are using. 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. Furthermore, 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. A For white substrates, check the light intensity (red) of the substrate’s base color area.
If the light intensity on the amplifier display is less than 4000, go to step 2 as the threshold value needs to be changed. If the light intensity is 4000, you do not need to change the threshold value. Go to step 3. B If the substrate is not white, or if the light intensity of the amplifier is less than 4000, print one frame of the color measurement chart for the ICC profile to be used, and then change the amplifier threshold. See the following for more details. U “Setting the Registration Mark Sensor Amplifier Threshold Value” on page 46 Once the amplifier threshold has been set, go to step 3. 41
