AS-4000 User’s Guide Basic Operations C Click (Print) on the job toolbar. RIP the job before printing. Setting the Registration Mark Sensor Amplifier Threshold Value If the light intensity (red) for the substrate's base color area is less than 4000, the registration mark on the color measurement chart cannot be read correctly. In this situation, you need to change the threshold value for the substrate's base color area and for the registration mark area. After replacing the substrate, check the light intensity for the substrate's base color area, and change the threshold as necessary when performing the following operations.
❏ When creating an ICC profile ❏ When creating calibration data ❏ When performing color matching for spot colors ❏ When checking spot color accuracy for a job ❏ When checking the color accuracy of the press Note that if the substrate is not white, white printing needs to be performed. Set White Printing to Surface White in Print Info. for the preset on the press. If the substrate is white, check the amount of light intensity. Start the procedure from step 1. If the substrate is not white, print a color measurement chart of the ICC profile to be used, and then check the light intensity. Start the procedure from step 2. A 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. 46
