AS-4000 User’s Guide Safety Instructions and Notes on Usage Notes on Usage Conditions and cautions for correct reproduction of spot colors ❏ Check the color gamut that can be reproduced by SurePress. You can use the Epson Edge Print Label to check if the spot colors you are using fall within the gamut. ❏ The substrate must be white. ❏ Apply the calibration data created by this product to the print job. In the following situations, the spot colors may not be reproduced correctly. Cautions for color measurement If color measurement is interrupted, the results of the measurement are invalid. Note the following points to avoid having to print again.
❏ Do not open the cover of the color measurement unit during color measurement. ❏ Make sure that there is enough substrate remaining in the feeding unit. ❏ Make sure that there are no splices in the substrate for the area where the color measurement chart will be printed. If the color measurement chart is printed on the splices of the substrate, errors may occur during color measurement or affect the color measurement results. ❏ Make sure that there is enough ink remaining. ❏ If you print a color measurement chart with more than 10 frames, periodic head maintenance will start during color measurement. We recommend that you perform head maintenance before printing.
Precautions when handling the paper presser Do not touch the paper presser except when instructed to do so in this guide. If the paper presser is deformed, it may affect the color measurement results. 8 Item Explanation When printing on transparent substrate or foil paper You can reproduce spot colors by performing surface white printing, but the color reproduction accuracy will decline. When the color of the adhesive paper differs from the color of the area to which it will be attached Since the color is matched to the base color of the release paper, the tone may look different when the actual color of the area to which the adhesive paper will be attached is different.
When there are individual differences between lots Color reproduction may also differ due to individual differences in the substrate. In this situation, perform calibration to match the colors. When you have been printing for a long time using the same press and settings Color reproduction may vary due to the way the press changes over the years. In this situation, perform calibration to match the colors.
