Changing the Clear Coating Settings

When you execute clear coating, the printer applies chroma optimizer (CO) ink onto the printing surface and allows you to adjust the glossiness.

You can also create the areas to be clear-coated and save the area information as a form. When you use a form to perform clear coating, you can realize decorative effects that cause certain characters and patterns to pop out.
