HOW FOIL FINISHES ARE MADE
The special finish is carried out by applying a transparent polymer, which serves as a base, to the areas marked in your file with the "Finishing" colour swatch. If you selected gold or silver foil to enhance your graphic project, a gold or silver film with the selected finish is then applied on top of the this transparent polymer. The transparent polymer always acts as a base, which means the foil finish has a slight raised effect.
WHY IT IS IMPORTANT TO REMOVE GRAPHIC ELEMENTS UNDER GOLD AND SILVER FOIL FINISHES
Gold and silver foil s finishes are completely opaque a printed colour is present underneath and a slight misalignment occurs during the foil application, that colour may become visible, creating an unpleasant duplicated effect.
Therefore, we strongly recommend that you always remove any duplicated elements placed beneath the foiled artwork, leaving only the background colour.
In this example, which is incorrect, if I turn off (hide) the Finishing layer, I can see that there is graphic and text beneath the foil finish: these will be printed, creating an unpleasant "shadow" effect:

Here are some additional tips to make the most of these foil finishes:
You will achieve better results by applying the foil finish to small areas rather than very large surfaces
The thickness of foiled lines must be at least 1 pt
The minimum font size of foiled text must be at least 10 pt
Foiled elements must always maintain a safety margin of at least 3 mm from the cut or fold (please refer to the instructions for the product you have chosen for more information)
To make the most of gold and silver foil finishes, remove any duplicated graphics from the CMYK print layer —leaving only the background colour— to achieve a clean and professional result.
