WHAT IS POLYFOIL?
The short version is: Polyfoil is a technique to foil imprint upon coated sheets using polymer, foil, pressure, and UV curing. The result is a raised foil imprint that is applied without a die.
How it works: Each sheet requires printed dots for the machine to read the registration. Poly is laid down on the area to be foiled, heat activates the poly, the roll of foil applies with pressure over the sheet, then pulls up leaving foil only on the imprint areas. Then the machine ultraviolet cures the sheet.
BENEFITS OF POLYFOIL
1) Raised without Embossing. Because the foil is applied over the polymer, it is raised off the sheet without the cost of an emboss die, or the impression on the other side of the sheet. This is particularly appealing to those designs that incorporate two-sided print, allowing for a raised effect on the cover without affecting the inside copy. Also, at certain quantities, it is less expensive than the combo cost of running through a press twice or a special die to create a foil emboss the image.
2) Low Quantity and Variable Data Options. This foil is actually a digital
