How is the 'double-sided foil stamping' mentioned in the description different from commonly used foil printing?
I saw the unfamiliar processing term 'double-sided foil stamping' in the product description. I am asking because I want to know how it differs from ordinary printing where foil is stamped on only one side.
Unlike the standard method of stamping foil on only one side, foil is delicately applied to both the front and back sides so that a metallic luster is revealed whichever side you look at.
Foil stamping refers to a method of pressing thin metallic foil onto paper using heat and pressure to engrave shiny lines or lettering. Conventional foil printing is often done on only one side of the paper. This is because applying strong pressure easily leaves impressions showing through to the opposite side of the paper, making it difficult to cleanly stamp both sides. Double-sided foil stamping is a technique that delicately controls this pressing effect to apply a uniform metallic luster to both the front and back sides.
syubisya PRINTING lab's fu-butu Paper (fu-butu紙) has this double-sided foil stamping applied onto the surface of paper that has completed vivid full-color printing [1]. By threading strings through the holes punched at the top and bottom and interweaving them, it can be assembled into a mobile suspended in the air [2]. It turns in the wind. As the paper hanging in the air rotates, no matter which way it turns, the metallic lines engraved on both sides capture light evenly.
hmmm, considering the use of a mobile where both sides are exposed in the air—unlike a flat card touching a wall where only one side is exposed—the delicate finish of pressing foil onto both sides connects to a design intended to catch the light from every angle of view.
The specific luster types or color specifications of the foil used in the double-sided foil stamping have not yet been confirmed.
