2015 FIAC Bookmark

雕刻版燙金 / Micro Embossing

樣本由法國設計工作室Akatre為2015年FIAC(世界第五大當代藝術展覽-巴黎)目錄設計的書籤。採用h+m製造的模具和Kurz生產的熱燙錫,在Curious Matter 270g雙面紙上完成雕刻版燙金。

The sample is a bookmark designed by French design studio Akatre for the (world’s 5th largest Contemporary Art exhibition in paris) catalogue for 2015. The Curious Matter 270g duplex has been micro-embossing using dies from h+m and foils from Kurz.

 

建議事項
微結構、微凹凸、微蝕刻熱燙箔壓印等,均指一種在不需要配對物件的情況將某種細緻的文理雕刻到模具上的熱燙箔壓印技術。

  • 一旦應用於金屬燙印箔上,其紋理會通過光的反射產生出視覺效果,看起來如不同角度的精緻線條構成。
  • 微凹凸壓印應用於金屬箔上,而非用於霧面或緞面箔上,圖案的反光效果將更加強烈立體。
  • 為了確保箔紙在紙張上位置正確,事先多做幾次嘗試,如果壓力設置不正確,箔紙可能會出現一些微小縫隙,造成不好的斑點效果,在深色紙張上尤其明顯。

注意事項
因為為凹凸壓印所涉及的都是非常細小的細節,因此是一個需要更多注意力的精細過程。

  • 由於微凹凸壓印的特點是細節非常精確,比起鎂板更宜採用較堅固的銅板模具。
  • 不要選用低於135g的紙張。
  • 由於微凹凸壓印模具是由CNC(數位車床)上製作的,所以在某些圖案尚需花費近50個小時才可雕刻完成。
  • 如果要將微凹凸壓印模具和特殊箔紙結合使用,請勿先採用箔紙後再進行壓印,因在紙張上進行壓印時所施加的壓力可能會造成箔紙上的紋理損壞,解決辦法是在同一模具上將微壓印和壓花圖案結合。
  • 切勿設計雙面微凹凸壓印,在另一面進行熱燙箔壓印時非常有可能損壞第一面的壓印效果。

 

DOs
Micro-structure,micro-embossing,micro-etched hot foil stamping…all designate a type of hot foil stamping in which a very fine texture is engraved into the die, without requiring a counter-part.Once applied to a metallised hot sampling foil, the texture, which is usually made of microscopic lines at different angles, creates visual effects through the diffraction of light.

  • DO privilege smoother papers.Micro embossing does not use counter dies, and the textured effect is very thin down to 0.03mm.In order for the effect to be visible, the paper should therefore be quite smooth.
  • DO associate micro-embossing with metallic foils rather than matt or satin foils.The reflective effect of the micropattern will be all the more dazzling and 3D like.
  • DO consider using standard micro patterns within your design.Die manufacturers like h+m can integrate one of their standard micropatterns to the shape of your choice, including typography if the letters are bold enough for the pattern to show.
  • DO proceed with some tests to ensure the foil sets properly on the paper.Some tiny gaps could appear in the foil if pressure is not set correctly, which can create an unpleasant speckled effect, especially visible with darker papers.
  • DO think of combining on the same die micro-embossing motives with embossing designs.

DON’Ts
Because micro embossing is all about very fine details, it is a precise process requiring much attention and care.

  • DON’T go for cheaper, magnesium dies.Since micro embossing is characterized by very precise details, more robust brass dies are more appropriate.
  • DON’T choose papers with a weight lower than 135g.
  • DON’T expect quick lead times.As micro-embossing dies are produced on special CNC engraving machines (computer numerical control machines), some motives can take up to 50 hours to be engraved, depending on the motive and its dimensions.
  • DON’T emboss the paper after applying the micro-structured foil if you choose to combine both techniques.The pressure applied while embossing the paper could damage the texture created on the foil.The solution is to combine both the micro-embossing and the embossing designs on the same die.
  • DON’T limit micro-embossing to greeting cards and brochure covers.In particular,micro-embossing can bring an eye-catching wow factor to luxurious packaging and labels.
  • DON’T design two-sided micro-embossing.Although possible in theory, it is most likely that hot foil stamping the second side will damage the first side.
