What To Expect From Blind Embossing


Magnesium or Brass is used to make the embossing dies. Magnesium dies are cheaper but do not convey such fine detail.Brass dies are precision engineered to create the design within the metal. The price of the origination is related to the size of the die. The maximum size of the artwork per die will be determined by the size of the head of the embossing machine (contact your supplier for details).


To confuse everyone, some people refer to this branding as debossing, and the argument ranges between the correct terminology.


Artwork Requirements


The quality of the artwork will impact on the quality of the die and that of the final emboss. High-resolution artwork is required as a vectored eps file. The artwork must be supplied in black & with no gradients.  Anything that is black on the artwork is pushed down by the metal die, anything that is white stays raised.


Most large brands will have a black and white version of their logo within their brand guidelines



Embossing is restricted by the detail and size of the artwork. There needs to be enough space between the lines on the artwork to enable the metal to be etched. As a rule, the text needs to be at least font size 12 aerial, closed fonts may need to be bigger, to prevent filling in.Tiny details such as TM (Trade Mark) symbols often appear as a dot.

Very fine detail such as the complex crests are difficult to accurately etch into the brass die, they need to be simplified to enable the detail to be represented. If you print the logo, at the size required, on a normal office printer, if you can’t see a clear demarcation between black and white then the artwork is unlikely to emboss accurately.

Embossed logos can be infill with coloured matt or metallic foil. This works well on flat items or on the leather prior to assembly. On made up items which have foam or are not flat, the foil can creep up the edges of the shapes or text reducing the precision of the branding.


 

Foil Blocking

Foil blocking uses the same metal die as embossing, but a foil is placed between the material and the die and the neat and pressure adheres the foil to the product without indenting the surface of the material.The foil can be metallic and shiny or matt. Different grades of foil are used on different materials.






The main issues with foil blocking are where you have large areas of foil on grained materials. Here getting 100% foil transfer is not always possible, and small dots or flex of the underlying grain can appear, piece by piece. Foil blocking is, therefore, better suited to logos with less solid fill, and is perfect for text as shown above.
