Dies | Planning Tips
Often used in combination with foil stamping, embossing is
a process that applies pressure to the backside of a material to alter the
surface, giving it a three dimensional or raised effect. The procedure involves
the use of two dies, one fitting into the other so that the raised die forces
the stock into the recessed die to create the embossed impression. A die maker
engraves the desired image, or copy, into several metal plates, which are the
embossing dies for use on an embossing press. Generally, embossing is the process most
often employed to attract attention or convey a high quality textural contrast
in relation to the surrounding area of the stock. A thorough understanding of the process
will allow for a more successful result. An embossed image is shown below.
Debossing is the term used to describe the opposite process
or effect, which involves applying pressure to the front side of a stock forcing
the material away or down from the paper surface. Although it is not as commonly
used as embossing, debossing is occasionally used to provide a different effect or appearance
that fits a particular theme. A debossed image is shown below.
Types of Embossing
Blind Emboss - Blind embossing does not include the use of ink or
foil to highlight the embossed area. The change in the dimensional appearance
of the material is the only noticeable difference resulting from the embossing.
The blind embossing process provides a clean and distinctive or subtle image
on paper stock. It is best used to create a subtle impression or low level
of attention to the piece, yet provide some slight form of differentiation
for the finished work. A sample of a blind emboss using a single level die,
is shown below.
Note: If a multi-level
or sculptured die is used, there will be varying depths to the embossing,
giving the image a distinctive 3-D effect.
Registered Emboss - Registered embossing is a process that places the
embossed image in alignment with another element created with ink, foil, punching,
or with a second embossed image. In the illustration below, the blind emboss
is aligned within the larger printed circle to produce a registered emboss.
Single Level Emboss
Multi-Level or Sculptured Emboss
Combination Emboss - Combination embossing is the process of embossing
and foil stamping the same image. It involves imprinting and aligning foil
over an embossed image to create a foil emboss. A sculptured die, generally
made of brass is used for this procedure. The process requires close registration
that must be controlled to keep the image and foil matched precisely. A combination
die is used to foil stamp and emboss in one operation. The combination die
has a cutting edge around the outside of the die to cleanly break the excess
foil away from the embossed area.
Pastelling - Pastelling is also referred to as tint leaf embossing.
It involves the process of using a combination die to provide a subtle antique
appearance to a substrate that is foil stamped and embossed. Pearl finishes, clear
gloss, or similar pastel foil finishes can be selected giving a soft two-color
antique look (without scorching) to the embossed image. Lighter colored stocks
work best to provide this soft contrasting effect.
Glazing - Glazing refers to a finished embossed area
that has a shiny or polished appearance. Most often this process involves heat
that is applied with pressure in order to create a shined and burned impression
into the stock. Generally, darker colored heavier weight stocks work best
to create this polished effect and to eliminate or soften any burned appearance
that may result from the heat. When used with foil, the process creates a slightly
brighter appearance to the foil.
Scorching - Scorching is similar to glazing except that it is not used
to polish the stock. Instead, scorching does what it implies: as the temperature
of the die heating plate is increased beyond the normal temperature range, a
scorched effect is created in the embossed image resulting in an antique or shaded
appearance to the stock. A lighter colored stock is best for this procedure
to provide a unique two-toned appearance. Caution should be used in requesting
this effect, since it is easy to burn the stock if too much heat is used.
If scorching occurs too close to the printed copy, it can interfere with the
clarity of the printed copy, unless the objective is to accomplish that effect.
Appearance and Shapes
Embossing is basically used to create an effect. The greatest
concern and emphasis on the client's behalf should be placed on the outcome
of the embossed effect. In order to achieve the most distinctive
effect, it's important to understand the embossing process and the types of
dies that are used for embossing.
The three factors that need to be controlled during the embossing
- Pressure - The intensity of the impact on the weight of the stock being
- Heat - The ability to keep the heat consistent and at a proper level for
the best impression.
- Die Depth - The client's artwork or the engraver's efforts will initially
determine this, however, if by looking at the artwork it appears necessary,
the die may need to be tooled to gain greater depth.
Types of Dies
The illustrations show the
side views of the embossing dies.
- The die is straight and level with only one depth.
- It is generally used for lines, borders, and single-dimension
images or line art.
- It provides a well-defined edge for the image.
- It is also referred to as a dimensional die.
- Several distinct levels of depth are used to add a variance
in dimension to the image.
- It is often used with images having unique detail such as landscapes
- A round edge die provides a soft edge effect rather than a hard
- It is often used to provide the sense of a round object coming
outward from the paper and continuing out beyond the stock.
- An alternative that provides the appearance of combining the softness
of a round edge with the well defined lines of a distinct edge.
- It is very effective when used in heavier gauge stocks that may
tear easily upon impact.
- A hand-tooled brass die that has a variety of depths.
- Varying levels of the sculptured die create a dimensional depth
and appearance for the embossed image.
- It is very effective for blind embossing and scorching.
Guide for Die Bevel and Impression Depth
Each die can have a different beveled edge that will affect the appearance
of the embossing. The beveled edge of the die is generally sloped at 30, 45,
50, or 60 degrees. A 30-degree slope will provide only a slight shadow to
the embossed edge while a 60-degree slope may provide a very rounded and heavy
appearing embossed edge around the image that is embossed.
The depth of the die can also be important in creating the desired effect.
The deeper the die, the more pronounced the embossed image. Combining a deeper
die with a higher degree of slope will result in an embossed appearance that
becomes fuzzy and enlarged on heavier grade stock. It is important to recognize
what will work best for the stock and the die that will be used for a project.
As an example, a heavier material, such as cover stock, works well with a beveled
die since the thickness of the stock can withstand the impression of the angled
edges. However, lighter weight stocks will not provide enough thickness to show a noticeable difference when using dies that are angled. Dies with a sharply
angled edge can have a tendency to tear the stock when it is embossed. Generally,
a combination of 30 or 45 degrees of slope with a depth of .010 to .015 results
in the best impression for a sharp and clean embossed image. It is a good
idea to consult with the company doing the embossing if a desired effect is
The guide at the right illustrates the results of embossing with four different degrees
of bevels and four different die depths. The effects shown have attempted
to represent embossing on a 65# cover stock. It is intended to depict
that a die having a depth of .025 with a 60-degree bevel will distort
the image the most, providing an enlarged and rounded or filled-in
embossed image. In comparison, the die having a .010 depth and a 30-degree bevel will have a fine-lined effect around the outside edge
of the embossed image, rather than a heavier, bolder outline as illustrated
with the 60-degree bevel.
- Factors to consider in stock selection include surface characteristics,
grain, gauge, weight, material density, printing inks or coatings to be
applied, and finishing processes to be used.
- Generally, the stocks most receptive to embossing dies are stocks that
are uncoated, heavier in weight, and have a felt finish.
- Embossing on heavier stocks will most often provide greater dimensional
depth and detail.
- If some of the stock being embossed or hot stamped is thicker in gauge,
advise the engraver to "tool" increased depth into the die to
give more definition when it is embossed. The greater depth will compensate
for thickness, memory, and stock resistance.
- It is desirable to have the die "bottom out" or
strike the paper at the point where the stretch of the material comes close
to reaching it's maximum limit without cracking or tearing.
- Coated, varnished, or lightweight stocks have a tendency to crack
when embossed. Paper and ink have limitations in the degree that they can be stretched before cracking. Coatings cannot be stretched, so care should be taken with any type
of embossing on coated or varnished stock.
- Embossing with foil instead of ink can assist to eliminate cracking on
- If heat is applied to the embossed die, such as in foil stamping or glazing,
it will increase the chances of the coated and lightweight stock becoming brittle, which may cause the embossing process to crack the stock after the
die strikes the material.
- Textured stocks may compete with the embossed image if the texture is
too deep. However, for a blind emboss, a slightly textured stock provides the best results.
- Consider the direction of the paper grain when embossing or scoring. Emboss
and score in the direction of the grain since going against the grain can cause cracking
problems. Occasionally, such as with borders, it is necessary to go against
the grain to achieve the desired effect.
- Recycled paper may cause the embossing to be inconsistent in appearance
from sheet to sheet, since the higher the content of recycled fibers, the
weaker the stock when exposed to heat and pressure. Use paper with 30% post-consumer
fiber or less.
- Long-fiber sheets are the best for embossing, since they are capable of handling a wider
variety of embossing dies, particularly the deeper dies.
- Sulfate and foils are the best board stocks to be used when embossing packaging
- Set copy or create images with fonts above 12 point and lines thicker
than 2 point. Use images that are more open and have fewer thin lines. Embossing
will have a tendency to fill in small, enclosed areas, thin lines, or closely
- Thin serifs do not emboss well unless they are large and well defined.
- It is generally best to prepare images slightly larger than the size desired. This is to compensate for the resulting dimensional effect that occurs because the paper
thickness tends to change the size of the image.
- For greater depth, provide more letter space in the artwork.
- Copy or images with very close registration may involve extra work and greater
cost. Be careful not to use trapping techniques on any artwork
appearing adjacent to embossing and foil stamping.
- Screened copy and images with changes in tones do not reproduce effectively
into dies for embossing, so line art should be created as if it were a solid
image or solid color.
- If a beveled die is to be used, the artwork and copy for the
image may need to be slightly enlarged to compensate for the image and copy
reduction that occurs due to the beveled edges.
- Keep images at least 1/2" away from the edge of the stock being embossed
in order to eliminate wrinkles that will occur if the embossed image is too
close to the edge of the stock.
Image and Die Preparation
- If film negatives are to be made for the dies, they must be prepared emulsion
- If the image has no appearance that easily indicates the direction of
the image, mark the film "read right" to show which side prints up.
Identify the top or bottom of the image so the engraver will understand
how the die must be prepared for proper embossing placement.
- Color key proofs, used for viewing the proper image direction, are of much assistance to the engraver when creating dies.
- If the embossed image is to register with a printed image, make sure the
engraver has one of the primary negatives for guidance.
- Make sure the film image is not distorted or altered in size from the
- If stock is to be embossed and also foil stamped, prepare a separate piece
of film or separate digital artwork for each image.
- For multi-level dies (also referred to as sculptured or dimensional dies),
an engraver must be provided with a color coded, solid, opaque film for each
layer to be embossed. The opaque film identifies the silhouette area of
each layer. The engraver must also receive film of the line art that will
contain the images to be embossed. Include a set of color keys that will
be in register with the film and visually show the intended image.
- As a general practice, make sure the engraver has a color key, a mock-up of the design, and any other samples illustrating and defining the
edges, shapes, and levels of the embossed image in order to assist with
identifying exactly how the image is to appear when embossed.

Die Selection Suggestions
- Refrain from using bevel edge dies when embossing and foil stamping as
a combination emboss. The foil will not adhere to the beveled edge.
- Beveled dies are generally made of brass with the edge of the image being sloped
30 to 50 degrees. Do not use magnesium for beveled dies.
- Multi-level sculptured dies work best for scorching and blind embossing.
- Request a proof of the embossing or foil stamping, if possible, to eliminate
surprises from possible misconceptions of the appearance of the finished product.
- Consult a die maker or print supplier before making a final image selection
for the die. The engraver will know that the clarity and sharpness of the details is
one of the most important elements of the foil stamping or embossing.
- Make sure the die maker knows the type of stock on which the die will
- Finer detailed images will be best embossed with a shallow depth. Bold
images are best for deeper embossing. The type of stock and the image will determine
the depth of the embossing die.
General Use of Embossing
- Logos or accents surrounding logos.
- Borders or highlights surrounding images or information used to attract
- Elegant accents for distinctive symbols, images, graphics, or lines.
- Occasionally used for security in the form of seals or symbols of authenticity
on certification for government documents, corporate papers, and official
materials. It is considered an older form of security as more alternatives
in print and technology have been developed.
Note: Before creating an embossed die for use in a project, consult with the organization doing the embossing to insure that the stock and the image desired are compatible.
