What
Makes a Product Laserable?
Lasering involves the use of a highly concentrated light beam to
burn into certain materials. Depending on the type and wattage of
the laser, it is possible to burn into or through a variety of materials
from paper to steel. Laminated plastics, such as Rowmark materials,
can be engraved and/or cut through using low wattage lasers (25
to100 watts), taking into account the power of the laser when adjusting
the settings.
However, the laser beam generates heat. Since plastic is very heat sensitive,
success in lasering plastics depends on the thickness of the cap,
the heat tolerance of the plastic being used, and the control exercised
over the laser settings.
Rowmark products were initially developed for rotary
engraving. When laser technology was perfected, we developed new products
and adapted some standard product lines for lasering. Rowmark materials
are still widely used by rotary engravers, and some of these traditional
materials do not laser well. Other products, however, are regularly
cut and engraved with lasers even though they are not advertised
as laserable because they need special attention to achieve optimum
results (such as lasering with two passes instead of one). Most of
the products Rowmark recommends for lasering have one thing in common
they are made with foil caps (.001" thick).
 |
This thin foil cap allows the product to be engraved easily and
with an extremely high degree of detail, because so little heat
is required to penetrate the cap. Cutting through the .010"
cap of other product lines is possible but usually needs to be done
in more than one pass and even then, depending on the core material,
can cause heat damage to the product.
Some of our core materials are made of modified acrylic, while
other core materials are made from a softer ABS plastic with a lower
heat tolerance. There are certain advantages to using a softer core
material in several product lines, but laserability is not one of
them.
The ideal material for lasering has a .001" cap over an acrylic
core. The following materials qualify in this rapidly expanding
category:
.001" cap over acrylic: LaserMax (includes metallic
finishes); LaserMark Front Engravable (includes wood
and marble finishes) and LaserMark Reverse Engravable; FlexiBrass
and FlexiColor; Granites.
.005" cap over acrylic: Textures
- The thickness of the cap usually requires two passes for effective
engraving, but because this product is co-extruded acrylic and
highly durable, it has proven to be an excellent choice for
lasering.
Single-ply acrylics: Cutting - ADA Alternative
Appliqué
and Substrate; model making material; and Ultra-Mattes clear.
These products are excellent for laser cut-outs. Since there
is no contrasting cap, only rare applications would suggest
a need for raster engraving; but, should the need arise, these
products are easily engravable as well.
Transitional Product Lines
Although Rowmark only recommends the above product lines for lasering,
several products will, with some care and often more than one pass,
accept lasering. Most products with a .001" cap and an ABS
core can be effectively laser cut and engraved, but may burn and/or
melt because of the soft core. In addition, products with a .010"
cap on an acrylic core can also be lasered with care and with more
than one pass.
Because of the heat generated when engraving through the thicker
cap, these products are also prone to heat damage in spite of the
more heat tolerant core. Both categories are listed below.
.001" Cap and ABS Core: NoMark Plus; Standard
Metals; and Mattes with dark cores.
.010" Cap on an Acrylic Core: Outdoor Weatherable
Metals; Lacquers; Slickers; and Ultra-Mattes Front and Reverse
Engravable.
Traditional Products Not Recommended for Lasering
The following products do not laser well. They were originally
designed for rotary engraving and are still excellent products for
that application. Because these products have a softer core and
thicker cap, it is difficult to control overheating and burning.
The Woods and many Mattes have a .001" cap over a white ABS
core, and because the core color is white and ABS, it shows heat
damage more readily than black ABS. Therefore, these are not recommended
for lasering
.010" Cap over ABS Core: Satins
.005" Cap over ABS Core: Silks.
.001" Cap over white ABS Core: Mattes
with a white core.

True
Laserables
LaserMax
Our LaserMax line includes 18 matte finish color
combinations
and six metallic finishes. Introducing a new foil formulation
with exciting color additions, LaserMax offers the greatest ease
in laserability of all our product lines. The .001" foil cap
over an acrylic core makes it the ideal choice for laser engraving
and cutting, but it can be rotary engraved as well. The white/black
and black/white are particularly effective for photo laser engraving.
(See Photo Laser Engraving in the
contents bar.)
LaserMark Front Engravable
Our
LaserMark line includes 16 matte finish color combinations, including
two marble finishes and one wood finish. LaserMark was designed
for lasering but can be rotary engraved as well. The .001"
foil cap over an acrylic core makes it the ideal choice for laser
engraving and cutting. The white/black and black/white LaserMark
are also excellent for photo lasering.
LaserMark Reverse-Engravable
This material is similar to Ultra-Mattes
Reverse-Engravable
or Slickers (see below) except that the cap material is a foil (.001")
over the front-facing, clear acrylic core, making it ideal for laser
engraving and cutting. It is currently available in ten colors and
two metallics with matte finish. We also offer a clear gloss black
and two clear gloss metallics (similar to Slickers). All can be
back filled using any color of paint (See Special
Uses/Reverse Engraving). It is rotary engravable but not
outdoor weatherable.
FlexiBrass and FlexiColors
This thin (.020"), flexible material (.001" cap on acrylic
core) is ideal for laser engraving and cutting. Available in five
metallic, three marble, and five matte color finishes, the
FlexiBrass and FlexiColor can also be successfully rotary engraved. Their strength and
flexibility make them ideal for unusual applications, such as adhering
to rounded surfaces or placing in hard-to-reach industrial applications.
FlexiBrass
and FlexiColor can be ordered with an adhesive backing for ease
in fabricating. The thinness of this product together with the low
power settings possible for cutting allow for highly detailed cut-outs.
LaserLIGHTS
This product is an ultra thin laminate plastic with adhesive backing. The cap of this product is less than .0005" and is laminated to a .004" core, making it by far the thinnest engravable product that we offer. It has the look and feel of a label, but can be personalized through either laser or rotary engraving. It is available in 12 combinations of color and metallic finishes.
LASERmag
This magnetic material is .020" thick and has a cap thickness of less than .0005". It is available in 3 combinations of metallic finish and black. This product can be personalized through laser cutting and engraving in addition to its magnetic properties.
Textures
Textures are available in 20 color
combinations
and are co-extruded with a surface texture to help the materials
resist scratching, dirt, grease, and other foreign substances. Widely
used for industrial applications, Textures are a rugged, durable
acrylic product with a cap thickness of .005". Although they sometimes
require two passes with a laser, Rowmark
recommends this product for laser engraving and cutting. It can
also be rotary engraved and is outdoor weatherable.
Because the thicker cap contains more pigment than other true laserables,
some pigment may cause staining when used with a white core. The
second pass will eliminate this residue particularly if the settings
are well controlled. In some cases it may be necessary to clean
the engraved area with either a medium strength solvent or
a citrus cleaner.
ADA Alternative Applique and Substrate
Rowmarks ADA product line was designed for the production
of architectural signage to comply with the Americans with Disabilities
Act (ADA). It is available in two components. The substrate material (1/16" or 1/8")
and the appliqué material (1/32" available with or without adhesive), is applied in
a contrasting color to provide raised lettering and graphics wherever
required. The matte finish of both products is essential to ADA
signage and can be mixed with our Ultra-Mattes Reverse-Engravable
line as mentioned below. This material can be either lasered or
rotary cut and is available in 22 substrate colors and 21 appliqué
colors.

Transitionals
Standard Metals
The Standard Metals are manufactured with a foil cap. The foil
cap is a true metallic surface that is hard to distinguish from
a solid gold, brass, silver, or aluminum plate. The foil cap is
.001" over an ABS core and is ideal for detailed engraving
using a rotary engraver. This product can be laser engraved, but
care should be taken because of the soft core. Whenever possible,
Rowmark recommends using LaserMax metals instead.
NoMark Plus
NoMark Plus
products are the same as our Standard Metals, but are hard coated with a special formulation
that provides durability without losing the metallic sheen. They
are also manufactured with a foil cap that is scratch- resistant
due to the hard coat application. The foil cap is a true metallic
surface that is hard to distinguish from a solid gold, brass, silver,
or aluminum plate. The foil cap is .001" over an ABS core and
is ideal for detailed engraving using a rotary engraver. This product
can be laser engraved, but care should be taken because of the soft
core. Whenever possible, Rowmark recommends using LaserMax
metals instead.
Outdoor Weatherable Metals
Our Outdoor Weatherable Metals are designed to withstand
outdoor elements
while providing a true metallic color. The .010" acrylic cap
on acrylic core works well with a rotary engraver. Although Rowmark
does not recommend this product for lasering because of its thick
cap, we have found that with some care and using two passes, it
can be successfully lasered.
Mattes
Mattes are available in 30 color combinations, and have a soft
matte finish. Because of the ultra thin (.001") cap on an ABS
core, Mattes allow highly detailed engraving, even on a rotary engraver.
Although we do not recommend lasering Mattes, we have found that,
with some care and two passes, the Mattes with dark cores can be
successfully lasered. The white core Mattes readily show the effects
of heat stress and are not recommended for lasering.
Lacquers
Lacquers are available in
22
color combinations and have a high gloss, glass-like appearance.
The cap is .010" thick on an acrylic core, and this material
is primarily suited to rotary engraving. This product can be lasered
using special care and two passes. Lacquers are recommended for
outdoor use.
Slickers
Slickers are available in 17 colors. Because this is a reverse
engravable product, the engraved artwork can be back-filled with
any color(s) of paint. The high gloss, glass-like surface of the clear
core material is this time positioned to the front of the cap sheet
which forms the back field of color. When this cap is engraved from
the back (with the image in reverse), that same image, viewed from
the front, is right reading and clear where the material is removed.
This clear area can then be backfilled with paint. Slickers can
be lasered if care is taken but will require two passes because
of the .010" cap thickness. The core material is acrylic, and
this product line is outdoor weatherable.
Ultra-Mattes Front-Engravable
Another outdoor weatherable product is Ultra-Matte Front-Engraveables.
These are available in 31 color combinations this time with a soft
matte finish. They have a .010" cap which can be lasered if
done with care and two passes.
Ultra-Mattes Reverse-Engravable
The Ultra-Matte Reverse-Engravable, product line is available in
25 colors and is capable of being reverse engraved and back filled
with color(s). The clear, matte finish surface is part of the core
with the color cap laminated to the back. When this cap is engraved
from the back (with the image in reverse), that same image, viewed
from the front, is right reading and clear where the material is
removed. This clear area can then be back-filled with paint. This
material, because of its matte surface and single color appearance,
is often interchanged with the ADA product line and is fully ADA
compliant. Like the ADA material, it is also available in 1/32"
and 1/16" thicknesses. The .010" cap under acrylic core
makes it possible to laser using care as well as two passes. It
is rotary engravable and outdoor weatherable.

Traditionals
or Non Laserables
Satins
Satins are available in 47 color combinations and have an elegant
brushed satin finish that gives a special quality to any project. The .010" cap is laminated to an ABS core,
and the material is primarily suited to rotary engraving.
Silks
Silks have a soft matte finish and are available in 7 color combinations.
Silks have a .005" cap on an ABS core, which makes them unsuitable
for laser engraving. This product allows for greater detailed rotary
engraving than is possible with Satins or other products whose cap
is .010". This product is primarily suited to rotary engraving.
