Sub-Surface Laser Engraving.
The simple 2D laser
crystal etching
answer: We take a digital image or scan of a traditional photo (like the
image of Shawnae Jebbia, Miss USA 1998) and etch them into optically perfect
laser crystal without damaging the surface. We only offer the finest quality
crystal which is sometimes referred to as K-9 crystal.
The simple 3D laser
crystal etching
answer: Using a 3D Scanner, we take a 3D image facial scan of the
subject. The resulting 3D facial scan (head or bust) is etched using the same
laser crystal etching system. We also have 1,250+ 3D images in our Image Library which
can be combined with 2D images and 3D heads and text.
We can also convert traditional portrait photographs
into 3D heads.
The simple 3D etching
answer for text and custom 3D images. Our 3D artists can turn any 2D image format
(jpg, adobe Illustrator, bitmap, eps, PhotoShop) into a 3D laser image for
sub-surface laser etching. We can also turn any text font into 3D. Our 3D artists have
created thousands of 3D images from photos. (Our crystal pricing does not
include art work necessary to turn photographs into 3D images.)
The technical answer:
Light is actually an electro-magnetic wave and thus has an electric field. A
laser beam, also known as coherent light creates an electric field greater than
10 million volts per centimeter. The focus of the laser beam creates “free” or
unattached electrons. The “free” electrons, accelerated by the electric field
created by the laser beam causes the high energy electrons to collide with atoms
and ions in the focus area. As the process continues it causes a chain reaction
and produces about 1 million trillion free electrons per cubic centimeter in
about 1 trillionth of a second. This phenomenon is
called “multiphoton absorption.”
Multi-photon absorption
is used to create this crystal art. The process involves focusing a “light fantastic laser beam” to a spot (about one-tenth of the
diameter of a human hair) within a block of optically perfect crystal. The
laser then emits a short pulse beam (a few billionths per second) and produces a
tiny micro crack. The systems then perfectly align and position tens of
thousands of additional micro cracks to create 2D or 3D images.
Although, the laser generates power densities of 10 billion watts per square
centimeter, the surface of the crystal is NOT damaged due to the highly
transparent nature of optically perfect crystal. The resulting images appear to
float within the crystal.
Isn't science great?
Laser engraved images include:
pictures of people, pets, cars, boats, planes, buildings, national monuments,
birds, animals, reptiles, comic characters as well as
text. All we need is a digital picture and within minutes
a
finished product can be provide to you. We have delivered thousands of custom pieces with a single picture
or multiple pictures within the crystal. Let us offer you a 2D,
2 1/2D or 3D image with a
special caption.

What
is Dye-sublimation? Dye-Sublimation or Sublimation for short
is the process of ink changing into a gas or vapor, without first passing
through the intermediary liquid state. An example of this process which most
recognize is "dry ice." In the printing world, the term sublimation is used to
describe heat-activated inks that change into a gas when heated and have the
ability to bond with ceramic, polyester, acrylic and other surfaces.
How Sublimation works? Using an inkjet printer and special dye-sublimation inks
the desired image is printed to special sublimation transfer paper. The
transfer paper is then placed on the sublimation-ready product using various
pressure devices. The sublimation product with the attached transfer paper is
then placed in an oven or on a heat press. The heating process activates the
ink in the transfer paper and changes the ink into a gas. At the same time, the
heat causes a molecular change (greater porosity) in the surface of the
sublimation product. The sublimation product then absorbs the gas resulting in
a transfer of the image on the transfer paper to the sublimation product. A
pressure of approximately 40lbs. per square inch is needed to insure that the
gaseous vapor is forced inside the surface of the sublimation product. When the
sublimation product is removed from heat its polymer surface cools and regains
its original qualities with the ink gases trapped within the surface of the
product. Much like a tattoo, the image is below the surface, protected from the
elements that could cause a decal to scratch, fade or peel.
Benefits of Sublimation? Any digital image (including photographs) can be
printed and be ready to sublimate in a matter of minutes as opposed to silk
screening which requires a setup process to create the screen. The sublimation
process is perfect for projects numbering from one to thousands of custom
pieces. Although, the cost benefits of sublimation are probably better suited
for smaller quantity (1-100) custom projects, the resulting product is superior
to silk screening. The full color benefits of sublimation and the finish offer
spectacular results. Due to ink impregnating the sublimation product polymer
surface there is much greater durability than silk screening. Sublimated images
are extremely washable, scratch resistant and dishwasher safe because the image
is protected within the surface. Sublimation can be applied to floor tiles and
withstand daily foot traffic.
What can be sublimated? There are hundreds of blanks that can be sublimated. We
inventory many blanks, but have access to a wide variety of other sublimation
products. Please see our Photo-Gift pricing for our current products, if
you do not see what you want on our price list, please call us for other
sublimation options.
What
is a Giclee (zhee-CLAY)? A Giclee is a high-resolution
printing process on a special large format printer. Giclees are produced from
digital scans or photographs. Giclees can be printed on a number of media types,
from canvas, watercolor paper, vinyl, metals to transparent acetates. Giclees
are superior to lithography, the colors are brighter and last longer. Giclee
width is limited to the print width of our printers (up to 42"), but the length
of the print can be almost 60".
Giclees use inkjet technology, but are far more sophisticated than your desktop
printer. The process employs at least six colors compared to only 3 colors in
most consumer inkjet printers. The inks are very specialized and some are
quartanted to last up to 70 years.
Giclees are often confused with oil paintings from a distance and are perfect
for office art or promotions. Giclees can be produced economically in limited
quantities. Giclees can stretched and mounted on wood stretcher bars and hung
like original art or framed.
