Note - You need to be especially careful when laser engraving leaded crystal. The
lead in the crystal expands at a different rate than the crystal does and this can
cause cracking and breakage of the crystal. Using a lower power setting can help
this problem, but we always recommend having a spare in case of breakage.
Combining Laser Engraving with Sandblasting
Combining the best of both processes, you can use your laser to engrave the artwork
then use sandblasting to provide a deep etch into glass. Using the laser to create the
artwork mask is an ideal process for one-of-a-kind custom pieces as well as large
production runs. This eliminates the photo process usually associated with sandblast
mask.
¾ Apply an adhesive backed mask material to the glass that you are going to engrave.
¾ Laser completely through the mask and into the glass.
¾ Remove the glass from the engraver and sandblast to the desired depth.
¾ You now have a sandblasted glass presentation with the detail of laser engraving!
Notary Seals - Delrin
Notary Seals Engraving Techniques
Notary seals can be easily manufactured using 1/16-inch thick delrin plastic. A seal
consists of two pieces - a male die and a female die, both shown below. The male die
consists of white lettering on a black background and the female die is an inverted
and mirrored image of the male. Inverting and mirroring are easily accomplished in
most graphics software packages. Simply duplicate the male die, then invert the
black and white colors and then mirror the image.
The male image should be produced without the use of outlines around the text or
graphics. Add a .007 to .010 inch outline to the text and graphics of the female die.
This outline creates a large enough void between the male and female dies to emboss
paper without tearing.
