circle), so we'll want to adjust the artwork before engraving. To determine how much to adjust your artwork, we'll need
to do a simple calculation that tells us the percentage of stretch or shrinkage we need to perform. You can use either the
diameter or the circumference to make the calculation; just don't mix the two.
Determining whether you use diameter or circumference is a matter of which one is easier to
measure. If you want to measure circumference, use a flexible ruler and wrap it around the
glass. To calculate circumference, measure the diameter and multiply by Pi (3.1416):
Circumference = Diameter x 3.1416.
For objects with a larger middle section:
Shrink the artwork by dividing the drive wheel side diameter by the middle diameter and
multiply by 100 to calculate the percentage of adjustment. For our example the calculation is:
Because our calculation percentage is less than 100, we need to shrink the artwork to 71.5%
of its original size. Adjust the size of your artwork in one axis only.
For objects with a smaller middle section:
Expand the artwork by dividing the drive wheel side diameter by the middle diameter and multiply by 100 to calculate the
percentage of adjustment. For our example the calculation is:
Because our calculation percentage is greater than 100, we need to expand the artwork to 129.6%
of its original size. Adjust the size of your artwork in one axis only.
Other considerations:
In these two examples you'll notice that the "middle" varies depending on where you measure.
Because of this, you'll never be able to get every piece of artwork perfectly sized. Depending on
how much room the artwork takes up, you may want to experiment with the expansion or shrinkage
of your artwork to fit your particular glass shape.
