leading edge of the wide bars should also
darken until they are solid all the way across.
7. Vary the MEDIA_ADJUST value in large
increments (about 500) and print the test label
until the printed bar code approaches the
appearance described in step 6. Change
MEDIA_ADJUST
in smaller increments as you
begin to see improvement in the print results.
After achieving satisfactory visual results, you may
want to scan the bar codes with a bar code verifier. No
further adjustment is required if the bar codes scan
satisfactorily. The experimentally derived value will
work with all media that has the same temperature
response. You may send the new MEDIA_ADJUST
value to the printer with VARIABLE WRITE as shown
in the example below, or simply note the value for
future reference.
NOTE: This method should provide optimum rotated bar
code reliability, but may not produce visually pleasing
labels. Labels that "look good" are often too dark for good
bar code performance. You may want to increase the print
darkness for attractive text and graphics.
Do not change
MEDIA_ADJUST
if you adjust the print
darkness. The optimum value for
MEDIA_ADJUST
is
independent of print darkness, and depends solely on the
media sensitivity.
