7. Scale factor

The data created from each individual tag for the database was carefully investigated,
although they are not frequently checked. There could be a chance for the printable
tags to receive by the time a slight mechanical deviation, spec. in the scale factor,
means the distance from one tag to the next in both of the directions x and y.
Temperature and humidity at the work bench could influence the distance as well as
new production series and different production techniques during the process like
material and temperature changes. Covering the complete x and y dimension of the
marker card, deviations of > 1 mm are noticeable. In order to be able to correct the
settings a special function is provided under menu > Extras > Elements> Scale factor.

Once a segment with a marker card is placed on
the EMS-2 the first upper left tag should be checked,
if the print is centered in both directions
(see also item 10 Calibration). There after the last tag
at the lower right corner needs to be printed in the

same

manner. If not printed exactly the same, the
scale factor for this particular card is

not perfectly correct

.

In order to correct the scale factor select one tag on the segment and choose > Extras
> Elements and > Scale factor from the menu.
The tags are changing into red and the EMS-2
moves with the inserted pen or magnifying tool
to the lower right corner to the point of the
beginning of the last tag.
With the button Pen Up /Down the plotter pen
or magnifying tool can be lowered in order to
find exactly the correct spot of the beginning of
the last tag at the lower right corner.
You can move the arm of the plotter with the four cursor buttons in
the pre-selected steps from 0.025 mm up to 10 mm, the default value is 0.1 mm.
After completion you must press the button Accept in order to save the changes to the
user file within the database, the general database is always kept original.
Closing the window moves the plotter arm back to the previous position.
The next start of the software will take the changed information from the user data-
base. You can return to the original values by clicking the Reset button.

The complete dimension in x and y direction can be changed with the correction of the
scale factor. Re-check the result of the print again by printing the last tag at the lower
right corner, centered in both directions.
