Table A-1 Temperature curve selection based on lens size and minimum object size
Temperature Curve
A B C D
Lens Size Min. Dimension, inches
80 mm > 0.30 0.29 – 0.16 0.15 – 0.08 < 0.07
125 mm > 0.47 0.46 – 0.25 0.24 – 0.13 < 0.12
200 mm > 0.74 0.73 – 0.39 0.38 – 0.20 < 0.19
370 mm > 1.37 1.36 – 0.73 0.72 – 0.37 < 0.36
Example – for our example lens size of 125 mm, follow the 125 mm row across until you nd a col-
umn containing a minimum dimension of 0.08". This is less than 0.12 inches, so Temperature Curve
D is the appropriate curve for this marking application.
The appropriate Temperature Curve is ______.

Determine the scale factor for the focusing lens used in this marking application from Table A-2
below.
Table A-2 Focusing lens scale factors
Lens Scale Factor
FLA 80 mm 2.466
FLA 125 mm 1.570
FLA 200 mm 1.000
FLA 370 mm 0.540
Example – in our series of examples, the Lens Size is 125 mm, so the Scale Factor is 1.570.
Scale Factor equals ______.
5
Determine the mark velocity (in inches per second—IPS) used in this marking application.
Marking Velocity equals ______ IPS.
6
Multiply the object’s Marking Velocity from Step 5 by the Scale Factor of the lens to obtain the Nor-
malized Marking Velocity.
Example – the Marking Velocity from Step 5 is 45 IPS and our Scale Factor is 1.570, so the Normal-
ized Marking Velocity is 70.65 IPS. You may round this value up to 71 IPS.
Normalized Marking Velocity equals ______ IPS.
