requires two (origin and scale) registration marks to accurately cut the die lines of most labels. If,
however, there is a problem with the printing it may become desirable to use three registration
marks. (see also discussion about marks in Tutorial Using Adobe Illustrator section)
When using two registration marks the embedded
computer in the i-TECH will automatically scan both
the Origin Point and the Scale Point. This is helpful
if the printing is skewed in relationship to the
carriage and or the x print size is not consistent or
not absolutely correct.
When using multiple registration points it is helpful
to understand the FO command and its parameters.
X, Y Scan offset
. This is the distance from the
skew point to perform the Y and X scans to find the
skew point. With the targets defined as above, the
+X, -Y is the correct signs for the scan offset for the
skew mark.
Skew Tab (Advanced Options)
(These menu items appear if you select the advanced
menu on the Setup Option menu)
Y Target Location
. This is the distance between the origin target and the skew target when the
2
nd
parameter of the FO command is –1. This command is used on CAD systems that do not emit
the FO HPGL command. You set up the initialization string to have
BJ1;FO-1,-1;
<for origin skew and scale processing>
or
BJ1;FO0,-1;
<for origin and skew processing>
This causes the cutter to look at the Y Target Location parameter from this menu item.
Scan Skew Point
-
A fourth scanning mode is implemented that performs scaling and
skewing by scanning only two marks (origin and scale). This method assumes there is no scaling
error in the Y-axis. (Specify the Origin, Skew, and Scale mode in your artwork software). By
checking the scan skew mark off, the i-TECH will only scan the Scale and Origin mark and
perform X-axis scaling and skew correction. This parameter should always be on unless your
printer driver does not support origin scale processing and you want to use origin scale processing.
Target Scan Direction
sets the direction of the scanning operation. The skew mark is normally
scanned
+X,-Y
Scale Tab
X, Y Scan Offset
. This is the distance
from the scale point to perform the Y and
X scans to find the scale point. With the
targets defined as above, the -X, +Y are
the correct signs of scan offset for the
scale target.
