Task:
In large printing houses, the alignment
of the paper is extremely important. On
many occasions, a printing alignment
line is also used. With this line, the

printer head and paper. Camera sys‐
tems have been used to manage this
task, but due to lighting and different
print line colors, repeated setup is
often needed. The customer requires
an accuracy of 0.1 mm with the dis‐
tance from Line to edge calibrated to
13 mm.
