  A variety of paper were drawn by lead pencil with the grade between 4H
through 10B. Raman spectroscopy verified both G and D peaks on all the drawing
on PC print paper, PC photo paper, kent paper and paper for silver halide
print. After irradiation of scanning femtosecond laser, silver halide paper
drawn with 10B lead pencil remained surface flatness compared to the other
papers. Raman spectroscopy on silver print paper showed a large G peak with
less intensity of D peak. After irradiation of scanning femtosecond laser on
silver halide paper drawn by 10B lead pencil, Raman spectroscopy showed large G
peak and less intensity of D peak together with 2D peak around 2,700 /cm
corresponding to the existence of multi graphene.
