An efficient surface enhanced Raman scattering(SERS)substrate was prepared by screen printing silver ink on drawing paper, white card paper and coordinate paper. The results showed that silver film/drawing paper represented the best SERS activity, followed by silver film/white card paper and silver film/coordinate paper. The minimum detection limits for crystal violet were 10-8, 10-7 and 10-7 mol·L-1, respectively. In addition, ten different positions were randomly selected on the same silver film/drawing paper surface, and the relative standard deviation values of the peak intensitiesat 913, 1 179 and 1 620 cm-1 were 13.2%, 12.5% and 10.6%, respectively, which indicated outstanding uniformity.
