Longitudinal grating and setting roller for producing same

The utility model discloses a longitudinal grating. The longitudinal grating comprises a grating sheet. Grating lines on the grating sheet are longitudinally distributed along the grating sheet. The utility model also discloses a setting roller for producing the longitudinal grating. The setting roller comprises a roller surface and a roller shaft. Grooves and bumps on the roller surface are axially distributed in parallel to the roller shaft. According to the longitudinal grating for advertising printing and stereoscopic displaying, the grating lines are longitudinally distributed along the sheet, so that the breadth of the grating is greatly increased, and the problem of slightly small breadth of the conventional transverse grating when a large-sized printed product is printed is solved; in addition, the longitudinal grating can be spliced more easily than the transverse grating, so that influence on the stereoscopic displaying effect of the printed product due to low grating splicing quality can be reduced
