Abstract
When perforating a stencil material by a thermal head on the basis of image data, the smoothness of the stencil material is measured. The energy applied to the thermal head is increased as the smoothness of the stencil material becomes lower.
Claims7
A thermal head energy control apparatus, comprising:
- thermal head means for perforating a stencil material on the basis of image data;
- a measuring means which measures a characteristic value representing the smoothness of the stencil material;
- and
- an energy adjustment means which increases energy applied to the thermal head as the smoothness of the stencil material represented by the characteristic value measured by the measuring means becomes lower.
