Pattern forming method for quartz surface and pattern forming device for quartz surface

A pattern forming device for quartz surface comprising:

• a transfer part for transferring a semi-finished product of quartz surface;
• a pattern forming part for forming a pattern on the semi-finished product of quartz surface conveyed by the transfer part;
• an additional pattern forming part for further forming at least one pattern on the semi-finished product of quartz surface in which the pattern is formed in the pattern forming part;
• and
• a color forming part for forming a color in the pattern of the semi-finished product of quartz surface formed in the pattern forming part,
• wherein the pattern forming part, the additional pattern forming part and the color forming part are positioned with a serial structure in order on the transfer part,
• wherein the pattern forming part comprises:
• a roller in which a disc shape or a spring shape with at least one curve is embossed;
• a motor for adjusting a speed of the roller;
• a first up-down adjustment unit for adjusting a height of the roller;
• and a first sensor for sensing a pattern formation position on a surface of the quartz surface.
