A cliché, comprising:

• a groove pattern,
• wherein the groove pattern comprises a region composed of a network pattern and the region composed of a network pattern is a square region comprising three or more intersection points of lines constituting the network pattern in the region and comprises a region in which a line width (W) and a depth (D) of the network pattern and a ratio (R) of a region which does not comprise the network pattern in the square region and an aperture line width (W0) of a mask pattern for forming a pattern, which corresponds to the network pattern, satisfy the following Relationship Equations 1 and 4.
• W=2D+W0+X [Relationship Equation 1]
• D≧33.8 exp(−R/0.235)+0.82 [Relationship Equation 4]
• wherein, X is a constant,
• D, W, W0 and X are values of micrometer units, and
• R is a value more than 0 and less than 1.
