PRINTED MATTER WITH WOOGRAIN PATTERN

PROBLEM TO BE SOLVED: To eliminate an uneveness of a woodgrain pattern of a problem of a peeling product by sequentially aligning rectangular extended patterns gradually extended from a rectangular shape reference pattern perpendicularly to woodgrains, and expressing the woodgrain pattern regularly and continuously changing a unit of the reference pattern and the extended pattern. SOLUTION: In the printed matter 1 having a woodgrain pattern, a woodgrain design (swage bestard grain) of a natural three is input to a computer as image data by a CCD camera or the like, a rectangular reference design 2 in which a size of a direction perpendicular to the woodgrain and a size of a direction parallel to the woodgrain are predetermined values is formed. Then, a lower piece and a left piece of the design 2 are used as reference lines, the woodgrain pattern is constituted a predetermined magnification and enlarged, and five enlarged designs are, for example, manufactured. Then, it is trimmed so that distances from an intersection of the reference lines to points of side ends become equal so that rectangular enlarged designs 21, 22, 23, 24, 25 of the same shape as the design 2 are formed, these designs are sequentially aligned in a direction perpendicular to the woodgrain, and then printed on the base material.
