BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a building board, a designed surface of which is printed, and a printing method used for the board. [0003] 2. Description of the Prior Art [0004] A joint method by which building boards are jointed according to shiplap joint will be explained, referring to FIG. 7 and FIG. 8. FIG. 7 is a perspective view showing a jointing state in which right and left building boards are jointed according to the joint method by shiplap joint. As shown in the drawing, according to the joint method by shiplap joint, a fastening member 72 is locked to lower shiplap portions both of which are located over an abutting joint portion 71 formed with abutting building boards 100A and 100B, and the fastening member 72 is fixed on a furring strip 73 with nails. [0005] FIG. 8 is a schematic sectional view showing a jointing state by shiplap joint. As shown in the drawing, a jointing state by shiplap joint in which jointing of right and left building boards is realized by putting the upper shiplap portion 120B formed in the end portion of the left-side of the building board 100B disposed on the right side on the lower shiplap portion 110A formed in the end portion of the right-side of the building board 100A disposed on the left side. Moreover, a caulking compound 81 is provided to the lower shiplap portion 110A beforehand, and is pressed by the upper shiplap portion 120B so as to function as a dam against rainwater which enters from the abutting joint portion 71. Accordingly, water is prevented from leaking to the back side (the inside of a house) of the building board after construction. [0006] As all operations necessary for butt jointing in which a sealing material is applied to an abutting joint portion are not required at all by the above-described shiplap jointing, the workability is increased, and, at the same time, the appearance after construction is greatly improved. Obviously, neither spoiling of the appearance due to secular changes in the sealing material nor water leak based on deterioration of the material occurs. [0007] FIG. 9A and FIG. 9B are views, each explaining a construction method of building boards as an external wall. When building boards 100A, 100B, and 100C, all of which have shiplap portion in every direction for the joint method by shiplap joint, are fastened to an external wall as shown in FIG. 9A, the building board 100A disposed on the left side is fastened to a column (structural building frame) in the first place, and, then, the building board 100B disposed on the right side of the board 100A is arranged in the jointing state by shiplap joint (a state in which the upper shiplap portion 120B formed in the left side of the building board 100B is put on the lower shiplap portion 110A formed in the right side of the building board 100A), and is fastened to the column. Subsequently, the building board 100C disposed over the building board 100A is arranged in the jointing state by shiplap joint (a state in which the upper shiplap portion 120C formed in the lower side of the building board 100C is put on the lower shiplap portion 110A formed in the upper-side of the building board 100A), and is fastened to the column. A fastening member as shown in FIG. 7 is used for the fastening. [0008] FIG. 9B is a view showing a state in which the three building boards 100A, 100B, and 100C are jointed. The fastening members (not show in the drawing) are fixed to the column for arranging the building boards. However, in the case where the fastening member is fixed to the column at the upper end of abutting portion 72 between the two building boards 100A and 100B respectively arranged on the right and left sides, the fastening member is fixed approximately horizontally to the column while correcting pattern shifts between the right and left building boards and the like. [0009] A gap between the building boards in the abutting joint portion 71 will be explained, referring to FIG. 10A and FIG. 10B. The designed surfaces of the building boards 100A and 100B include pattern convex portions 101A and 101B, and joint portions 102A and 102B. FIG. 10A is a view showing a case in which the distance between the abutting two building boards in the abutting joint portion 71 is equal to a designed value. The pattern convex portions on the right and left building boards are physically divided into parts in the abutting joint portion 71. However, when the patterns on the building boards are designed in such a way that a part of the pattern convex portion 101A on the building board 100A disposed on the left side and a part of the pattern convex portion 101B on the building board 100B disposed on the right side form one pattern convex portion, the pattern continuity between the right and left building boards may be secured in appearances. [0010] FIG. 10B is a view showing a constructed state in which the distance between the two abutting building boards in the abutting portion 71 becomes larger than the designed value, and the two building boards are mutually shifted by a distance DELTA d in an up and down direction, based on errors in the cutting size and the like. In this case, a feeling of pattern mismatching (a feeling of wrongness) is caused because the pattern continuity between the pattern convex portions cannot be secured in appearances as shown in FIG. 10A. [0011] Incidentally, in order to secure the pattern continuity between the right and left building boards, it is required to consider how to color both of the pattern convex portions, other than how to continuously form both of the pattern convex portions, which are physical shapes of the designed surfaces of the building boards, on the right and left building boards as described above. Japanese Patent Laid-Open No. 3284037 has disclosed a painting technology for coloring patterns as a method by which pattern continuity between abutting building boards is realized. [0012] Generally, there is an apprehension that the width of a abutting joint portion formed between abutting building boards in a ceramics system (in a cement system) becomes different from a designed value when the building board is used on the external wall of a building, because the building board is by no means manufactured without dimensional errors. Accordingly, defective construction is caused, and pattern shifts between right and left building boards is brought in appearances. Moreover, the width of an abutting joint portion is changed by secular changes after construction, that is, by repeated expansion and contraction of an building board in some cases to cause pattern shifts between right and left building boards, and the appearance is largely spoiled. SUMMARY OF THE INVENTION [0013] An object of the present invention is a configuration in which a feeling of wrongness is not caused by securing pattern continuity between pattern convex portions in appearances even when the widths of abutting joint portions formed between abutting building boards are different from each other by defective construction and secular changes after construction, and shape shifts between pattern convex portions are caused. [0014] According to the present invention, in a building board having a designed surface with pattern convex portions, and upper and lower shiplap portions, both of which are formed in the end portion of the designed surface, a printing extension portion is printed in the lower shiplap portion in such a way that the extension portion and the above-described pattern convex portion are continuously formed. [0015] According to the present invention, a feeling of wrongness is not caused in appearances by securing pattern continuity between pattern convex portions of two abutting building boards even when the width of an abutting joint portion formed between the abutting building boards is large, and a position shift between the boards is caused.
