Then, the data correction unit 97 performs, on the image data, the first correction process indicated by the acquired correction process information “A” from among the three types of correction processes.

  The correction process performed on the image data will be described with reference to FIGS. Three types of correction processing are prepared corresponding to three types of label application surfaces F having different curvatures. Each correction process corrects the distortion of the printed image G when the label L is applied to the label application surface F, which is a curved surface. That is, in each correction process, the label L on which image data that has not been corrected is applied to the plane Fa when the label L is attached to the label application surface F that is a curved surface. In this case, the image data is corrected so as to be equivalent to the appearance of the print image G in the case. In the following, the label L on which uncorrected image data is printed is referred to as “uncorrected label L0”, and the printed image G printed on the uncorrected label L0 is referred to as “uncorrected image G0”. The label L on which the corrected image data is printed is referred to as “corrected label L1”. The print image G printed on the corrected label L1 is referred to as “corrected image G1”.

In the first correction process, as shown in FIG. 5, the appearance of the corrected image G1 when the corrected label L1 is applied to the label application surface F having a curvature of 1 / r ₁ is not corrected to the plane Fa. The label L0 is corrected so as to be equivalent to the appearance of the uncorrected image G0 when the label L0 is attached. That is, in the first correction process, the aspect ratio (horizontal: vertical) of the image data is corrected to 1: S ₁ (S ₁ > 1). Note that the aspect ratio of the image data before correction is 1: 1.

In the second correction process, as shown in FIG. 6, how the corrected image G1 appears when the corrected label L1 is applied to the label applying surface F having a curvature of 1 / r ₂ (r ₂ <r ₁ ). Is corrected to be equivalent to the appearance of the non-corrected image G0 when the non-corrected label L0 is attached to the plane Fa. That is, in the second correction process, the aspect ratio of the image data is corrected to 1: S ₂ (S ₂ > S ₁ ).

In the third correction process, as shown in FIG. 7, how the corrected image G1 appears when the corrected label L1 is applied to the label application surface F having a curvature of 1 / r ₃ (r ₃ <r ₂ ). Is corrected to be equivalent to the appearance of the non-corrected image G0 when the non-corrected label L0 is attached to the plane Fa. That is, in the third correction process, the aspect ratio of the image data is corrected to 1: S ₃ (S ₃ > S ₂ ).

  The correction image formation A and the correction image B will be described with reference to FIGS. The tape T on which the correction image B is formed is referred to as a correction image formation A. The correction image formation A is printed with an identification mark M (here, a number) indicating the type of the correction image B together with the correction image B. The correction image B is formed on the tape T by the tape printer P printing the correction image data stored in the data storage unit 935. The correction image B may be printed by another printing apparatus that has received the correction image data from the tape printing apparatus P. Further, the correction image formation A is not limited to the correction image B printed on the tape T, and may be one printed on a cut sheet, for example. The user may use the correction image formation A prepared in advance, or may create the correction image formation A by handwriting the correction image B.

The correction image B has a plurality of indices Ba arranged at non-equal intervals. Three types of correction images B are prepared according to three types of label application surfaces F having different curvatures corresponding to the three types of correction processing. That is, in the first correction image B1, when the correction image formation A is placed along the label affixing surface F having a curvature of 1 / r ₁ , a plurality of indicators Ba appear to be arranged at equal intervals. The correction image-formed product A is aligned so that the alignment direction of the plurality of indices Ba matches the circumferential direction of the label attaching surface F. Similarly, in the second correction image B2, when the correction image formation A is placed along the label affixing surface F having a curvature of 1 / r ₂ , a plurality of indices Ba appear to be arranged at equal intervals. . Further, in the third correction image B3, when the correction image formation A is placed along the label affixing surface F having a curvature of 1 / r ₃ , a plurality of indicators Ba appear to be arranged at equal intervals.

  Based on FIG. 10, a series of operations performed by the tape printer P regarding the correction processing will be described.

  The tape printer P displays a correction necessity selection screen D1 on the display 2 when a print execution operation is performed on the operation panel 1. On the correction necessity selection screen D1, choices “Yes” and “No” are displayed together with a message “Do you want to execute image distortion correction?”.

  When “Yes” is selected on the correction necessity selection screen D1, the tape printer P displays a correction image selection screen D2 on the display 2. When “No” is selected in the correction necessity selection screen D1, the tape printer P performs printing based on the uncorrected image data without displaying the correction image selection screen D2 on the display 2. Run.

  On the correction image selection screen D2, the message “first correction image”, “second correction image”, and “third correction image” are displayed together with a message “Which correction image appeared at regular intervals?”. The “Image” option is displayed.

  Here, when the three types of correction image formations A are placed along the label application surface F, the user can see a plurality of indicators Ba arranged at the most equal intervals from the three types of correction images. A correction image B is selected. Then, the user selects an option corresponding to the selected correction image B on the correction image selection screen D2. Then, the image information acquisition unit 95 acquires image information based on the option selected on the correction image selection screen D2.

When “first correction image” is selected on the correction image selection screen D2, the image information acquisition unit 95 acquires the image information “a”. In this case, as described above, the correction processing information acquisition unit 96 acquires the correction processing information “A” from the information storage unit 936, and the data correction unit 97 performs the first correction processing on the image data. Accordingly, an aspect ratio of 1: corrected label L1 which corrected corrected image G1 is printed on S ₁ is obtained. In the correction image selection screen D2, when the "second correction image" is selected, and so on, an aspect ratio of 1: S ₂ corrected label L1 which corrected corrected image G1 is printed on the can get. Further, the correction image selection screen D2, when the "third correction image" is selected, an aspect ratio of 1: corrected label L1 which corrected corrected image G1 is printed on S ₃ is obtained.

Here, when three types of correction image-formed products A are placed along the label application surface F, the correction image B in which the plurality of indexes Ba appear to be aligned at the most equal intervals is, for example, the first correction image. If it is B1, the curvature of the label applying surface F is approximately 1 / r ₁ . In this case, the user, for selecting the first correction image B1 in the correction image selection screen D2, the aspect ratio is 1: corrected label L1 which corrected corrected image G1 is printed on S ₁ is can get. Therefore, the corrected label L1 which were obtained, the curvature is adhered to the label sticking surface F is about 1 / r _1, the appearance of the post-correction image G1 is uncorrected label L0 is attached to the plane Fa This is equivalent to how the uncorrected image G0 appears.

Correction processing suitable for F can be performed on the image data.

The tape printing apparatus P according to the present embodiment further includes an information storage unit 936 and a correction processing information acquisition unit 96. The information storage unit 936 stores three pieces of image information indicating three types of correction images B and three pieces of correction processing information indicating three types of correction processing in association with each other.
