JPS58211483A - Correcting method of thermal transfer printing - Google Patents

Abstract

PURPOSE:To clearly print a new character on a covered-up part without any breaking in printed lines, by covering up the entire area of the range of the maximum character width and the maximum character height, when correcting by covering up with a thermal covering agent. CONSTITUTION:To correct a character 14 misprinted on a paper 12, a thermal correcting tape 6 and a thermal head 8 are operated to be in register with the character 14, and at least the range of the maximum character width and the maximum character height or a range slightly wider than said range is entirely covered up with the covering agent 6' of the tape 6. Thereafter, a new character 15 is printed at the covered-up part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a collection method in thermal transfer printing.

Conventionally, in the above-mentioned correcting method, as shown in Fig. 1, the same character shape as the character 1t to be corrected is covered with a cover wrap using a thermal coating material 2 (see Fig. 1 (b)). However, when a new character 3 is printed on that surface (FIG. 3(C)), the printing line is interrupted at the concave portion (dashed line in the same diagram), so the printing is not clear.

The present invention aims to eliminate the above-mentioned conventional drawbacks and to enable new characters to be clearly printed on the end surface of the cover wrap without any interruption in the printing lines.

The illustrated embodiment will be described below.

4 is a ribbon cassette of a printing device used directly in the uninvented method, which is mounted on a carrier (not shown);
A thermal print tape 5 is installed on the upper side, and a thermal collect tape 6 is installed on the lower side.

7.7 is a ribbon feeding roller provided on the rear side of the ribbon cassette 4, and 8 is a thermal head provided between both rollers 7.7.

The thermal head 8 has a plurality of heating elements 10 arranged in two vertical rows in a staggered manner on a vertically long rectangular support 9, with the heating elements 1σ at the lower end corresponding to the underlined portions of both rows. 1σ with the same height Δ
They are arranged so that they generate heat alternately (Figure 6).

11 is a plate-shaped platen, 12 is paper, and 13 is a paper feeding roller.

Therefore, in order to correct the letter 14 of rAJ among the letters 1cORRAcTJ printed on the paper 12 (FIG. 3) to the letter rEJ, the thermal correct tape 6 and the thermal head 8 are used to correct the letter 14 of the letter "A". Operate according to the location,
A range of at least the maximum character width and maximum character height (the character "
The entire surface of the range -p, which includes both A' and rEJ, or a slightly wider range is covered with the coating agent of the thermal collect tape 6 (FIG. 2 (a) and (b)).

Thereafter, the thermal printing tape 5 and the thermal head 8 are operated to match the cover-wrapped area, and the letter "E" is printed on the cover-wrapped surface (Fig. 2←→, Fig. 5).

In this way, the letter 14 of "A" is modified to the letter family 15 of "E", and the end face of the cover wrap is formed to correspond to the entire area including the letter "E", so that " The character 15 "E" is clearly printed without any interruption in the printing line.

As is clear from the above description, according to the present invention,
The entire area where the characters to be corrected are printed is covered with a thermal coating over at least the entire area of the maximum character width and maximum character height, that is, the entire area including both the characters to be corrected and the newly printed characters. Since the new characters are printed on the finished surface of the cover wrap, the new characters can be clearly printed without any interruption in the printing line even if the shapes of the two characters are significantly different.
