JPS5929186A - Heat sensitive transfer dye ink tape used in dot matrix printer - Google Patents

Abstract

PURPOSE:To provide a thermal transfer ink ribbon used in a dot matrix printer conincided in the using frequency of each color and the occupation area of each color and reduced in wastefulness, constituted by distributing a black color part and color parts other than the black color part in a specific area ratio in a width direction. CONSTITUTION:Black, red, green blue and yellow printed by a five-color printer appear on a document in a ratio of 75:18:5:1:1. On the other hand, the min. necessary ink ribbon width in a dot matrix printer does not require the width of the type in a type printer and may be set to a width corresponding to one dot. Therefore, the black ink part 1 and ink parts 2 other than the black ink part in the thermal transfer ink ribbon used in the dot matrix printer may be provided so as to be distributed in an area ratio of 3:1-24:1 toward the width direction of the ribbon in coincided relation to use frequency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal transfer dye ink tape, and more particularly to a thermal transfer dye ink tape.
The present invention relates to a thermal transfer dye ink tube suitable for use in a processor.

Thermal transfer dye ink tape is made by laminating a polymer film and a dye ink layer.Heating the polymer film side, placing paper etc. on the dye ink 11μ (1), melting or sublimating the dye ink layer, It is something that is transferred onto the surface.Recently, manufacturing #Itlfle heater arrays has become a hot topic, and if you apply thermal transfer dye ink tape to a printer using Heater Array 2, you can obtain relatively high quality prints. Prints complicated characters such as kanji.It is suitable for printers that belong to kanji word processors.

Conventional thermal transfer dye ink tapes are often only black, which is commonly used in word processors, and some have black, red, stomach, yellow, green, etc. at intervals of one foot in the running direction of the tape, as shown in Figure 1. There is also one where each color is placed as a regular trap. A black-only thermal transfer dye ink tape can most effectively use one coat of each part of the tape, but in order to make the entire print stand out, it is preferable to use one coat of other colors. However, as shown in Figure 1, with heat-sensitive transfer dye ink tape in which each color is arranged at equal intervals in the running direction of the tape, it is used overwhelmingly in the black area, and one color is rarely reused, so there is a lot of waste. .

The present invention provides a color arrangement in which all parts of a thermal transfer dye ink tube can be effectively utilized.

The present invention achieves its purpose by reducing the area occupied on the tape by 14C each time each color is used.

Figure 2 shows all the results of investigating the proportions of each color that appear on a text printed with a five-color printer. As is clear from the figure, black and red are relatively used once, but A, green, and yellow are used significantly less frequently.

That is, if the occupied area 4* of each color of the thermal transfer dye ink tape composed of each color is the same as that shown in FIG. 2, and if a groove in which each color part can be fully utilized can be realized, the object of the present invention can be achieved. can. The area occupied by each color can be changed by arranging each color in the running direction of the tape as shown in FIG. +91J
For example, the black part r is 75 mm in the tape running direction, and the red part is 18 mm.
+++#I, it is also possible to arrange each of them in the repeating table ti times -J~. It is rare for the printed contents to be similar to this self-made 1-hood, even though it is a sword.
Black is 81. If you continue to pay, you will have to jump all 18 + qm of the red part and use the next black part. Also, it may be possible to rewind the red part to make full use of the skipped red part, but 18. It is difficult to take out a part with a width of πm km, and if the jump exceeds the number of blocks in the red part, it will be difficult to rewind accurately to the unused red part, and several blocks of red will not be used. Become.

However, if the frequency of use of each color and the area occupied by each color on the tape are matched, there will not be a large waste of tape. For example, if only black is printed, 25% of the tape
It's only a matter of time.

FIG. 3 shows an embodiment of the thermal transfer dye ink chip according to the present invention. Each color is arranged not in the running direction of the tape 1 but in the +iJ direction. Conventionally, there has been an English typewriter tape as a transfer ink tape as shown in FIG. 3, but in this case, the ratio of black to red parts was 1:1. However, in the thermal transfer dye ink tape of the present invention shown in FIG. 3, the ratio of black 1 to each color 2 other than black is close to 3:1. That is, the appearance ratio of black and each color other than black in FIG. 2 is made to match the occupied area on the tape.

This is possible because conventional English typewriters use the entire typeface for one character, but modern printers print characters as a collection of dots.
This is because printing is possible with at least a portion of the tape width. This printing method is called a dot matrix display method. For example, when one character is represented by 12 x 12 dots, the entire character is represented by whether or not the 12 dots are drawn vertically and horizontally. Even in this method, printing speed can be increased if the width of each color on the tape is equal to the vertical direction of one character (11), but printing is possible even if they are not equal, and the black part that is used most often is in the vertical direction of one character. It is best to set it to medium or above, and add the color of the pond in a width depending on the frequency of use.

As described above, the thermal transfer dye ink tape of the present invention is 1. Black color, which is the most commonly used color, can be printed at high speed.

2. Other colors can be printed at a slower speed, and unused portions can be rewound and used, so a utilization rate of nearly 100% can be achieved. (Rewinding is simpler than color division in the tape running direction).

The frequency of use of each color compared to Figure 2 is black, red, green, helmet, and yellow.
In the heart, 75%, 18%, 5%, 1%, 1%,
This is distributed across the width of the tape to determine the area occupied by each color. For example, in a thermal transfer dye ink tape with only black and red, the ratio of black and red should be 75=18, but in this case, 75:25, including the frequency of use of green and blue, is better. The actual character size ti, for example 12 point type, is approximately 4.4 mm, so the width of the black part is 4.4 +rr.
If m, the red part will be 1.5 questions, and the tape width will be 5.
It will be 9 mm. Furthermore, if the printer specifications are restricted and colors other than black are used only for horizontal lines, the frequency of each color being used will drop significantly.For example, if one character is represented by a 32x32 dot matrix, as shown in Figure 4. like sil
If one color of gold is placed in the width of the dot, it will look good, and the tape+iJ ratio of black and colors other than black will be 32=1 for one color other than black, and 32=3 for three colors other than black.

That is, if black and a color other than black are arranged in the I+1 direction of the tape and the ratio of their widths is 3:1 to 32:1, a relatively effective chive usage rate can be obtained.

As described above, the thermal transfer dye ink tape of the present invention is characterized by the area of black and colors other than black, and in particular, when each color is distributed in the width direction of the tape, the unused portion of the tape can be made into a large width. In theory, it is possible to achieve 100% usage rate.

In addition, the distribution of black and each color other than black is shown in @5 in addition to Figure 3.
As shown in the figure, each color 2 other than black may be distributed on both sides in the 11] direction with black l as the center.
