The present invention relates to a ribbon having a color erasing layer on a ribbon and a printing control method for forming a printing state clearly in order to make a printing state such as a character printed in a color printer clearly.

In the case of using a fabric color ribbon (Febric Color Ribbon) of the conventional general color printer, the printing surface of the printing head (dot head / daisy wheel) is a variety of colors.

That is, the color ribbon is formed at intervals of four colors such as black, blue, red, and yellow, and when the color printing is selected as the printing head, the various colors are buried on the printing surface, and in this state, except for black. In the case of printing to all colors, the color of the selected color is not properly printed because the color on the printing surface is unknown.

The color ribbon forms a white layer on the ribbon that can erase other inks in the structure, and in the method of using the ink ribbon, the color ink is printed after printing the white ink layer immediately before printing the color except white. Referring to the embodiment together with the accompanying drawings as follows.

The color ink ribbon (1) to which the present invention is applied is provided with a color array sequentially from the bottom to the top of the yellow (11), the red (12), the blue (13), and the black (14). In the state where the area of the color ink ribbon 1 is not increased, each of the existing color parts 11, 12, 13, 14 is slightly reduced to form one color part 15 to further increase the area of the ribbon. Form into 5 equal parts.

White is applied to the new color portion 15.

Printing four colors commonly used (yellow, red, blue, black) using a step motor and a cam (not shown) that rotates 720 times per step in printing with the color ribbon 1 having such a configuration. Immediately before the white part 15, the printing process is executed in a dark Full Graphic mode to erase each color on the printing surface and move to the desired color position to perform the printing operation.

The lifting mode of the printing process is as follows.

1.Black (72 ° up) → White → (44 ° down) → Blue (72 ° up) → Black

2. Black (72 ° up) → White → (216 ° down) → Red (144 ° up) → Black

3. Black (72 ° up) → White → (288 ° down) → Yellow (216 ° up) → Black

4. Black → Black

In the printing, the printing starts from the black portion 14 and is necessarily passed through the white portion 15 to the other color portions 13, 12, and 11. Because it is the most used.

Be sure to pass through the white portion 15 from the black portion 14 is that black ink is mixed with other colors, that is, blue, red, yellow upper portion (13) (12) (11), the ink color is mixed, blue, red This is because the yellow colors are printed into the mixed color, and black ink is wiped off the white upper portion 15, prints the desired color, and then moves to the white upper portion 15 to clean the color on the printing head and moves to another color portion.

The operation sequence of the present invention, as shown in FIG. 3, when the color change command comes in, the carriage having the print head mounted to the color change section is transferred to the left end, and moved 48 steps from the home position sensor to the left, and the upper portion of the white portion in the black portion 14 is shown. As shown in (15), a system graphic (Full Graphic Mode) is performed in the upper white part 15 state, and the position of the color ribbon 1 is changed to the desired color position.

After that, the carriage is transferred to the printing position in the printing section on the right side, and when the printing is completed in the desired color, the carriage is stopped and the position is changed to the black part 4 to wait for the next printing signal.

When the print signal comes in, a color change signal is received while printing the black portion 14 or printing the black portion 14.

Thus, when the color change command is received, the carriage with the print head mounted to the color change section is transferred to the left side.

As described above, the present invention places the white portion at the top of the color ribbon so that the black portion is printed or moved to the desired color portion through the white portion when receiving a color change signal at the black portion position, so that the printing state is always printed in a clear state. will be.

Claims (1)

The yellow portion 11, the red portion 12, the blue portion 13, the black portion 14, and the color portion 15 for the color eraser of the color ink ribbon 1 formed sequentially from the lower side to the upper side In the printing control method, when the printing head located in the upper black part 14 is moved to the other color parts 13, 12 and 11, it must pass through the upper white part 15 and then the selected color parts 13 and 12. Moving to (11), and when printing to the selected color is completed, to move to the upper black part (14) again.
