Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting method for a printer having parallel pin heads, and more particularly to an adjusting method for bidirectional printing deviation.

[0002]

2. Description of the Related Art Conventionally, in a bidirectional printing misregistration adjusting method of this type of print processing apparatus, a person sets an adjusting value by means of setting an adjusting value, and printing is executed by a fixed value set experimentally. In this method, a person visually measures the print result and determines the optimum value.

Further, the adjustment value set by a human is a fixed value, so that the human has to perform again the readjustment and the resetting due to the deterioration of the mechanism.

[0004]

As described above, in the bidirectional printing misregistration adjustment of the conventional print processing apparatus, since the human is setting the experimental adjustment value, the adjustment time becomes long and the setting error is made. However, there is a disadvantage that the adjustment value cannot be set in real time.

The object of the present invention is to simplify the means for adjusting the print misalignment in both directions of the print processing device, prevent the setting error of the adjustment value from being induced, and automatically adjust the setting of the print misalignment adjustment value in both directions in real time. An object of the present invention is to provide a print processing device capable of performing the above.

[0006]

A bidirectional print misregistration adjusting method of the present invention comprises a print processing unit for performing print processing, an adjustment processing unit for adjusting bidirectional print misalignment, and an adjustment value for the bidirectional print misalignment by a program. An adjustment value setting unit for setting, an adjustment value calculation unit for calculating an optimum adjustment value, an image input processing unit for inputting an image of a print result by the print processing unit, and a pattern determination unit for determining a print pattern. Therefore, when the fixed pattern is printed by the judgment of the pattern judgment unit, the printing is executed by the preset bidirectional print deviation adjustment value set by the print processing unit, and the print result is input by the image input processing unit. Perform the operation, collect the image data in the adjustment value calculation unit, calculate the optimum value of the adjustment value,
The adjustment value setting unit may perform adjustment value setting processing by a program to automatically set the adjustment value in real time.

In FIG. 1, the control function of the print processing apparatus of the present embodiment includes a print processing unit 1 for performing print processing, an adjustment processing unit 2 for adjusting bidirectional print misalignment, and an adjustment value for setting an adjustment value by a program. A setting unit 3, an adjustment value calculation unit 4 for calculating an optimum adjustment value, an image input processing unit 5 for inputting an image of a print result, a pattern determination unit 6 for determining a print pattern, and a medium conveyance at the time of image input. It is composed of a medium transport unit 7 that performs processing and a control unit 8 that performs overall control.

Under the control of the control unit 8, the adjustment processing unit 2 performs the bidirectional printing deviation adjustment process using the already set bidirectional printing deviation adjustment value, and the printing processing unit 1 executes the printing. After that, the pattern determination unit 6 determines whether or not the print pattern is a pattern capable of calculating the bidirectional print misalignment adjustment value, and the determination result is a pattern capable of calculating the bidirectional print misalignment adjustment value. Under the control of the control unit 8, the image input processing unit 5 causes the print processing unit 1 to perform the conveyance of the printed medium in the medium conveying unit 7 in the discharging direction.
The result of printing is automatically input as an image.
After inputting the image, the optimum value of the bidirectional print deviation adjustment value is calculated by the adjustment value calculation unit 4 from the collected image data, and the calculated optimum bidirectional print deviation adjustment value is calculated by the adjustment value setting unit 3. Set automatically by the program without intervention.

At the time of executing the next print processing, the optimum bidirectional print deviation adjustment value set by the adjustment value setting section 3 under the control of the control section 8 is used to perform the bidirectional print deviation adjustment processing by the adjustment processing section 2 to perform the print processing. Printing is performed in section 1.

By repeating the above-mentioned printing process, simplification of the adjusting means, prevention of induction of setting error of the adjustment value, and change of the adjustment value due to deterioration of the printing mechanism or the like can be performed without human intervention. Achieve real-time and automatic settings.
