DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording method and a recording apparatus, and more particularly to a method for forming a base on a paper such as a colored paper when a desired image is recorded after the base processing. The present invention relates to a recording method and a recording apparatus capable of preventing a decrease in recording quality due to stitching processing.

[0002]

2. Description of the Related Art In general, a thermal transfer printer, which is a kind of recording apparatus, is frequently used as an output device of a computer, a word processor or the like because of high recording quality, low noise, low cost, and ease of maintenance.

In such a conventional thermal transfer printer, a carriage is formed so as to be able to reciprocate along a platen, and a plurality of heating elements are provided on the carriage in a direction orthogonal to a recording direction called a printing direction. A thermal head formed in an aligned manner is mounted, and a ribbon cassette containing an ink ribbon of a desired color is detachably mounted.

[0004] Then, the ink ribbon and paper fed from the ribbon cassette are sandwiched between the platen and the thermal head, and the thermal head is reciprocated along the platen together with the carriage, and the ink ribbon is wound up. Meanwhile, by selectively energizing the heating elements of the thermal head based on the recording information for one line to generate heat, the ink of the ink ribbon is partially transferred to the sheet to record one line on the sheet. Then, the paper is fed by one line, which is referred to as a line feed operation, and the thermal head is driven again based on the recording information of the next line to record one line on the paper. By repeating the line feed operation and the recording operation, an image such as a desired character is recorded on a sheet.

When a color image is recorded on a sheet, three ribbon cassettes containing at least ink ribbons formed of three color inks of yellow, magenta and cyan are arranged, and each of the ribbon cassettes is mounted on a carriage. It is automatically exchanged between and is provided for recording.

In such a conventional recording apparatus, recording is performed based on recording information for one line, and then a line feed operation for one line is performed at a predetermined line interval to record the next line. The recording is theoretically performed such that the uppermost dot of the next recording information is located next to the lowermost dot position of the recording information. However, in practice,
It is the paper feed roller that transports the paper so that the uppermost dot of the next print information is located next to the lowermost dot of the print information, that is, transports the paper very accurately during a line feed operation. There is a limit to the dimensional accuracy and the like of each component constituting the paper feed mechanism, and it is extremely difficult to mechanically increase the paper transport accuracy.

Therefore, in order to improve the recording quality when an image is formed over a plurality of recording lines such as vertical ruled lines, stitching processing for smoothly connecting adjacent lines is performed. The stitching process is used to absorb variations in the accuracy of each component called mechanical variations. Generally, the stitching process uses the same recording information at the boundary between recording lines adjacent to each other at the time of recording, from several tens of microns to 100 dots corresponding to a head resolution of about 1 to 4 dots of a thermal head. It is configured to record over several tens of microns. That is, the stitching process is performed such that the border portions adjacent to each other overlap.

In recent years, various types of paper such as plain paper, cardboard, postcards, and OHP paper have been used as recording paper, and the color of the paper has been changed from transparent to red, blue, yellow, and so on. Various types of color paper such as black color paper are used. When recording is performed using such various kinds of paper, for example, when recording is performed using colored paper such as black or red, or when the color of the paper and the color of the ink recorded on the paper are the same or similar. For example, there is a problem that a good image cannot be recorded on a sheet.

Therefore, when color paper or the like is used as the paper, a background processing is performed on the paper before recording on the paper. This base treatment is performed by, for example, driving a thermal head using a base ink ribbon in which a base material is coated with white base ink to transfer the white base ink to paper. . The thickness of the base ink to be transferred to the paper is greater than the thickness of the ink used for recording. In particular, when using a white base ink, the concealment by the base ink is ensured. It is especially thick to make.

[0010]

However, in the above-described conventional recording apparatus, when the background processing is performed on the paper, the background stitching processing for positioning the adjacent background rows so that the boundary portions overlap each other is performed. Therefore, the base ink is superimposed on the boundary portion of the base line, and even if the adjustment is made by a method that reduces the amount of ink overlap caused by the base stitching processing when performing the base processing on the paper, the base stitching is performed. The thickness of the undercoat ink at the stitching position located at the boundary portion of the adjacent undercoat rows that have been subjected to the stitching process becomes considerably thick, stitching marks on the undercoat stand out, and the recording quality deteriorates.
There is a problem in that a difference in height occurs on the base, and as a result, when printing the ink on the ink ribbon used for printing on the base, printing failure of the ink on the ink ribbon used for printing occurs, thereby deteriorating printing quality. Was.

Further, since the stitching position by the base stitching process and the stitching position at the time of printing are the same, the ink used for printing at the time of transferring the ink of the ink ribbon used for printing onto the surface of the base is used. There is a problem that the transfer failure of the ink on the ribbon occurs at a higher probability, and the recording quality is further reduced.

The shape may be linear depending on the type of paper or the type of image to be recorded.

The stitching processing position set by the stitching processing position setting unit 39 is, for example, the base stitching processing position, the head resolution of the thermal head 7 from the stitching processing position at the time of recording for forming an image on the base surface. This is performed by shifting the generated heating elements by several dots.

The stitching processing position set by the stitching processing position setting unit 39 is most likely to be shifted from the stitching processing position when printing the background with cyan ink. It is preferable in order to avoid that the stitching processing position of the background where the trace is conspicuous and the stitching processing position of the cyan ink when recording with cyan ink on the background are overlapped.

The memory 32 stores a program for controlling the operation of each part such as the operation of moving the thermal head 7 toward and away from the platen 2 and the operation of transporting the paper by a paper feed mechanism (not shown), based on the recording information, and the carriage. 4, the presence or absence of the ribbon cassette 5, the type of the ink ribbon 17 stored in the ribbon cassette 5, the moving distance of the carriage 4 with respect to the home position, the open / close state of the canopy 19, A program for determining or detecting the distance or the like between a pair of ribbon cassettes 5 positioned apart or apart from each other;
And various programs such as a program for performing a known stitching processing operation for superimposing a boundary portion between recording lines adjacent to each other at the time of recording and connecting the lines smoothly. ing.

Next, the operation of the present embodiment having the above-described configuration will be described together with the method of the present invention.

In the present embodiment, the recording information input to the control unit 25 of the thermal transfer printer 1 from a host computer or an image reader (not shown) is separated into three colors of yellow, magenta and cyan to be used. The data is stored in the memory 32 as recording data for each color. Also,
The type of paper is stored in the memory 32 as paper data based on recording information input by a suitable input device (not shown) such as a host computer, an image reader, or a keyboard.

Next, the base stitching processing section 36 of the control section 25 determines whether or not to perform base processing based on the sheet data stored in the memory 32. The determination as to whether or not to perform the base processing is performed, for example, when the paper data is colored paper such as black that requires the base processing, it is determined that the base processing is required. It is determined that only the recording operation similar to the conventional one is performed without performing the base processing.

When the base stitching processing section 36 determines that the base processing is required, the base stitching processing section 36 places the thermal head on the boundary between the adjacent base rows in the base stitching processing. 7, the head resolution is about 1 dot, that is, the print resolution is 600
In the case of the DPI, a line feed operation for controlling the line interval between the base lines is performed so as to form a gap with a reference value of about 40 microns, which is one dot of the heating element.

That is, by forming a gap having a reference value of about 40 microns at the boundary portion between the base rows, even if mechanical conveyance accuracy varies, adjacent base rows adjacent to each other are formed. A gap of 2 dots or less of the head resolution of the thermal head 7 can be reliably formed at the boundary portion so that the boundary portion of the base row can be surely prevented from overlapping, so that stitching marks can be reliably formed from human eyes. It can be made inconspicuous. In other words, even when mechanical conveyance accuracy varies, the boundary portion of the base row is ideally located at the lowermost dot position of the recording information and the uppermost dot of the next recording information. The background stitching process is performed in the direction of providing a gap in the boundary part called the white line from the state where the gap of the boundary part which is a typical state is zero, and as a result, it is ensured that the boundary part of the base line overlaps Therefore, the stitching trace of the present embodiment can be made more inconspicuous from human eyes as compared with the stitching trace of the conventional stitching process in which the boundary portion of the base row is overlapped. Therefore, it is possible to reliably record an image with high recording quality even when a base is formed on a sheet.

In the present embodiment, when the base stitching processing unit 36 determines that base processing is required, the line spacing adjustment unit 37 determines the line spacing of the base line according to the type of paper used for recording. Can be adjusted, whereby the reference value of the gap formed at the boundary portion of the base line can be added or reduced in the range of, for example, about 10 microns. As a result, the paper quality of the paper can be adjusted. The stitching marks can be made inconspicuous from human eyes by absorbing the difference in how the stitching marks stand out depending on the type, etc., and performing a proper and uniform base treatment. Therefore, it is possible to more reliably record an image with high recording quality even when a base is formed on a sheet.

Further, in the present embodiment, when the base stitching processing section 36 determines that the base processing is required, the shape setting section 38 causes the boundary between the base rows adjacent to each other to be stitching marks. The shape of the portion is applied, for example, by energizing the lowermost dot of the heating element of the thermal head 7 located at the lowermost end of the recording information of the previous base row so as to thin out every several dots in the recording direction. The energization to the uppermost dot of the heating element of the thermal head 7 located at the uppermost end of the recording information of the underlying row is thinned out every several dots at the dot position where the energization was not performed in the preceding underlying row in the recording direction. The stitching is made non-linear by applying, which makes the stitching marks less noticeable to human eyes than the case where the stitching marks are linear. It is possible. Therefore, it is possible to reliably record an image with high recording quality even when a base is formed on a sheet.

Further, in this embodiment, when the base stitching processing section 36 determines that the base processing is required, the stitching processing position setting section 39 sets
For example, the base stitching processing position is shifted from the stitching processing position at the time of recording for forming an image on the surface of the base by several dots of the heating element which is the head resolution of the thermal head 7, and as a result,
Since the stitching trace due to the base stitching process and the stitching trace due to the stitching process at the time of recording do not overlap, the transfer failure when transferring the ink of the ink ribbon 17 used for recording onto the surface of the base is more reliably prevented. Therefore, recording of an image with high recording quality can be performed more reliably.

The base stitching process in this embodiment is performed using a base ink ribbon 17d made of white base ink for base processing stored in the ribbon cassette 5d.

The underlayer processing operation of the paper will be described more specifically.

The paper base processing operation is started by detecting the ribbon cassette 5d containing the base ink ribbon 17d made of white base ink used for the base processing. The detection operation of the ribbon cassette 5d is performed by a control command from the control unit 25, for example, as shown in FIG.
By moving the carriage 4 located in a non-mounted state in which the ribbon cassette 5 is not mounted at the home position provided at the left end in FIG. 1 in the right direction in FIG. This is performed by detecting the identification mark 23 of.
Then, the optical sensor 18 sends a unique detection signal of each identification mark 23 based on the arrangement and pitch of the non-reflecting portions 24a to the control unit 25, and the control unit 25 identifies the ribbon cassette 5d corresponding to the control command. It is determined whether or not the mark is the mark 23. If the identification mark 23 of the ribbon cassette 5d corresponds to the control command, the movement of the carriage 4 is stopped. If the identification mark 23 is not the identification mark 23 of the ribbon cassette 5d corresponding to the control command. The movement of the carriage 4 is continued until the identification mark 23 of the ribbon cassette 5d corresponding to the instruction is detected. Thereafter, the carriage 4 is stopped at a position facing the corresponding ribbon cassette 5d, the parallel crank mechanism 8 and the rotary crank mechanism 11 are driven to raise the upper carriage 4b, and the base ink ribbon held by the cassette holder of the canopy 19 is held. The ribbon cassette 5d containing 17d is transferred to the upper carriage 4. And
Again, the parallel crank mechanism 8 and the rotary crank mechanism 11 are driven to lower the upper carriage 4b so as to contact the lower carriage 4a. As a result, the carriage 4 is in a mounted state in which the ribbon cassette 5d containing the base ink ribbon 17d is mounted.

Next, a predetermined paper is transported between the thermal head 7 and the platen 2 by a known paper feeding mechanism (not shown) to the position of the first row for recording the background, and the cue for the background processing is performed. Then, the thermal head 7 is placed on the platen 2 via the base ink ribbon 17d and the paper.
In this state, the carriage 4 is moved along the platen 2 and the control unit 25 controls the heating element of the thermal head 7 while winding the base ink ribbon 17d. By generating heat by energizing, the base ink ribbon 17d
The white base ink is transferred to a sheet, white recording is performed on the sheet, and the base processing of the first base line is performed. When performing the base processing of the first base row, in order to make the shape of the boundary portion with the next base row non-linear, a gap is formed between the dots of the lowermost heating element to be energized. The energization is controlled ON / OFF every several dots in the recording direction by the setting unit 38, and
In order to make the base stitching processing position different from the stitching processing position at the time of recording that forms an image on the surface of the base,
The position of the base line is different from the position of the sheet at the time of recording.

By setting the cueing positions at the same time during the base processing and at the time of recording, and by preventing current from flowing to, for example, three dots at the lowermost end of the heating element of the thermal head 7 during the base processing, the base stitching processing is performed. The position may be different from the stitching processing position at the time of recording for forming an image.

Next, a predetermined sheet is conveyed to a predetermined position by a known paper feed mechanism (not shown) to perform a line feed operation. At this time, the line spacing between the adjacent base lines due to the conveyance of the paper is approximately one dot of the head resolution of the thermal head 7 at the boundary between the adjacent base lines.
In the case of 00 DPI, a gap is formed with a reference value of about 40 microns, which is one dot of the heating element. By setting the reference value of the gap formed at the boundary portion between the base rows adjacent to each other to about 40 microns,
Even when the accuracy of each component such as the paper feed mechanism varies, it is possible to position the components so that the border portions of the adjacent base lines do not overlap. Note that the line spacing between adjacent base lines is adjusted and used by the line spacing adjustment unit 37 according to the type of paper, so that the gap formed at the boundary between the adjacent base lines is Is used after being increased / decreased with respect to the reference value depending on the type. Furthermore, it is not preferable to form an excessively large gap at the boundary between the adjacent base rows because the gap becomes conspicuous as a stitching mark. The limit that can prevent this gap from being noticeable as stitching traces varies depending on the number of inks used for recording to be overlaid on the surface of the base, the combination of the color of the base and the color of the image to be printed, etc.
By setting the gap to 2 dots or less of the head resolution of the thermal head 7, stitching traces can be reliably made inconspicuous from human eyes.

Next, the thermal head 7 is brought into a head down state in which the thermal head 7 is pressed against the recording surface 2a of the platen 2 via the base ink ribbon 17d and the paper, and the carriage 4 is moved along the platen 2 in this state. At the same time, while the base ink ribbon 17d is being wound, the heating element of the thermal head 7 is energized by the control unit 25 to generate heat, thereby transferring the white base ink of the base ink ribbon 17d to the paper. The white recording is performed on the sheet, and the base processing of the next line is performed. When the base processing of the next base row is performed, power is supplied to all the dots of the heating elements, and the gap shape setting unit 38 supplies power to the dots of the uppermost heating element in the recording direction. The ON-OFF control is performed directly opposite to the ON-OFF control of the energization in the recording direction for the dot of the lowermost heating element to be energized in the preceding row. This makes it possible to make the shape of the boundary between the adjacent neighboring rows non-linear. For the dots of the lowermost heating element, ON-OFF control of energization in the same recording direction as the preceding base row is performed.

The line feed operation and the background processing for each line are performed in the following order. The background processing for the last background row in the recording area is as follows.
This is performed by controlling the number of heating elements to be energized, and the ON of energization in the recording direction is performed for the dot of the uppermost heating element to be energized by the shape setting unit 38.
The OFF control is performed directly opposite to the ON-OFF control of the energization in the recording direction for the dot of the lowermost heating element to be energized in the preceding row. In addition, for the lowermost dot to be energized, all energization is performed in the recording direction.

By transferring the white base ink to at least the entire recording area of the sheet in this way, the base processing is completed.

Next, when the base processing is completed, ink is transferred onto the base in the order of yellow, magenta, and cyan by using the ribbon cassettes 5a, 5b, and 5c in the same manner as in the related art, thereby obtaining a desired color. An image is recorded. Also, when transferring images of yellow, magenta, and cyan to the base, when the image straddles each recording line, such as a vertical ruled line extending over a large number of lines, a stitch that overlaps the boundary portion of the recording lines as in the related art is used. Is performed. Furthermore, the stitching processing position at the time of recording for forming an image on the surface of the base is different from the base stitching processing position at the time of forming the base. By setting the stitching processing position of the base and the stitching processing position of the cyan ink when recording with the cyan ink on the base to be particularly different positions, it is possible to reliably form the most prominent stitching marks. Can be prevented.

Furthermore, the surface of the thermal head 7 is generally cleaned by a well-known cleaning mechanism (not shown) every time recording of each color is performed or at a predetermined use time. .

In the stitching process at the time of recording a color image on the surface of the base, similar to the base stitching, the border portions of adjacent recording lines are positioned so as not to overlap. When the yellow, magenta, and cyan inks are transferred to the surface of the base, the stitching process may be different for each color.

As described above, according to the thermal transfer printer 1 of the present embodiment, when the base processing is performed on a sheet such as a case where a color image is recorded on a sheet such as a color sheet, the base ink such as white is used. It is possible to perform a base stitching process of positioning the border portions of the adjacent background rows recorded on each other so as not to overlap,
By performing the base stitching process in the direction of providing a gap from the state where there is no gap at the boundary portion of the base row, that is, the so-called white line direction, it is possible to make the stitching marks visible to the human eye inconspicuous. However, the thickness of the base ink generated by the base stitching process in which the base ink is overlapped at the boundary portion of the conventional base row becomes considerably thick, and the stitching marks of the base are conspicuous, the recording quality is reduced, and the height of the base is high or low. The difference is made,
At the time of recording in which the ink of the ink ribbon used for recording is transferred to the surface of the base, it is possible to reliably prevent the inconvenience that the transfer of the ink of the ink ribbon used for recording occurs and the recording quality is degraded. Even when an underlayer is formed, high-quality recording can be reliably performed.

Further, according to the thermal transfer printer 1 of the present embodiment, the thermal resolution of the thermal head 7 is set at the boundary between the adjacent background rows when performing the background processing on the paper.
By providing gaps smaller than dots, even when there is variation in the accuracy of each component such as the paper feed mechanism, it is possible to prevent the border portions of the adjacent base rows from easily overlapping each other, Stitching marks at the boundary can be easily made inconspicuous.

Further, the thermal transfer printer 1 of the present embodiment
According to the method described above, the line spacing between adjacent background lines when performing background processing on paper can be adjusted according to the type of paper, so the difference in how stitching marks stand out depending on the type of paper. Can be easily absorbed, so that
Appropriate recording quality can be ensured for various types of paper, and more types of paper can be used.

Further, according to the thermal transfer printer 1 of the present embodiment, the shape of the boundary portion between the adjacent background rows when performing the background processing on the sheet can be formed in a non-linear manner. Since the stitching marks located at the borders between adjacent rows of the base line in the base stitching process when forming the base on the paper are not linear, the stitching marks are made less noticeable to human eyes. be able to.

Then, the thermal transfer printer 1 of the present embodiment
According to this method, the base stitching processing position at the time of forming the base and the stitching processing position at the time of recording for forming an image on the surface of the base can be formed at different positions. Since the stitching position at the time of recording does not overlap the stitching position, it is possible to reliably prevent the transfer failure of the ink of the ink ribbon used for recording to the base material caused by the thickening of the conventional ink. Even when an underlayer is formed, high-quality recording can be reliably performed. By setting the stitching processing position of the base and the stitching processing position of the cyan ink when printing with the cyan ink on the base to be particularly different positions, the stitching marks which are most conspicuous when recording a color image are obtained. Formation can be reliably prevented.

In the present embodiment, the thermal transfer printer 1 capable of forming a color image has been described as an example. The thermal transfer printer 1 capable of forming a color image is referred to as a multi-color ink ribbon. A recording area composed of a white base ink used for forming a base on one ink ribbon to be formed and at least a total of four inks of at least three inks of yellow, magenta and cyan used for printing is formed. A ribbon cassette containing an ink ribbon in which different colors are arranged adjacent to each other repeatedly in a direction may be used. That is, a single ribbon cassette may be used instead of replacing a plurality of ribbon cassettes. . In this case, it is not necessary to store a program for automatically replacing the ribbon cassette 5 in the memory 32 of the control unit 25.

Further, the recording device may be a device that transfers monochromatic ink to a sheet. In this case, the recording information for recording is stored in the memory 32 of the control unit 25 as recording data corresponding to the head resolution without color separation.
At the time of actual printing, print data is output to the controller 33, and the controller 33 selectively drives any one of the plurality of heating elements of the thermal head 7 according to the print data to generate heat. Good. Further, when performing the base processing operation, the ribbon cassette 5 in which the base ink ribbon 17 d is stored with respect to the carriage 4.
A configuration in which the user manually replaces d, that is, a configuration in which the ribbon cassette 5d in which the base ink ribbon 17d is stored is not held in the cassette holder in advance and the ribbon cassette 5 is not automatically replaced may be employed. In this case, it is not necessary to store a program for automatically replacing the ribbon cassette 5 in the memory 32 of the control unit 25.

When performing the base processing, the base stitching processing for positioning the borders of the base rows adjacent to each other so as not to overlap with each other is performed by the stitching processing unit 3.
6 may be stored with a program capable of adjoining a boundary portion between adjacent background rows. As a specific example of the program capable of making the boundary portions of the base lines adjacent to each other adjacent to each other, the paper feed amount is set so that the variation in the transport amount of the paper that differs for each of the assembled apparatuses is set to an appropriate transport amount. It is preferable that the control is performed by correcting the transport amount when the paper is transported by the mechanism, that is, by correcting and controlling the number of steps of the step motor. The correction of the transport amount of the paper when the border portions of the adjacent base rows are positioned adjacent to each other is performed when recording an image on one sheet of paper in consideration of the wear of the paper feed roller and the like. Although the time and the economic burden are increased, not only are the adjustments made at the time of shipment of the apparatus, but also each time the recording operation is performed in the memory 32 of the control unit 25 or every time the recording operation is performed a predetermined number of times, When performing cueing of the paper, the amount of paper transported is detected by an optical sensor or the like, and the detected transport amount of the paper is compared with an appropriate transport amount of the previously stored paper. It is preferable that the number of steps of the step motor is controlled so that an appropriate amount of paper is transported.

The present invention is not limited to the above embodiment, but can be variously modified as needed.
