Description

  The present invention relates to a method for producing a multicolor printing sample.

  New pattern printing production by a screen printing machine is performed after creating a first-found book and a swatch book.

By the way, in the case of making a 3-20 m first-finding book and a swatch book using an automatic screen printing machine, a sample printing cloth is pasted on an endless belt, and the number of colors is added to this. In addition, a plurality of screen printing units are arranged, and the fabric to be printed is intermittently sent, and when the endless belt is stopped, the screens of the plurality of screen printing units are lowered all at once to perform the printing operation. When the number of colors used in the printing sample is N, N screens are used as the plurality of screens. Each time the fabric to be printed is conveyed by 1 pitch, printing with the N screens is repeated. The printing sample was completed after passing through N screens.

  However, since the screen frame is arranged every 2 times (2P) the feed pitch length P of the printed fabric in consideration of the protrusion of the screen printing unit mold, it is necessary to complete the printing sample for one sample. There is a problem that a 2NP-long printed fabric is required. Further, there is a risk of lateral flow during normal rotation of the belt, so that a mold matching operation is required for each printing unit. Furthermore, since a guide cloth is required to finely adjust the position of each screen frame, there is a lot of waste in terms of materials, labor, and creation time.

  On the other hand, when an attempt is made to use a sample printing machine, it is difficult to obtain the same quality as the product.

The present invention provides a method for producing a printing sample, which can improve the efficiency of materials and labor and shorten the production time, and can assure the same quality as the production product.

The inventor of the present invention has been completed through intensive studies in order to solve the above problems.
1. Automatic equipped with an endless belt, a screen printing unit, and multiple types of screens for multi-color printing, and by intermittently transporting the fabric to be printed at the required feed pitch by the endless belt, printing is performed when the endless belt is stopped Using a screen printing machine, a sample printing cloth is pasted on the surface of the endless belt, and the printing cloth is intermittently sent to the printing position where the screen printing unit is installed by forward rotation of the endless belt. A printing process to be performed, and a cueing process for returning the head in the moving direction of the fabric to be printed at the time of normal rotation of the endless belt to the original printing position by reverse rotation of the endless belt after printing by the printing process, While repeating the process and the cueing process alternately, each time the printing by the printing process is completed, the screen printing unit By exchanging bets screen, it provides a method of creating printing sample which is characterized in that a plurality of colors printing.
2. Automatic equipped with an endless belt, a screen printing unit, and multiple types of screens for multi-color printing, and by intermittently transporting the fabric to be printed at the required feed pitch by the endless belt, printing is performed when the endless belt is stopped A screen printing machine is used to attach the sample print cloth to the surface of the endless belt, and the endless belt is rotated forward to intermittently send the print cloth to the printing position where the screen printing unit is installed. A printing process by forward transfer, and after printing by a printing process by normal transfer, printing is performed by returning the fabric to be printed to the original printing position by intermittent feed by reverse rotation of the endless belt, and a printing process by reverse feed The printing process by forward transfer and the printing process by reverse feed are alternately repeated, and By printing by step to exchange screen of the screen printing unit each time to end, it provides a method of creating printing sample which is characterized in that a plurality of colors printing.
3. The method for producing a printing sample according to 1 or 2 above, wherein one screen printing unit is set at a printing position.

  According to the method for creating a printing sample according to claim 1, while repeating the printing step and the cueing step alternately, by replacing the screen of the screen printing unit every time printing by the printing step is completed, Since multi-color printing is performed, it is not necessary to dispose a plurality of screen printing units every twice the feed pitch length P as described above, and the length of the sample fabric to be printed can be saved.

  Also, after printing in the printing process, it has a cueing process that returns the beginning of the movement direction of the fabric to be printed to the original printing position by reversing the endless belt, so that it can be used for short samples. In the case of using a fabric to be printed, compared to the case where the endless belt is rotated forward after the printing is completed, the head can be positioned in a short time, and the production time can be shortened.

  In addition, since the error caused by the forward rotation can be canceled by reversely returning to the original position, it is not necessary to adjust the positioning of the fabric to be printed for preventing the pattern deviation. In addition, since a guide for finely adjusting the position of each screen frame is not required, efficiency can be improved in terms of materials, labor, and creation time.

According to the method for preparing a printing sample according to claim 2, the reverse feeding is carried out after returning to the original printing position by intermittent feeding of the fabric to be printed by reverse rotation of the endless belt after printing by the printing process by forward transfer. Therefore, by performing printing while returning the cloth to be printed to the original position by reversing, it becomes unnecessary to cue the printed cloth, and the production efficiency can be further improved.
According to the method for creating a printing sample according to claims 1 and 2, since the printing sample is created using the production machine, the reproducibility is excellent and the quality equivalent to the product can be ensured.
In addition, since one screen printing unit is set at the printing position, multicolor printing can be performed using the same printing unit, so that mold matching becomes unnecessary and work efficiency can be improved.

Embodiment 1
The printing sample preparation method of the present embodiment is to perform printing on the sample fabric 1 using the automatic screen printing machine A shown in FIG. The printed fabric 1 has a length corresponding to a plurality of feed pitch lengths (4P in the drawing).

  The automatic screen printing machine A is driven by a drive motor (servo motor) (not shown) and can be reversed between the drive roller 2 and the drive roller 2 horizontally. An endless belt 3 that intermittently rotates at a feed pitch and a screen printing unit 4 are provided, and the endless belt 3 is intermittently rotated at a required feed pitch P in the reverse direction by intermittent driving of the drive roller 2 in the reverse direction. It is like that.

  The screen printing unit 4 includes a screen frame 6 on which a screen 5 is stretched, and a squeegee (not shown) for printing the design of the screen 5 on the surface of the fabric 1 to be printed. The screen 5 is stretched around the screen frame 6. A plurality of types of screen frames 6 for performing multi-color printing are prepared.

  The printing sample preparation method includes a step of pressing the cloth to be printed 1 against the endless belt 3 by a non-illustrated pinching roller, and affixing the cloth 1 to the surface of the endless belt 3, a printing process, and a cloth to be printed 1 Cueing process.

In the textile printing process, the normal printing of the endless belt 3 causes the fabric to be printed 1 to be intermittently fed by a feed pitch P as shown in FIGS. 2 (a) to 2 (d), and screen printing while the endless belt 3 is stopped. Printing is performed by lowering the unit 4 and running the squeegee. Then, as shown in FIG. 2D, the trailing portion 1A in the moving direction of the fabric 1 to be printed when the endless belt 3 is rotated forward is sent to the lower position (printing position) of the screen printing unit 4 for printing. Thus, the first color printing is completed.
Thereafter, in the cueing step, the endless belt 3 is reversed to return the leading portion 1B in the moving direction of the fabric to be printed 1 when the endless belt 3 is rotated forward as shown in FIG. On the other hand, the screen frame 6 of the screen printing unit 4 is replaced with the screen frame 6 having the design of the second color material. In order to prevent the first color material and the second color material from being mixed, the second color printing is performed after ensuring the drying time of the color material. Thereafter, the same operation is repeated. In this way, by repeating the normal printing and cueing, the printing for one design in which multi-colored patterns are superimposed is completed, and then sent to the dryer.

FIG. 4 shows a control flowchart of the drive motor for operating the automatic screen printing machine. Of steps 41 to 47, the number of times of printing is set at step 42, and when the belt counter reaches the set number of times, the printing is terminated and the operation is switched to the belt return (reverse) operation.
Embodiment 2
The printing sample preparation method of this embodiment is to perform printing on the above-mentioned sample printing cloth 1 using the automatic screen printing machine A of FIG. 1, and the printing cloth 1 is made endless as described above. A step of attaching to the surface of the belt 3, a printing step by forward transfer, and a printing step by reverse feed after printing by the printing step by forward transfer are provided.

  The printing process by forward transfer is the same as the printing process described in the first embodiment, and the printing cloth 1 is intermittently sent to the printing position where the screen printing unit 4 is provided by the normal rotation of the endless belt 3. The trailing portion 1A in the direction of movement of the fabric to be printed 1 when the endless belt 3 is rotated forward is sent to the lower position (printing position) of the screen printing unit 4 for printing, whereby the first color printing is performed. finish.

  In the printing process by the reverse feed, the printing is performed while the fabric 1 is intermittently fed to the original printing position by the reverse rotation of the endless belt 3 as shown in FIG. That is, after the printing of the first color in the printing process by forward transfer is completed, the screen frame 6 of the screen printing unit 4 is replaced, so that the color material of the first color and the color material of the second color are not mixed. After securing the drying time, the fabric 1 to be printed is intermittently fed by the feed pitch length as shown in FIGS. 4A to 4D by the reverse rotation of the endless belt 3, and the endless belt 3 is stopped. Then, printing is performed by lowering the screen printing unit 4 and running the squeegee, and the leading portion 1B in the moving direction of the fabric to be printed 1 when the endless belt 3 is rotated forward is returned to the original position as shown in FIG.

  Then, the printing process by forward transfer and the printing process by reverse feed are alternately repeated, and the screen frame 6 of the screen printing unit 4 is replaced each time the printing by one printing process is completed. The printing for one stacked design is completed and then sent to the dryer.

FIG. 5 shows a control flowchart of the drive motor for operating the automatic screen printing machine. Of steps 51 to 62, the number of prints is set in step 53, and when the belt counter reaches the set number of times, the print is terminated and the operation is switched to the belt return (reverse) operation. The reason why the belt feed amount is increased in step 56 is that the feed amount is subtracted from the current position during reverse printing. In step 60, the counter is reversed until the current value of the counter becomes zero (the counter value of zero is the start position).
In the drawing, the screen printing unit is arranged only at the printing position of the printing sample. However, a plurality of screen printing units are arranged in the state of production, and only the screen printing unit at the printing position of the printing sample is used. You may create a printing sample.
