Description

{METHOD FOR PRINTING KOREAN PAPER}

The present invention relates to a paper printing method capable of easily printing a paper sheet having a step on a surface by a UV printing method and having a high ink absorption rate.

As is well known, with respect to a printing medium (for example, paper, snow paper, art paper, etc.) placed on a seating table called a platen, Such as an ink-jet printer, which prints on a print medium by ejecting ink from a recording medium.

Such a printing apparatus ejects an ultraviolet curable ink (i.e., UV ink) having a property of curing upon irradiation with ultraviolet light from a print head and prints on a print medium. Since the UV ink has excellent weather resistance and water resistance, It can be used for outdoor advertisement front end and the like, and the use of printed matter is greatly expanded as compared with the case of using water-soluble ink.

In the printing apparatus for discharging and printing UV ink, there is provided an ultraviolet ray irradiating device for irradiating ultraviolet rays to the UV ink adhered to the printing medium to cure the ultraviolet ray irradiating device. The ultraviolet ray emitting diode That is, a printing device using a UV LED) has been developed.

Such a printing apparatus may include a pair of UV irradiators arranged on the left and right sides of the print head, the UV irradiators being configured to emit ultraviolet rays toward a printing medium positioned below the UV LED.

The print head includes a magenta print head for ejecting magenta UV ink toward a print medium from a plurality of nozzles provided on a lower surface thereof, a yellow print head for ejecting yellow UV ink, a cyan print head for ejecting cyan UV ink, And a black print head for ejecting the black print head.

Further, when printing on a print line of a print medium, UV ink is ejected from each nozzle of the print head while reciprocating the print head leftward and rightward a predetermined number of passes above the print line, and is superimposed on the print line in a desired pattern .

At this time, an ultraviolet ray of an irradiation intensity capable of completely curing the UV ink is emitted from the ultraviolet ray irradiating apparatus, and the ultraviolet ray is irradiated to the printing line so that the UV ink adhered to the printing line can be printed have.

On the other hand, Hanji has excellent preservation of archives as well as a unique texture compared to ordinary paper, as it can be seen from the preservation of archives in eastern and western regions, and gives a feeling of luxury and warmness.

However, in the case of Korean paper, since ink absorption is excellent, when ink is printed in the same manner as ordinary printing paper (for example, snow paper, art paper, etc.), there is a problem that the ink is absorbed, There is a problem that the print head is damaged when the print head and the surface of the paper are brought into contact with each other because the step height is higher than that of general print paper (for example, snow paper, art paper, etc.).

It is difficult to print image data (e.g., photographed images, etc.) on Korean paper due to the above-described problems.

Advantages and features of embodiments of the present invention and methods of achieving them will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The following terms are defined in consideration of the functions in the embodiments of the present invention, which may vary depending on the intention of the user, the intention or the custom of the operator. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a process of printing a Korean paper according to an exemplary embodiment of the present invention.

Referring to FIG. 1, a paper sheet may be placed on a seat of a printing apparatus (step 102). Herein, Korean paper having various steps (for example, 1.5 mm, 2 mm, 2.5 mm, etc.) can be used.

Then, it can be fixed in accordance with the printing range of the paper sheet placed on the mounting table (step 104). Here, a single-sided tape or double-sided tape may be attached and fixed to a rim portion corresponding to the printing range of Korean paper (e.g., a portion corresponding to the size of the image data to be printed), and the rim portion A single-sided tape or double-sided tape may be attached to the outer portion, or a single-sided tape or double-sided tape may be attached to only a part of each of the rectangular sides.

In addition, water can be sprayed on the surface of the paper sheet placed on the mounting table (step 106). In this case, water can be sprayed evenly on the entire surface by using a water sprayer, and water can be sprayed so that the water content of the paper can be approximately 3-8%, and the entire surface of the paper can be used Or only a part of the surface having relatively high steps can be squeezed by using the pressing roller.

Here, when water is sprayed to contain less than 3% water, the ink does not bleed during printing but it is difficult to reduce the level difference through the pressing process, and when the moisture content exceeds 8%, the pressing process is easy However, ink containing too much moisture may easily occur when printing.

Next, the distance between the surface of the paper and the nozzle provided in the print head may be set to be firstly spaced apart by the first interval (step 108). Here, the first distance may be set to 1.2 to 1.8 mm, and the distance between the surface of the paper and the nozzle provided in the print head may be measured through the distance measuring sensor, and the distance may be spaced by the first distance Can be set using an interval setting key provided in the printing apparatus.

Then, according to the primary setting, printing of the image data transmitted to the printing apparatus can be started (step 110). Such a printing operation is carried out using a UV ink and a UV lamp. The UV ink is sprayed onto the surface of the paper through the nozzles of the print head, and the printing can be performed by curing using UV lamp within at least 0.3 second. This makes it possible to print clearly so that the ink does not spread on a paper sheet having a high ink absorption rate.

Further, during the printing, the interval between the surface of the paper and the nozzle of the print head may be set to be secondarily set (step 112). Here, the second gap may be set to maintain 1.2-1.5 mm.

Then, the printing can be completed while performing the secondary setting step as described above at least once (step 114). Here, since the surface of the Korean paper has a higher step than that of a general printing paper even when water is sprayed on the paper, it is necessary to press the paper at least once (that is, once Or more).

Therefore, in the present invention, the distance between the surface of the paper and the nozzle of the print head is set so as to be spaced apart by the first distance, and the distance between the surface of the paper and the nozzle of the print head is maintained It is possible to easily print on a sheet of paper having a higher step height than normal printing paper without damaging the print head.

In addition, the present invention provides a method of printing using a UV lamp and a UV lamp, wherein UV ink is jetted from the print head while maintaining a gap between the surface of the paper and the nozzles of the print head by a second distance, By curing, the ink can be printed so that the ink does not spread on a paper sheet having a high ink absorption rate.

2 is a flowchart illustrating a process of printing a Korean paper according to another embodiment of the present invention.

Referring to Fig. 2, the paper can be seated on the seat of the printing apparatus (step 202). Herein, Korean paper having various steps (for example, 1.5 mm, 2 mm, 2.5 mm, etc.) can be used.

Then, it can be fixed in accordance with the printing range of the paper sheet placed on the mounting table (step 204). Here, a single-sided tape or double-sided tape may be attached and fixed to a rim portion corresponding to the printing range of Korean paper (e.g., a portion corresponding to the size of the image data to be printed), and the rim portion A single-sided tape or double-sided tape may be attached to the outer portion, or a single-sided tape or double-sided tape may be attached to only a part of each of the rectangular sides.

In addition, water can be sprayed on the surface of the paper sheet placed on the mounting table (step 206). In this case, water can be sprayed evenly on the entire surface by using a water sprayer, and water can be sprayed so that the water content of the paper can be approximately 3-8%, and the entire surface of the paper can be used Or only a part of the surface having relatively high steps can be squeezed by using the pressing roller.

Here, when water is sprayed to contain less than 3% water, the ink does not bleed during printing but it is difficult to reduce the level difference through the pressing process, and when the moisture content exceeds 8%, the pressing process is easy However, ink containing too much moisture may easily occur when printing.

Next, the interval between the surface of the paper and the nozzle provided in the print head may be set to be firstly spaced by the first interval (step 208). Here, the first distance may be set to 1.2 to 1.8 mm, and the distance between the surface of the paper and the nozzle provided in the print head may be measured through the distance measuring sensor, and the distance may be spaced by the first distance Can be set using an interval setting key provided in the printing apparatus.

Then, according to the primary setting, primary printing of the image data transmitted to the printing apparatus using the first density UV ink can be started (step 210). This printing operation is carried out using UV inks and UV lamps, and the first density can be set at a ratio of approximately 20-60% when a typical printing density is 100%, whereby the first printing of image data Can proceed.

Here, the printing operation can be performed in such a manner that UV ink is sprayed onto the surface of the paper through a nozzle of the print head and then cured by using a UV lamp within at least 0.3 seconds. Thus, So that it can be printed clearly.

Further, during the primary printing, the interval between the surface of the paper and the nozzle of the print head may be set to be secondarily set (Step 212). Here, the second gap may be set to maintain 1.2-1.5 mm.

Then, the primary printing can be completed while performing the secondary setting step as described above at least once (step 214). In this case, since the surface of the Korean paper has a higher level difference than that of a general printing paper even when water is sprayed on the surface of the paper, the paper can be pressed at least once (i.e., One or more times).

Next, secondary printing may be started at a second density for the image data transferred to the printing device (step 216). Here, the second concentration can be set at a ratio of approximately 40-80% when the general printing density is 100%, and the UV ink is cured by using a UV lamp within at least 0.3 seconds after jetting the UV ink onto the surface of Korean paper Printing process is performed. Therefore, no separate drying process is required after the first printing is completed, so that the image data can be printed more easily and clearly on the paper.

In another embodiment of the present invention as described above, the first density is 20-60% and the second density is 40-80%. However, the first density is 40-80% The second density can be 20 to 60%, and second printing can be performed. It is needless to say that printing can be performed at least twice at a relatively low concentration compared with a general ink concentration in order to prevent ink bleeding.

Then, during the secondary printing, the interval between the surface of the paper and the nozzle of the print head can be reset so as to maintain the second gap (step 218). Here, the second gap may be set to maintain 1.2-1.5 mm.

Then, the secondary printing can be completed while performing the resetting step as described above at least once (step 220). In this case, since the surface of the Korean paper has a higher step than that of the conventional printing paper even when water is sprayed on the surface of the paper, the paper can be pressed at least once (i.e., One or more times).

Therefore, according to the present invention, it is possible to print more clearly so that the ink does not spread on a paper sheet having a high ink absorption rate, by first printing the image data to the first density and secondly printing the image data to the second density .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be readily apparent that such substitutions, modifications, and alterations are possible.
