Description

PVC Flooring {PVC FLOOR SHEET}

The present invention relates to a PVC flooring, and more particularly, by performing color simulation in the flooring manufacturing process to derive a desired color, cost reduction and the process is simplified by eliminating the color production process and roll production that incurs costs. The present invention relates to a manufacturing method of PVC flooring material which can improve the quality of design by economical and new color development.

In general, in the production process of PVC flooring and industrial sheet products, a gravure printing method in which ink is formed in ink pockets formed on the concave plates and transferred to a printing object is applied.

In addition, the manufacturing method of the flooring is generally divided into a prototype manufacturing process and a finished product process. 1 briefly illustrates a manufacturing process of the conventional flooring.

As shown in Figure 1, the prototype manufacturing process (st70) is a design process (st10), artwork evaluation process (st20), roll production process (st30), gravure printing process (st40), foaming process (st50), and Color matching process (st60).

In addition, the finished product manufacturing process in Figure 1 is made of a gravure printing process and a foaming process using a printing roll produced during the prototype, after which it is released to the market through the finished product evaluation process (st80).

In the production of the prototype, the roll production process st30 includes a separation plate st31, a print roll production st32, and an embossing roll production st33 operation.

In the gravure printing process (st40), the selected color is printed after the artwork evaluation.

The foaming process st50 includes a skin layer work st51, a foaming work st52 and an embossing work st53 of the artwork printed by the gravure printing process st40.

The color matching process (st60, st61) is a process of reviewing the product after the foaming process (st50), selecting an appropriate color, and adjusting the color by the color tone maker (st62).

In the finished product review process (st80), a review for a new color of the finished product completed by the above process is in progress. The finished product that has passed the finished product review process st80 is produced as a sample book and distributed to the market. Finished products determined to be insufficient in the finished product review process (st80) are discarded and the design process (st10) is resumed.

However, this method does not apply to the finished product when insufficient decision is made after the prototype evaluation. Therefore, the production roll has to be discarded and the fabric used in the color matching during the manufacturing of the prototype must be discarded. . In addition, the need to manufacture a prototype again causes a reduction in work efficiency and waste of time and money due to insufficient product quality.

As a result, the conventional flooring manufacturing method generates unnecessary costs due to the loss of production opportunities for new colors, and delays time to market of products when a lot of insufficient colors are generated.

In order to solve the problems of the prior art as described above, an object of the present invention is to perform a color simulation during the flooring manufacturing process, it is possible to omit the cost of roll production and color matching and to develop a new color process, time and cost In addition to significantly reducing the cost, the company also provides PVC flooring to improve the design and color quality.

Hereinafter, the present invention will be described in more detail with reference to Examples. However, the following examples are merely to illustrate the subject innovation and the scope of the subject innovation is not limited to the following examples.

Example 1

All the possible variables for prototyping paper artwork were derived from Table 1 below.

Possible variables Artwork Finished The gap between artwork and finished product Prototype Possibility fabric paper PVC Whiteness, surface tension ○ Separation - 5 degree separation Contrast ○ ink Jet print ink Gravure ink Color development, transparency × Print method Plateless printing Intaglio printing resolution × Foaming Process No foam In foam Sharpness, delicateness △ Skin presence No emboss With emboss Transparency, gloss △ Embossing Process No skin With skin Texture, reality △

As shown in Table 1, when the fabric of the artwork is paper and the fabric of the finished product is PVC, the artwork and the finished product have a gap in whiteness and surface tension, and the gap allows the paper fabric to be used as a prototype.

If the artwork is with or without separation and the finished product is a 5 degree separation, the artwork and finished product have a gap in sharpness, which allows the application of the separation to the prototype.

However, when the ink of the artwork is jet print ink and the finished ink is gravure ink, the artwork and the finished product have a gap in color development and transparency, which makes the jet print ink inapplicable to the prototype.

If the artwork is printed on plateless printing and the finished product is intaglio printing, the artwork and finished product have gaps in resolution, and this gap prevents the application of plateless printing to the prototype.

If the artwork does not go through the foaming process and the finished product goes through the foaming process, the artwork and the finished product have a gap in clarity and detail, which makes the foam less likely to be applied to the prototype.

If the artwork does not go through the embossing process and the finished product goes through the embossing process, the artwork and finished product have gaps in transparency and gloss, and this gap lowers the possibility of applying the embossing process to the prototype.

If the artwork does not go through the skin layer process and the finished product goes through the skin layer process, there is a gap in texture and realism, and this gap lowers the possibility of applying the skin layer process to the prototype.

Example 2

An experiment was performed to determine a printing method having the same effect as the gravure printing method from the possible variables as in Example 1.

A schematic diagram of the printing method for determining the printing method is shown in FIG. 4. In FIG. 4, the plateless printing method is an inkjet method for delivering ink by an electric signal, and the flat printing method is an offset printing method using chemical repellency of lipophilic and hydrophilicity, and the stencil printing method punctures the film of the non-wire portion to make ink. It is a silk screen method of delivering, and the top plate printing method is a gravure method that transfers ink directly to the embossed ink.

The comparison results for the printing method are shown in Table 2 below, and the numerical values of the respective items are relative values, and the printing effect means a level compared with the gravure printing effect.

Monolium Fabric Application Print size Printing effect Lead time cost (a) Non-printing (inkjet) △ 5 4 5 5 (b) off-set printing ○ 2 4 3 2 (c) stencil printing (silk screen) ○ 2 3 2 2 (d) Copper plate printing (gravure printing) ○ 5 5 2 2

In Table 2, it can be seen that in comparison of the four printing methods, the live inkjet method, which is a plateless printing method, is an optimal printing method having an excellent printing effect compared to other printing methods.

Example 3

The present invention was carried out the following test in order to derive the ink that does not discolor in the subsequent step of the foaming process.

The test was carried out with the first test with an idea, the second test by coating and printing on the PVC fabric, and the third test with ink that can be printed directly on the PVC fabric.

In the first test, an oily pigment was used to test the PVC fabric on the real-time output machine. As a result, spreading occurred when printing on the PVC fabric, and printing was possible only on dedicated paper.

The second test was a coating test after coating the PVC fabric with an oily pigment, and as a result, coating equipment size was limited, and coating deformation occurred due to heat after the foaming process.

The third test was carried out with a testable ink coated on a PVC fabric, the results are shown in Table 3 below.

Ink type Monolium Fabric Printing Effervescent Economics Aqueous dyes × × × UV curing ○ ○ × Water-based pigment × × × Disperse Pigments × × × Torch Dispersion × ○ × Solvent ○ ○ ○

In Table 3, the aqueous dye ink is not suitable for PVC fabric printing, foamability and economics, the UV curable ink is suitable for PVC fabric printing and foaming, and is unsuitable in economics, and the aqueous pigment and disperse dye ink are PVC fabric printing, foamability And not economically suitable, the toner dispersion ink is unsuitable for PVC fabric printing and economics and suitable for foaming, and the solvent ink is suitable for both PVC fabric printing, foaming and economics.

As a result of the 1st, 2nd, 3rd test, it can be seen that the solvent ink, which can be printed on the PVC fabric and has no deformation (5) in the foaming process, is the optimal ink.

Example 4

In comparison with the difference in the pattern clarity of the prototype and the finished product produced by the method of the present invention is shown in Table 4 below.

Color similarity Color clarity Delicate pattern Color, vividness of the pattern Rating 1 ◎ ◎ ◎ ○ Evaluation 2 ◎ ◎ ○ ○ Evaluation 3 ○ ◎ ○ ○ Evaluation 4 ◎ ○ ○ ○ Evaluation 5 ◎ ◎ ○ ◎ Evaluation 6 ◎ ◎ △ ◎

week)

◎: same level (100%: non-visual classification)

○: similarity level (90% ~ 99%: slight difference)

△: Normal level (80% ~ 89%: Visual classification possible)

×: insufficient level (less than 80%: difference is obvious)

In Table 4, the prototype using the printing method and the ink of the present invention is almost similar to the finished product, and it can be seen that a slight gap exists only in the sharpness of the pattern. That is, in the comparison between the prototype and the finished product, it can be seen that the similarity of color, the sharpness of the color, the delicate pattern expression, and the color and the sharpness of the pattern are the same level or the similar level.

Example 5

In the present invention, the resolution and the printing method were determined through a color simulation process (ST40), as shown in FIG. 5, in order to reduce the gap between the pattern sharpness of the prototype and the finished product.

The present invention reproduces the effect of clarity by connecting the spot color separation system of the Barco system rather than the primary color separation method used in the first inkjet printer. Spot color separations are inkjet print control software.

The present inventors found that the resolution of 720 × 720 is the most similar to the finished product by adjusting the resolution.

In addition, by adjusting the printing method, it is possible to change the general bidirectional printing style from unidirectional printing to increase the fineness of printing.
