Description
Technical Field
The invention relates to a printed matter, a method of manufacturing the printed matter, an image forming apparatus, and a computer-readable storage medium.
Background
A method of printing a pattern of a metal color on a recording medium using an image forming apparatus such as an electrophotographic system or an inkjet system is being attempted. For example, attempts have been made to perform printing using a metallic color material such as gold in addition to pigments of 4 colors, i.e., cyan (C), magenta (M), yellow (Y), and black (K). However, even when a conventional metallic color material is used, a sufficient metallic luster cannot be obtained.
In order to realize a metallic luster in a simulated manner, attempts have been made to print using a transparent material having glossiness. The smoothness of the surface of the printed matter can be improved and the glossiness of the printed matter can be improved by using the transparent material having glossiness. For example, there is a proposal to calculate a CL value of a transparent material having CMYK values and glossiness by referring to RGB data of a target pixel and a color resolution LUT, and perform image printing in which a hue of diffused light and a hue of regular reflection light are matched.
However, in the conventional technique, the gloss can be improved by using a transparent material having gloss, but it is difficult to express a metallic texture.

Disclosure of Invention
The invention aims to provide a printed matter capable of simulating and expressing the texture of a metallic color, a manufacturing method of the printed matter, an image forming device and a method.
The present inventors have conducted intensive studies to solve the above problems. As a result, it was found that when a colored metallic luster is expressed in a pseudo manner using a transparent material having a luster, the chromatic chroma is insufficient. In addition, it has been determined that the lack of chroma is caused by the lack of specular reflection light by the colored color material layer after the excessive specular reflection light by the glossy transparent material layer. Further, in the layer of the transparent material having the gloss, by changing the amount per unit area obtained by dividing the amount of the material of the layer of the transparent material by the area of the layer of the transparent material, the specular reflection light of the layer of the colored material layer is enhanced while suppressing the excessive specular reflection light caused by the transparent material having the gloss, and the chroma is remarkably improved. Accordingly, the present inventors have conceived of one mode of the following invention.
One mode of the printed matter is characterized by comprising: a recording medium; a colored layer formed of a colored color material on the recording medium; a 1 st region which is present on the chromatic color layer and is a transparent material layer formed of a transparent material, and a 2 nd region which is present on the chromatic color layer and is a transparent material layer formed of the transparent material, an amount of a 1 st unit area obtained by dividing an amount of the transparent material forming the 1 st region by an area of the 1 st region and an amount of a 2 nd unit area obtained by dividing an amount of the transparent material forming the 2 nd region by an area of the 2 nd region are different.
According to the present invention, the texture of metallic color can be expressed in a simulated manner.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. In addition, in the following, as an example of the transparent material having glossiness, a color toner is exemplified as a transparent toner as a color material, but the present invention is not limited to the toner, and is also applicable to a case where ink or the like is used, for example.
(embodiment 1)
First, embodiment 1 will be explained. Embodiment 1 relates to a printed matter. Fig. 1A is a schematic plan view showing the structure of a printed matter according to embodiment 1, and fig. 1B is a schematic cross-sectional view taken along line I-I in fig. 1A.
The printed matter 100 according to embodiment 1 includes a recording medium 110, a colored toner layer 120 on the recording medium 110, and a transparent toner layer 130 on the colored toner layer 120. The colored toner layer 120 includes a 1 st colored region 121 and a 2 nd colored region 122. For example, the 1 st colored region 121 and the 2 nd colored region 122 are alternately arranged. In the present embodiment, the 2 nd colored region 122 has a higher saturation S2 than the 1 st colored region 121 has a higher saturation S1. The transparent toner layer 130 (transparent material layer), which is a layer formed of a transparent material, includes a 1 st region 131 overlapping with the 1 st colored region 121 in plan view and a 2 nd region 132 overlapping with the 2 nd colored region 122 in plan view. In the present embodiment, the amount t2 of the 2 nd unit area obtained by dividing the amount of the transparent toner of the 2 nd region 132 by the area of the 2 nd region 132 is smaller than the amount t1 of the 1 st unit area obtained by dividing the amount of the transparent toner of the 1 st region 131 by the area of the 1 st region 131. Preferably, the amount t2 of the transparent toner of the 2 nd unit area in the 2 nd region 132 is 0. The recording medium 110 is high-quality paper, glossy coated paper, matte coated paper, OHP, plastic film, or the like.
The chromatic color toner layer 120 includes cyan (C), magenta (M), yellow (Y), or any combination thereof, and may further include black (K) toner. The transparent toner layer 130 is formed using a transparent toner, and the transparent toner is generally a colorless and transparent toner containing no color material such as a pigment, but the transparent toner does not need to be completely colorless and transparent as long as the total light transmittance is 30% or more. The transparent toner may contain a color if the total light transmittance is 30% or more. The total light transmittance is a transmittance measured by irradiating a sample obtained by modulating a toner with visible light emitted from a halogen lamp as a light source according to the total light transmittance test method of jis k7361-1 and ISO 13468-1.
Here, the operation of printed matter 100 according to embodiment 1 will be described. Fig. 2 is a schematic diagram illustrating an operation of printed matter 100 according to embodiment 1. When the light 10 is irradiated onto the printed matter 100, a part of the light 10 is reflected by the 1 st area 131, another part is reflected by the 1 st colored area 121, and another part is reflected by the 2 nd colored area 122. In the present embodiment, since the amount t2 of the transparent toner per unit area 2 in the 2 nd region 132 is 0, reflection does not occur in the 2 nd region 132. Therefore, most of the light incident to the 1 st region 131 is reflected by the 1 st region 131 and the 1 st colored region 121, although depending on the incident angle. The specularly reflected light 21 of the 1 st colored region 121 includes the colored color of the 1 st colored region 121, and the specularly reflected light 31 emitted from the 1 st region 131 has the same brightness as the light 10. Therefore, the colored normally reflected light including the 1 st colored region 121 can be obtained with high gloss. On the other hand, the light incident on the 2 nd region 132 is not reflected by the 2 nd region 132, and most of it is reflected by the 2 nd colored region 122, although depending on the incident angle. The specular reflection light 22 of the 2 nd colored region 122 includes the colored color of the 2 nd colored region 122, and in the present embodiment, the saturation S2 of the 2 nd colored region 122 is higher than the saturation S1 of the 1 st colored region 121. Therefore, colored normal reflected light with high chroma including the 2 nd colored region 122 can be obtained.
In the present embodiment, the 1 st colored region 121 and the 2 nd colored region 122 are adjacent to each other, and the 1 st region 131 and the 2 nd region 132 are also adjacent to each other in a manner imitating that the 1 st colored region 121 and the 2 nd colored region 122. Therefore, in human vision, it is perceived that the specular reflection light 40 of the printed matter 100 has both high gloss and high chroma.
Such an action of the printed matter 100 can provide high glossiness and high chroma, and thus can simulate a metallic texture well.
In addition, in the present embodiment, although the 2 nd region 132 is a region where the amount t2 of the 2 nd unit area of the transparent toner is 0, if the amount t2 of the transparent toner of the 2 nd unit area of the 2 nd region 132 is less than the amount t1 of the transparent toner of the 1 st unit area of the 1 st region 131, the amount t2 of the 2 nd unit area of the transparent toner in the 2 nd region 132 may not be 0. For example, the 2 nd region 132 may have an amount of the transparent toner per unit area of 10% or less of the 1 st region 131. Even if the amount t2 of the 2 nd unit area of the transparent toner in the 2 nd region 132 is not 0, since the reflection of the 2 nd region 132 is lower than the reflection of the 1 st region 131 and the reflection of the 2 nd colored region 122 is larger than the reflection of the 1 st colored region 121, a high chroma can be obtained.
In the present embodiment, the saturation S2 of the 2 nd colored region 122 is higher than the saturation S1 of the 1 st colored region 121, but they may be equal to each other. Even if they are equal, since the 2 nd colored region 122 has a stronger reflection than the 1 st colored region 121, a high chroma can be obtained.
The 1 st region 131 and the 2 nd region 132 are arranged at a certain period. This is because the color unevenness is hard to be perceived by human vision.
The area of the 1 st region 131 is preferably larger than that of the 2 nd region 132. This is to improve the gloss which is one of the characteristics of metallic gloss. The area ratio of the 1 st region 131 to the 2 nd region 132 is not particularly limited, and is, for example, 2: 1. The area ratio may be 3:1, 3:2, 1:1, or the like.
The resolution of the printed matter 100 is not particularly limited, but is preferably 300dpi or more, more preferably 600dpi or more. This is to make it visually difficult to distinguish the specularly reflected light from the respective areas.
(embodiment 2)
Next, embodiment 2 will be explained. Embodiment 2 relates to a method for producing a printed matter. Fig. 3 is a schematic diagram showing an outline of a printed matter manufactured according to embodiment 2. Fig. 4 is a flowchart showing a method for manufacturing a printed matter according to embodiment 2. Fig. 5A to 5B are schematic views showing the process sequence of the method for producing a printed matter according to embodiment 2.
As shown in fig. 3, the printed matter manufactured according to embodiment 2 is a prize 200, and prize 200 includes a character area 210 and a peripheral edge portion 220. The edge portion 220 is provided with a decorative pattern such as a golden color of an animal or plant. Here, as an example, a printed matter is manufactured at a resolution of 600 dpi. In fig. 5A to 5F, as an example of a part of the printed matter, a range of a rectangle included in the pattern of the edge portion 220 is shown.
In embodiment 2, first, as shown in fig. 5A, the range and the color of the metallic lustrous region expressing the chromatic metallic lustrous are determined on the recording medium 250 (step S210). For example, the range 251 of the decorative pattern is determined, and the gold color is specified as its color. For example, "C: 0%, M: 12%, Y: 57%, K: 6%, CL: 100%" is set when a gold pattern is drawn. Here, "CL" is a transparent gray value.
Next, print data is created (step S220).
In the creation of print data, Y is first selected from the chromatic color components (C, M and Y) constituting the gold color (step S221). Although a colored component other than Y may be selected, Y which is the closest gloss color to gold among C, M and Y is preferably selected. Since K is achromatic, it is out of the selection object. As shown in fig. 5B, the pattern 260 of Y coincides with the range 251.
Next, the pattern 260 of Y is 2-valued (step S222). Here, as shown in fig. 5C, assuming that the area ratio of the portion 261 having a gray scale value of Y of 0% to the portion 262 having a gray scale value of Y of 100% is 2:1, the gray scale value of Y is temporarily changed to 33%, and then 2-valued processing is performed to create a 2-valued pattern 263 of Y. The 0% gray scale value of Y is an example of the 1 st value, and the 100% gray scale value of Y is an example of the 2 nd value. The area ratio of portion 261 to portion 262 may be 3:1, 3:2, or 1:1, etc.
Next, as shown in fig. 5D, the gradation value of the portion 272 overlapping with the gradation value portion 262 of CL is changed from 100% to 0%, and the gradation value of the portion 271 overlapping with the gradation value portion 261 of CL is maintained at 100%. Thus, data for the transparent toner layer is created in which the transparent gradation value is set to 100% in the portion 271 overlapping with the portion 261 and to 0% in the portion 272 overlapping with the portion 262 (step S223).
Next, as shown in fig. 5E, the gradation value of Y of the portion 261 is changed from 0% to 36%. This is because the average value of the gradation values of Y in the entire metallic luster region is made to approach the gradation value before 2-valued gradation value, while using 2/3 of the color toner layer 120 as the 1 st colored region 121, 1/3 as the 2 nd colored region 122, and the gradation value of Y in the 2 nd colored region 122 as 100% in plan view. That is, after the 2-valued gradation value is changed to 33% as the average value of the gradation value of Y in the entire metallic luster area, the average value of the gradation value of Y can be changed to about 57% by changing the gradation value to 36%. In this way, data for the chromatic toner layer is created in which the average value of the gradation values in the entire metallic lustrous region of Y is changed to a gradation value close to the gradation value before 2-valued gradation value (step S224). If the average value is simply made to approach the gradation value before 2-valued, the gradation value of the part 262 may be changed without changing the gradation value of the part 261, or both the gradation values of the part 261 and the part 262 may be changed. However, in order to obtain a high chroma and to make the average value approach the gradation value before 2-valued gradation value, it is preferable to temporarily change the gradation value of only the portion 261 to 0%.
Thus, print data is created (step S220). In addition, for the colors (C, M, and K) other than Y selected in step S221, the gradation values determined in step S220 are used as they are. Therefore, in the print data, the 1 st colored region 121 has gradation values of "C: 0%, M: 12%, Y: 36%, and K: 6%", and the 2 nd colored region 122 has gradation values of "C: 0%, M: 12%, Y: 100%, and K: 6%". The gradation value of the 1 st region 131 is "CL: 100%", and the gradation value of the 2 nd region 132 is "CL: 0%".
After the print data is generated, a color toner layer is formed on the recording medium 250 based on the print data using the image forming apparatus (step S231), and a transparent toner layer is formed on the color toner layer (step S232). As a result, as shown in fig. 5F, a pattern 283 including a region 281 in which the 1 st colored region 121 and the 1 st region 131 overlap and a region 282 in which the 2 nd colored region 122 and the 2 nd region 132 overlap is printed on the recording medium 250 (step S230).
Thus, a printed matter can be produced. Also, the pattern 283 formed on the recording medium 250 can simulatively express a gold metallic luster.
The 2-valued pattern is not limited to a pattern in which 2 kinds of regions are arranged in 1 direction, and may be a pattern in which 2 kinds of regions are arranged in 2 directions orthogonal to each other. That is, the 2-valued pattern may be a lattice pattern.
(embodiment 3)
Next, embodiment 3 will be explained. Embodiment 3 relates to an image forming apparatus suitable for carrying out the method for manufacturing a printed matter according to embodiment 2. Fig. 6 is a block diagram showing a hardware configuration of the image forming apparatus according to embodiment 3.
The image forming apparatus 300 according to embodiment 3 includes, for example, a cpu (central processing unit)301, a ram (random access memory)302, a rom (read only memory)303, a storage unit 304, a network I/F305, an operation unit 306, a scanner 307, a printer 308, an image memory 309, a wireless communication device 310, and a bus 311.
The CPU301 is a computing device that realizes each function of the image forming apparatus 300 by reading programs and data stored in the ROM303, the storage unit 304, and the like onto the RAM302 and executing the processing. The RAM302 is a volatile memory used as a work area of the CPU 301. The ROM303 is a nonvolatile memory that can hold programs and data even when power is turned off.
The storage unit 304 is a large-capacity storage device such as an hdd (hard disk drive), an ssd (solid state drive), and the like, and stores an os (operation system), application programs, various data, and the like. The network I/F305 is a communication interface for connecting the image forming apparatus 300 to a network. The operation unit 306 is a display input unit such as a touch panel serving as both an input device for receiving an input operation by a user and a display device such as a Liquid Crystal Display (LCD).
The scanner 307 is a reading device that reads an image from an original and converts it into image data. The printer 308 is a printing device that prints image data. The image memory 309 is a memory used as a work area in image processing such as image reading, printing, and copying.
The wireless communication device 310 is a communication device that communicates with a computer, a mobile phone, or the like through wireless communication such as wireless lan (locaiareanetwork), wireless pan (personaiareanetwork), infrared communication, or acoustic communication. The bus 311 is connected to the above-described components, and transmits address signals, data signals, various control signals, and the like.
Next, a functional configuration of the image forming apparatus 300 will be described. As described above, the CPU301 realizes the functions of the image forming apparatus 300 by reading out programs and data stored in the ROM303, the storage unit 304, and the like onto the RAM302 and executing the processing. Fig. 7 is a functional block diagram of an image forming apparatus 300 according to embodiment 3. As shown in fig. 7, the image forming apparatus 300 includes an acquisition unit 351, a print data generation unit 352, and a printing unit 353.
The acquisition unit 351 acquires input data for displaying the range and the color of the metallic luster area in which the metallic luster of the color is expressed on the recording medium. The input data may be retrieved through the network I/F or the communication device 310. The image forming apparatus 300 may be provided with a slot for an external computer-readable storage medium, and input data may be acquired from the external computer-readable storage medium such as an IC card, a flexible disk, a CD, a DVD, an SD memory card, or a USB memory. The print data generation unit 352 generates print data using the image memory 309 or the like in step S220. The printing unit 353 performs printing using the printer 308 or the like in accordance with step S230.
After the input data acquired by the acquisition unit 351 is prepared, the image forming apparatus 300 performs the same processing as the method of manufacturing a printed matter according to embodiment 2, and can manufacture a printed matter that artificially expresses the texture of a metallic color.
In addition, the color of the metallic lustrous region is not limited to gold, but may be copper, bronze, or the like. For example, since the bronze color is reddish, when the texture of the bronze color is expressed in a simulated manner, the ratio of the magenta color in the primary color is increased, and the chromatic color component to be subjected to the quantization of 2 of the gradation value is defined as the magenta color. Further, depending on the color to be expressed, the chromatic color component to be a 2-valued gradation value may be changed to 2 or more.
The transparent toner layer may include a region having a different amount of transparent toner per unit area of 3 or more, and the chromatic color toner layer may include a region having a different chroma of 3 or more. In this case, the amount of the transparent toner per unit area in the transparent toner layer is preferably smaller as the region overlapping with the region having the high chroma of the color toner layer is larger, and the region overlapping with the region having the highest chroma is preferably a region having an amount of the transparent toner per unit area of 0, as in embodiment 1. The amount of the transparent toner per unit area in this case is obtained by dividing the area of the corresponding region by the amount of the transparent toner in the region.
In addition, although in these embodiments, a transparent toner is used as the transparent material having glossiness and a color toner is used as the color material, in the present invention, the color material is not limited to the toner. For example, in the present invention, a color material such as ink may be used.
