Description

  The present invention relates to a technique for improving the visibility of a solid-printed color on the ground color in a packing material on which a color similar to the ground color of a printing surface is solid-printed.

  For the purpose of assisting the user's understanding of the product, it is widely performed to print a display related to the appearance and characteristics of the product on the surface of the packing material for packing the product. At that time, a color relating to the product, for example, a toner color in the case of a toner container is printed on the packing material as the display. Here, the display color may not be recognized as the original color in relation to the background color of the packaging material on which the printing is performed. Although it is a method for manufacturing ceramic building boards rather than packing materials, Patent Document 1 discloses a method for manufacturing decorative building boards having a full-color printed layer by an inkjet method on the design surface of ceramic building boards. There is disclosed a technique in which a background color having the same or approximate hue as the hue most frequently used in a color pattern to be used is colored on the design surface, and then a full color printing layer is formed on the design surface.

According to the method of Patent Document 1, the density of ink dots is reduced in a light color portion of full-color printing, and a background color is exposed between ink dots, which is different from the hue of full-color printing originally intended to be developed. Can be prevented.

  However, in the method of Patent Document 1, for example, when the packaging material is brown cardboard and the display color is yellow, when the ground color of the packaging material is similar to the color to be printed, the essential color Is not conspicuous, and the purpose of helping the user to understand the product by visually recognizing the color of the product cannot be sufficiently achieved.

  The present invention has been made in view of such a conventional problem, and even when the ground color of the packaging material and the print color printed on the surface of the packaging material approximate, the print color is determined from the ground color. An object is to provide a packaging material that can be clearly distinguished and visually recognized.

  A packing material according to claim 1 of the present invention includes a packing unit that accommodates an article and a display unit that is printed on a surface of the packing unit, and the display unit has a color on the ground color of the surface of the packing unit. A color display unit for visual recognition, wherein the color display unit is a first layer solid-printed with a first color having a small hue difference and / or lightness difference with respect to the ground color; and the first color And a second layer that is dot-printed on the first layer with a second color of lower brightness.

  According to the first aspect of the present invention, on the first layer solid-printed with the first color, the second layer dot-printed with the second color having a lightness lower than that of the first color is provided. The formed color display portion can be formed, and the visibility of the first color is improved by the presence of a halftone dot composed of the second color. Therefore, even if the first color is solid-printed on the ground color that approximates the first color, the first color is not buried in the ground color and is recognized as that color. There is an effect.

  In the packing material according to claim 2 of the present invention, the packing portion is made of cardboard. According to the invention which concerns on Claim 2, the said display part can be formed in the surface of the cardboard used frequently as a raw material of a packaging material.

  The packaging material according to claim 3 of the present invention is such that in the packaging material of claim 2, the cardboard is brown cardboard, the first color is yellow, and the second color is green. According to the invention which concerns on Claim 3, the yellow solid printing printed on the brown corrugated cardboard which is a general corrugated cardboard is visually distinguished and distinguished clearly from brown which is a ground color.

  The packaging material according to claim 4 of the present invention is the packaging material according to claim 2, wherein the cardboard is brown cardboard, the first color is gray, and the second color is black. According to the invention which concerns on Claim 3, the solid solid printing of the gray printed on the brown corrugated cardboard which is a general corrugated cardboard is visually distinguished from the brown which is a ground color clearly.

  The packaging material according to claim 5 of the present invention is a packaging material according to claim 3, in which a toner container containing yellow toner is packaged as the article. According to the fifth aspect of the invention, the user can intuitively grasp the color of the toner enclosed in the toner container.

  Here, by displaying the color of the encapsulated toner on the packaging material of the toner container, the user can intuitively grasp the toner color of the packaged toner container. However, if such a color display part is buried in the ground color of the packaging material and is difficult to visually identify, it is impossible to provide convenience to the user. However, according to the invention of claim 5, the toner color yellow is solidly printed as a display on the packing material in a state of being clearly distinguished from the ground color brown, and is packed. It is possible to provide a user-friendly packaging material in which the toner color of the toner container can be grasped at a glance.

  According to the packaging material of the present invention, regardless of the ground color of the packaging material, the color relating to the article packed in the packaging material can be clearly distinguished from the ground color of the packaging material and visually recognized. As a result, it becomes easy for the user to obtain an understanding regarding the packed article.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an example of a packaging material according to the present invention. In this example, the packing material 1 is a brown cardboard box formed in a substantially rectangular shape and is used for packing a toner container 2 (article) in which yellow toner is sealed.

  The toner container 2 is attached to an image forming apparatus that performs color printing by an electrophotographic method such as a multifunction peripheral. When printing is performed in the image forming apparatus, the toner container 2 supplies yellow toner, which is a developer, to a developing device provided in the image forming apparatus. The toner supplied to the developing device is supplied to the peripheral surface of the photosensitive drum by the developing device and adheres to the portion where the electrostatic latent image is formed on the peripheral surface. As a result, a toner image is formed on the peripheral surface of the photosensitive drum (development process). The same development processing is performed for the other color toners, and the toner image on which the toners of four colors of CMYK are applied is transferred to the intermediate transfer belt.

  The toner image formed on the intermediate transfer belt is transferred to a sheet that is conveyed while being pressed and clamped by a transfer roller and the photosensitive drum. The sheet on which the toner image has been transferred is subjected to a fixing process by heating by a fixing device and discharged to a discharge tray, and printing is completed.

  The toner container 2 having a horizontally long columnar shape is wrapped with a cushioning material such as an air packing (not shown), for example, and further packed at the packing material 1 with both ends fixed with an unillustrated foamed polystyrene or paper fixing member. The The fixing member has a shape in which the inner side is fitted to the end portion of the toner container 2 and the outer side is fitted to the inner side surface of the packing material 1. By being packed in this way, the toner container 2 is fixed inside the packing material 1, and the toner is transported in the distribution process by the fixing action to the packing material 1 by the fixing member and the buffering action by the buffer material. It will be protected from the impact applied to the container 2.

  The packing material 1 includes a packing unit 11 which is a main body for packing the toner container 2 and a display unit 10 printed on the surface of the packing unit 11. The display unit 10 is provided at a substantially central portion of the side surface excluding the top surface and the bottom surface of the packing unit 11, and a display regarding the toner container 2 such as a name and a color is printed.

  FIG. 2A is an overall view of the display unit 10. The display unit 10 is printed with a color display unit 100 that is solidly printed in yellow to make the toner color yellow of the toner container 2 visible, and character information that indicates the name of the toner container 2 and the corresponding model. And a character part 110.

  When the toner container 2 is packed in the packing material 1, the user cannot visually recognize it from the outside. Here, in order to clearly indicate that the content of the packaging material 1 is the toner container 2, even if a photograph or a diagram showing the appearance of the toner container 2 is printed on the surface of the packaging material 1, the packaging material 1 is enclosed in the toner container 2. Since the color of the toner and the color of the outer case of the toner container 2 are different, the user cannot know the color of the toner. Further, if the display unit 10 is configured only by the character part 110 on which the character information is printed and the toner color is merely displayed as the character information, the user cannot intuitively grasp the toner color.

  Therefore, the display unit 10 is provided with a color display unit 100 in addition to the character unit 110, and the toner color of the toner container 2 is yellow printed on the color display unit 100, thereby being enclosed in the toner container 2. This makes it easy for the user to intuitively understand the color of the toner.

  As shown in the enlarged view of FIG. 2B, the color display unit 100 includes a first layer 101 that is solidly printed with yellow, for example, water-based ink, and a first layer that is green, for example, with water-based ink that is lighter than yellow. And a second layer 102 dot-printed on 101. That is, as shown in FIG. 3, which is a cross-sectional view taken along the line III-III in FIG. 2B, the first layer 101 made of yellow ink is formed on the surface of the packing portion 11, and further made of green ink on the first layer 101. The second layer 102 is formed in a halftone dot shape.

  When the color display unit 100 does not include the second layer 102, the yellow solid printing of the first layer 101 is made of the material of the packing unit 11 because both the hue difference and the brightness difference are small between yellow and brown. It is buried in the brown color of a certain brown cardboard. As a result, the original purpose of allowing the user to intuitively grasp the toner color cannot be achieved. On the other hand, when the green halftone dots of the second layer 102 are regularly scattered on the yellow solid print of the first layer 101, the visibility of the yellow solid print is improved by the green halftone dots. . Therefore, the yellow solid print is visually recognized as yellow without being buried in the ground brown color.

  However, if the density of the halftone dots of the second layer 102 printed with green ink is too high, it will be visually recognized as green of the second layer 102 instead of yellow of the first layer 101. Conversely, if the density of the halftone dots of the second layer 102 is too low, the yellow yellow color of the first layer 101 will be buried in the brown color that is the ground color of the packaging material 1. That is, in any case, the purpose of allowing the user to visually recognize yellow, which is the original color of the toner, cannot be achieved. Therefore, the halftone dots are preferably drawn at a resolution of 20 to 30 lpi (lines per inch), more preferably at a resolution of about 30 lpi.

  In this example, the character portion 110 is printed in the same color green as that of the second layer 102, but it is needless to say that the color of the character portion 110 need not be the same color as that of the second layer 102.

  As mentioned above, although the packaging material 1 which concerns on embodiment of this invention was demonstrated, this invention is not limited to this, For example, the following modified embodiment can also be taken.

  (1) In the above embodiment, brown cardboard is used as the material of the packaging material 1, but the color of the cardboard of the material is not limited to brown, and may be white cardboard or color cardboard. Also in this case, the first layer solid-printed with the first color having a small hue difference and / or lightness difference with respect to the ground color of the cardboard and the second color having a lightness lower than that of the first color. If the second layer printed with halftone dots is formed on the first layer, the first color is visible as the color without being buried in the ground color.

  (2) In the packaging material 1 formed from the brown cardboard in the above embodiment, the color of the first layer 101 is yellow and the color of the second layer 102 is green, but the color of the first layer 101 is gray, second Even when the color of the layer 102 is black, the gray of the first layer can be clearly distinguished from the brown which is the ground color of the packaging material 1 and can be visually recognized.

  (3) In the above embodiment, the packing material 1 is a substantially rectangular box formed from tea cardboard, but the material and shape of the packing material are not limited to this, and for example, a square pole having a trapezoidal bottom or It may be a cardboard or resin packing material formed into a shape having a space inside a quadrangular pyramid or the like.

  (4) In the above embodiment, the article to be packed in the packing material 1 is the toner container 2 that encloses yellow toner, but the article to be packed is not limited to this. Any article having a color characteristic such as a binder may be used.
