Description

Field of the Invention This invention is related to the printing method that prints on the surfaces of various materials or objects by using an ink jet printer.

Background of the Invention Since ink jet printers use water ink, their printing media are generally restricted to materials with good water-based ink absorption. It is extremely convenient for an ink jet printer to print on various materials. Especially, it is convenient for the ink jet printer to print with water ink on products on which the surfaces heretofore have been painted by hand with oil ink, paints, and the like. That is, selected images are easily created by using the image processing function of personal computers and the created images printed repeatedly within a short period of time by using an ink jet printer with water-based ink.

Summary of the Invention With the foregoing in mind, an object of this invention is to provide a printing method that can simply and efficiently create ink images on the surfaces of various products with water-based ink by using the ink jet head.

Also, an object of this invention is to provide a printing method that prints on the surfaces of various materials by using water-based ink, including glass objects, game balls, heads for toy dolls, fruits and vegetables of some types, and other objects. In order to print with water based ink using a movable print head, the invention also has as an objective providing a method of moving the print head to multiple printing positions transversely of the support for the objects to which the ink image is being applied so as to print upon multiple articles or objects arranged transversely of the width of the range of movement of the print head.

The above objects may be attained by printing on the objects using an ink jet printer of the type disclosed in the pending U.S. patent application serial number 500,979, filed February 15, 2000 and assigned to the assignee of the present application.

The printer disclosed in that pending application is one which has an ink jet print head for printing upon articles which may require adjustment of the distance between the object of the printing and the print head to enable printing upon articles of different thicknesses or heights from the article support and the surface upon which the head applies the water-based ink. The disclosure of that pending application is incorporated herein by this reference.

Figs. 4(a) and 4(b) show printing upon inserts for markers, such as tombstones;

Fig. 5 shows printing on transparent material; and Fig. 6 shows printing on transparent material that is mirrored.
Description of the Preferred Embodiment Referring to Fig. 1(a) and Figs. 1(b) through 1(d), the invention is shown in a printing method that prints on the surface of the board medium 32 by applying the first printing P1 with the specified width W1 on the surface of the said board medium by the said ink jet head 31, then moving the home position HP1 to the specified distance L1 of the printing head and applying printing P2 at the adjacent position in the transversely spaced home position HP2 with water based ink.

These views indicate an example of the printing by three printing movements transversely relative to the surface of a medium 32 by shifting the home position of the print head to HP1, HP2, and HP3 for each printing. The number of movements of the home position, can be any necessary or desired plurality of home positions. The medium may also be fed longitudinally by the usual feed mechanism of such ink jet printers, as more fully disclosed in the aforementioned patent application.

Referring to the Figs. 2(a) and 2(b), the invention of the present application creates a water ink image receiving layer 42 on the surface 41a of the medium (41), which in this case is spherical and may be a game ball or other similar articles, including fruit and vegetables of appropriate shapes and sizes, followed by printing with water ink on the surface of this image receiving layer 42. Next, a protection layer 44 is applied on the surface of the printing layer 43. The protection layer 44 has at least one layer of ultraviolet ray resistance or absorption agent, or layer 44 may provide water resistance. The said medium (41) is a golf ball 48 or other similarly shaped article.

In this case, as indicated in Fig.2 (a), for example, the game ball 48 can be placed on one or more indented parts 45 that can fit the game ball 48 or the medium transporting tray 46 with a hole on the surface of and transported through the printing position of the ink jet head 47 that moves back and forth within the specified position that is perpendicular to the transportation direction of the medium tray 46. The movement of the tray 46 as indicated by arrow 46a may be caused by the feed mechanism of the aforementioned U.S. patent application.

The invention of the present application also includes the method that creates a water ink image receiving layer on the surface of other types of media, applies printing with water ink on the surface of this image receiving layer, and creates the protection layer on the surface of the created printing layer.
The medium may be a food product with water resistant surface such as a fruit like an apple and a pear, and the like, and a vegetable like a green pepper. The image receiving layer is made of a water absorbent food product such as seaweed and gelatin or materials that are harmless to the human body.

Also, the printing method may be employed to print with water ink on the surface of still other edible media such as a food product with water absorbent surface such as a vegetable, a takoyaki, and a rice cracker, and the like. The said water ink is made of food materials such as food coloring or other materials that are harmless to the human body.

Referring to Figs. 3(a) and 3(b), the invention of this patent application is a method of printing on items such as a doll head 73 by printing on the first material 71 and the second material 72. It has a step of printing on the surfaces 71a and 72a of the said first material 71 and the said second material 72 by using an ink jet head. An example indicated is an example for printing the face side of the first material 71 and the back side of the second material 72, as the transport moves through the ink jet printer, while the print head is moved, as described above.

The method of creating the protection layer 75 on the surface of the created printing layer 74 on the surfaces 71a and 72a of each material 71 and 72, the protection layer 75 has at least one characteristic of ultraviolet ray resistance or absorption, or water resistance.

Furthermore, it is desirable for the said image receiving layer 76 to have water absorption including the steps of creating the water ink image receiving layer 76 on the surfaces 71a and 72a of each material prior to printing.

Next, referring to Figs. 4(a) and 4(b), the invention of this patent application includes creating indented portion 103 of the panel 102 on the surface of tombstone body, printing on the surface 102a of the panel 102 with the ink jet head, and inserting the said panel 102 in indented part 103 on the surface of the said tombstone to be stabilized. It is a manufacturing ._.._., ,. _ _ method of tombstones that has features of creating the water ink absorbent image receiving layer 104 on the surface 102a of the said panel, printing on the surface of this image receiving layer 104, and creating the ultraviolet ray resistant or absorbent protection layer 106 or a water proof layer on the surface of the created printing layer 105. In practice, a number of the panels or blocks can be printed in a printing method as previously described.

Referring to Fig. 5, the method includes the steps of painting a primer 2 with a ultraviolet rays resistant or absorbent characteristic on the back la of the water resistant light penetrating medium 1, creating the water ink image receiving layer 3 on the surface of this primer 2, applying specific printing 4 on the surface of image receiving layer 3, and creating an ultraviolet ray resistant or absorbent protection layer 5 on the created printing 4.

The light penetrating media 1 can be glass, a clear plastic board, a CD case, a DVD case, or a cassette tape case, and other transparent media.

Referring to Fig. 6, the invention is a mirror manufacturing method that has the steps of creating an ultraviolet ray resistant or absorbent protection layer 22 on the back 21a of a glass panel 21, creating a water ink image receiving layer 23 on the surface of this protection layer 22, applying the specified printing on the surface of this image receiving layer 23, creating a water proof layer 25 on the surface of the created printing layer 24, and creating a reflection film 26, such as silver, on the surface of this water proof layer 25.

The water ink image receiving layer can be created by a spray gun painting method, a spin coating painting method, screen printing, or hand painting.

Also, the protection film on the printing surface can be created by a spray gun painting method, a spin coating painting method, screen printing, or hand painting.

The image receiving layer has excellent water ink absorption. For example, its main components are water (emulsion, water solution) acrylic resin, vinyl alcohol resin, and acetic acid vinyl resin. It is created by painting and drying a mixed solution of foam remover, surface adjuster, surfactant, adherence enhancer, water, and alcohol solution.

Also, the protection film on the printing surface is a layer to prevent discoloration of the printing layer and to improve water resistance. For example, its main components are acrylic resin, silicon acrylic resin, and polyester resin. It is crated by painting and drying the mixed solution of organic and inorganic ultraviolet ray absorbent material, oxidization preventing material, hulse, foam remover, surface adjuster, and solution.
