Definitions

  • the present invention relates to an ink jet printer for sequentially printing color patterns or characters onto the surface of a continuous length of belt shaped article running continuously.
  • Printing by ink jet printers differs from that of, for example, subliming heat transfer and melting heat transfer in that it has a variety of benefits which are expected to be applicable to a wide range of fields.
  • this type of printing is known as the "non-contact type" of printing, as the printer does not come into contact with the surface being printed. This means that in addition to being able to print reliably onto flat surfaces, the printer can also print directly onto rough or highly flexible surfaces.
  • the apparatus can be simple as no transfer or fixing is required.
  • simple colors in addition to fluorescent or special colors can be faithfully reproduced with little color shift and can be clearly printed.
  • ink jet printers have the benefits described above, they cannot be applied to woven fabrics such as fashionable articles, production brand clothing and bags. This is because from a production point of view the print efficiency it not of the standard required and they are too expensive. It is necessary for the printers to be able to handle successive printing and cope with the differing widths which various woven fabrics to be printed on will have. It is also necessary for them to be able to cope with a continuous or substantially endless length, they should be capable of high speeds to increase production and should cope with changes in width easily.
  • two nozzles are moved 0.56 mm across the width of the surface to be printed while printing at the same time, after which they are sent a distance equal to one dot length 0.14 mm along the length of the surface to be printed. The two nozzles are then sent back the 0.56 mm along the width of the surface to be printed while printing at the same time.
  • an ink jet printer equipped with a number of multinozzle heads each having n number of nozzles at regular spaces of p mm, for printing color patterns or symbols in a width of w (mm) onto a continuously travelling belt shaped article, wherein the total quantity of the multinozzle heads is w/(nXp) pairs, the nozzles of each of the multinozzle heads being arranged in a direction perpendicular to the direction of travel of the belt shaped article, all of the multinozzle heads being positioned successively along the path of travel of the belt shaped article, the nozzles of each pair of the multinozzle heads being shifted down by 0.5Xp (mm), the nozzles of all of the multinozzle heads being staggered so as not to overlap one another transversely of the path of travel of the belt liked article.
  • each nozzle head have n number of nozzles at regular spaces of p mm and partly since there are w/(nXp) pairs of the multinozzle heads in total, it is possible to simplify the printer structure and realize an improved printing speed, which is 2w/(nXp) times that of the conventional printer using only one similar multinozzle head movable back and forth transversely of the belt shaped article by a drive means.
  • FIG. 1 is an outline plan view of an example arrangement of the fixed multinozzle heads for the ink jet printer in the present invention
  • FIG. 2 is a side view of that shown in FIG. 1
  • FIG. 3 is an outline view of the way in which the picture elements output by the ink jet printer usually make up a picture
  • FIG. 4 is a view describing the operation of the nozzle during the formation of one picture element for the printer of FIG. 3.
  • the ink jet printer used employs a multinozzle head which; gives a dot density of 180 dpi; uses a 4x4 matrix to give a tonal range of 16; has a nozzle constant (n) of 12, giving 12 nozzles for each color; and has 4 colors, giving a total of 48 nozzles.
  • the dot density is 180 dpi and a 4x4 matrix is used to give a tonal range of 16
  • the fact that there are 180 dots within one inch means that if the dot is square then the length of one side will be 1 inch/180, which is equal to 25.4 mm/180, which means one side will be 0.14mm long.
  • the dot spacing (p) will then be 0.28 mm (0.14x2).
  • one picture element will have side of length 0.56 mm although this will depend on the use of a 4x4 matrix to give a tonal range of 16.
  • the nozzle spacing within one head (p) is 0.28 mm, that is to say, twice the side length of the dots (0.14 mm).
  • the nozzle spacing within one head (p) is 0.28 mm, that is to say, twice the side length of the dots (0.14 mm).
  • two nozzles would be moved backwards and forwards a distance of 0.56 mm (0.14x4) in a direction at right angles to the direction of movement of the surface which is being printed on.
  • the size of one multinozzle head alone will exceed the 60 mm width of the slide fastener chain.
  • 36 multinozzle heads have been designated to be necessary to cover the 60 mm width of the slide fastener chain.
  • These 36 multinozzle heads are arranged sequentially in pairs diagonally across the slide fastener chain in the manner shown in FIGS. 1 and 2. With regards to each pair of multinozzle heads, one of the pair will be placed at a distance equal to the dot side length of 0.14 mm which is half that of the nozzle spacing (0.14x2) down from the other of the pair across the width of the slide fastener chain. In this way no two nozzle positions of two multinozzle heads will coincide with each other.
  • This invention is not necessarily limited to the head arrangement shown in the diagrams whereby the multinozzle heads are arranged sequentially in pairs diagonally across the slide fastener chain. Any arrangement where the multinozzle heads are arranged along the length of the slide fastener chain in such a way as to cover the width of the chain without any two multinozzle heads coinciding with each other would also be suitable.
  • an ink jet printer which adopts the method of moving six multinozzle heads such as the one used in this invention backwards and forwards across the width of a slide fastener chain to print the width of the chain instantaneously would take four minutes to print an area equivalent to an A4 size (20 cm x 30 cm). This means that this method would print a total of 270 m of slide fastener chain in 15 hours.
  • the ink jet printer in this invention does not require any driving machinery to move it backwards and forwards. It can therefore print 9800 m of slide fastener chain in 15 hours, which is 36 times faster than the conventional printer.
  • the ink jet printer according to the present invention is practical, while at the same time can sequentially print a continuous belt shaped article both inexpensively and at a high speed and yet can still achieve a very high level of production output.
