It relates to a recording method.

An ink jet recording apparatus capable of printing with zero margins at the front, rear, left, and right edges of a recording medium is disclosed (see, for example, Patent Document 1 and Patent Document 2).
According to the recording apparatuses disclosed in these publications, the scanning operation of the recording head mounted on the carriage is set so as to move to a position outside the left and right edges of the recording medium, and the printing operation is executed. It is configured.

  When printing with this ink jet recording apparatus, as shown in FIG. 5A, the recording paper 100 as a recording medium is conveyed in the sub-scanning direction of the arrow A, and the leading edge 100A of the recording paper 100 is recorded. When reaching below the head 101, the carriage reciprocates along the main scanning direction indicated by the arrow B, and ink 102 is ejected from the recording head 101 to start printing on the recording paper 100.

  At this time, in order to perform printing with the margin of the leading edge 100 </ b> A on the recording paper 100 being zero, the ink 102 protrudes outward from the leading edge 100 </ b> A of the recording paper 100.

  According to the ink jet recording apparatus 10 using this pigment ink, the recording head 11 is scanned along the guide shaft 12 by moving the carriage 16 along the guide shaft 12 in the main scanning direction indicated by the arrow B. When the recording paper 13 is fed in the sub-scanning direction (arrow A) perpendicular to the scanning direction of the recording head 11, ink is ejected from the cartridges 17 and 18A to 18C via the nozzles 11A to 11B. Thus, printing can be performed on the recording paper 13.

  Next, an ink jet recording method of the ink jet recording apparatus 10 using pigment ink will be described with reference to FIGS.

  When printing is performed by the ink jet recording apparatus 10 using pigment ink, as shown in FIG. 2A, the leading end 13A of the recording paper 13 is conveyed below the recording head 11 by being conveyed in the sub-scanning direction indicated by the arrow A. , The carriage reciprocates along the main scanning direction indicated by the arrow B, and the pigment ink 14 is ejected from the recording head 11 to start printing on the recording paper 13.

  In this state, when the recording paper 13 is conveyed in the sub-scanning direction indicated by the arrow A, when the state shown in FIG. 2B is reached, the margin of the side edge 13B of the recording paper 13 is set to zero to perform printing. By appropriately adjusting the reciprocating distance of the carriage along the B main scanning direction, the pigment ink protrudes from the side edge 13 </ b> B of the recording paper 13 to the outer side 14.

  Further, when the recording paper 13 is transported in the sub-scanning direction indicated by the arrow A from this state, when the state shown in FIG. 2C is reached, printing is performed with the margin of the trailing edge 13C on the recording paper 13 set to zero. Then, the pigment ink 14 protrudes from the rear edge 13C of the recording paper 13 (see FIG. 3).

  Here, the pigment ink 14 that protrudes outward from the front edge 13A, the side edge 13B, and the rear edge 13C of the recording paper 13 is soaked into the platen 15 shown in FIG. The platen 15 is selected from the group consisting of the above-described fluororesin, silicone resin and silicone oil as a dispersion or solution containing a resin component throughout the entire region from one end 15A to the other end 15B.

Thereby, when printing on the next recording paper 13, it can prevent that the end surface of the recording paper 13 contacts a pile and the end surface of the recording paper 13 gets dirty.

  The platen 15 is impregnated with a dispersion or solution containing a resin component over the entire region from one end 15A to the other end 15B. For this reason, the ink that has soaked into the platen 15 from the front edge 13A, the side edge 13B, and the rear edge 13C of the recording paper 13 can be soaked into the entire region from the one end 15A of the platen 15 to the other end 15B. Accordingly, since a large amount of pigment ink can be infiltrated into the platen 15, the cycle for replacing the platen 15 can be extended.
