    • A inkjet recording method is provided in which occurrence of curling at the time of double-sided recording is prevented. In the method, an inkjet recording medium is used which includes resin coated paper having a resin layer A of thickness “a” at one side of base paper, and a resin layer B thinner than the thickness “a” by a thickness of 3 μm to 20 μm at the other side of the base paper, and ink receiving layers each of which includes an inorganic pigment and a binder and are provided at both sides of the resin coated paper; and an image is recorded on the ink receiving layer at the resin layer B side of the resin coated paper, and subsequently an image is recorded on the ink receiving layer at the resin layer A side of the resin coated paper.
    • 提供一种喷墨记录方法,其中防止在双面记录时发生卷曲。 在该方法中,使用喷墨记录介质,其包括在原纸一侧具有厚度“a”的树脂层A的树脂涂布纸和厚度为3μm的厚度比“a”薄的树脂层B 在原纸的另一侧为20μm,油墨接收层各自包括无机颜料和粘合剂,并且设置在树脂涂布纸的两侧; 并且在树脂涂布纸的树脂层B侧的油墨接收层上记录图像,随后在树脂涂布纸的树脂层A侧的油墨接收层上记录图像。

    • An image forming system includes: a recording medium which has a roll shape and is manufactured so as to have both edges curling in a direction opposite to a roll surface of the recording medium; an image forming device which forms an image on the recording medium conveyed along a conveyance path; a recording medium feeder in which the recording medium having the roll shape is loaded in such a manner that the recording medium having the roll shape is conveyed while the roll surface of the recording medium faces the image forming device; a rear end cutter for cutting the recording medium having the roll shape on which the image forming device has formed an image on the roll surface at a position posterior to the formed image; a reverse conveyance path in which the recording medium, on the roll surface of which the image has been formed and which has been cut by the rear end cutter, is reversed in terms of front and back surfaces of the recording medium; and a decurl device for reversing a curl direction of the recording medium which has been reversed in terms of the front and back surfaces and is conveyed in the reverse conveyance path, wherein images are formed on the front and back surfaces of the recording medium by forming an image on the front surface of the recording medium having the roll shape, cutting the recording medium at the position posterior to the image, reversing the recording medium in terms of the front and back surfaces, reversing curl of the edges of the recording medium in an opposite direction by the decurl device, and then forming an image on the back surface of the recording medium.
    • 图像形成系统包括:记录介质,其具有辊状并被制造成具有沿与记录介质的辊表面相反的方向卷曲的两个边缘; 图像形成装置,其在沿着传送路径传送的记录介质上形成图像; 记录介质供给器,其中具有卷状形状的记录介质被装载成使得当记录介质的辊表面面向图像形成装置时具有辊状的记录介质被传送; 用于切割具有辊形状的记录介质的后端切割器,图像形成装置在其上形成在形成图像后面的位置的辊表面上的图像; 在记录介质的表面上已经形成图像并且被后端切割器切割的记录介质在记录介质的前后表面上相反的反向传送路径; 以及用于反转已经在前表面和后表面反转的记录介质的卷曲方向并且在反向输送路径中被传送的去卷曲装置,其中通过形成在记录介质的前表面和后表面上形成图像 在具有卷状的记录介质的前表面上的图像,在图像后面的位置切割记录介质,使前后表面反转记录介质,使记录介质的边缘的卷曲反转 通过分解装置的相反方向,然后在记录介质的背面上形成图像。

    • An image is recorded by ejecting two or more ink compositions on a porous layer that contains inorganic microparticles and a water-soluble resin and has a porosity [%] of 50% or more with a maximum total ejection amount (mL/m2) set at less than 90% of an absorption capacity (mL/m2) of diethylene glycol in the porous layer. The porosity=(absorption capacity of diethylene glycol (mL/m2))/(thickness of porous layer (μm))×100. The maximum total ejection amount=(maximum ejection amount of one dot (mL/m2))×(total amount of ink (%)). An inkjet recording method capable of inhibiting color change from occurring to cause color irregularities when papers are stacked on an image portion within a relatively short time after recording in high-speed processing or processing of a large number of sheets, and capable of stably obtaining images recorded with desired color tone.
    • 通过在包含无机微粒和水溶性树脂的多孔层上喷射两种或更多种油墨组合物并且具有50%以上的孔隙率[%],最大总喷射量(mL / m 2)设定在 在多孔层中小于90%的二甘醇的吸收能力(mL / m 2)。 孔隙率=(二甘醇的吸收容量(mL / m 2))/(多孔层的厚度(μm))×100。 最大总喷射量=(一个点的最大喷射量(mL / m 2))×(油墨总量(%))。 能够在记录高速处理或处理大量纸张之后的相对短的时间内将纸堆积在图像部分上时能够抑制发生颜色变化的颜色变化的喷墨记录方法,并且能够稳定地获得图像 用所需的色调录制。
