PROBLEM TO BE SOLVED: To provide a method of detecting faulty discharge in an inkjet recorder capable of identifying a nozzle in a faulty discharge state even when an end portion of a test pattern is not recorded on a recording medium.SOLUTION: The method of detecting faulty discharge in an inkjet recorder 1 includes a test pattern recording step of recording a test pattern 31 on a recording medium 5, a test pattern reading step of reading the test pattern 31 by means of a scanner section 11, and a faulty discharge determination step of determining an image with faulty discharge on the basis of image data read in the test pattern reading step. In this state, the test pattern 31 includes at least two reference marks 47 arranged in a width direction of the recording medium 5, which are reference marks 47 for determining a position reference between the recording medium 5 and a recording head 8, and further includes a faulty discharge nozzle position calculation step in which the reference marks 47 are detected when it is determined that image data has an image with faulty discharge, and thereby a position of a nozzle in a faulty discharge state is detected.

PROBLEM TO BE SOLVED: To provide a fluid jetting apparatus suppressing variation in the drying time. SOLUTION: The fluid jetting apparatus forms a first image with a first fluid and a second fluid, and forms a second image with the second fluid on the first image in another image forming operation after providing the drying time. First nozzles and second nozzles for forming the first image are located upstream in a conveying direction from second nozzles for forming the second image. Ink droplets are not jetted from nozzles located downstream in the conveying direction from the first and second nozzles for forming the first image, and located upstream in the conveying direction from the second nozzles for forming the second image, and also belonging to a region whose length in the conveying direction is integer times as long as a predetermined conveying amount 3d.

PROBLEM TO BE SOLVED: To provide an inkjet recording method capable of materializing remote proofing in package printing for printing a color image on a white ground by an inkjet method, and to provide a printed matter obtained by the inkjet recording method. SOLUTION: In the recording method, a printed unit D1 between a white solid coating layer W1 and a non-white pattern layer P1 is printed on the surface of a long-sized film base S1 by using two inkjet printers, wherein, in an opaque substrate (A), the white solid coating layer is disposed by the first printer and the non-white pattern layer is disposed by the second printer from above the dried layer thereof, in an transparent substrate (B), the non-white pattern is disposed by the first printer and the white solid coating layer is disposed by the second printer from above the dried layer, or in the transparent substrate (C), the non-white pattern layer or the white solid coating layer is disposed on one surface of the transparent substrate by the first printer and the white solid coating layer or the non-white pattern layer is disposed by the second printer on the other surface of the transparent substrate.

PROBLEM TO BE SOLVED: To appropriately satisfy demands for high image quality and high productivity and to enable highly reliable printing by setting the number of recording paths and the head-platen distance, which are optimal, in accordance with contents of the images to be printed and demands of a user (for example, to importance on quality or to put importance on the speed). SOLUTION: In a recording device, it is selectable to execute or not to execute the process of giving an instruction for setting the number of recording paths and the head-platen distance in accordance with determination of the contents of the images. Then, when execution of the process is selected, the number of recording paths and the head-platen distance are appropriately set in accordance with the contents of the images (duties, etc.). On the other hand, when it is not selected, one-path recording is carried out regardless of the contents of the images, and a comparatively wide head-platen distance is set.

PURPOSE:To obtain a uniform recording width and make high-quality recording possible on a recording medium of any thickness by detecting a thickness of the recording medium and controlling to a constant of deviation quantity of ink drop by feeding said detection signal to charging and deviation circuits. CONSTITUTION:A successive series of ink drops 5 is charged electrically from loading circuit 13 and loading electrodes 6 according to a signal delivered from a generating circuit 12 of loading pulse according to a recording information. On the other hand, a thickness detector 11 measures a thickness of recording medium 9 and delivers its result to a load correcting circuit 14 as an output. In the load correcting circuit 14 delivers load correcting voltage corresponding to a thickness of recording medium 9 to a load circuit 13 as an output to correct a voltage at the loading electrodes 6. For instance, when a thick sheet of paper is employed for the medium 9, an output of positive voltage from the load correcting circuit 14 is delivered correspondence to the thickness of the medium 9 resulting the higher loading voltage and increased load quantity of ink drops. By this arrangement, ink drops get larger deviation angles at the deviation electrodes 7a, 7b and on the recording medium, constant recording width can be obtained on the medium 9 regardless of the thickness.
