摘要:
An ink jet printing method makes it possible to prevent bleeding, which may take place if non-permeative ink of different colors are in contact with each other on a paper sheet, by selecting according to image information either a step A of providing a processing liquid, at first, in the area on a printing material for images to be printed thereon, and then, providing such ink or a step B of providing such ink, at first, in the area on the printing material for images to be printed thereon, and then, providing such liquid.

In an ink-jet printing apparatus in which an ink and a liquid S which insolubilizes or coagulates a dye contained in the ink are ejected to perform printing, in order to reduce consumption of the liquid in the case of employing a printing method where one pixel is formed by a plurality of scanning cycles of a head, when printing a pixel represented by red print data, a yellow ink and a magenta ink are ejected in the first to the third scanning cycles, and the liquid S is ejected only in the third scanning cycle.
摘要:
An apparatus for performing printing by employing an ink and a liquid which insolubilizes or coagulates the ink, in order to effectively obtain an effect of using the liquid and to improve printing quality, is provided. The liquid S to be applied to respective pixels of regions printed by performing two scanning cycles, is applied to different two patterns of pixels from each other during first and second scanning cycles.
摘要:
An ink jet printing method forms an image by ejecting a printing property improving liquid which improves printing property of ejected ink onto a printing medium in advance of ejection of the ink onto the printing medium, and ejecting the ink to the printing property improving liquid applied on the printing medium. The ink is ejected onto the printing property improving liquid layer under a condition where a specific relational expression of a thickness of a liquid layer of the printing property improving liquid covering a region of the printing medium to be covered with the ink after impacting the ink thereon, a diameter of the ejected ink and ink ejection speed and so forth is satisfied.

A transport system composed of road side stations installed along roads and vehicles running on roads, wherein emergency processing at the time of an accident, a local information providing service, and so on are realized by the road side stations in cooperation of the road side stations and the respective vehicles. In the transport system, a plurality of road side stations are interconnected through a road side communication network, and a plurality of vehicles communicate with the road side stations. A vehicle transmits a request message containing a service code and location information. A road side station receiving the request message broadcasts the request message to the network. The road side stations receive the message, and determine whether or not requested processing should be executed based on the service code and the location information. When determining that the processing should be executed, the road side station executes processing indicated by the service code.
摘要:
It is an object to provide an ink-jet recording apparatus capable of always obtaining an image having a high quality without difficulty for a user by precisely detecting a cause which deteriorates image quality and by efficiently resolving the cause. The cause of the deterioration in image quality is detected on the basis of a difference S between image data G intended to be recorded and read data Y which is obtained by reading the image that is recorded on a recording medium (S=G−Y), thereby determining a processing method for resolving the cause. The determined processing method is executed and, thus, normal recording is always possible.
摘要:
A liquid composition for ink-jet recording, or an ink set for ink-jet recording which produces an image having water resistance and excellent print quality, and which can reduce color bleeding that occurs in formation of color images, and furthermore, which can extend a life-span of ink-jet recording heads, as well as an ink-jet recording method, a recording unit, an ink cartridge and an ink-jet recording apparatus are provided. The liquid composition or a color ink constituting the ink set comprising a polyvalent metal salt, a material selected from the group consisting of acids including amino groups and salts thereof, and a liquid medium is used.
摘要:
A liquid ink jet recording apparatus and method which forms a multi-level tonal image by liquid droplets discharged through plural nozzles. A first scan of a recording head past a recording material ejects ink droplets from a first nozzle in accordance with a tone signal. A sub-scan operation is performed and a second scan of the recording head ejects ink droplets from a second nozzle in accordance with a tone signal. The ink droplets ejected from the first and second nozzles have actual size/volumes different than their nominal size/volumes. Plural tonal levels are formed by super-imposing ink droplets of the same color and a same nominal volume but different actual volumes by at least the first and second nozzles thus minimizing variations between pixels having the same tonal level.
摘要:
An ink jet recording method and apparatus for performing recording by discharging ink onto a recording medium in accordance with recording data using a recording head having ink discharge ports for discharging the ink. The apparatus includes a scanning unit for scanning the recording head relative to the recording medium for discharging ink to record pixels on the recording medium, and a determining unit for determining whether the recording data includes non-discharge data for a predetermined number of successive pixels to be recorded by the recording head, and for generating a corresponding determination output signal. The apparatus further includes a control unit for controlling ink discharge in accordance with the determination output signal such that an amount of ink discharged for forming at least one pixel subsequent to the predetermined number of successive pixels is reduced from a predetermined recording amount, when the recording data is determined to include non-discharge data for the predetermined number of successive pixels.
摘要:
A liquid jet recording apparatus for recording on a recording material with liquid droplets discharged through plural scanning nozzles. The number of the nozzles "n" (n.gtoreq.2) arranged at a pitch "P" (.mu.m), the distance "s" (.mu.m) of relative movement between the nozzles and the recording material between adjacent scans, the maximum number of ink droplets per pixel and per scan "k" (k.gtoreq.1), and the number of tone levels "g" are selected so as to satisfy the relationships: n/(s/p).gtoreq.2; and n/(s/p).times.k=g-1.
