摘要:
An image forming apparatus includes a registration unit which performs colour registration correction by using a registration sensor, an image forming unit which forms a preset first mark whose width is large enough to fall within a range recognizable by the registration sensor on an image forming medium, and a storage which stores a specific area of an image forming medium recognizable by the registration sensor by using the formed preset first mark. The image forming apparatus further includes a controller which controls the image forming apparatus to form a preset second mark to perform colour registration correction within a range recognizable by the registration sensor by using information regarding the specific area which was previously stored in the storage, and the controller controls the registration unit to perform colour registration correction by using the formed preset second mark.
摘要:
A printing method comprising: forming a first image utilizing a liquid toner comprising carrier liquid and pigmented polymer particles having a first color; transferring the first image to an intermediate transfer member; forming at least one additional image utilizing a liquid toner comprising at least one carrier liquid and pigmented polymer particles having a second color, different from the first color; transferring the at least one additional image to the intermediate transfer member overlaid on the first image, to form a composite image on the intermediate transfer member; and further transferring the composite image to a further substrate, wherein said polymer particles in said first liquid toner and in at least one of said additional liquid toners have different compositions, aside from colorants, the differences in composition including at least one of different polymers or blends of polymers, different amounts or types of placticizers, different amounts of solvated liquid and different compositions of solvated liquid.
摘要:
A printing system using a recharge, expose and development image on image process color system is disclosed in which there is an optional gloss development step. The printing system may be a single pass system where all of the colors are developed in a single pass or a multi-pass system where each color is developed in a separate pass. The additional gloss development step results in optimal color quality.
摘要:
A printing machine and method is disclosed, that combines charged image pattern creation techniques of electrostatic imaging with the coloration capabilities of dye sublimation to produce novel color printing systems offering unique advantages in copy quality, costs, speed, and security. Donor particles (24) having a sublimable dye coated thereon are employed with electrostatic imaging techniques to create a temporary donor image. Uniform heat from a heat unit (30) is applied to sublime dyes from the donor particle pattern into the final image support member (20).

A toner is proposed which includes toner particles and a fluidity-imparting agent and have such characteristics that the toner particles has an average circularity of 0.93 to 0.97, and that a residue of the toner is in an amount of 10 mg or less when 100 g of the toner is sieved with a 500-mesh sieve, which toner is for use in an electrophotographic image formation method using an intermediate image transfer method. A full-color image formation method, using this toner, and an image formation apparatus in which this toner is used are also proposed.
摘要:
Disclosed is a color image forming apparatus in which a plurality of developed images superposed one upon the other are transferred onto a recording medium. The transfer capability of the developing agent is improved by using a first developing agent containing a additive having a small average particle diameter, followed by using a second developing agent containing a second additive having a large average particle diameter larger. Alternatively, a first developing agent containing a first toner having a small roundness is used first, followed by using a second developing agent containing a second toner having a large roundness. Still alternatively, a first developing agent containing a small amount of a first additive is used first, followed by using a second developing agent containing a large amount of a second additive.
