摘要:
Provided are an ink jet ink set, an ink jet recording method, and an ink jet recording apparatus each of which can reduce the graininess of an image to be recorded and improve the water fastness of the image even in a recording medium such as plain paper. The ink jet ink set has a first ink and a second ink independently, and is used so that the first and second inks overlap each other at least partly upon application of the inks to a recording medium. The first ink contains at least a pigment and a silicone oil. The second ink contains at least a pigment and a graft polymer that includes at least a nonionic unit represented by the general formula (I) and a unit having a polysiloxane structure.
摘要:
A pigment ink is provided which has good ink reliability and storage stability and can achieve superior scratch resistance of images at such a level that coloring materials are hardly scraped off even when images are scratched with finger nails under application of such strong pressure as to scratch a recording medium at its non-recorded areas. The pigment ink contains a pigment, a modified siloxane compound having a specific structure, and a polymer whose acid value and hydrogen bond parameter (δh) are specified.
摘要:
An ink jet recording apparatus includes a recording head including a plurality of recording elements for ejecting ink in accordance with image data, wherein an image is formed by carrying out a recording scan N times for the same image area on a recording material, where N is an integer not less than 1, and a setting unit for setting a value of N in accordance with information relating to a glossiness of the recording material.
摘要:
In both a full-line and a serial printer, the amount of ink passing through nozzles of print heads is sometimes decreased below a normal value before and during actual printing. In the printer of the present invention, a preliminary ejecting operation is performed taking the opportunity in which the amount of ink passing through nozzles is decreased below a normal value. Then, the amount of ink passing through nozzles recovers to the normal value in ink ejection after the preliminary ejecting operation. Since only a small amount of ink is ejected through the nozzles during the preliminary ejection operation, dots formed on a print sheet are not noticeable. Further, it is unnecessary to move the print heads to a home position where an ejection recovering process is executed to remove ink having an increased viscosity.

The present invention provides an ink jet printing apparatus and a preliminary ejecting method. In both a full-line and a serial printer, the amount of ink passing through nozzles of print heads is sometimes decreased below a normal value before and during actual printing. In the printer of present invention, a preliminary ejecting operation is performed taking the opportunity in which the amount of ink passing through nozzles is decreased below a normal value. Then, the amount of ink passing through nozzles recovers to the normal value at an ink ejection after the preliminary ejecting operation. Since only a small amount of ink is ejected through the nozzles during the preliminary ejection operation, dots formed on a print sheet are not noticeable. Further, it is unnecessary to move the print heads to a home position where an ejection recovering process is executed to remove ink having an increase viscosity.

A method for forming spacers according to the present invention is a method for forming the spacers on a substrate, comprising the steps of: supplying adhesive at a position for forming each of the spacers on the substrate by an inkjet system; dispersing beads, each bead having a diameter corresponding to the height of the spacer, so as to adhere the beads to adhesive; and removing the beads that are not adhered to the adhesive from the substrate. A manufacturing method for a color filter having spacers according to the present invention, the method comprises the steps of: forming a color filter by forming on a substrate at least a light-shielding layer having plural apertures and a colored layer having colored portions arranged in each of the apertures of the light-shielding layer; supplying adhesive made of a curable resin composition in regions overlapping the light-shielding layer on the color filter by an inkjet system; dispersing beads on the color filter so as to stick the beads to the adhesive; and removing the beads that are not adhered to the adhesive from the color filter. Furthermore, a liquid crystal element according the present invention comprises: a pair of substrates; and liquid crystal clamped between the pair of substrates, wherein one of the pair of substrates is a color filter having spacers made by the above-mentioned manufacturing method and the distance between the pair of substrates is maintained by the spacers.
