Abstract: The present invention discloses a method for improving the blood compatibility of a material surface by using a controllable grafting technique. The method involves placing a monomer NVP, an RAFT reagent and a solvent acetonitrile in a container, adding an initiator AIBN, mixing the same uniformly, removing oxygen with liquid nitrogen, making the same react in an oil bath; after polymerization, adding liquid nitrogen to quench and stop the reaction, thus obtaining PVP-COOH; mixing the PVP-COOH with DCC and NHS; adding dry dichloromethane to the mixture in a nitrogen atmosphere, adding mercaptoethylamine, and making the same react in darkness at room temperature; obtaining a crude sample; dissolving the crude sample in water, and performing dialysis with deoxygenated water in darkness, and then obtaining HS-PVP by freeze-drying. An Au—S bond chemisorption method is used to controllably graft an anti-protein high-molecular polymer onto an Au surface.

Abstract: First, image data are converted to first tone data for primary color inks, and then converted to second tone data for primary color and black inks, by under color elimination. The combinations of the above tone data for primary color and black inks, in which bronzing occurs when images are printed on the printing medium, are recorded beforehand as the conditions under which bronzing occurs. The determination of whether or not the conditions under which bronzing occurs are present in the above second tone data is made according to these conditions under which bronzing occurs. If bronzing will occur, a part of the under color elimination is converted to primary color inks. In this way, it becomes possible to print images in which bronzing does not occur. This process may also be executed by using color conversion tables.

Abstract: In a printer that allows dual-way printing, a test pattern is formed to adjust the print timing with a high accuracy, or more concretely to eliminate a deviation of dots created in the course of a main scan in a backward direction from dots created in the course of the main scan in a forward direction. The test pattern is based on a normal dither matrix. The test pattern includes a plurality of dots that are regularly arranged both in a main scanning direction and in a sub-scanning direction. When the test pattern is printed at an appropriate timing, it is observed as a substantially homogeneous state without unevenness of the density. In case that the dot print timing is deviated, on the other hand, a deviation in dot interval causes unevenness of the density. The deviation of the dot print timing is accurately detected, based on the presence or the non-presence of such unevenness of the density.

Abstract: The printing apparatus of the present invention adopts the technique of effectively utilizing two or more different types of dots having different ink densities and different ink weights. The printing apparatus has a head that provides inks of different densities with respect to at least one color and creates dots of different diameters. The density per unit area is varied by changing the combination of the ink density and the dot diameter. In the half tone area, the lightness of smaller dark dots is made substantially coincident with the lightness of larger light dots. Both the smaller dark dots and the larger light dots are created in the half tone, so as to prevent the banding from occurring in a resulting printed image. The smaller dark dots and the larger light dots may be arranged according to a predetermined pattern or at random. The pattern should be set by taking into account the ink duty of the recording paper.
