When three primary color inks and a particular color ink having a hue different from those of the three colors are used, the number of passes with regard to the same printing area is changeable, thereby speeding up a printing operation and improving color development at a gamut expressed by the particular color ink to achieve high quality images. Use or non-use of the particular color ink is switched according to the number of passes corresponding to quality information. If a high speed data generation processing is not required but sufficient color development is achieved, namely if the number of passes is large, the use of the particular color will expand the color reproduction gamut. If the high speed is required, namely if the number of passes is small, non-use of the particular color ink will reduce the number of colors of the usable inks.

Cultured Penaeus vannamei Boone has the advantages of high growth speed, strong adaptability and high yield and becomes one of the main cultured varieties in northern areas of China. (1) pond water color control: the ideal color of water for culturing the Penaeus vannamei Boone is yellow green or yellow brown formed by green algae or diatoms; the algae or diatoms are benign biocenosis in the micro-ecological environment of a pond and play a role of purifying water quality; (2) control of pond water pH value, dissolved oxygen and transparency: the pH value suitable for the Penaeus vannamei Boone is 7.8-8.5, but the peak value of 9.2 is generated at the middle and final stages culturing, and therefore, the pH value control is especially focused in the culturing process; the pH value is not suitable to be high, otherwise, the toxicity of ammonia nitrogen can be increased, thereby restraining the growth of the Penaeus vannamei Boone; (3) scientific bait casting: generally, low-cost iced fish cream or small shells are fed, and some formula feeds are also fed; the formula feeds can be manually compounded; the formula feeds contain the following components: 17 percent of fish meal, 40 percent of soya-bean cake, 28 percent of bran, 10 percent of wheat middling, 3 percent of bone meal and 2 percent of additive; and (4) pond patrol: the pond is patrolled in the morning, at night and in the midnight every day to observe the water color change and whether Penaeus vannamei Boone raise above water to breathe or not; the activity condition, the growth condition and the repletion rate of the Penaeus vannamei Boone are observed by adopting two methods of lamplight observing and spoon-net inspection so as to regulate the bait casting amount and decide whether to start an oxygen-enriching machine or not.

A printer comprises an ink-jet head, and a control unit which has a judgment pattern printing control section. When a judgment pattern is printed, the judgment pattern printing control section allows the discharge of ink droplets of a second color to an area on which ink droplets of a first color are to be landed, before discharging the ink droplets of the first color having a small color difference with respect to a color of a medium. Accordingly, the ink discharge malfunction is reliably judged for the nozzle irrelevant to the color of the recording medium and the color of the ink discharged from the ink-jet head.

Color production with high chroma in a low lightness portion is realized by using an appropriate complementary color ink to a particular color ink reproducing the low lightness portion. More specially the device secondary color G-K is reproduced with ink of the pure color component composed of the color mixture of the particular color G ink and the basic color Y ink to tone the particular color G ink. In addition, as complementary color components, the particular color R ink and K ink are used. Thereby, the reproduction line is substantially linear from the device secondary color G point to the device K point. In color reproduction at the dark portion of the color on the G-K line, sufficient chroma can be obtained.

The invention discloses a domestication method for microorganisms for performing purification treatment on cold-rolling organic wastewater. The domestication method comprises the following steps: step S1, injecting clean water into a biological contact oxidation tank, starting aeration, and feeding a strain and a nutritional agent; step S2, continuously culturing the strain for one week to ensure that aerobic microorganisms are gradually reproduced until successfully forming a bio-film; step S3, adding the cold-rolling organic wastewater into the biological contact oxidation tank, and stopping feeding water until the color of water in the biological contact oxidation tank is changed into green brown from yellow brown; step S4, increasing the aeration amount to perform stuffy aeration culture; step S5, gradually increasing the water feeding load, and continuously repeating the process from the step S3 to the step S4 until the water feeding load exceeds 300% of the design load to successfully domesticate the aerobic microorganisms. According to the domestication method disclosed by the invention, the cultured and domesticated aerobic microorganisms can have stronger vitality and higher capacities of degrading organic matters in the wastewater after generating variations so as to ensure that the cold-rolling high-concentration organic wastewater can be treated and can meet the discharge standards, and the running cost can be greatly reduced.

In image processing, it is possible to suitably reduce density unevenness and graininess according to the ink used in printing. More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.
