摘要： Pixel data are processed in digital color printing, by mapping a multi-value input intensity value for a color to be printed into a multi-value first quantity level for a first ink which is the color to be printed, the first ink having a first density. The input intensity value corresponding to the color to be printed is also mapped into a multi-value second quantity level for a second ink which is the color to be printed, the second ink having a second density which is greater than the first density. A four-position binary dot pattern is then generated for the first and second inks based on the first and second quantity levels. During the mapping, the first quantity level is limited to a value which would result in causing not more than two dots in the four-position binary dot pattern to be generated for the first ink.

摘要： An ink jet printing system having a preheating system for preheating ink during non-printing periods. The system receives print data and commands, feeds paper into the ink jet printer in response to the receipt of print data and commands, detects an ambient temperature within the ink jet printer and determines if the ambient temperature is above a predetermined threshold temperature, preheats the ink supplied to a print head in the ink jet printer during feeding of paper in the case the detected ambient temperature is below the predetermined threshold temperature, moves a printer carriage carrying the print head from a non-printing area to a printing area so as to print the print data. During the moving of the carriage from a non-printing area to a printing area, the ambient temperature is again detected and it is determined again if it is below the predetermined threshold temperature and, in the case that it is, the ink supplied to the print head is preheated during the moving of the printer carriage in the non-printing area.

摘要： A method for controlling printing of pixels corresponding to multi-level image data includes determining, based on multi-level image data for a target pixel and multi-level image data for pixels adjacent to the target pixel, whether the target pixel should be printed using a dye-based ink or whether the target pixel should be printed using a pigment-based ink. In a case that it is determined that the target pixel should be printed using the dye-based ink, a printer is instructed to print the target pixel using the dye-based ink. On the other hand, in a case that it is determined that the target pixel should be printed using the pigment-based ink, the printer is instructed to print the target pixel using the pigment-based ink.

摘要： A printer controller in a printer having at least one detachable print device sends data to a host processor that is representative of the characteristics of a presently attached detachable print device and receives commands from the host processor. In response to the received commands, the printer controller controls a printer function according to the characteristics of the attached print device. The received commands include print head driving parameters corresponding to the characteristics of the attached print device. The print head driving parameters may include parameters that modify values of pre-stored print head driving parameters loaded into the printer at the time of manufacture, or the print head driving parameters may include actual parameter values that are registered for use by the printer during actual printout.

摘要： A paper feed operation is performed by a width less than one pixel (½) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of pixel recording operations are performed for a single pixel region, ink dots land within a distance less than one pixel unit (½). Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.
