Abstract
A calibration capability is implemented in a printer itself without using a scanner or an intensity level meter thereby achieving high color reproducibility. The calibration capability is realized by means including chart outputting means for outputting a chart used to determine an intensity level correction parameter of a printer, inputting means for inputting the parameter determined from the chart, table generation means for generating a table used to correct the intensity level of the printer in accordance with the input parameter, and intensity level correction means for correcting the intensity level of the printer using the table, thereby making it possible to visually correct the intensity level of the printer.
