The inkjet printing apparatus is configured to be able to execute a batch adjustment process of performing a plurality of times of adjustment processes related to printing in succession based on one instruction from an outside. The conveyance control unit maintains the conveyance speed at a first speed in a period when a chart printing process is performed and a period when a chart imaging process is performed. The conveyance control unit decreases the conveyance speed from the first speed to the second speed after the end of the chart imaging process in an adjustment process except for an adjustment process that is performed last in the batch adjustment process, and increases the conveyance speed from the second speed to the first speed before the start of the chart printing process in an adjustment process that is performed next.

First relational equations which represent characteristics of respective sample colors are obtained, and for the respective sample colors, prediction values of spectral characteristics of characteristics-acquired gradation values for a prediction target color are obtained using the first relational equations. Difference values between the prediction values and actual measurement values are obtained, and a sample color for which a minimum difference value is obtained is selected as a reference color. A second relational equation that represents characteristics of the reference color is obtained, and a prediction value of spectral characteristics of a prediction target gradation value for the prediction target color is obtained using the second relational equation.

First, a color close to a prediction target color is selected as a first similar color from among a plurality of similar candidate colors. Next, a first relational expression representing a relationship of spectral reflectances of a solid patch between a reference medium and a prediction target medium is obtained for the first similar color. Then, spectral reflectances of the solid patch in the prediction target medium for the prediction target color are predicted by applying spectral reflectances of a solid patch in the reference medium for the prediction target color to the first relational expression. Finally, spectral reflectances of each halftone patch in the prediction target medium for the prediction target color are predicted based on the prediction result.

First, a color close to a prediction target color is selected as a similar color from among a plurality of sample colors for which spectral reflectances of a plurality of patches are obtained. Next, for a similar color, a relational equation representing the relationship between the spectral reflectances of a solid patch (a patch with the highest ink density) and the spectral reflectances of a color prediction target patch is obtained. Finally, the spectral reflectances of the solid patch for the prediction target color are applied to the relational equation, by which predicted values of spectral reflectances of the color prediction target patch for the prediction target color are obtained.

In a print control device, a page data correction portionreceives page data Dpg included in manuscript data Dd and, when the page data Dpg includes a predetermined type of barcode font with a data resolution different from a print resolution, corrects font data within barcode data while maintaining a barcode length, such that any bars and spaces included in a character represented by the barcode font have widths corresponding to natural numbers of pixels with a resolution that is a natural number multiple of the print resolution. A rasterization processing portionrasterizes corrected page data with a high resolution and thereafter anti-aliases the rasterized page data, thereby generating print-resolution raster data Drs.

A first flash heating is performed in which a flash lamp emits a first flashing light to a semiconductor wafer having been heated to a first preheating temperature equal to or lower than 650 degrees C. by a light emission from a halogen lamp so that the temperature of a surface of the semiconductor wafer reaches 1000 degrees C. or higher. Then, a second flash heating is performed in which a second flashing light is emitted to the semiconductor wafer having been further heated by a light emission of the halogen lamp. Performing the first flash heating can suppress diffusion of impurity in the subsequent second flash heating. In the second flash heating, the impurity is activated and introduced crystal defects are recovered.

First irradiation which causes an emission output from a flash lamp to reach its maximum value over a time period in the range of 1 to 20 milliseconds is performed to increase the temperature of a front surface of a semiconductor wafer from a preheating temperature to a target temperature for a time period in the range of 1 to 20 milliseconds. This achieves the activation of the impurities. Subsequently, second irradiation which gradually decreases the emission output from the maximum value over a time period in the range of 3 to 50 milliseconds is performed to maintain the temperature of the front surface within a &#xb1;25&#xb0; C. range around the target temperature for a time period in the range of 3 to 50 milliseconds. This prevents the occurrence of process-induced damage while suppressing the diffusion of the impurities.

On the basis of a first calibration point corresponding to a reflectance of a state where a target ink or the like is applied on a transparent ink and a second calibration point corresponding to a reflectance of a state where the target ink is applied on a black ink that is applied on a base material, a third calibration point corresponding to a reflectance of a state where the target ink is solidly applied on a background having an average reflectance is obtained. A reflectance as a prediction value of a color corresponding to the reflectance of the entire background is obtained on the basis of the third calibration point and a fourth calibration point corresponding to a reflectance of a state where the target ink is applied on the base material.

Flash lamps connected to short-pulse circuits and flash lamps connected to long-pulse circuits are alternately arranged in a line. The duration of light emission from the flash lamps connected to the long-pulse circuits is longer than the duration of light emission from the flash lamps connected to the short-pulse circuits. A superimposing of a flash of light with a high peak intensity from the flash lamps that emit light for a short time and a flash of light with a gentle peak from the flash lamps that emit light for a long time can increase the temperature of even a deep portion of a substrate to an activation temperature or more without heating a shallow portion near the substrate surface more than necessary. This achieves the activation of deep junctions without causing substrate warpage or cracking.

Rip time estimation method

A white-plate graphic erosion process is performed on print data subjected to a RIP process in the following procedure. First, an erosion candidate region which is a candidate for a region in which a white-plate graphic is eroded is determined. Then, a region to be applied with an ink of a color other than white is determined. Then, an application target region is determined. Then, a region other than a region obtained by an erosion process out of the application target region is determined to be an erosion allowed region. Then, a region included in the colored region and the erosion allowed region out of the erosion candidate region is determined to be an erosion target region. Finally, the values of data of pixels included in the erosion target region among white-plate data are rewritten such that the amount of white ink applied to the pixels is reduced.

A susceptor that holds a semiconductor wafer placed thereon is capable of moving up and down inside a chamber. For preheating with a halogen lamp, the susceptor moves to a preheating position. The preheating position is a height of the susceptor that achieves the most uniform in-plane illumination distribution of light emitted from the halogen lamp and applied to the semiconductor wafer. After the preheating is finished, the susceptor moves to a flash heating position for irradiation with a flash from a flash lamp. The flash heating position is a height of the susceptor that achieves the most uniform in-plane illumination distribution of a flash emitted from the flash lamp and applied to the semiconductor wafer.
