Abstract: A width in a first direction of a line in image data corresponding to an image to be printed by a printing apparatus is corrected, based on information on a print result of line-width detection images printed based on line-width detection image data in a raster format that is generated by performing rasterization processing on line-width detection image data in a vector format. In the line-width detection image data in the vector format, a distance between centers of the widths in the first direction of two lines adjacent in the first direction in each line-width detection image is an integral multiple of a rasterization resolution in the rasterization processing.

Abstract: An object is to reduce a difference between a target line width and a width of a line that is printed by a printing apparatus by correcting the line width in accordance with color information indicating a color of the line in a case where an image is printed by the printing apparatus based on image data including the line based on print data. The present disclosure is an image processing apparatus having an acquisition unit configured to acquire a drawing command in which a color and a line width of a line are specified, a determination unit configured to determine a correction amount for correcting the line width specified in the drawing command based on the color of the line specified in the drawing command, and a correction unit configured to correct the line width specified in the drawing command in accordance with the correction amount.

Abstract: Print data for a printing apparatus to print a line-width detection image including first multiple patches is obtained. Each of the first multiple patches includes multiple lines arranged side by side in a first direction, each line having a first width in the first direction and extending in a second direction intersecting the first direction. The distance between the centers in the first direction of two lines adjacent in the first direction of the multiple lines is different from one another. The widths of lines included in an image to be printed by the printing apparatus are corrected based on information on print result of the line-width detection image by the printing apparatus.

Abstract: The present invention provides an antimicrobial agent against Helicobacter pylori, including a material derived from Angelica keiskei. It is preferable that the material derived from Angelica keiskei is a leaf, a stem or a root of Angelica keiskei or a processed product thereof, or sap of Angelica keiskei or a processed product thereof.
