It is a tool to mutually convert the print size of an image and the number of pixels. It helps to determine whether a date can be used as a publication or commercial print. When you want to know the number of pixels required for the planed range of the printing, the print size from the number of pixels of an image and the print size from an image size displayed on a screen, this tool will be useful. It can also convert a paper size to the number of pixels. How to use: first, you need to register print types such as color printing and gray printing and the corresponding printing resolution. Then this tool works according to the print type. It can also take the zoom ratio into account when you arrange an image to DTP software, etc. In addition, it will be useful at the production scene of Responsive Web site. For example, you can know with this tool how many millimeters of arbitrary pixels are displayed on a screen. Conversion function Convert mutually pixel values to mm, cm, point, inch and pica Convert an image size on a screen to the print size Convert a paper size to the pixel values Display of conversion result The pixel value (the minimum value) are displayed as an integer rounded up to the nearest decimal point The converted values (the maximum value) are rounded down to the second decimal place or the third place depending on the unit, e.g. mm Customize Registerable print DPI: 3 types.
