The standard resolution of photos taken with digital photo cameras is 75 DPI. If you want high quality prints of photos or other images (high precision, good color transfer and low grain), you should use a printer with resolution of 300 or more DPI. However, if DPI of the photo differs from printing DPI, you’ll have to adjust printing parameters for every image. If there are many images, such preparations will take much time. Still, you can change DPI of all images to make it same with your printer DPI and print photos without specifying additional settings. The same should be done to prepare images for printing in photolabs, where 300 DPI is the standard resolution value. Image Converter Plus will help change image DPI automatically.
Do the following:
- Launch Image Converter Plus.
- Go to “Photos” tab, select and add photos you want to convert.
- Go to Profiles tab. In “Operation before save: Add operation” line, click “Add operation” and select “Resize” from the menu.
- Click “+” mark located to the left from “Add operation” line to open the group of settings for added operations.
- In “Resize”, set the value of “Pixel Dimensions” to 0x0.
- Press “more” button and enter the supposed horizontal printing resolution in “Horizontal Resolution” line (in our case it will be 300 DPI).
- If vertical printing resolution coincides with horizontal one, enable “Use as Horizontal” checkbox. Otherwise, disable this checkbox and enter vertical printing resolution into “Vertical Resolution” line.
- Disable “Use original image resolution, in case it is supported” checkbox.
- Specify output format settings (optimal values are specified by default).
- Specify the folder to save converted images to.
- Specify other settings.
- Press “Start” button to start conversion.
