Ho w to Prep a photo for a large print

Set pixel size in Photoshop

Choose Image > Image Size, set Width and Height to Pixels, and set the number of pixels this needs to be. Alternatively, set the physical size your print needs to be, then set resolution to the pixels-per-inch value you’ve calculated.

Use ON1 Resize

The Document Size pane can be used to set an image’s dimensions and pixel resolution manually; a pop-up menu of suggestions is provided as an aid. Alternatively, pick a printer and paper type from the presets on the left.

Resize in Preview

Open your image in Preview and choose Tools > Adjust Size. Next, either set the overall pixel dimensions you need, or use the dropdown on the right to set the physical width and height, and the pixel resolution, then click OK to scale the image smoothly.

Set interpolation method

In the Resample pop-up menu, choose an interpolation method. We recommend “Preserve Details (enlargement)” for most images, but test the available choices to see which you prefer for your image.

Tricks for ON1 Resize

The big benefit of ON1 Resize is its bag of print-related tricks. Here, the Gallery Wrap feature mirrors the edges of the image to create a print that’s suitable for wrapping around the sides of a frame.

Sharpen in Preview

To sharpen the results of resizing your image, simply choose Tools > Adjust Color from the menu bar and drag the Sharpness slider to the right. Try setting it from the three-quarters point onwards. (Dragging the slider to the left actually blurs your image.)
