When you want to print an image from Photoshop, there are a few things you need to do in order to ensure that the image prints correctly. First, you need to make sure that the image is in the correct color mode. For printing, CMYK is the best color mode to use. You can convert an image to CMYK by going to Image > Mode > CMYK Color.
Once the image is in the correct color mode, you need to adjust the resolution. The resolution should be set to at least 300 pixels per inch, but 400 or 600 pixels per inch is even better.
To change the resolution, go to Image > Image Size. In the dialog box that opens, make sure that the “Resample Image” checkbox is unchecked and then change the Resolution to 300 or higher.
The last thing you need to do before printing is to make sure that all of the important parts of your image are within the safe print area. The safe print area is a margin around the edge of your image where ink can bleed without ruining the rest of your print. To check the safe print area, go to File > Print and then click on “Page Setup”. In the dialog box that opens, make sure that “Safe margins” is checked and then click “OK”.
After following these steps, your image should be ready to print from Photoshop!
