Print production refers either to digital printing, such as color lasers, or to commercial printing, such as offset lithography. Digital printing typically only requires about 120 ppi for good print quality. Also, most digital printers have engines built in to convert RGB color to CMYK. Commercial printing requires a much higher file resolution, and RGB images may need to be converted to CMYK or grayscale. The minimum resolution is typically 300 ppi at 100% size. You should, however, always check with your service provider for file requirements. To achieve the best print quality, images should not be artificially scaled up in Photoshop by more than 110% of their original size. It's also important to note that Photoshop should not be used for adding a lot of text. Because Photoshop files are bitmaps, small, body-weight text will appear fuzzy. Text should be limited to large display text only. Smaller text should be added to the imported Photoshop image with a page layout program, such as InDesign.
This feature works the same in all recent versions of Adobe Photoshop: CS5, CS6, and Creative Cloud (CC).
