Photoshop printing

Whether you are printing an image to your desktop printer or sending it to a prepress facility, knowing a few basics about printing makes the print job go more smoothly and helps ensure that the finished image appears as intended.
Types of printing
For many Photoshop users, printing a file means sending the image to an inkjet printer. Photoshop can send your image to a variety of devices to be printed directly onto paper or converted to a positive or negative image on film. In the latter case, you can use the film to create a master plate for printing by a mechanical press.

 

Types of images
The simplest images, such as line art, use only one color in one level of gray. A more complex image, such as a photograph, has varying color tones. This type of image is known as a continuous-tone image.

 

Color separation
Artwork intended for commercial reproduction and containing more than one color must be printed on separate master plates, one for each color. This process, called color separation, generally calls for the use of cyan, yellow, magenta, and black (CMYK) inks. In Photoshop, you can adjust how the various plates are generated.

 

Quality of detail
The detail in a printed image depends on image resolution (pixels per inch) and printer resolution (dots per inch). Most PostScript laser printers have a resolution of 600 dpi, while PostScript imagesetters have a resolution of 1200 dpi or higher. Inkjet printers produce a microscopic spray of ink, not actual dots, resulting in an approximate resolution of 300 to 720 dpi.

About desktop printing

Unless you work in a commercial printing company or service bureau, you probably print images to a desktop printer, such as an inkjet, dye sublimation, or laser printer, not to an imagesetter. Photoshop lets you control how your image is printed.

Monitors display images using light, whereas desktop printers reproduce images using inks, dyes, or pigments. For this reason, a desktop printer can’t reproduce all the colors displayed on a monitor. However, by incorporating certain procedures (such as a color management system) into your workflow, you can achieve predictable results when printing your images to a desktop printer. Keep these considerations in mind when working with an image you intend to print:

Print images

Photoshop provides the following printing commands:
Print
Displays the Print dialog box, where you can preview the print and set options. (Customized settings are saved as new defaults when you click Done or Print.)

 

Print One Copy
Prints one copy of a file without displaying a dialog box.

 

For maximum efficiency, you can include the Print command in actions. (Photoshop provides all print settings in one dialog box.)

Set Photoshop print options and print

  1. Choose File > Print.
     
    Print dialog box
    A.
    Preview print

     

    B.
    Set printer and print job options

     

    C.
    Set paper orientation

     

    D.
    Position and scale image

     

    E.
    Specify prepress output options

     

    F.
    Specify color management and proofing options

     

  2. Select the printer, number of copies, and paper orientation.
    In Mac OS, send 16-bit data to the printer to produce the highest possible quality in subtle graduated tones, such as bright skies.
  3. Adjust the position and scale of the image in relation to the selected paper size and orientation.
  4. Set Color Management and Output options, which you access from the pop-up menu in the upper-right corner.
  5. Do one of the following:
    • To print the image, click Print.
    • To close the dialog box without saving the options, click Cancel.
    • To preserve the options and close the dialog box, click Done.
    Note: If you get a warning that your image is larger than the printable area of the paper, click Cancel, choose File > Print, and select the Scale To Fit Media box. To make changes to your paper size and layout, click Print Settings, and attempt to print the file again.

Set printer options

  1. In the Print dialog box, click Print Settings.
  2. Set paper size, source, and page orientation as desired.

    The available options depend on your printer, printer drivers, and operating system.

 

Let printer determine printed colors

If you don’t have a custom profile for your printer and paper type, you can let the printer driver handle the color conversion.
  1. Choose File > Print.
  2. Choose Color Management from the pop-up menu in the upper-right corner.

     

    Choose Color Management to display additional options.

     

  3. Select Document.

    The profile is displayed in parentheses on the same line.

  4. For Color Handling, choose Printer Manages Colors.
  5. (Optional) Choose a rendering intent for converting colors to the destination color space.

    Many non-PostScript printer drivers ignore this option and use the Perceptual rendering intent.

  6. Access the color management options for the printer driver from the Print Settings dialog box, which automatically appears after you click Print. In Windows, click Print Settings to access the printer driver options. In Mac OS, use the pop-up menu from the Print Settings dialog box to access the printer driver options.
  7. Specify the color management settings to let your printer driver handle the color management during printing.

    Every printer driver has different color management options. If it’s not clear how to turn on color management, consult your printer documentation.

  8. Click Print.
    Note: If you get a warning that your image is larger than the printable area of the paper, and you don’t want to exceed that area, click Cancel, choose File > Print, and select the Scale To Fit Media box. To make changes to your paper size and layout, click Print Settings, and attempt to print the file again.

Let Photoshop determine printed colors

If you have a custom color profile for a specific printer, ink, and paper combination, letting Photoshop manage colors may produce better results than letting the printer manage colors.
  1. Choose File > Print.
  2. Choose Color Management from the pop-up menu.
  3. For Color Handling, choose Photoshop Manages Colors.
  4. For Printer Profile, select the profile that best matches your output device and paper type. If there are any profiles associated with the current printer, they are placed at the top of the menu, with the default profile selected.

    The more accurately the profile describes the behavior of the output device and printing conditions (such as paper type), the more accurately the color management system can translate the numeric values of the actual colors in a document.

  5. (Optional) Set any of the following options.
    Rendering Intent
    Specifies how Photoshop converts colors to the destination color space.

     

    Black Point Compensation
    Preserves the shadow detail in the image by simulating the full dynamic range of the output device.

     

    Match Print Colors
    Enabled when you let Photoshop manage color. Select to view image colors in the preview area as they will actually print.

     

    Gamut Warning
    Enabled when Match Print Colors is selected. Select to highlight out-of-gamut colors in the image, as determined by the selected printer profile. A gamut is the range of colors that a color system can display or print. A color that can be displayed in RGB may be out of gamut for your current printer profile.

     

    Show Paper White
    Sets the color white in the preview to the color of the paper in the selected printer profile. This produces a more accurate print preview if you're printing on off-white paper such as newsprint or art papers that are more beige than white. Since absolute white and black create contrast, less white in the paper will lower the overall contrast of your image. Off-white paper can also change the overall color cast of the image, so yellows printed on beige paper may appear more brown.

     

  6. Access the color management options for the printer driver from the Print Settings dialog box, which automatically appears after you click Print. In Windows, click the Preferences button to access the printer driver options. In Mac OS, use the pop-up menu from the Print Settings dialog box to access the printer driver options.
  7. Turn off color management for the printer, so the printer profile settings won’t override your profile settings.

    Every printer driver has different color management options. If it’s not clear how to turn off color management, consult your printer documentation.

  8. Click Print.
    Note: If you get a warning that your image is larger than the printable area of the paper, click Cancel, choose File > Print, and select the Scale To Fit Media box. To make changes to your paper size and layout, click Print Settings, and attempt to print the file again.
