Tips and best practices

These general guidelines about creating and managing images and other color resources can improve the performance of your AFP color printing system.

Tips for images

To optimize the performance of your AFP color printing system, you should follow some guidelines for creating and including images in print jobs.

When you want to use color images in your print jobs:

  • Get the original electronic versions of images instead of scanning existing documents.

    Almost unnoticeable specks of color in the background of images that have been scanned can greatly increase the size of the image. If you must scan an image, use an image editing tool to clean up the background as much as possible.

  • Save all images in the same standard color space so you only need one input profile for all of them.

    Adobe RGB (1998) is the recommended color space for images that are to be printed.

  • Flatten multi-layer images (such as the ones you can create in graphics tools like Adobe Illustrator and Corel Paint Shop Pro) before including them in print jobs.

    Unflattened images are extremely large and more difficult to work with. Save a copy of the original image for future editing, but flatten the version that you include in your print job.

Tips for resources

To optimize the performance of your AFP color printing system, you should follow some guidelines for managing color resources.

You can use AFP Resource Installer to:

  • Install all the CMRs for your printer in a resource library.
  • Install the data objects that you use frequently in a resource library.
  • Mark the CMRs and data objects that are reused regularly as non-private, capturable resources so they can be saved on the printer and used for other print jobs without being downloaded every time.
    Note:
    This option is not advisable for secure resources, such as signature files.
  • Install CMRs and data objects in resource libraries that the print server can access, so they only need to be stored in one place and can be used by all print servers.
  • Associate audit color conversion CMRs with data objects that require color management, so the embedded profiles can be removed from the image files.
