Guidelines for Format

and Compression

In editing or creating a new profile it is necessary to specify the

format and compression techniques that are to be employed. The

table below highlights the significant benefits of each method.

Notes:

Format Comments

TIFF For color, black/white and grayscale images. Both single- and multipage

images are supported

JFIF For color and grayscale images. Single page images only.

PDF For black/white, color and grayscale images. Both single- and multipage

images are supported. Requires the Adobe Acrobat Reader.

PCL Profile used for print destinations - black and white only.

• Compression techniques are distinguished by whether they remove detail

from the image or not. CCITT encoding is a family of lossless compression

techniques for black/white images, of which CCIT G.4 is the most effi-

cient compression method.

• JPEG is a compression technique that effectively reduces file size by iden-

tifying and discarding extra data not essential to the display of the

image.

• If you intend to manipulate a color image using an image editor, you are

recommended to use uncompressed TIFF.

• Although the generated TIFF files do not contain searchable text, you can

use an Optical Character Recognition (OCR) application to convert the

bitmap to text that can be edited, indexed, searched or copied to other

files.
