Compress Text Objects Option

Check this option to compress the text objects in the output PDF file. This will reduce file size of the PDF.

 

2 . Color Image Compression Color Image Compression

Color Image Compression

Each type of image (Color, Grayscale, and Monochrome) can be compressed in a different way in order to both optimize quality and file size. Images can be compressed in two ways, both of which can be used at the same time.

 

Compressing Images:

To allow compression for a certain type of image (color, grayscale, or monochrome), check the corresponding COMPRESS checkbox.

 

Compressing Images will convert each image to be put in a PDF file, to a more compressed image type. There are several image types which can compress images both with and without loss. JPEG is a lossy format (meaning some quality will be lost), but does a great job of compressing. There are many levels of JPEG compression supported from Maximum to Minimum. The higher the image quality, the less space the image will take up in the file (and hence the smaller the file). Zip (or Flate) compressing is lossless (meaning no quality is lost). However this compression usually does not reduce the image size by very much. Choosing the Automatic setting will let the software determine what is appropriate. This means that usually smaller images will be compressed with less compression (such as Zip/Flate or JPEG Maximum) and larger images will be compressed with more compression (such as JPEG Medium or Low). This is the recommended setting and usually creates very good results.

 

Resampling Images:

To allow images to be resampled for a certain type of image (color, grayscale, or monochrome), check the corresponding RESAMPLE checkbox.

 

Resampling images involves change the dimensions of an image to be smaller so that the image is actually smaller. This means that quality is definitely lost as the DPI has been reduced. The resolution entered will be the new DPI for images which have a DPI higher than it. Images can be resampled in a number of ways. Average Downsample is the faster and lowest quality method of resampling. A Downsample is a slightly slower, but higher quality method. A Bicubic is the slowest, but highest quality. Because the time between these different methods is not very great, we recommend that you use the Bicubic method for resampling.
