PDF processing

An overview of the PDF processing available in a channel.

PDF processing

Where: Channel | Input File Formats | Adobe PDF tab

By default, Color Factory moves PDF files directly to the UNKNOWN folder. However, you may choose to process PDF files, allowing in-place color management and optional conversion to postscript.

 

Page splitting

After enabling PDF processing, you may choose to split the PDF file so that each page in the file is extracted and stored as a separate PDF file. By clicking the Set split options button you can set file naming conventions. You can either add a suffix to the file name as in the example screenshot above, or you can make Color Factory look for a number in the original file name and update the number according to each page’s number. (The Update existing page number in file name option.)

Image conversion

If you enable Do in-place color management and image processing you may set options pertaining to the type of PDF information that should be processed, with separate processing of text and graphic elements (see above screenshot).
For images you can choose the JPEG compression to use, and you may even disable JPEG compression altogether to retain maximum quality.

Embed ICC profile with objects: Enabling this option will make Color Factory embed the ICC profile in every graphic element inside the PDF.

Use Black Point compensation: Tick this box to enable black point compensation when converting between color spaces.

Postscript/EPS conversion

If you choose to Convert PDF to Postscript/EPS, a number of conversion options are available by clicking Set conversion options, as seen above. Rather than process the PDF file, you may choose simply to extract the visual information from the files and render bitmaps. This is done by choosing Render a bitmap of the PDF page. These bitmaps will then be stored in the channel’s output folder in the format specified on the Channel Settings page.

Further, you may choose to extract the images contained within the PDF documents for processing in the channel. They will then be processed according to the channel's settings and stored in the format specified in the channel settings.

Finally, you may choose to copy the original PDF input file to the output folder, using all enabled channel features not involving manipulation of image data. Hence, files may be routed, captioned (as the caption is stored in a sidecar file), and renamed according to the channel’s settings.

Important - timeouts during processing
When processing a PDF file, Color Factory has a timeout count of 4 minutes or maximum 5000 objects. When the timeout is reached or the number of objects in the PDF exceeds 5000, the document will be converted using a faster method without channel processing. The timeout has been introduced to avoid blocking the server's processing entirely when complex PDF's are handled in the queue. Color conversion will always be done according to channel settings, but additional channel processing such as sharpening will not be applied.
