Can tiff images be included/embeded in a PDF, without them being automatically/internally converted to jpeg?
The reason I ask, is becuase I would like to make a PDF for repro but I do not want to use jpegs.
If the answer is 'no' then are there any other ways of providing a PDF for repro, that prints using the tiff originals?
Many thanks for any pointers/help.
Not sure. An easy way to find out is to open a TIFF in Acrobat to create a new PDF. Then go to the tools or advanced menu (in AA9 is Advanced>Document Processing>Export all Images) and see if you get back the original TIFF. You have to select the type and TIFF is there.
'Native' TIFF objects cannot be placed on a page, but you can change the image compression settings in Distiller to use ZIP so the data remains lossless (JPEG2000 is another option but less supported by commercial printers).
By default, monochrome Tiff files are convered to JBIG2 (lossless). Grayscale and Color tiff files are converted to JPEG, medium quality. You can change this in preference panel - Edit>Preferences->Convert to PDF->Tiff->Edit Settings and as Dave suggested, use a lossless format (zip or JPEG2000 lossless) or higher quality JPEG
