I had been printing out an Illustrator file fine directly through Illustrator. However I recently saved the file as a PDF in preparation to send it to the printers. I opened the PDF in Adobe Reader and printed it out, but what was printed out was significantly darker than what I got when printing from Illustrator. I opened the original Illustrator .ai file in Reader and when I printed that it came out much darker as well.
I tried printing the PDF directly through Illustrator again and the colors were fine. The problem is I need to be able to print the PDF properly using Reader as the printers I'm sending the PDF to don't use Illustrator for their printing.
The only success I have had so far is by saving the Illustrator file as a PDF using File-Print-Printer-Save as PDF. When I print this PDF through Reader the colors are great but the image is flattened (i.e. the text isn't selectable or vectorized) that surely cannot be a good thing? I read this http://www.carijansen.com/tips/024/index.php that also firmly discouraged this way of saving PDFs.
