I recently completed a project in Illustrator Cs4 and sent my .ai file to the printing company (Disc Makers). When the printer sent me a .pdf proof I noticed some anomalies in the text, all instances of the letters “L” and “I” appear thicker and somewhat distorted. They also sent me a .jpg proof as well and it looks perfect. I was worried that perhaps there was an issue with my .ai file so I went ahead and created my own press quality .pdf file, it looked fine. I am not sure if it matters, the text was copied and pasted from a Word document into Illustrator, also I am on a PC and the print company uses Mac. I am concerned because the printer uses the pdf file to print. I am new to Illustrator so I am hoping it’s not something on my end. Has anyone else run it to this?
