You could elect to choose ‘No proof required’ if you have supplied a PDF file which you have printed out and checked carefully, and which conforms to our requirements (images are high resolution, images are converted to CMYK, and bleeds have been allowed for if the job prints to the edge of the paper).
There is little point in sending you a PDF proof of a properly supplied PDF file, as we will most likely be sending your file back to you as a proof.
You might elect to choose ‘No proof required’ to speed up the production process provided your job has been supplied as a conforming PDF file (see above). You will probably save a day in the production process.
