PDF Proof
> >
A PDF proof is an electronic file for a client to approve or make comments on. PDF stands for Portable Document File, a printing file format that we use for printing purposes. PDF is the industry-standard format for a client supplying a job to a printing company. It is also used for the printing company to prove back to the client. A PDF proof can be opened on most electronic devices, from a mobile phone to a monitor. This enables a client to view and check a PDF anywhere in effect. It also means the PDF proof can be circulated to more than one person for checking and comment.

PDF proofing saves time and money if used correctly.

How Is a PDF Proof Created?

Pre-press systems in printing companies process the high-resolution PDF files supplied by the client. These are then checked for common errors. This is called pre-flighting. The final PDF files for printing are then scaled down to a lower resolution version. This PDF proof can be emailed or messaged to the client for approval or comment. This ensures the integrity of the proof file is the same as the print file. As only an electronic process has taken place so far, any corrections needed are easier and cheaper to do.

What Can Be Checked on a PDF File?

The artwork we use for printing is in high-resolution PDF format. After we receive the printing files from our client, our designer will check for the following pitfalls:
  • The artwork has the correct amount of bleed.
  • The images are the correct resolution.
  • The texts are not too close to the trim or fold edge.
  • Small size texts are not set up as CMYK.
  • Any solid black background is not set up as purely 100% black.
  • The artwork size and the order size are as specified.
We also:
  • Remove all embedded ICC profiles
  • Check the fonts are embedded
  • Flatten all transparency
  • Convert all colors (RGB or Pantone) to CMYK if the job is to be printed full color
  • Measure the spine thickness and ensure the text and images on the spine match the spine thickness
  • Ensure the hardcover binding book has enough wrapping space on the cover artwork
  • Make sure the foil stamping, spot UV, embossing and debossing artwork are vector graphics or vector texts.
