Supplying artwork

  1. Print ready PDF files should be sent (please make sure to include bleed and crop marks).
  2. On receipt we will flightcheck files to ensure they are print quality (ie all fonts outlined and/or embedded; CMYK colour space; colour bitmap images at 300dpi resolution; greyscale bitmap images at 300dpi resolution; monochrome bitmap images (linework) at 1200dpi resolution).


  1. The file content of electronic supplied artwork is the responsiblity of the originator.
  2. The creator should apply any required trapping (regarding overprint and knockout), as it cannot be applied during production. Specific trapping requirements should be highlighted prior to supply.
  3. All electronically supplied advertisements should be accompanied by a proof. If this is faxed or sent in black and white GTI can only accept responsibility for checking content. Only colour contract proofs can be used for checking exact colour.
  4. Please note we have specified pass4press settings. On arrival at GTI, all PDFs will be checked through Pit Stop, creating a report of how the file has been supplied. If the file has not been created as we specified this may correct some errors; however it is the responsibility of the creator to ensure the Distiller options are set correctly.
  5. GTI will produce artwork for clients should they require this service. Prices will vary according to content.
