Files shoud be high resolution PDF, in CMYK colour mode, with images set at 300 dpi at 100% size.


Overprinting refers to the process of printing one colour on top of another. In most cases you will want to make sure that overprint options are turned off in your layout program and switched to knockout. Below, the file was not switched to overprint, and even though the white text is showed on screen, when printed, the text did not show up due to overprint issues.

Please note that our file preview does not display overprint problems, so it is important to check your file for overprint issues before uploading the file to us.


Transparency effects sometimes causes ripping (file processing) problems when used over top a spot colour (such as a PMS - Pantone Matching System colour) and will cause graphic elements to disappear. To prevent this, do not use any shadow, glows and transparency on top of a spot colour – always convert your spot colour to CMYK.

We require 100% K (black) only for black text (C0, M0, Y0, K100). Rich blacks or any other dark colour should not be used for small type or thin lines because it will likely  create registration issues and produce type that looks blurry.
