Producing designs in white ink is only available through one of two specialty processes: Screen Printing (also known as silk screening) or Foil Stamping.
We are able to print CMYK ink over top of screen printed designs, but the opposite process is not available - we cannot produce a screen printed design directly over top of CMYK printed artwork. This is due to application issues where the screen printed design does not adhere properly when placed over ink (it needs to be produced directly on the stock material).
One solution to this issue is to use a Matte Foil (available in many colours, including white) instead of a screen print method. We can foil stamp over top of printed artwork.
Another option is to have a laminate coating applied overtop of the printed stock, then have a screen printed design produced over top. Adding a laminate coating over the stock will change the texture / feel of the card. Available laminate coatings are: Silk Matte Laminate, Super Gloss Laminate.
This would be a custom order that would need to be submitted as a Print Quote request.
If printed artwork is needed around/ beside the white (or other screen printed colour) a 1/16" safe margin around the screen printed element is needed. Slight shifting between the two processes in any direction would be expected, meaning there will be a risk of printing slightly over the white artwork if they are close together.
