This pressing missive comes from Julie:
I saw some killer invitations that were dark purple with white printing. How can I print in white with my inkjet or office laser printer?
DIY Bride Answers:
Though home and office printers have come a long way, none of the ones on the market print in white ink. What you see with most commercially-printed invitations is most likely an inverted printing technique. The designer will create a design with white text on a color background in her layout program. She’ll then print the design on white paper. Because home-office printers can’t print in white, only the background color will print, leaving the text areas open. The wording/design will show as white because there’s no ink on the areas the printer didn’t put color on the white paper. Make sense?
If you truly want white ink on colored paper, you’ll need to do a labor-intensive manual process something like using a rubber stamp, letterpressing or screen printing where an opaque white ink is spread onto a stamp, plate or screen (respectively) and then applied directly to the paper. And, for what it’s worth: getting a solid, opaque white ink is notoriously hard. Be prepared for lots of experimentation and extra printing!
