Screen Printing Tip of the Week: Using Puff Ink

September 11, 2013

Puff ink, which has been around since the early 1970s, is making a comeback. One of the original “special effects” inks, puff expands during the curing/heating process, adding a 3-D texture to prints.

Here are a couple of tips for using puff ink:
•    By using a thicker stencil, such as a capillary film, to print the puff design, you can achieve a higher loft without having to print-flash-print too many times.
•    When printing a larger design with puff, creating a fat or coarse half-tone design — rather than one big area — will allow the ink to expand without distorting the overall design. When too much puff ink is printed as a large area, the expanding ink tends to cross over the original borders of the design.
