The letterpress can elevate your projects to another level, but not everything can be letterpressed. Here’s a few things to consider when designing.
Letterpress plates type and design specifications can vary between the shops that create them, but typically they’ll want a vector illustration, such as an InDesign or Illustrator file, to create a polymer plate. If you use any type in your design, you’ll want to outline the text to maintain your design.
Typically, platemakers want type no smaller than 6 points and lines at least .25 point (.0035 inch). The plates are raised polymer used to create a relief. If your design is too small or too thin, they will not hold up in the platemaking process.
Letterpress ink is translucent, therefore floods of color need to be carefully considered. The paper will show through on large floods, giving it a textured, almost suede appearance. This gives a beautiful vintage quality, but you need to be sure it’s what you want. Also, large solid fills will not leave as deep or crisp an impression on the paper as a smaller area.
Designing for multiple colors? You’ll need to consider the registration. Open, spacious designs make for a simple registration, but tighter designs, where colors are overlapping or touching, make for a more complex registration. Whatever the complexity, always include registration marks in a multicolor design. (For the simpler ones, you can even just use the crop marks as registration marks.)
One-Sided or Two?
Though one-sided printing is the ideal, two-sided letterpress printing is possible. The biggest concern in two-sided printing is bruising, or the impression from one side showing on the reverse. This issue can be minimized by choosing a thicker stock or reducing the pressure, if the job allows for it.
As previously mentioned, letterpress ink is translucent so it’s recommended to use dark ink on a light stock. Therefore, reverse type, or printing a light color on a dark background, is also very tricky on the letterpress. Most colors won’t show very well on a dark stock, so you’ll achieve more of a deboss than print. There’s also the option of making it a double-pass (printing it twice), but that risks ruining the crisp indents the letterpress creates on the first pass.
