All of our cardstock is printed on high-quality, digital printers in 4-color process (CMYK). When the quantities and design call for it, these may be offset-printed.
We employ a proprietary printing system to produce excellent reproduction fidelity while preserving our high germination standards. Maintaining these standards can influence your options when designing for seed paper (please see Art Guidelines). Printing on our seed paper employs a proprietary inkjet system. By "spraying" the ink onto the seed paper, we achieve the highest print quality and preserve our high germination standards. For these same reasons, we require that your custom design has light ink coverage (no large solid areas, background images, etc.) although your art can include full-color graphics, logos, and text. When in doubt, please submit your art for approval or guidance. Often a few little changes can make a big difference.
Second-side inkjet printing: Because of the handmade nature of our seed paper, it is difficult to have perfect registration from front to back. Typically, minor adjustments to the art can make any registration shortcoming less noticeable.
We operate several vintage letterpress machines that “stamp,” or deboss, your design into the seed paper. Letterpress can be debossed only, or debossed and printed with up to two colors. This process does not significantly decrease germination rates. Letterpress is a wonderful complement to our colorful and richly-textured seed paper.
In addition to printing cardstock with offset printers, we can print seed paper using this method as a last option. We have lab-tested paper printed with this method, determining that the heavy pressure of the press crushes many of the seeds and renders them sterile. We prefer to only produce printed seed paper products that meet our high germination standards. Offset-printed seed paper will not grow when planted, but can still communicate your green message if your project is high-volume, fast-turn, or low-budget. We will always disclose the harmful effects of offset printing and let you decide.
