Specialties Petersen Specialty / Leyba's is a local family owned business that creates custom rubber and self-inking stamps, notary and professional seals and engraved signs. We also specialize in ADA signage which is commonly used in all types of buildings to help give direction to people who are handicapped, blind or vision impaired. Another great process we use called sublimation is used to imprint full color photos, logos and other images on a variety of items including nametags, signs, t-shirts, mousepads and much more. For small companies this is great way for branding your products and services without a huge cost and large quantities that you might run into with other promotional products. It's also a fun and unique way to be able to present someone with a unique gift or to commemorate a special occasion.
