Send your artwork to us "camera ready," meaning that it is in black ink on clean, unlined white paper or posterboard. You can also e-mail the artwork to us. Since your costs are determined by the total number of square inches submitted, place your designs close together. You only need to leave enough room between designs to cut them apart. Determine the total to the nearest image size; for example, an image area measuring 7 1/4" x 9 1/2" = 68 7/8 square inches and will be considered as a 70 square inch area. RUBBER DIES are the printing portion of the stamp. We form them from your Matrix Mold. We'll gladly hold your engraving and matrix on file, then mold rubber sheets of your images whenever you need them. Once received, you can mount them on cushion and your choice of stamp mount. Three price categories apply as determined by the depth of the image. Minimum charge is 20 square inches.
