Postcards are a great source to reach new customers and stay in touch with existing ones. Available in a variety of different sizes, postcards are printed on premium quality extra heavy card stock with high gloss finish on the printed sides. Choose from full color printing with high gloss finish on one side and a semi-gloss finish on the non printed side or full color printing with high gloss finish on both sides. Please note that the high gloss finish is a non-ink-receptive surface which makes writing or printing on the finished postcard difficult.Upload Files: You will be uploading your file(s) during checkout, After we receive your uploaded file(s), we will review each file.
