Q: Can your blank postcards (Single On Demand) be printed on both sides? If yes, are the Glossy ones that can only be used with a laser-printer glossy on both sides or matte on the reverse side?
A: Yes, our Print-On-Demand Single Postcards™ can be printed on both sides. The 4x6G (laser gloss) is a high gloss finish on one side and matte on the reverse. This product is for laser printers only. If you have an inkjet printer, we recommend only using paper specifically designated as inkjet paper, as it will absorb the ink properly. Here are some examples of our products, which are only designated for inkjet printers.
