As you may know, with all of our standard silk laminated products, we start with 16pt stock as a base and apply 1.5mil soft velvet, scuff resistant laminate to both sides of the sheet for a total thickness of 19pt. But we are the Kings of Custom Printing. If you can think it, we can print it . If you want to silk laminate a thicker cardstock, this will be a custom project and you would need to contact our Support Team to assist in pricing and placing this order. Please make sure to provide as much information as possible for us to be able to get back to you quickly with a detailed response
