Sirio Ultra Black Flat Cards

To assist you in finding paper that best suits your application, we offer paper samples for color matching and testing with your specific application, and recommend testing prior to purchasing your paper.

Printing: Cardstock Warehouse provides best practice recommendations for printing and other applications based on our in-house testing and specifications provided by the manufacturing paper mills. The majority of our papers are suitable for conventional printing and processing methods, however, when it comes to paper compatibility with printing and other applications, we cannot explicitly guarantee outcomes. This is due to the diverse range of consumer and professional printers and other processing equipment, each with its unique mechanical and technical characteristics. Additionally, different inks, adhesives and other processing techniques can yield varying results when used on different paper types. If you plan to utilize the services of a professional, we recommend consulting with them to address your specific needs.

Color: While we take great care to accurately photograph product colors, device screens and monitors may not display true to color; photographs are meant to be used only as a guide. When color matters, we recommend purchasing samples prior to purchasing a larger quantity.

Cardstock Warehouse Paper Co, Inc. assumes no liability for any incidental or consequential damages or losses that may occur, whether they are related to color, printing, other applications, or information provided, regardless of whether provided verbally, in writing, or on this website. Ultimately, the responsibility for the outcome lies solely with the consumer.
