What commercially available printing process allows for printing on 450gsm matte cardstock?
There are several commercially available printing processes that can be used to print on 450gsm matte cardstock. Here are some of the most common printing processes that can handle this type of stock:

1. Offset Printing: This is a traditional printing method that uses metal plates to transfer an image to paper. Offset printing can handle a wide variety of paper stocks, including thick cardstock, making it a popular choice for high-quality printed materials.

2. Digital Printing: This is a newer printing method that uses digital technology to transfer an image to paper. Digital printing is a more cost-effective option for shorter print runs and can handle a range of paper stocks, including thick cardstock.

3. Letterpress Printing: This is a printing method that uses a raised plate to press an image onto paper. Letterpress printing can produce high-quality, tactile prints on thick cardstock, making it a popular choice for business cards, invitations, and other high-end printed materials.

4. Screen Printing: This is a printing method that uses a stencil and mesh screen to transfer ink onto paper. Screen printing is often used for printing on thick materials, such as cardstock, and can produce vibrant, high-quality prints.

When selecting a printing process for your project, it's important to consider the desired print quality, the complexity of the design, and the quantity of prints needed. Each printing method has its strengths and weaknesses, so it's essential to choose the method that best meets your specific requirements.
