Offset printing is a traditional printing method that uses printing plates to transfer ink onto paper or cardstock. It is suitable for printing on a wide range of paper stocks, including cardstock. Offset printing is a good option for high-volume printing jobs, as it offers high-quality and consistent results.

Digital printing is a newer printing technology that uses digital files to print images onto paper or cardstock. Digital printing is a good option for short-run printing jobs, as it offers quick turnaround times and variable data printing capabilities. Digital printing also offers high-quality and consistent results, making it suitable for printing on 450gsm matte cardstock.

Letterpress printing is another traditional printing method that uses a printing press to transfer ink onto paper or cardstock. It is a labor-intensive process that involves setting type and applying pressure to create an impression on the paper or cardstock. Letterpress printing is a good option for small print runs and offers a unique and tactile quality to printed materials.

In summary, offset printing, digital printing, and letterpress printing are all commercially available printing processes that can print on 450gsm matte cardstock. The choice of printing process will depend on the specific requirements of the printing job, including the desired print quality, quantity, and turnaround time.
