Depending on your industry and the purpose of your business card, I usually encourage clients to add a specialty finish, either Metallic, Spot UV, Plastic, Ultra thick, Soft touch, or Pearl. I'm an advocate of tailoring business cards to each and every client.
Anyone who has been to a networking event knows how important a great business card design can be to stand out from the crowd. It is an extension of your brand and is crucial in promoting your message long after you've left a meeting.
My process is simple: I ask for a clear and detailed business card design brief, and for my client to provide any required assets (such as a logo, company colors, etc.) and defining their budget. During the creative journey, my client provides constructive, direct feedback to ensure they get a perfect business card design.
