Pro Tips for Sizing and Production
Making greeting cards is fun. But you need to know a few things.
The 1/4" Rule
The 1/4 inch Rule- You are then to allow a small portion of space around the edge of the greeting card design about a quarter inch. This area is known as a safe zone. It helps to make sure that large contents or pictures are not removed through printing and cutting the card. Placing words or images too close to the edge could make them look wrong when they have been cut. That is why it is nice to place everything in the 1/4" gap so as to present your card as professional.
Understanding "Bleed"
Bleed is a printing word meaning that your design goes outside the card border. It is used when you are not desiring the colors or pictures to have a white frame that stretches to the edge. To do this, you must make your design a bit larger than the size of your end product or the card. As an example, your card can be 5x 7 but you can make it 5.25x 7.25 with a bleed. This extra room is eliminated after printing. The use of the greeting card dimensions with bleed is also necessary to clean the card and make it neat and tidy.
Paper Weight & Thickness
Card feel is dependent on paper weight and thickness. Sturdy paper is mighty and fine. The paper is thin such that it is bendable or tearable. The paper weight is calculated in pounds (lb) or grams per square meter (gsm). The paper used should be heavy, like 80 lbs or 300 gsm, in the case of greeting cards. It is highly powerful and pleasant-looking. Your card feels good on the right paper. We allow you to select the correct paper depending on your card style and budget.
