By definition, postcards are any cards used to send mail messages by post without the use of an envelope. It can be a simple plain card which is a rectangular piece of stiff paper with printed greetings and pictures, commonly used for personal correspondence; the lettercard, a type of postcard that folds in half so that the message is inside; and the picture postcard, which is a postcard with picture on one side, commonly used for business ends.

Perhaps it would be safe to assume that even for once you have seen a type of postcard. But for those of you who are not quite well-versed with the printing lingo, if you try to order postcard prints from commercial printers, you will of course get stumped with the terms 4/0, or 4/1, or 4/4. For clarity, 4/0 means full color prints are applied on the front and blank on the back, while the 4/1 refers to a full colored front graphics with only a single black color on the back; and the 4/4 of course implies full color on both sides.

The 4/0 type of post card is commonly used for personal correspondence. This is because you are able to get full color printed display of the design on the front, while free to write any message you might have at the back. This kind of print can be obtained through the 4/0 full color post cards printing service provided by printing companies. The results are a very good tool for capturing and holding the attention of your recipient for a long time – both in the purpose of looking at the images and at the same time, reading the short message at the back. That is the real purpose of why most full color postcard printing services opt to go for the 4/0 full color post cards printing since it gives them more freedom in doing whatever they want with their prints. While for customers, it gives ease in reading and viewing of both designs and texts.

Moreover, when it comes to customizing your prints, the 4/0 full color post cards printing is the perfect choice. It does not matter what images you have as long as it can be processed in complete four colors only, and leaving blank at the back.
