The Trim Zone
Your design should be approximately
0.25" inches larger than the actual card size to account for tiny variations in how the card gets cut after printing.
For example: a
4" x 6" postcard design should be
4.25" x 6.25". This extra space is called the bleed area. Backgrounds should extend into the bleed area to ensure there is no white border when the card gets trimmed, but no important images or text should be in the bleed area.
The Text Safe Zone
Keeping all text within the safe zone is important to make sure no important content is cut off during the trimming process.
The Ink-Free Area
On the back of the postcards, there is a space marked off as the
INK-FREE AREA Anything in this area will not be printed to leave room for the postage and address information.
When using PNGs or JPEGs, a minimum of 300 dpi is required. DPI is calculated as (width of image in pixels) / (width of product in inches) and (length of image in pixels) / (length of product in inches). For Example:
1275px x 1875px image used to create a
4.25" x 6.25" postcard has a DPI of 300.
