You’ve probably heard the term “vector image” or “vector graphic” used when doing research on creating your own custom printed boxes, and wondered: “what is a vector image?”
Vector images are lines and curves (known as paths) which can be scaled without losing their quality. There are many forms of vector files, but some of the most commonly known and used for design are .eps and .ai.
.eps (Encapsulated Postscript): it is the standard format within printing. When creating anything, files should always be in .eps.
.ai (Adobe Illustrator): is an Adobe format which is another version of .eps. It’s commonly used, and like .eps, files should be saved in .ai and it is advised to also have an .eps format as well.
One more thing: raster images. Raster images are the standard within digital photography, and most commonly used when graphics are already published digitally. Unlike vector images, which are made up of points, lines and curves, raster images are made up of dots on a grid, also known as pixels, that are each assigned a specific colour.
Like a vector image, you can scale down its size, however, once you try increasing its size the quality will become very blurry. The reason for this is that you are shrinking or stretching the pixels.
Vector images always appear smooth, no matter how small or large you make them, which is critical to getting a high quality print on your box. You can create a logo for your website, but if it’s saved as a vector image, you can easily make changes and use it for various purposes, including packaging.
Using vector images are vital to creating graphics for your custom printed boxes. Not only do they ensure good quality print, but understanding and using them also helps with creating a consistent brand identity.
