![]() ![]() See the below vector-image which shows an enlarged area of the curves and lines that make up the overall image. Vector graphics can be saved in the below formats: The great thing about these formulas is that they make vectors infinitely scalable, keeping the quality the same as the original at any size. ![]() ![]() These formulas capture shape and colour to build an overall image. In its simplest terms, think of the puzzle game dot-to-dot where lines and curves are drawn to connect the dots and reveal the outline of an object. Vector or Scalable Vector Graphics (SVG) consist of dots, connected by paths and curves which are controlled by mathematical formulas within the software. We do not recommend using images above 100% of their original size to ensure you achieve a good result on your personalised printed packaging. The general rule of thumb when re-sizing is to downscale only. If you enlarge the image, the pixels stretch to fill the expanding surface area and the existing pixels become more apparent. Since raster images are comprised of a fixed number of pixels, the image cannot be scaled up in size without sacrificing its quality. A low-quality image is typically set to 72PPI whereas a high-quality image is typically set to 300PPI. The quantity of pixels included in an image is defined by pixels per inch (PPI). This starts to distort and blur the image. The less pixels included per inch, the larger the pixels become and the more noticeable they appear. The more pixels per inch, the smoother the shape and blend of colour which in turn, produces a higher quality image. When a raster-image is created, it contains a fixed number of pixels. Images posted on the web are typically set to this resolution. An example of a raster-image exported at 72ppi (pixels per inch). You can see the individual colour squares which are a key indicator of a rasterized image. See the below raster-image which shows an enlarged area of the pixels. In large quantity, these pixels form an overall image, like a mosaic. Raster graphics are comprised of lots of tiny, colour squares called pixels. *A PDF can contain both raster and vector images. If you have a file saved in the above format, it will always be a raster-image. Raster (or bitmap) graphics are images that are in the form of digitised photographs or detailed graphics and illustrations. When considering these print options, it is important to understand what type of imagery you should be using to produce clean, high quality print designs. In this article, we aim to bust the jargon surrounding image types. We do our best to make navigating the development of your first bespoke packaging as easy as possible, but if you haven't dealt with any printed materials before, inevitably there is going to be some terminology that you are not familiar with: including the terms raster and vector. When purchasing printed cardboard packaging, you have a variety of print optionsreadily available to you. ![]()
