The examples illustrate what benefits vector graphics hold for your designs. The most popular software is Adobe Illustrator (commercial) and Inkscape (open source). But their processing is much more demanding and requires special graphics programs. Since vector graphics only contain geometric shapes, they are very small when compared to pixel graphics. The image information is rendered for each size you replicate. This is how vector graphics can be scaled without any loss of quality while remaining razor sharp. Vector graphics don’t replicate the design with pixels, but with geometric shapes that are rendered as mathematical formulae. While pixel graphics are everywhere, vector graphics occupy a rather small but high-quality niche. In this FAQ we’ll show you how to do it.Ī line says more than a thousand pixels: Vector Graphics When creating high-resolution images from smaller images, a lack of quality will show when enlarged. An enlargement of the design is only possible with a loss of quality. The lower the resolution of a design (the fewer pixels per inch), the more easily the individual pixels cen be detected. 200 dpi means that there are 200 pixels per inch (= 2.54 cm). The resolution of a design is usually provided in dpi (dots per inch). An example: In a red circle with 1,000 pixels, the position and its colour values of each individual pixel are saved. Photos or designs with a high degree of detail, as well as drawings, illustrations and designs with colour gradients.ĭigital printing, laser transfer, thermal sublimationĮach graphics file consists of individual pixels.Įach pixel has its individual colour information. Popular software to create pixel graphics include Adobe Photoshop (commercial) or Gimp (open source). The biggest advantage of pixel graphics is that they can be edited quickly, easily and without much previous knowledge with any smartphone, tablet or computer. This is why the file size of high-resolution photos is quite large, because they’re made up of millions of individual pixels. If the resolution is too low, the pixels will be clearly visible. But if the individual pixels are too large (meaning the resolution is too low), the photo appears pixelated. The smaller and more detailed the individual pixels, the sharper the photo. The image information of the photo is saved by means of individual colour points (pixels). Almost every digital photo is a pixel graphics file. Today, pixel graphics visualise most of what you see on smartphones, digi cams or computers. Vector images are used as a 'map' by dedicated tools: plotters, machine. For example, if a logo image is low quality and pixels are visible when enlarged, it can be converted into a vector object that can be scaled up to the desired size without losing sharpness. Keep reading to find out when to use which file, and how to realise your ideas in the best way possible. What are vector images used for Vector graphics are mainly used in visual design. You can express your design ideas in two fundamentally different ways at Spreadshirt: Either as a pixel or a vector graphic.
