Vectors V Rasterisation

Recently I was prompted by a question in a chat room where someone was asking advice about designing logos using Photoshop. Photoshop is a versatile enough package for photo-editing, but the end results are primarily ‘bitmapped’, i.e. made up of a predetermined number of pixels. To create the illusion of curves, the software uses a clever mixture of colours to fool the eye.  None of this matters with small, reduced pixel images, making the programme great for the creation of web banners and such like.  But when the image needs to be enlarged, or requires higher definition, the image is likely to become fuzzy and sometimes unexpected stray colours creep in (known in the trade as noise).

The alternative is Vector Drawing, where an area of colour or gradient is described by the coordinates of a bounding shape. The most common form of vector usage is the fonts on your computer. The advantage with a vector drawing is that it can be enlarged infinitely without losing any detail. All company logos should ideally be designed as vector drawings. No doubt raster copies will be required, particularly for web and Microsoft applications, but even the most web-based company may one day wish for a large version of their logo, possibly for an exhibition stand, a van graphic, or other large scale promotional print material.

Just one more reason why it’s good business sense to consult a Graphic Designer early in your business’s life to ensure your branding and business image start out on a firm, professional footing.  Contact us NOW for advice: 01223 902231.
