What is a vector EPS image?

A vector EPS image is made up of lines and curves joined together via anchor points set by mathematical calculations. It is not made up of dots nor can it be high or low resolution. Vector EPS images are easy to edit, perfectly scaled without compromising the quality and able to apply PMS colours. Vector EPS images are ideal for logos, illustrations, mock ups and line drawings. Vector EPS file sizes are typically smaller when compared to bitmap images.

Why do most decorators insist on only receiving vector EPS images?

Vector EPS images are very easy to edit, scale, crop, manipulate and apply PMS colours. They have 100% control and freedom for preparing artwork for decorating. (eg: separating, trapping, bleeding, adding white under-bases).

What is a bitmap image?

A bitmap image is made up of tiny coloured pixels/dots set in rows and columns to create a photo realistic image or drawing. The quality, overall size and sharpness of a bitmap image relies on the resolution (dots per inch – dpi) because bitmap images are resolution dependant. Bitmap images can be either high or low resolution.

High resolution images have more coloured dots (300dpi) and this allows for greater detail and colour subtleness. Most commonly used for printing photo realistic results. File sizes are typically larger.

Low resolution images have less dots (72dpi) and less colour detail. Most commonly used for online purposes. Compared to high res, low resolution images are much smaller in file size.

What is a logo redraw?

Perfectly tracing over a bitmap logo (say a .jpg) within a vector based program (like Adobe Illustrator). Once the redrawing has been completed, the bitmap image is removed and the redrawn logo is saved as a perfect true vector EPS image. All the properties of a vector EPS now apply to this redrawn logo. The best and most accurate way to redraw a logo is by hand using the pen tool. 

What is the difference between CMYK, RGB and PMS colours?

CMYK – Cyan, Magenta, Yellow, Key (aka – black). These are process colour inks, perfect for photo realistic printing (eg: magazines, catalogues, etc…).

RGB – Red, Green, Blue. TV’s and computer monitors emit RGB light to create coloured images.

PMS – Pantone Matching System® . A world standard numbered ink system.
