Post Planting Depth

WHAT DEPTH HOLE SHOULD I DIG?

Digging the correct depth hole.

Many installers, both good and bad, have a preconceived idea on how deep a hole should be to accommodate a sign post.

There is no substitute for experience, but the table below is a good starting point for those of us with little, or no experience at all.

Please note that this is a guide only, if in doubt please contact your local civil engineering department for more information.

Vector vs Raster

What are Vector Images?
Vector images use mathematical equations to define each component of an image. This allows vector images to retain their high-quality at any size. When possible, use vector graphics created in a desktop publishing program.

What are Raster Images?
A raster image is composed of a collection of tiny dots called pixels. When these pixels are small, and placed close together, they fool the eye into forming a single image. Raster images work well when subtle gradations of color are necessary. Because they contain a fixed number of pixels, a major disadvantage of raster images is that their quality suffers when they are enlarged or otherwise tansformed. They are also large in file size.

CMYK vs RGB

CMYK (Cyan, Magenta, Yellow and Black) are the colors used in the printing process, whereas RGB (Red, Green and Blue) are the colours used by screen displays such as your monitor. Please note that JPEG files are almost always in RGB.

Your document should be created in CMYK mode so that the colors that you see on the screen most closely match the final printed product. If you create your document in RGB, the colors in your printed product may vary slightly. Many of the bright values produced by your monitor cannot be reproduced in print.

Resolution

What is resolution?
Resolution refers to the number of dots per inch (dpi), or the amount of detail the image has. Most documents prepared for upload should be 300 dpi at 100% of the final print size. Higher resolution means a more detailed image, and also larger file and longer upload time.
