Pixelation is not good!
Everyday, SS Graphics receives screen printing requests accompanied by artwork that is not acceptable for printing.
What is pixelation? In its most simplest terms it is an effect caused when a bitmapped image is enlarged to a size such that individual pixels become visible. Pixels are the small square building blocks of bitmapped images.
Aspiring graphic designers please take note; most clip art is very low resolution bit mapped files (tiffs, jpegs, etc.), and should not be used for professional design purposes. Images that are used for web graphics are typically 72 dpi (dots per inch) very low resolution and are not acceptable for any type of professional printing.
Below is an example of an image which is acceptable for website usage:
Look what happens when we scale the image for large format printing. (Please note that this image size was only increased by a factor of 3.)
This is pixelation.
Typically the next response we get from our client is, how much will it cost to have it made into a usable format? In this example that may not even be possible or may be cost prohibitive. The top image is too small to accurately trace and the bottom image is too pixelated to accurately trace. In order to recreate this logo for large format printing it would have to be completely redrawn from scratch.
At SignOutfitters.com we require all bitmapped images to be provided as a digital file with 300 dpi of resolution at finished size.
