Ugly Sign Reward

Here at Laser Sharp Sign Design we have come up with a contest to reward anybody supporting Laser Sharp Sign Design. There is no limit on winners or how many times you can win. We are simply asking you to help us by spotting ugly signs in your area. We are based out of Tampa, Fl and will be able to replace signs nearby with more ease than one that may be out of state. Either way we want to see your photos!! Along with the picture of the sign you only need to supply us with the sign owners contact info. If the owner goes through with the transaction you will be rewarded with a percentage of what the sign was worth.

All photos should be posted on our Facebook timeline. If you havent liked us just simply click the link below (or copy and paste into URL bar). Once we have your images we will get in touch and keep you updated with the owners decisions. This is a simple way to put cash in your pocket and we sure could use your help!

You can check out our Facebook page to see a few examples of bad signs. In the end its a judgement call if you are having trouble  interpreting a sign theres a good chance other people are having the same problem, all you have to do is take the picture and we will fix it. Some examples of what to look for: wear and tear, fading, discolored, misspelling, knocked down from support, bent or just flat out ugly.

Wrap Care

If you have transformed your bland old paint job into a unique or business advertising vehicle wrap, I would like to congratulate you. You have now successfully put your car into a new realm that will have all the people on the streets looking your way. Having a vinyl wrap is different then a paint job and requires a little different care.

1) Automatic car washes are now out of the question. The high pressure water and bristles from the machine will cause damage to your wrap and costly repairs. You should hand wash your car with a sponge, and a low pressure or mist of water. If you have to use a high pressure water system be sure to stand back at a distance and not to hold the stream on one point of the car, doing so could cause a tear in your vinyl.

2) When using wax, be sure to hand wax your car and DO NOT use a buffer. There are different kinds of wax, be sure to use one that is suitable for vinyl such as turtle wax. If you go to get your vehicle detailed be sure that they also use a wax that is vinyl friendly. Waxing your vehicle will keep your wrap clean and polished and also make it easier to deinstall of the wrap, leaving little to no adhesive behind.

3) Avoid parking under trees for any long periods of time. Sap from some trees can damage your wrap causing you more money.

4) If you have window perf it should be waxed as well. It will give your perf a longer life span and help the lamination. Do not use high pressure on the window perf as well, it can also cause damage.

Be sure to protect your wrap, it is an investment and bad care can cause to money down the drain.

Raster Resolution

DPI, known as Dots Per Inch, is the resolution of a raster image or scanned image. Printer and scanner resolutions are also measured in dpi. Your typical desktop laser printer will print at 300-600 dpi. At laser Sharp Sign Design we use a HP Laser Printer, with a very high dpi it gives us the ability to create smoother and cleaner products. The poducts final quality of printing depends on the resolution of the image being used to print, called the bitmap or scan.

Take a 400 dpi image and increase the size in a graphics program. When you do this, you have only made the tiny pixel squares bigger. This creates whats called the “jaggies”, by making the image bigger it gave you a jaggy edge. When dealing with raster images know that in order to “blow it up” you must have a high resolution picture or be able to transvert the image into a vector file using programs such as Coreltrace or Eurovector.

Raster File Size and Formats

The only way for you to accuratly reproduce a raster image file is to have graphics software to keep track of the exact location and color of each pixel in the whole collection of pixels, thats a lot of information. File size becomes a big issue when scanning and creating raster images. When the file sizes star to get bigger it becomes an issue because big files make your computer processor and hard drive work overtime. Your typical 2″ by 3″ 150 dpi black and white raster logo is about .07 megabytes or less then 70k in file size. That same file saved as a 300 dpi 24 bit raster image logo might be 100 times larger, over 7 megabytes. In order to transfer big files (over 1 megabyte) you must have high speed internet connection on both ends for timely uploads and downloads.

Common raster image formats are JPEG (Joint Photographics Expert Group), PCX (Paintbrush), TIFF (Tag Interleave Format), BMP (Windows Bitmap), PNG (Portable Network Graphics), CPT (Corel PhotoPaint), and PSD (Adobe PhotoShop).

Raster Images

A raster image forms pixels, a collection of a tiny colored square.

When an image gets scanned, it becomes converted into a collection of pixels called a raster image. The most common form of a raster image are scanned graphics and web graphics (JPEG and GIF files).
