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.
A vector image is nice because it is a very small file. Since nothing deals with pixels and only mathematical descriptions they are able to become small by only changing one number. A 2 inch by 4 inch vector based logo would be the same file size as a 2 foot by 4 foot logo. Most vector based logos will be under .10 megabytes, this making them ideally suited for transfer over the internet.
Formats that are commonly used for vector images are EPS (Encapsulated PostScript), WMF (Windows Metafile), CDR (CorelDraw), PLT (Hewlett Packard Language Plot File), SVG (Scalable Vector Graphic), DXF (AutoCAD), and AL (Adobe Illustrator).
Coloring vector objects is similar to coloring with crayons in a coloring book. Its all about staying between the lines. With vector images you can change the color of each individual object without having to worry about pixels. With a drawing program a user can click within an object and define its color, it also enables users to define the color and the widths of lines. Vector images are much easier to color then bitmaps.
Unlike using dpi such as a raster image does, a vector image is defined by math. When a program sizes a vector image up and down, it is simply multiplying the mathematical description of the object by a scaling factor. An example would be, in order to double the size of a 1” square object, it would need to be multiplied by a factor of 2. The math is simply recalculated to produce an object double the size. Since vector images are capable of scaling up or down without the loss of image quality, they can be printed at any resolution that a printer is able to produce. Because the vector images don’t use dots per inch or scanning resolution like the raster images, they create a much better quality and this is a big reason why vector graphics are mainly used in clip art.
Instead of using dots or pixels like a raster image, a vector image consist of connected line and curves to produce an object. In the process of creating a vector image, you must start with a vector illustration program, node or drawing points are inserted and connected together by lines or curves. All aspects of a vector image are defined by math including node position, node location, line length and down the line. Text objects are produced by connecting nodes, lines and curves. Unlike the pixel oriented raster images, vector images are object oriented. Every letter in a font starts as a vector image. A vector image will have a “wireframe” underneath the colors in the object. Vector images are like putting the body over the frame of a car.
