What Is Vector Artwork?
Typically, when our clients submit artwork for printing, we discover that they do not know what a Vector file is. Most individuals that are not professional graphic designers do not have a clue what Vector art is (and why should they) and most companies wouldn't have graphic designers on staff. There are even some individuals working as graphic designers, who do not know what a vector file is. (OK, now that is sad.)
Hopefully we can eradicate a number of the confusion and reply the question... What is Vector Art. We are going to describe, as best we will, what vector artwork is, and how one can recognize it.
Vector art is likely one of the forms of art utilized by computer systems, the opposite type being bitmap artwork (raster). Bitmap art is identified with file names ending in .gif, .bmp, .jpeg, .jpg, .png, and .pcx. Vector artwork files are typically saved as .eps, .ai, or .cdr files. Vector artwork is mathematical algorithms created using software programs, corresponding to Adobe Illustrator, Freehand, Corel Draw, Quark and some others. These programs use mathematic equations and geometric primitives (factors, lines, and shapes) to create artwork that's clean, camera ready, and could be scaled infinitely, without dropping any quality or clarity. The same art may be used for a enterprise card, to a poster, to a billboard.
A bitmap file (raster), is a dot matrix data structure it uses pixels (small dots or squares of coloration) to create an total image. Fairly it is called Raster images or bitmap files they are the same thing.
A bitmap is technically characterized by the width and height of the image in pixels and by the number of bits per pixel (a shade depth, which determines the number of colors it can represent).
The Raster art file has rough, pixilated edges. The artwork turns into distorted when the image is enlarged. Every time you edit the file it loses some of it's clarity.
Raster Graphics, equivalent to pictures, and graphics files created in Adobe Photoshop, Paint Store Pro, and other Raster programs, can be used for some screen printing applications or digital printing. In most cases, particularly with art resembling logos and numerous colors printers need Vector art to achieve the quality print that you want and expect.
1. Can I convert a.BMP,.GIF or.JPG to vector?
Unfortunately no. A bitmap file is created otherwise and just like putting another cover on a book, you continue to have the same pages inside.
2. I converted a Photoshop file to.EPS, why cannot I use this as vector art?
Vector art images use lines to create images, photographs can't normally be was a vector image. A bitmap or raster file makes use of dots, they aren't created in the same manner. In a vector file everything is a separate item. If in case you have an apple with a worm in it you'll be able to change the apple to green at anytime and the worm can change into a tiger when you so choose without altering or affecting the other object. Vector art will need to have been created as a vector file. You can't take a raster file created in Photoshop (for instance) and save it with an.eps,.ai., or.cdr extension and have it magically become a vector file. Once a bitmap always a bitmap unless recreated or traced.
How do you inform if a file is a vector art file?
You'll be able to usually establish vector artwork by process of elimination. If it has the fallacious extension, it is definitely not vector. I encourage customers if they aren't certain enlarge the image to 400 or 800% and if the perimeters are extremely rough and pixilated it is probably NOT a vector image. If you still can't tell send it to your printer and so they can allow you to know. A.pdf file could also be vector or raster. It is dependent upon how it was originally created.
I'll get a little technical right here, hopefully not an excessive amount of! The difference between these types of artwork files lies in how an image is stored within the artwork files themselves. Bitmap files encompass a series of numbers and colors that signify coordinates within the image area's grid. To store a bitmap image, the pc creates a gridwork of the image area. (Pixels are the tiny dots. Keep in mind dot matrix printers.) That's all there is to a bitmap file. A series of numbers representing pixels and their colors.
Vector files usually are nothing like a bitmap file. A vector file accommodates the data for creating lines. It contains a starting point and an ending level for each line. With those coordinates, it also stores a vector equation for each coordinate. A vector equation signifies both direction and velocity. Utilizing these coordinates and vectors, the computer can draw a line from point A to point B with any proper curve automatically created. Vector files sound really technical and sophisticated in their creation.
Vector images have a number of advantages over bitmap images, together with:
If you attempt to enlarge a bitmap image, your computer can only enlarge the dimensions of the squares making up the image area. You still have squares; that's the reason bitmap images get jagged as you enlarge them. Vector images stay smooth because your computer merely re-computes the coordinates of the factors and adjusts the vector equation constants, by no means sacrificing quality.
Each set of lines in a vector image symbolize separate and distinct objects. Each object can be re-edited at any time. For instance, as an example you created a vector art file with a circle within the background. You possibly can open the vector file at any time and change the circle to a sq., oval, apple, etc. Every object is a separate item within a vector file.
Keep in mind that if a professional graphic designer created your art/logo for you, they need to have saved your artwork as vector art file, even when they did not send that file to you. Some designers do not provide their purchasers with vector artwork, because most clients is not going to be able to open the file. When you had a professional logo designed for you, however all you have is a.JPEG, or an analogous file, contact your artist, and ask them for the vector artwork file. Bear in mind, unless you could have specific software to open the file you can't open it; however you'll be able to ship it on to the printer and they should be able to open it.
