Often, when our prospects submit art for printing, we discover that they don’t know what a Vector file is. Most individuals that aren’t professional graphic designers do not need a clue what Vector art is (and why should they) and most corporations should not have graphic designers on staff. There are even some people working as graphic designers, who do not know what a vector file is. (OK, now that’s sad.)
Hopefully we are able to eradicate among the confusion and answer the question… What’s Vector Art. We will describe, as finest we will, what vector artwork is, and how one can recognize it.
Vector art is one of the types of art utilized by computers, the other kind being bitmap artwork (raster). Bitmap art is identified with file names ending in .gif, .bmp, .jpeg, .jpg, .png, and .pcx. Vector art files are typically saved as .eps, .ai, or .cdr files. Vector art is mathematical algorithms created utilizing software programs, akin to Adobe Illustrator, Freehand, Corel Draw, Quark and a few others. These programs use mathematic equations and geometric primitives (points, lines, and shapes) to create art that is clean, camera ready, and can be scaled infinitely, without dropping any quality or clarity. The same artwork could also be used for a enterprise card, to a poster, to a billboard.
A bitmap file (raster), is a dot matrix data structure it makes use of pixels (small dots or squares of color) to create an total image. Slightly it is called Raster images or bitmap files they’re the identical 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 color depth, which determines the number of colours it can signify).
The Raster artwork file has rough, pixilated edges. The artwork becomes distorted when the picture is enlarged. Each time you edit the file it loses some of it’s clarity.
Raster Graphics, comparable to pictures, and graphics files created in Adobe Photoshop, Paint Store Pro, and different Raster programs, can be utilized for some screen printing applications or digital printing. In most cases, especially with art reminiscent of logos and quite a few colors printers want Vector artwork to achieve the quality print that you really want and expect.
1. Can I convert a.BMP,.GIF or.JPG to vector?
Unfortunately no. A bitmap file is created in another way and just like putting another cover on a book, you continue to have the identical pages inside.
2. I transformed a Photoshop file to.EPS, why can’t I take advantage of this as vector artwork?
Vector art images use lines to create images, photographs can’t normally be changed into a vector image. A bitmap or raster file uses dots, they aren’t created in the identical manner. In a vector file everything is a separate item. You probably have an apple with a worm in it you may change the apple to green at anytime and the worm can develop into a tiger for those who so select without altering or affecting the other object. Vector artwork must have been created as a vector file. You can not take a raster file created in Photoshop (for instance) and save it with an.eps,.ai., or.cdr extension and have it magically turn into a vector file. As soon as a bitmap always a bitmap unless recreated or traced.
How do you tell if a file is a vector art file?
You’ll be able to usually determine vector artwork by process of elimination. If it has the flawed extension, it is definitely not vector. I encourage prospects if they don’t seem to be positive enlarge the image to 400 or 800% and if the edges are extraordinarily rough and pixilated it is probably NOT a vector image. In the event you nonetheless can’t inform send it to your printer and so they can let you know. A.pdf file could also be vector or raster. It relies on how it was initially created.
I’m going to get a little technical here, hopefully not an excessive amount of! The difference between these types of art files lies in how an image is stored within the artwork files themselves. Bitmap files include a series of numbers and colors that represent coordinates within the image area’s grid. To store a bitmap image, the computer creates a gridwork of the image area. (Pixels are the tiny dots. Keep in mind dot matrix printers.) That’s all there may be to a bitmap file. A series of numbers representing pixels and their colors.
Vector files are usually nothing like a bitmap file. A vector file accommodates the information for creating lines. It accommodates a starting point and an ending point for every line. With those coordinates, it additionally stores a vector equation for every coordinate. A vector equation indicates both direction and velocity. Utilizing these coordinates and vectors, the pc can draw a line from point A to level B with any proper curve automatically created. Vector files sound really technical and complex of their creation.
Vector images have a number of advantages over bitmap images, including:
If you attempt to enlarge a bitmap image, your pc can only enlarge the size of the squares making up the image area. You continue to have squares; that is why bitmap images get jagged as you enlarge them. Vector images stay smooth because your pc merely re-computes the coordinates of the points and adjusts the vector equation constants, never 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, to illustrate you created a vector art file with a circle in the background. You might open the vector file at any time and change the circle to a sq., oval, apple, etc. Each object is a separate item within a vector file.
Keep in mind that if a professional graphic designer created your art/brand for you, they need to have saved your artworkwork as vector artwork file, even if they didn’t ship that file to you. Some designers do not provide their shoppers with vector art, because most purchasers won’t be able to open the file. If you happen to had a professional emblem designed for you, however all you will have is a.JPEG, or an identical file, contact your artist, and ask them for the vector art file. Bear in mind, unless you could have specific software to open the file you can’t open it; but you may ship it on to the printer and they should be able to open it.
