There are two main kind of picture files: Raster and also Vector. Raster images are produced with pixel-based software application or captured with a camera or scanner. They are more common in general such as jpg, gif, png, and are widely offered on the web. Vector graphics space math-defined shapes created with vector software and also are no as common; provided in CAD/engineering, 3D animation, and also Graphic design for procedures that reproduce picture onto an item such together engraving, etching, cut stencils.

You are watching: Which of the following options are well suited for using vector graphics?

When making use of a raster regimen you paint picture and it"s similar to dipping a brush in paint and painting. You have the right to blend colors come soften the change from one shade to another. FIG.1

When using a vector routine you draw the outline of shapes: and it"s similar to creating picture with tiles that all different shapes and sizes. E.g. One eye shape, a nose shape, a lip shape. This shapes called objects screen one solitary color each. FIG.2


A many images deserve to be made v either raster or vector program and also look precisely the very same on both programs. Photos with a subtle gradation that one color to one more are the pictures that will look most different because vector programs require to create a different shape for each the shade of color. FIG.3


Some vector program do have actually the capability to create color gradients in ~ one solitary shape, yet these space actually raster effects. A vector graphic through gradients includes both vector and raster elements and won"t be suitable for procedure that calls for 100% true vector arts such together cutting or engraving.

Photographs space raster images and are most likely the ideal example that images totally made of color blends - or shade blends in the situation of black and also white photographs - and also those photos look really different when attracted in vector format. Click right here for examples.

Pixels vs Vectors

Raster pictures are made of pixels. A pixel is a single point or the smallest solitary element in a display screen device. If you zoom in to a raster image you may start to view a lot of tiny tiny squares.

Vector pictures are math calculations native one allude to one more that form lines and shapes. If friend zoom into a vector graphic that will always look the same.


A raster image has actually a specific variety of pixels. When you enlarge the image document without transforming the number of pixels, the photo will watch blurry. Once you enlarge the paper by adding much more pixels, the pixels are added randomly transparent the image, seldom producing an excellent results.

When friend enlarge a vector graphic, the mathematics formulas remain the same, rendering the same visual graphic no matter the size. Vector graphics can be scaled to any type of size without shedding quality.

Vector Graphics

Vector graphics space scalable

Because vector graphics are not created of pixels they space resolution-independent. Vectors have the right to be scaled to any type of size without shedding quality. Vectors deserve to be printed as huge and in ~ the highest resolution the press or the output machine allows.

Color modifying is simple

A multi-color vector image can be easily changed to a limited color graphic. Minimal colors are often forced by some processes such as embroidery, "stencil-cut" vinyl signs, and specialty promotional items (such as logos printed on cups, pens, bottles, etc.)

Vector synopsis / Wireframe

Vector programs display screen the image as us would normally see it and also they also permits us to check out the vector overview or wire-frame of every object. This vector outline/wireframe is necessary to part companies since it guides the tools they usage to create their products, such together engraving and cut signs. The is also important to few of these procedures that the vector outlines space not overly complex.


For categorizing purposes I have named the above: photo-realistic vector, vector illustration, and vector lineart.

1. Photo-realistic vector: picture vectorized utilizing an automatically tool and also a multitude of colour to permit the photo to have a closer same to the original. We hardly ever auto-trace photos and do no recommend it. This is an example of something that does not usually work as the is too complicated for processes that space guided by the vector rundown such as engraving & specialty signs. This vector photo may be supplied in CMYK or digital printing however photographs are best printed as they are: raster images. Discover more.

2. Vector illustration + raster effects. This is a hand-drawn, simplified drawing. Color blends have the right to be developed in vector programs however they space actually raster effects therefore this photo is no 100% vector. The raster impacts will show up as rectangle or square "boxes" as soon as the graphic is imported into specialty software. This photo is likewise not suitable for processes that space guided by the vector outline. Samples.

3. Vector "line art". This is 100% vector; NO shade BLENDS. The outline/wire-frame is acceptable for all processes. Samples

Vector Graphic common Uses

Vector graphic are typically used because that logos, illustrations, technological drawings, 3D graphic & animations.

We provide vector drawings for these services:

Specialty printing: e.g. Coffee mugs, frisbees, koozies Signs and banners: cut, sandblasted, sculpted Engraving Etching steel stamping Laser sculpture or laser cutting Decals, labels, stickers large format to press Raster / Bitmap images

Pixel-based photos represent and also edit photographs and photo-like images better than vector programs, because they can use one abundant variety of different color pixels. By arranging pixels and slowly incrementing or transforming the shade or the shade of the pixels nearby to them, it creates a subtle gradation indigenous one shade to another: nice and smooth shade blends.

Raster images" dimensions are measured in pixels. Because raster pictures cannot be enlarged without losing quality, printers require that you administer them with records at the correct size: 1. The measurement you want to publish your image at, and also 2. The pixel resolution because that that details project. The pixel resolution is the lot of pixels within each inch referred to as ppi (pixels per inch).

How big a raster image have the right to be printed - and maintain top quality - depends on 2 things:

the pixel measurement of the photo (e.g. 6824 pixels broad by 2345 pixels high) the pixel resolution: pixels-per-inch (ppi), how many pixels per inch are required by the particular printer

Different species of printing have different resolution requirements. ~ above average:

Paper printing require a minimum that 300 ppi shirts printers call for a minimum of 240 ppi huge format printers (banners, billboards) differ a lot due to the fact that it additionally depends on the street from which the sign is going to be viewed - could be as low as 20 or much more than 200

How to identify what dimension your raster image must be for printing:

Multiply the resolution forced by the area to be printed. Example:

If a printer calls for a minimum of 300 ppi and also you desire to print picture in an area the is 5 customs wide, main point 300 pixels x 5 inch = 1500. Your image must be at least 1500 pixels wide.

Can we enlarge the pixel measurement & resolution that a raster image?

Raster images have a certain amount of pixels within every inch. A 72 ppi image has actually 72 pixels in every inch. A 300 ppi image has actually 300 pixels every inch. When you are forced to provide a "large or high resolution" image record (a particular size), the image must have been developed or scanned in ~ that size or bigger (at both the dimension and also the resolution required.) E.G. If you must print an image at 2 inches large and 300 ppi is required, your image must be created, photographed or scanned at a minimum that 600 pixels (2 in x 300 ppi).

Once the picture is developed at a certain dimension, you might not be able to use this photo at a larger size without shedding quality. Once you manually increase the resolution v a program prefer Photoshop, Photoshop randomly to add pixels and the result will most likely be a high resolution picture of poor quality.

Sample of a raster photo below:


How to determine what measurement your image have the right to be printed at good quality:

Divide the pixel measurement of your photo by the resolution forced by your printer. Example:

If image is 1024 pixels broad & printer needs 300 ppi (1024 ÷ 300) = image have the right to be published at 3.413" wide.

If ns am creating a new design i m sorry software should I use; Raster or Vector?

It relies on the design itself. If it"s walk to have actually photographic facets with constant tones and blends that color, you room probably much better off utilizing a repaint program. If you desire your architecture to look prefer a illustration or illustration v clear contrast between the elements of the design, then use a vector program.

Ideally a agency that has a logo style with photographic elements, additionally has a secondary simplified version of their logo in vector layout that have the right to be supplied for those specialty item that need vector art such together plotters, engravers, vinyl-cut signs, promotion specialty item (cups, pens, bottles with firm logo) Sample below:
