Artlogo offers quick and efficient vector artwork services, where you can convert your raster images into a vector format. Our team will work with you to make sure your artwork looks amazing on any item you choose
Raster and Vector are two types of file formats, which have different applications in the world of design. Raster images, often called as bitmap images are made of millions of tiny squares, called pixels. When you zoom a raster image, you will clearly see the square outlines of each pixel. The images captured using a camera or scanner are raster images. Examples of raster files include – jpeg, gif, png etc.
Raster image like a photograph holds a lot of details and are versatile in designs. However, it becomes pixelated and loses resolution when zoomed. These files are acceptable for digital publication and print medium such as books, magazines, and newspapers. Raster images should be saved in a high DPI setting before using them on the print medium.
On the other hand, a vector image is composed of lines and shapes, which are made using mathematical calculations. Such images are created by combining tiles of different shapes and sizes. These shapes are called objects, which display one single color each. If you zoom a vector image, it won’t get pixelated and still look the same. A vector image can be scaled to any size or resolution and is easy to transmit over the Internet.
Vector images are best used for logos and illustrations, technical drawings and other processes that need specialty signs and printing, engraving and etching. The best thing about vector image is that a multi-color vector can easily be converted into a single-color image. Limited colors are often required in the promotional industry to print logos on items such as pens, cups, bottles, etc.
1. Raster to Vector – Using Vectors and Using Vectors& Gradients
An image with color blends can be redrawn in 2 ways:
- Using vectors: When an image is converted into vectors only, the resultant image will be different than the original one. Such vectorized images are suitable for all processes including those that require “True Vector”.
- Using vectors & gradients: An image created using vectors and gradients may look the same or slightly different than the original one, but it won’t be suitable for processes that require 100% vector.
2. Raster to Vector – Using Vectors and Using Vectors& Gradients
We vectorize your black and white images or grayscale images into clear and scalable vector art. A “Line art” graphic is a monochromatic image consisting of lines – either straight or curved. Such image doesn’t have any color blends through a line art can have lines of distinct colors. This type of vector art is acceptable for all processes. A lot of companies prefer vector outlines as it guides the equipment to create the products.
Depending on the process, your vector image will be used for, we will convert your original grayscale image into grayscale vector image or vector line art. Processes that require vector art are engraving, specialty printing, and plotters.
3. Changing an image from CMYK to Solid/Spot color
Most promotional products printers offer CMYK color process printing. If you want to get your artwork imprinted using this method, then you will have to provide a spot color vector file to your printer.
What is CMYK color process?
CMYK refers to the four colors of inks used in commercial printing: cyan, magenta, yellow, and black. All full color printed pieces whether it is a book, menu, flyer or business card are printed using these four basic colors. The printing press runs four times to apply each ink individually.
What is Solid / Spot Color Process?
Spot colors are pre-mixed inks that are applied only to the area assigned for each particular color. For example, to print a black, brown, and red image; black, brown and red pre-mixed inks are used. In this process, the printing press runs only three times cutting down the printing costs.
While printing, raster color images can be separated only into the four CMYK color plates, for that the press will have to run 4 times. If you wish to cut down the printing costs without affecting your design, we can redraw your bitmap images as vector graphics with spot colors. The printed item will look exactly the same as the printing process is done with pre-mixed inks using an exact formula.
