PROGRAMS
The program one chooses when building a logo is actually far more important that many people realize; even seasoned professionals. In order to achieve maximum versatility (in terms of size, ease of editing, and format conversion) its very important to design using a vector-based illustration program. The three biggest vector illustration programs are Adobe Illustrator (the most widely used), Corel Draw (my personal favorite), and Macromedia Freehand. One can expect to pay between $500-$700 for each program, individually. Some are available as part of larger software collections and can be found bundled with other programs for around $1000 (Adobes Design Collection being a notable example; get Illustrator, Photoshop, InDesign and Acrobat), or as competitive upgrades (if you already own a qualifying product) for as little as $150.
Choosing the right program is of paramount importance when beginning any project. A vector program when doing logo design is akin to using an image editor to touch up a photo, or a layout program to design an ad. Sure, one can use an image editing program like Photoshop to design a logo or create an ad layout, but it really isnt what the software is designed to do, and as a result, you will encounter limitations of some varying degrees.
So why would one use a vector illustration program instead of an image editor or layout program when designing a logo? One word: versatility.
An illustration program uses a series of mathematical points and lines to create images. This gives the logo the ability to be scaled to any size without any loss of image quality. Additionally, an Illustration program offers the ease of simplicity when converting to any other graphics file format. For example, a native Illustrator file can be exported/saved to TIFF, JPEG, PSD, EPS, GIF, SVG, BMP or PDF file formats. Its easy to go from vector to raster, but in many cases its nearly impossible to go from raster to vector. There are some programs like Adobe Streamline or Corel Trace that do a decent job in converting simple raster images to vector file, but struggle in maintaining realism with more photorealistic images. Vector files usually also result in smaller file sizes when compared to their raster counterparts, which serves as an added benefit when storing or emailing files. Since vector images also use mathematical points do define the image, output to printing devices will yield sharper images at all sizes than identical raster images.
An image editor uses pixels to define an image. The plus side to this is that a greater range of photorealism is achievable and a variety of specialty effects can be applied. The problem is three-fold. The first problem is that photorealism and special effects actually work against good logo design (as will be discussed a little later). Secondly, since an image-editing program does depend on pixels, not mathematical points, it cannot be scaled without loss of quality. One can shrink the logo to a fair degree and still maintain image quality, but the logo cannot be scaled upwards without losing integrity. Doing so can result in image blurriness or pixilation (both of which are not desirable). Since one would need to create a logo that would be the most versatile, that logo would need to be initially created with such size and resolution that the mere file size would likely prohibit effective utilization on most computers and applications. Lastly, raster images arent easily converted to vector-based formats. This limits the logo to formats like TIFF, JPEG, PSD, BMP, GIF and PDF formats. These formats will work for most print applications (newspapers, magazines, posters, etc), but not so well for things like vinyl signs, embossing/engraving or promotional products, where the vendors work almost exclusively with vector images.
Though it doesnt happen as much, some choose to use a layout program as the primary means of logo creation. This just adds difficulty to an already challenging undertaking. Where TIFF, EPS, PDF, JPEG and BMP files will pretty much work in any layout application, files designed in Quark, PageMaker, InDesign or (gasp) any of the Microsoft products (Word, Excel, Powerpoint, Publisher) are pretty much only good in the program that created it and not generally as versatile. One has to jump though hoops in order to get a layout program-based logo into formats that can be utilized by other programs. Of all the layout programs, InDesign is probably the layout program best suited toward logo creation because it has some of the basic illustration tools available in Illustrator and has the most file format export options; it can also read native Quark and PageMaker files. Quark and PageMaker do offer an export to EPS option, but experience has shown me that to be a somewhat unpredictable experience. One really has to know a great deal about all the individual program capabilities in order to get a layout program to export its creation to a format that can be utilized by other programs. Sometimes the only way is via a screen capture, scanning a printout or printing to a PDF file, which adds just another unnecessary step to an already time consuming process.
The bottom line is that for any project, one should choose the right tool for the right job. For logo design, that tool is a vector illustration program.
