Evolving file formats
In a post last year I explained ‘Why the designer needs an EPS‘. A post to clarify the differences between Vector and Bitmap files and why one might be preferable to the other. Near the end of the post I mentioned that we provide all our logo art work as PDF and PNG files. Today I’m going to explain why we made that decision, and why it’s better for our client and their suppliers.
EPS Good, PDF Better.
What could make EPS files better? Well wouldn’t it be nice if you could see the artwork.
The PDF file format is not really one type of file, but rather a wrapper for different files that gives them more flexibility and most importantly visability. PDFs can contain vector or bitmap information or a combination of both. They can be low resolution for web or email or high resolution for press or publication. They can even incorporate forms, mark-up, comments and links. But there most important feature is that they can be read and seen by, easily, by most users.
For our logo artwork we use Illustrator vector files, saved as Illustrator Default PDFs. This means the files keep all the Illustrator format abilities (layers, transparencies etc) are resolution independent vectors (can scale to any size) and are enclosed in the PDF file format (so you can see the artwork). They are basically an EPS file wrapped in a PDF format. They can be placed in and used by any professional design application. They can be opened and edited by any professional vector editing program.
JPG Easy, PNG Easiest.
How about using an image format that didn’t start off by degrading the image.
As with the vector version of the file we have settled on what we consider to be a superior format for electronic publishing. While JPGs are a standard everybody knows they have a dirty secret. They throw away information! That’s right, JPG is a lossy compression technology. The reason it makes files so small is because it doesn’t keep all the information. Part of this process also involves the softening or blurring of sharp edges, the kind of edges that are commonly found in logos. While this was necessary when were all on dial up modems, it’s no longer true today. PNG files provide superior quality while maintaining crisp graphic edges with the benefit of transparency. PNG files are compatible with all browsers, modern email clients and, importantly for our clients, Word, Powerpoint & Excel.
Start with the best.
If you want to make sure you logo always looks good start out with the highest quality files.
As we like to supply our clients with the best quality master files for there new identity we supply them with PDF and PNG files. From there the files can be converted or transformed into the best format for the particular application. We reason: if you have the highest quality artwork in the most flexible format you are giving your new identity the best possible start.
If you’d like to make sure your next identity gets off to the best possible start, give us a call.
