Many Web designers recruited in various web design companies come to the Web with a print background. Either they were print designers, or they are just used to the control that a print world gives. When you print something, it provides permanence and stability. You don’t have this on the Web.
As a website design company designer, you’ll need to work with customers. You will be doing them and yourself a disservice if you don’t explain the difference between print and the Web. Especially if you bring your portfolio as print outs. This is a common problem, where the customer expects the printout to represent exactly what the page will look like.
- Printouts as a Portfolio
It is always important to have a portfolio, but remember that the Web is not print, and bringing a print out is not a strong representation of your Web site design skills.
- Setting Expectations
Be up-front with your customers. If they want their page to have very specific layout, font, and design elements, be sure to explain the tradeoffs such as download speed and maintenance before simply building them a completely graphical page.
- Know what your customer uses
If you’re a big Netscape on the Mac fan, and your client only uses Internet Explorer for Windows, you should keep this in mind in your web designs. Your page could look very different to them.
