Once again I have some popup banners to design. You know, these roll up banners that pack neatly away into a carry bag... Well your basic banner design principles once again count here.

Client brief was that they'd be using it at events and seminars. Now I don't know about you, but when I'm attending an event, I'm seldomly going to stop in my tracks to read a whole company mission or vision statement (that's what the client suggested). I suggested to apply the infamous KISS (keep it simple stupid!) principle and ditched the statements for something more catchy. A one phraser that tell prospective clients exactly what the client does and also carrying over their most important values. In the end, a much more effective banner, with larger text and visuals to do what banners do best, attract interest.

I can't begin to say how important a slick design is. You need good effective stock photography if you're going that route, or strong vector based simple design layout. After all, with stock, you're selling a lifestyle and your trying to create a mood. Often, once single striking image as backdrop for your banner could accomplish just that. Just make sure your text sits well on such a background or make sure you have sufficient non-effect to make it stand out. What's non-effect? Well, putting effects like stroke or drop shadow on objects without making it apparent that they're really there, so downtoning it a bit.

Also remember any print material done for a client must create brand awareness, so make sure you convey the message. Louder if you're working with a lesser known brand and toned down, but themed effectively so that brand recognition is not lost on better known brands. 

Print Resolution

As mentioned before, large format is usually printed at lower formats, BUT if at all possible, design your artwork at full resolution at full size. If not possible, work at no less than 25% of the original size, but still hi-res, say 300dpi, which will allow the quality to still remain effective on the large format prints.
