The problem with Cafepress t-shirts is the process they use: sublimation printing. This is only really suitable for white shirts and for a more durable print it needs to be sublimated onto a 50/50 polyester shirt. The problem there is those type of garments are really naff.

However, sublimation techniques are excellent on things like mugs, mousemats, jigsaw puzzles etc, as long as they’re white backgrounds, which they usually are.

We’ve just purchased a digital printing kit which will allow us to offer customised versions of our designs but this is more suitable to flat colours, text etc. The plotter cuts out the design and then it is heat applied to the garment. The results are brilliant but, like I said, best suited for flat colour or text designs e.g. silhouettes, slogans etc.

Our new site is under construction and we’ve also decided to print onto American Apparel shirts – best quality, best cut.

Maybe I should start a blog on t-shirts!

It all depends on how much you’re willing to mark up above the cost of producing the shirts. Without knowing any of your target demographic or how many shirts you plan to make, i’d venture a guess to say 5-10 dollars US each.
