Hold on a sec. There’s some confusion going on here, perhaps only about terminology.
In the printing trade, “web” describes the paper feed method, not the printing method. A “web” press is one that accepts giant rolls (“webs”) of paper, as opposed to a “sheetfed” press that takes stacks of flat, rectangular sheets of paper. A web press can be offset, letterpress, gravure, flexographic, etc. (different printing methods). So, Gaudere, you’re talking apples vs. oranges – “web” is not the opposite of “offset.”
Now, perhaps you meant “web,” as in the www, where online companies offer “digital” printing, as opposed to offset printing. (These digital presses, I think, are essentially mass-output inkjet printers, but I may be mistaken.)
In the past, Vistaprint has printed all my business cards and postcards by offset printing – all top notch and high quality. That is why I recommended them.
That said, just last week I ordered some new postcards. I was surprised to learn after I placed the order that they would be printed on a digital – not offset – press, which upset me a tad. But now, this was a run of only 100 postcards. Everything I’ve gotten in the past, including business cards, was 250 or more. I suspect that runs under 250 get digitally printed. But I could be wrong. You may want to find out if they still do their business cards offset or not. If not, like Gaudere says, you may want to think twice.
But then again, for virtually free, how can you really go wrong?
