Historically, embossing has been one of the only possible ways for the visually impaired to both read and convey images. That's why this method is also called 'blind printing'.

For embossing, a metal die needs to be prepared in advance. Depending on the size, making metal dies costs 100-400€+VAT. This means that for such orders, the need for repeat orders is important; otherwise, the order becomes absurdly expensive for a one-time use.

Another difference is whether the pressing is done inward (down) or upward from below. Pressing upward adds another 30% to the price because a counter-die is required in the same way.
