The $160.00 is a one off charge for making the emboss plates and setting the printing machine and then charged per card
Blind embossing is where two special printing plates are made to create a 3 d image on card or paper
where it gets sandwiched between the 2 plates under a lot of impression to create the text push up for emboss, or down for debossing
Embossing is same principle but where it pushing print or foil up so when says blind embossing means its only the image pushed up through the card or paper used, this process is perfect for wedding invitations.
this church book cover used same embossing plate for invitation but had another plate made for dates.
to save money you can use same emboss plates for invitations and church books ask us how.
