Letters are cut out from coloured vinyl and stuck on to the acrylic sign. The end result will have a single background colour which is the colour of acrylic chosen and the text will be a single colour made of vinyl lettering.
Individual letters can be removed so you can reuse the acrylic sign but it's a tedious process to peel off each indivdiual letter.
Text colours and background can be fully customised, giving you the option to print in different colours, add illustrations etc. like the photo displayed. The end result is similar to printing on any foam board but is much sturdier as you are applying the printed material on to acrylic.
You can easily peel off the printed sheet. You'll then be left with a clean white acrylic sheet which you can sell or reuse.
