How to customise it
Every word is editable, from the title to the signature line. Choose A4, US Letter or A3, in landscape or portrait, and the layout rearranges itself to fit. Prefer another look? Switch to the Lab Blue or Violet Assay colour scheme, or pick any colour you like. Fonts can be swapped too; the defaults are Public Sans and Atkinson Hyperlegible. You can also upload a logo or a photo and place it anywhere on the page.
Printing tips
A smooth, bright white card stock (about 65–80 lb cover) gives the cleanest finish. Download the PDF at the paper size you will print on (A4 or US Letter) and set the printer to “Actual size” or 100%. It fits a standard certificate frame or a document folder.
