You can now source self-adhesive badge sheets that will print in a standard laser printer and produce full colour double sided badges. I tend to use an A6 badge size which prints front and back on a single side of A4 sheet. You then simply peel the badge off, fold it back on itself to stick the front to the back, and then attach direct to the lanyard. It’s a quick process which I have used on events with 1,500+ delegates without causing excessive queuing.
There is some wastage from the backing sheet, but this is just paper and so can be easily recycled. The badges themselves can also be simply recycled by delegates when they get home. The badge in the picture is printed in this way.
For smaller events where I pre-print badges I use heavy-weight card sheets. By using the data merge feature in Adobe InDesign (similar to mail merge for MS Word) you can create a full-colour, fully-designed badge artwork .pdf file complete with delegate details direct from your registration database. A good local print shop can then print to the card sheets, trim to A5/A6 badges and punch holes for the lanyards. If you want to create stunning badges it’s a great system. It’s also cheaper than buying badge holders and perforated badge sheets.
