What does "designs" mean?

For some products we offer the option to have different designs printed within the same order. On the product page, you will see a Number of Designs field. Here, you can select how many different pieces of your artwork you'd like printed. For example, you may have 2 different pieces of artwork for an A4 print and you'd like the designs split into 5 of one image and 10 of the other. This would count as 2 designs. The charges for these additional designs vary due to the processes involved in creating them. Each product will show the design costs in the Number of Designs drop down menu.
