Next, copy-&-paste each of your sticker designs onto the Sticker Sheet Layout document, and arrange them in your desired layout. You can toggle the position layer on and off as you work for accurate placement.
Because the stickers will be die-cut, it's important to allow space all the way around each of the stickers to prevent any details being cropped. No design should butt up against any other design.
The next step is to colour up your stickers on the sticker sheet layout document but, before you do, you need to decide on the colours you are going to use. We want the colours to be vibrant and, because we don’t have the luxury of using spot colours, we have decided to use CMYK.
But, how you handle it is different to the standard CMYK working. For this sticker style we are sticking to pure CMY and K values – and avoiding any shades.
First, you need to organize your layers. On the layer palette, highlight all layers that contain your sticker art and sticker sheet info, and choose Layer > Merge Layers (Cmd/Ctrl+E). Rename the layer Black, and set to Multiply from the drop-down menu on the layer panel. You need to keep the layer top-most and, if you haven’t already, delete your positioning layer as suggested in step 3.
