Good but printing quality isn't as bright as usual

The printing quality is usually brighter and more saturated. They look a bit dull and faded. When I showed them to my partner he said "these look like they were left out in the sun." I realize that my designs are lighter pastel colors, but I was still expecting the stickers to look as saturated as the artwork does and they don't. I usually order 3" to 4" die cut stickers and those always turn out amazing, so my expectations were high. The sticker paper for the sheets is great quality though, and they feel as durable/water resistant as any other sticker I've ordered in the past. I definitely still like them but not sure if I'd order the sticker sheets again for pastel designs.
