Compared to proof, lacking crispness/clarity of line and whites are dull (in image and text).

I have ordered about 6 stickers to date and generally compared to the proofs, the printed stickers delivered are lacking crispness/clarity of line and the whites are dull (in image for highlights, and text). The bear sticker arrived yesterday and the whites are not there. Overall, the image is greyed out; the light blue in the water in the proof drops off to a grey blue in the sticker; the red orange I see in the proof is missing that "pop" on the sticker. Even the text does not have the brighter white and sharper edge I see in the proof. The bear's nose especially, is clearly missing the white highlight I make sure is in the original file which I see in the proof but not on the delivered stickers. If there wasn't a proof for comparison, the average person would be satisfied - but I am not. Perhaps a reprint would help, which Stickermule has done in the past with my orders.
