Print quality has definitely changed

I’m not sure what about the printing process changed. I ordered some prints when posters first became available and the quality was fantastic. Everything was super clean and color correct but unfortunately this last batch was not the same case. The image turned out pretty blurry and I know that’s probably a resolution issue but in the past the past I’ve been told when a image is to low but I didn’t get any warning of that this time. The other main problem is that there are clear print lines running through the image that are not there in the original art. I’ll keep using sticker mule for stickers but I can’t trust the print quality of the posters anymore.
