1) Majority of my images are not sharp enough. I use 300dpi in photoshop. How do you solve this issue, do you use specific size and resolution?
2) Printing quality is not the best, I tried to print flat black pictures and I can see like little dots or bubble on it. It's fine for matte cases but unsuitable for glossy. I use epson xp-315 printer and cheap sublimation ink which I bought on ebay for 30 pounds. Is it because of bad quality ink?
