Black Print Test Sheet

I was not able to find any simple black print test sheets online, so I made my own. It consists of three columns. The first is entirely RGB #000000, the second CMYK 100, 100, 100, 100 (so-called “rich black”), and the third is entirely RGB #2A2A2A. Note that the 400% rich black may not work well on inkjet printers (it can cause ink saturation and smudging). It should work well on laser printers, however.
