It looked sharp on screen but printed blurry
Not enough pixels for the size you are printing. Screens forgive low resolution; film does not.

What is actually happening
A monitor shows roughly 72 to 110 pixels per inch, so a small file looks perfectly sharp on screen. Print stretches those same pixels across a much larger area — an 11-inch front print at 300 DPI needs 3,300 pixels of width. Below that the printer is inventing detail that was never in the file.
How to fix it
- 1.Work out the effective DPI: pixel width divided by print width in inches.
- 2.Aim for 300 DPI. Between 250 and 300 it prints but fine detail softens; below 250 you will see it in thin lines and small text first.
- 3.If you are short, print smaller or upscale the file before you send it.
Not sure this is your problem?
The check looks at everything at once — edges, transparency, resolution, stray pixels, garment contrast — so you do not have to know which one to look for.
