Visio: Fuzzy text

July 16, 2010

I created a Visio drawing the other day, and noticed the text was fuzzy on screen (‘fuzzy’ is a technical term!). I checked all the font settings, but nothing appeared to be wrong. I saved the drawing as a PNG using the default settings, then printed it out. It was awful. The text was so fuzzy it was unreadable at the small font size I needed to use.

So I went back to the PNG settings, which you see when you ‘save as’ PNG, and fiddled with them a bit. What worked was changing the output resolution to Print (not Screen), with its default 600 pixels/inch setting — that was all I had to change to get much sharper text.

I tried a Custom resolution setting at 1200 pixels too, but that made very little difference to the print quality of the PNG — all it did was blow the file size of the PNG out to 5 MB from about 500 KB (the 600 setting increased the file size to about 1 MB).
