Photoshop how many pixels per inch

Remember we have as many designers reading this as we do photographers, and print design is my background at an agency and for magazines, not desktop printing. And BTW, the software here holds new comments for approval, there was no need for your rude comments in your second comment. You jumped to a second conclusion. Both you and Colin are wrong in this. Pixels are not dots and dots are not pixels.

The average DPI for print is not It is DPI dots per inch. DPI defines the quality of the print. It is disappointing that Colin appears to be confused about his own use of terms in a teaching article. That means it use 8 horizontal dots in each line, and print 8 lines to get a single pixel. Thus there are a total of 64 different dots of ink that make up the colour of a single pixel.

That mentality was the inspiration for this article. And you are correct, you are giving the printer pixels, not dots. I just reduced the percentage size of the image until a handheld ruler became accurate with the photoshop rulers. It only took three tries to narrow it down accurately from an initial visual.
