This list doesn't make a lot of sense, I think. The 'in-eye' density of the pixels/dots varies wildly if you graph it out: I'd say that generally you wanna strive for a PPI density of at leastDPI = 200/(distance in feet) So 1 feet = 200 PPI (phone in hand) 2 feet = 100 PPI (laptop/desktop) 4 feet = 50 PPI (no idea what…
That image you posted has enough pixels for a much larger print. Much larger. A 300PPI print already has smaller pixels than a human hair. You don't need a 9600PPI image. You need a 300PPI image printed on a 9600DPI printer so you have 1024 color variations. As to what is better? Well, if you're going to print at too high…
If something is bigger people are looking at it further away. When you read a magazine, you are looking at it from a foot or two away, when you look at a 36x48 image, you are 4-8 ft away. Billboards can be as low as 9 dpi for larger ones and still look good. So the bigger something is, the further away the viewer will be,…
this is wrong - DPI doesn't work like this. And a colour image is just four black and white images. The DPI you send to the printer is not the DPI the printer prints at. Most printers will use a line screen to convert your pixels into a number of separations (eg channels). The line screens are essentially black and white…
That printer prints at 600x600PPI, just like the Xerox. But because it has 12 inks it has wider color range in the same area. The Xerox has 8 dots, which means 9 possible values for a color (0%, 11 %, 22% etc.) and 4 colors (cmyk) so it has 9^4 = 6561 colors per pixel (at 600PPI). The Canon Prograf(btw, thanks for not…
I didn't say anything about how printers print hehe. Actually, most home printers offers a print resolution of 9600 x 2400 dpi, that's a insane amount of detail (ppi are different, so it's a marketing number :S), so the bigger the resolution of your image, the better (but it depends of the size!!). A 3000px image looks…
