--- Quote from: deano7 on February 24, 2010, 02:39:46 pm ---Is 720 DPI too low of resolution? I am concerned that the last guy said it didn't look good up close. It is a jukebox and people will be standing right up to it with the marquee literally 1 foot in front of their eyes. I am sending it in a high resolution and the marquee is only going to be 9"X 20". What do you think? --- End quote --- I can take a picture of my marquee from 1 ft back and I'm sure it'll show that the marquee "looks great"... My point is that there's no way you can tell, at the resolution that Ginsu posted at, whether the resolution is sufficient for your needs. Unless the image is a close up macro shot, there isn't enough magnification to tell. 720 DPI is not a terrible resolution. ( Maybe I made it sound worse than it really is. ) 720 DPI might be low resolution for an inkjet considering many now advertise up to 4800dpi. It doesn't mean that it's not sufficient to produce a reasonable print. Depending on the half-toning algorithm, 720 DPI inkjet is ~65-85 lpi. It's possible to go higher in lpi, by trading off resolution for gradient levels. When I get home tonight, I'll post a picture of the printout for my bezel info (which is the same print job as the marquee). I should be able to get a macro shot with a ruler for reference, and you can decide if 720DPI is sufficient for you needs. My guess is that for most marquees, it's not an issue, but only you really know for your own application. I'll try to provide the info, you can decide for yourself. |

I think you mean 72 dpi? Correct... 720 dpi at marquee size would be a marquee at 6480 x 18000. Most printers you wont see a difference over 200dpi. I printed all my sideart, marquee and bezel here at work (see sig for pics )on a Hp DesignJet 5000 42" Plotter. I created the files at 300 dpi, but the side file size was getting a little big... about 9000 x 18000, which is HUGE.... so I reduced it to 200... I also plotted it out at 150 and you cant see a difference... Good luck.. Camper |

Most printers you wont see a difference over 200dpi. --- End quote --- Actually, I do mean 720dpi, but I'm referring to the printer resolution. I believe the printer is ~720dpi. This is an educated guess based on what I see in the output, as I don't know the actual printer that was used. ( I can tell you it was an industrial sized printer as I also had a 5ft x 4ft vinyl print made. ) A 720dpi color inket prints around 65-85lpi. Applying Nyquist theory of 2x the highest frequency, this gets a recommended 170dpi for the artwork. For DTP, a 1.5x ratio is also commonly used which would be 130dpi. In my case, I supplied vector art, but if it was raster, I'd have the source at least 130dpi, preferably 170dpi for this particular printer. |
