I want to print some of my images and want to know how many pixels make an inch. Is there a chart or something that would tell me?
Thanks

Screen resolution is 72 pixels per inch. But print resolution is determined by your printer, not your monitor. So if you have an image thats, say 144 pixels high and your printer resolution is 100dpi, itll print out at 1.44 inches high. Now, not to complicate things, but if you take the image and export it into a program such as Pagemaker or QuarkXpress, then the resolution will be determined by what sizing you give the image. Taking, again, the example of the 144-pixel image above, if you import it into Pagemaker into a picture window thats 8" high, itll indeed print at 8" high but with a lot of fuzziness since there isnt much image information to work with.

I found that an image of 1500x2000 (Width x Height) gives a nice and sharp picture printed on A4 paper format, with narrow, even margins on either side of the page and larger margins at the top and bottom of the page with enough room for title and subscript. Divide the above figures by 2 and your printout will get less sharp, multiply by 2 and it will get sharper. Higher multiplications may result in loss of detail of color or bleeding. Depends on your printer too, i guess. Im using a HP Deskjet 930C with HP Two-sided Photo Paper, Glossy/Matte.

Thanks so much for the help. I'm hoping that most of my images will print out and fit at least an 8x10 frame so I can give some as Christmas gifts.

Work out how big you want the picture, in inches, then multiply by the output resolution you want - Epson recommend 240DPI, try that or somewhere between 200DPI and 300DPI for starters - and that gives you the size you want in pixels.

Just from my own experience, I print my stuff on a high-end color printer that uses the Splash rip system (Its a 35 grand printer, and I get to use it at night when the place is closed). I figure on the basis of 100 dpi, and Ive never been disappointed with the print quality, even on high-gloss paper. Anything more than 250dpi is pushing things into the silly region, to be frank; even high end art magazines rarely go over 300dpi.

Strictly we should be talking about PIXELS-per-inch, to avoid confusion with the dpi setting of our printers, but no matter how many times I am told I still slip back to using dpi as the general term.

I was talking image pixels alright. And my HP 930C prints at 600x300 (min.) and 600x600 (max) DPI. Normal quality laser printer print at 600 to 2400 DPI. And BTW, the printing process of magazines cannot be compared with household printers, those pages get photographically burned on the paper. Maxx
