Printing image...

I dont know if this has something directly to do with photoshop but i dunno the right place to post this so here it goes:

i want to print a/some wallpapers...they at max are 1600x1200pixels...i looked at some posters in my room and they are about ~100cm high, ~70cm width...

to have some kind of feeling of what could be the final result i opened photoshop and in IMAGE SIZE i saw that bellow in the form there is a thing called "IMAGEM SIZE" where it says that my 1600x1200 pixels image is 56,44x42,33 cm's...this means that if i printed the image just like it is it would have that size? or is it a something else thing?

Good Question. Pretty complicated topic though.

Yes, and No. You can print stuff out at 72 dpi and it will be just that 72 dots per inch. - pretty lousy quality - especially text. BUT - your printer prints at a certain resolution that effects that, too. It tries to interpolate or resample for you if you're not careful.

my advice, turn off the check box "Resample Image" and size it how you want it. I'm guessing 8x10 or 11x17 would be okay. Maybe even smaller, depending on the desired resolution.

Typically, the bigger you go, the lower your resolution can be. (we print billboards at 9 dpi sometimes, and they look great) - all due to viewing distance.

was that confusing enough? anybody have anything else to add? or did I jack that up somehow?

hmmm the bigger the image is isnt the better quality print ill get?

ill print that in some place that have laser printers so it will be a bit expensive :\

Size doesnt always count (hehe!) Ahem, your resolution will determine the print quality. At 72 ppi, you could be wasting money getting them printed on an expensive laser printer.

ahh...where do i see the ppi? i know the default is 72ppi for creating new pics in photoshop but where do i see that in other pictures?

bah im such a dumb...in IMAGE SIZE it says it...but look...for example see this image:

this image is 1600x1200...it has 72ppi....if i put it to 100x70cm it will have good quality?
i am not getting what u mean by "having less ppi is better"...u mean that to the human eye have 72 or less is the same on a room wallpaper and that is much cheaper have about 9 ppi instead 72?

ppi determines how may pixels take up an inch space. The more the better. But monitors display at 72 ppi so no need to use more for web work. But if you are printing out something, that would be in dpi, which is roughly the same as ppi. So if your ppi is 72, then you will print roughly at 72 dpi resolution, (correct me if I am wrong =\, I'm still trying to get this all figured out.) which would mean not so good print quality.
If you are 'increasing' the image using photoshop, then you are degrading the print quality even more.
Basically, if you are getting an image off the web at 72 ppi, and wanting to print these into a 'poster-like' quality; it won't look poster like, that is not set up to make nice prints. You would need to find a higher resolution version to print nicely.

But if you decrease the image considerably, it might work.

300 PPI is a pretty good for printing. That's correct I think Marble.:p

right.... an image that is 1200x1200 set at 300dpi will print out as a 4inchx4inch square.. if you se it as 1200dpi it will be 1 inch and so on... however you can work in 300dpi with a 1200x1200pixel image and force it to print 8inchx8inch, but it will then be at 150dpi resolution.

got it?

Hey no onw sais it need to be in CMYK (not RGH wich is used for screen...

If you done these wallpaeprs try to redo them in high resolution (330 150 youdecide but the more you bost you rsultoj the more rescouces the image will take... Trying to print form a image who as been created for on screen presention will never show the smae qulity as sometin made for high resolution...
