you may want to check into this, it has worked well for me:

thank you all. i guess the nearest neighbour is the way to go. again cheers for all the help.

72 dpi is hard to blow up unless its a big 72 dpi image.
I've had good results with the following technique...
1) Use nearest neighbor to get it to 300 dpi, but don't force the size larger - ie: deselect Constrain Proportions
2) Go up in incriments if 110% and use bicubic smoother. I don't know why this works, but it seems to do better than going up all in one shot.
Set up a photoshop action for step 2 and it will go faster. Keep going up in incriments of 110% until you're at the preffered size.

i think we're talking about two different things here. pixel oriented and image oriented. i know that lowing up a lores jpeg of whatever will become very very ugly. but with pixel it's a different issue, it's not a photo and it does not need photoquality.
i'm going with stew's thing though.
my guess is that eboy does it the same way. worked originaly in a 72 dpi doc, pixel by pixel and then blowing it up to 300 by using nearest neighbour.

I haven't actually tried this but there goes...
Try changing your monitor settings to a very hi resolution and taking screenshots from that. Turn your settings back to normal and change them to 300 dpi in PS without resampling the image.Btw, I didn't read though the replies so if someone suggested this already... well, it's a good little trick anyway.

I dunno - I reckon those pixels in the eboy stuff are probably more like a few pixels, rather than just one.
The best way to see what it'll print like is open up a big 300dpi blank document and just drop your scan in, then it'll come in at the size it'll print at 300dpi, then obviously any sizing up you do will lose quality in the print. you could probably go down to about 200dpi without losing quality. Trust me - 300dpi is print quality, 72dpi will look like a really bad jpeg but on paper. To be honest I've never understood how they print 'pixel' drawings. I suppose if you could get the pixels to fit exactly in the 'grid' of pixels at 300dpi it might work, as then the edges aren't blending into the rest of the image

Keep the res... it's more readable cause it's larger and pixelate as a web page should be.

so the test i did is just not showing it right?
i have those eboy posters and it's all pixel, if i resize a screenshot / pixelart in photoshop it becomes blurry (unless i use stew's suggestion) but then what's the difference between that and the original 72 dpi file? or am i just too stoopid to understand?
- CharlesChester0
300dpi.
It doesn't come out like sharp pixels just cause you blow it up - if you print at 72dpi, it'll look like a bad jpeg.
- rabattski0
hmmm... but how does eboy does this for instance?

is it a 72 dpi file or a 300 dpi file?

like i said, this was a couple of years back, so i'm not sure what steps i took. i might have modified the screenshot in ps to print fine. good luck!
- CharlesChester0
300dpi to print - no more, no less... even if you scanned an image at 72dpi - you'll have to resize it... but it'll lose quality. It's like trying to blow up a .gif to A4 and print it "cos it looks good on screen"

By scaling it down in physical size (in your layout program) you are essentially rezing it up.
You could alos resize in PS
Either way the equation is:
(Actual Image Resolution) / (scale) = Effective Resolution

can you chew on George Bush's arse without it leaving a nasty taste in your mouth?
- rabattski0
greedo, the screenshots i have are jaggy anyways (classic os). so that's not point.
stew, someone else suggested that as well and it does work well, it doesn't change the look but it's at the right resolution.
i think i'll go with your suggestion.thing is, i tested it with slamming a 72 dpi screenshot in xpress, exporting the page as an eps and reopen it in photoshop and it just looks fine, it even looks fine if i blow the image up to a 1000% (in xpress). but does this really count? does that represent real printing?

if you are going to res up using nearest neighbour so that the pixels are visible, do by doubling or quadrupling the size, otherwise you get strange things happening with line thicknesses and type.
- stewart0
yeah right tim!
- tim5250
i should note that the screenshots were printed at small size(2x2)
- stewart0
me, personally i like it when you print it large you can see the pixels.
i would convert it to 300dpi, but scale it with "closest neighbour" (?? "nieuwe beeldpixels berekenen - naaste buur" you know ;) )
