Large Size Printing

slmka · 20th August 2009

Hi,

Not sure should post here, but I have a PNG image (Computer CG) with the following information:

Width > 4116 pixels
Height > 2768 pixels
Bit Depth > 24 Bits
Horizontal Resolution > 299 dpi
Vertical Resolution > 299 dpi

May I know what is the max recommenced size I could print if I sent it out for large format printing?

Thx

Open up your file in photoshop, convert it to 300dpi and change ur dimensions to cm or inches or to whatever you prefer. turn on rulers and you can see the output size.

assuming without resizing and up-close photoquality print, one can take 180dpi as image res to give about

width ~ 22.87in, 58.08cm
height ~ 15.38in, 39.06cm

for banner size viewing (i.e. looking at it from say more than a meter away), one can take 75dpi as image res to give about

width ~ 54.88in, 139.40cm
height ~36.91in, 93.74cm

if your image is perfectly sharp, and being a CG image I would assume so unless the blurness is intentional, using Photoshop one should be able to upsize the image up to 4 times, with some sharpening, to reasonably acceptable quality... which would give, at 180dpi,

width ~ 91.47in, 232.33cm
height ~ 61.51in, 156.24cm

or at 75dpi,

width ~ 219.52in, 557.58cm
height ~ 147.63in, 374.97cm

ymmv
