QSN about TIFF and JPEG

[chlai]

Dear experts,

I am printing a banner of size 1.5 by 9m.

I have the following three files

1) 150 dpi JPEG file saved in RGB at size 1.5 by 9m
2) TIFF file at size 0.75 by 4.5m
3) 72 dpi JPEG file saved in CMYK at size 1.5 by 9m

Which one will produce the best resolution? i.e. clearest print.

Tks in advance!

what is the dpi for Tiff format?

if possible, give tiff format bcoz tiff is lossless quality.
whereas jpeg is lossy quality.

Jpeg keep resaving will deteriorate the quality.

2ndly, tiff able to retain layers files.
but jpeg cant.



Option 3 is redundant, as saving in CMYK will increase file size and only 72dpi.
Minimum for large format size dpi should be 100dpi.....(of coz, you need to see the source of the image quality)
if the source is poor...pumping up the dpi is useless.

and if you are printing banner using large format inkjet printer, RGB will do.
CMYK will appears abit darker.

the TIFF is saved in 300 dpi but the size is 0.75 by 4.5m.

I need to print double the save size which is 1.5 by 9m.

tks in advance!
