Large format printing of images with small file size?
I’m sticking my neck out here asking what probably is a very naive question! But, as I’m not into large format printing, I’m sure you’ll excuse me 🙂
I’m have no knowledge of graphic formats used for large format printing of such thing like banners and signs etc. So I’d be grateful if someone could enlighten me, perhaps from the following scenario:
A client bring you a picture in .jpg format. The file size is, lets say 700k so not exactly very hi resolution. If I was to blow that image up significantly to the output size required, it would probably look horrible!
So how is it done maintaining the quality?
Cheers

quote :So how is it done maintaining the quality?basically its not, there are some programs to help like blow up but if its not much good to start with.
if any doubt print a foot square at the full size.
i aways ask for the original file not the one that the customer has played with.

If you don’t start with quality you will never achieve it.
many things effect the amount the picture can be scaled but normally work on no more than 400 – 500% if 300dpi and if it’s a good quality to start with.
It also depends on what it’s for and where it’s going.
All things you will learn along the way 😉

Low resolution images can be improved by re-sampling. This does not add more detail but will remove the pixellated effect seen when a low resolution image is enlarged.

Just to add to Phil’s, advice
it all depends really on the size of the finished image, and at what distance it will be seen from.
you will never resample a 50kb image to be acceptable as an 8 x 4 print
unless viewed from at least 50 metresPeter

John, I have had some incredible results using Photozoom Pro. http://www.benvista.com/main/content/co … ozoompro_1
Try the trial, you will be surprised how good you can make even internet images. -
Peter, there are a few people on the forum that use photozoom, it has been talked about before and had some good reviews by forum members.

Thanks for the replies chaps.
I understand how vector graphics can be resized without loss of quality so what proportion of your work would be solely vectored based and may I ask just one more question – what does RIP (in the print world of course) refer too?

i actually studied this for large format printing…
our rule is when it is at actual size, you got be between 40-100ppi (dpi)
Thats pixels per square inch, in corel u can see this when blown up as its in the information bar.
