File Size Problem

Hi

I am looking at designing a wrap for a Merc A Class.

The file I want to use is ending up at over 1 GB when I size it to fit the vehicle. What is the lowest resolution I can go down to without it looking really bad ?

Cheers

Adam

72 dpi actual size is usually the lowest most would go to, but can depend on the image on what quality you are expecting. and of course the printer settings.
1gb is actually quite small for a wrap I would say

also depends on how the colours work within the file, for instance a zebra wrap with hard black to white would look terrible at very lo-res 50-80ppi but a grass/nature hillside would look fine.

Thanks for the replies.

The 1 gb was the file size for one side before clipping to the shape of the vehicle. It just keeps crashing Corel. I have reduce the image to fit on here and attached.

Hi Adam,

Do you have photoshop?

There is a 'save for web' option that can sometimes massively reduce file size. (Although it says 'save for web' there is no reason why you cant use it for other purposes - I often use to shrink files for sending by email).

It gives you various options to save such as GIF or JPEG.

You can often keep the number of pixels.

Wont be appropriate every time but worth a try.

Martin

p.s. it is under 'file/save for web and devices'

Martin, I dont think that will be an option to save for a wrap,
"save for web" optimise's the image for viewing over the net, reducing the size and resolution accordingly, yes it will save the pixels, but only if the image is very small to start with,

try as a 25% finished size @ 300dpi. Save as a tiff file with LZW compression on.

Don't save as a jpeg or giff files, these are for web and email use really.

Also if you have the file in layers (photoshop) then save as a flattened file so it will save you a lot of mb and open quicker. But save the flat vesion as a copy so you have the layered file as a back up if you need to go back and amend anything in the document.

When I did the last roof wrap on a MINI Clubman (7ft long) the flattened tif file was approx 400mb.

hope this helps and I'm sure others will have a different approach to the same affect ;)

There is nothing wrong with saving as a Jpeg but with no compression. This will make the file smaller. When viewing from a distance there is no need for these huge files.

Martin, Jpegs are RGB and coming from a designer/litho print background I would only use jpegs for web activity as they loose to much info when saved out - but that's just my opinion.

I would rather have a larger file to rip and have a very sharp printed image than a compromise on the quality - but as I say thats just my way of working ;)

I did a test once with a photo blown up to 3000 x 2000 and saved as a Jpeg it was 17 megabite and saved as a tiff it was 155 megabite. both pictures printed the same.
