I have to give a presentation this week at work, traditionally people have used power point or a .pdf
I was going to create the document in corel then go down the .pdf route,
I was really wondering because I need to shrink the document as much as possible as to what resolution images ought to be? currently I have tentatively turned them down to 200 dpi but the file is still huge, anyone have a recommended size?
the other problem I have is that some sheets are portrait or odd sizes, they seem to look ok in adobe .pdf reader in full screen mode so will pressumably be ok for the projector?
Now I know alot of this depends on the projector itself and to be quite honest I dont know anything about it, I think its fairly standard and its one of those that you plug into your computer and it beams the image onto one of those roll down/roll up screens.
thanks in advance
In practice, it probably doesn't matter too much, especially if you are using mainly vector objects in your design. If they remain as vector objects in the PDF and you are running the PDF viewer in full screen mode, they will projected at the native resolution of the computer controlling the projector, without needing any special action.
So, more important is to know the aspect ratio (4:3 or widescreen) and make sure your design page is a landscape page in the same ratio.
Stick to vector objects as far as possible.
Any bit images will be resampled to fit, but provided your page size is somewhere near the same pixel size as the projector it will make little difference. I've yet to see a projector that's focussed well enough to tell whether resampling is occurring. But if you want to be sure, http://www.projectorpoint.co.uk/Projector-Resolution.htm has some example resolutions. You can set the CorelDraw design page size to one of those sizes (using pixel units rather than inches or mm) and create your bit images in photopaint to the exact pixel size.
Harry, you're back on the case
unfortunately, most of the presentation is .jpgs or .pngs and I have found that turning any vector drawings into .jpgs or .png actually reduces the overall size of the document, I think this is mainly because we're talking about very complex vector drawings that have been exported from autocad, and it seems corel doesnt seem to like to handle these drawings too well.
From what I understand, you're saying the projector will squash or resize the images to the same shape of the projector?
that's abit of a nuisance because alot of my pages are either portrait or of a strange ratio, ie some are square and some are photographic panormas so have a much narrower thin resolution.
What would be your advice on this? some pages I should state I am completely unable to reorientate (those that are portrait) although I guess with the odd shaped ones I could put them on a standard landscape page and fill the empty space with a filled rectangle?
I guess the only way to know is to either test it or talk to the IT guys at work, but the presentation is wednesday and theres ALOT to do....
oh woops, I've just realised I've out this in 'photopaint' instead of Corel Draw...
