working in graphic design

hey all,

ive just got some commerical experience (actaully working on the item right now), its a invitation card and also a poster/ advert for a charity advent to do with unveiling of a glamour model for a hair stlyist. so its gona be 1/3 of A4 when printed (99mm by 210mm), but im using a dpi of 1200 and its taking up over 700meg of ram, and this got me thinking what must it be like for graphic designers who design large posters like billbaords.

ive seen a boxx system for 51k with 32GB of ram, so if i were serious about this kind of stuff would i need a system like that? (maybe but ott, but i hate working with lag etc…)

Im not getting ahead of my self here, but i do plan on setting my own studio up so if i did i would probably be doing stuff like that, so any information about graphic designer systems, courses, books, websites would be helpfull…ill also see if i can put the poster up here for you’s to look at (and probably laugh…), since i own the copyright :smiley:

billboards are only a few dpi, maybe 20 dpi or something.

they use nothing more than doing an A3 @300DPI


ah ok, well that aint bad then. hmmm wonder why i was asked for such a high resolution.

because of the size you would kill the rip with a full resolution print file.
also because of the size you do not need that resolution because you will
view it mainly from a distance.

that also saves money on the ink as well.

1200dpi is perhaps the resolution of an imagesetter or
a platesetter to make the lithography plates.
Only binary(not gray scale) black and white line art is
demanded such a high resolutin.

Usually for print (especially below A3) you won’t get any higher then 300 dpi.
We create our A1 posters at 300 dpi anyway.

Yep, billboards vary from 20DPI to around 120DPI, depending on the viewing distance, and if you ever look at the billboard their not that fancy - a photograpth with text alot of the time.

What they do /can do is work in a lower size such as the original image size. Do all the designing /placement then blow the image up to size with interpolation means. With the fact that thier printing at 20DPI the original image would print very big anyway (15 times bigger than it’s 300DPI counter part)- with a little blowing up they have full scale image hassel free.

1200DPI is pointless for general, full colour prints. The only time you realy need that high a resolution is for artwork and alike which is generally scanned anyway… I expect the people who told you to use 1200dpi dont know jack ^^.

Of course, 1200dpi looks so much better than 300dpi.
