Hi Garry,
No tutorial needed since the way to render as "bmp" is all that is needed
and is in "render options" as well as the manual. Get your models done,
line
up the lights, set your "camera" and render to file as bmp. Tutorial
finished.
Print requirements depend entirely on printing device/machine. The people
who know exactly the optimum file parameters are the people (the
Printers)
who own and run each device. Go to those people for file parameters. This
answer could profitably stop right there but here's some more anyway.
So, render to bmp in RealSoft. Convert to whatever the Printers want or
let
them do so if needed. Render large file sizes since these can be reduced
if
necessary at little or no loss in sharpness (resolution) but small files
can
not be so easily enlarged without image distortions like pixellation,
etc.,
showing.
However don't be scared, if all you have is a small image lifted from a
website then that's all you have. Massage it as much as you can in
Photoshop
or whatever (I use PhotoPaint) and get on with it. The rule is simple
what
you are looking at will be what is printed unless someone messes up and
they
usually dont.
For USA Letter size paper and A4 the usual for Offset is about 300dpi so
files over 25 megs have more than enough information for top results.
DPI means Dots per Inch, it more or less means pixels per inch, therefore
with a calculator in hand you can sort out the dpi for anything you need.
A small confusion might occur if you dig deeper and come across LPI which
is
an old screen ruling term that Platemakers used when converting
photographs
to printed dots. These days just let the Printer worry about this side of
things since there are optimum rulings for each of the machines on his
factory floor plus, if the file is clean enough he might run stochastic
ruling which is fun. A good machine will easily handle 175 lpi but unless
it's newsprint, flexographics (on cartons usually) or silk screen dont
accept anything less than 133 lpi.
A small trick here is a frequency clash that can happen between a printed
image that has been printed using dots (LPI) and the reprinting of a scan
of
that again using dots ... the effect is called moire and can be a horror.
Best to press the "remove moire" button in PhotoShop after scanning
before
handing it over to the Printer ... except they will usually see what's
going
on and fix it or hand it back to you for fixing.
The file size is the total dot/pixel count multiplied by the number of
channels multiplied by the information type in the channels used ... CMYK
used Cyan, Magenta, Yellow and Black which is four channels and if it is
in
32 bit format then .. etc. RGB used three channels and is generally 24
bit.
Straight "Line Art", or Black and White is One Bit ... so yes, these can
be
very very high resolution with relatively small file sizes ... I usually
run
Line Art files at no less than 600 dpi. Greyscale is generally 8 bit ...
an
8 bit pixel object can carry 256 values of grey from white through to
black.
So, you might want the render to fill an A4, you will render to bmp as
mentioned. Your camera aspect ratio will be 1.41 (if the A4 is portrait
format and 0.71 if it's landscape) ... I use 1.5 and 0.75 so that I can
crop
the image if I want to ... anyway, rough enough. A long edge pixel count
of
8000 is heaps ... which more or less gives 8000 x 5600 total of 44 megs,
almost double the necessary and unless I've been really extravagant with
materials and lights etc the render times are easily sorted over night.
Don't worry about CMYK or RGB since most conversion systems these days
are
good enough and again either shift the file or have the printer do so if
need be. The RealSoft bmp's are RGB and I have only one service house
that
asks me to shift it into CMYK TIFs.
I use High Quality and Press Quality default specifications in Acrobat to
make pdf's a lot. The magazines that my clients advertise in and the
offset
Printers I use all ask for pdf's. These folk will be able to tell you
where
to download their favouirite pdf specs which you run in Acrobat from the
"job option" menu.
Sign writers are all over the place with what they need in file formats
however this is settling down a bit more now except for folk with older
gear.
But if you're doing the side of a truck then treat it as a very very
large
file until the people you end up using to do the job tell you to reduce
(resample) it downwards. Obviously if you can do the image on the truck
at
300dpi then it will look ridiculously sharp (high resolution) but the
file
would be several gigs. On the other hand if you havent rendered it large
enough then the beauty of RealSoft is that you can go back in and
re-render
it at a higher pixel count, no problem ... apart from the additional days
it
might add to the job).
Anyway, as I said at the start, talk to whoever is going to be doing the
Printing, believe me they want you to ask them since they want to be sure
you have every chance to dazzle your clients with a job well done and
this
starts with optimising the file to suit the machines.
I think that's most of the nuts and bolts covered. So far as TV is
concerned
refer to a post at the start of 2004 in reply to my enquiry, it had the
whole story. So far as feature films are concerned ... can anyone shed
light
on that ... nope, I'll just talk to the film folk when I'm ready to get
into
it.
Hope this is in the right direction, sing out if you think I might be
able
to help more.
