    Printing made simple.

    This is the simplest way to figure your painting size or image size for printing.
    Take the length of one side.
    multiply it by the dpi you want. (300 for example) the best is between 200 and 300.
    (anything over 300 dpi is hardly discernible with the human eye and way too saturated for ink jet printing)

    example: you want an 11 x 17 inch print at 300 dpi output.

    11 x 300= 3300
    17 x 300 =5100

    your canvas size should be 3300 pixels by 5100 pixels

    example no 2.

    you want a 16 x 20 inch print at 200 dpi.

    16x 200 = 3200
    20 x 200 = 4000

    your canvas size should be 3200 pixels by 4000 pixels

    Yes folks it is really that simple.

    Hi Gzairborne,

    Thanks a lot!

    Quite adequate for my printing requirements.

    I'll do some calculations to get A4 and A3, those being the limits of my home printers.

    Ummm, I don't see why this is helpful at all.

    Simply set your H and W (use the drop down next to the space to set what you want, like cm,mm, inchs etc) then type in your print res. By doing what
    he says, your going to get unnecessary slowdown and wasting time.

    Phil,

    The printable area for A4 is 8 by 10.5 inches
    The printable area for A3+ is 12 by 18 inches
    The printable area for A3 is 11.4 by 15.4 inches

    (yeah, it varies a bit among printers but approximately)

    so A3 =

    11.4 x 300 = 3420
    15.4 x 300 = 4620

    A4 =

    8 x 300 = 2400
    10.5 x 300 = 3150

    Hope that helps.

    Yep, artrage does make it simple. Just type in your canvas size and select your dpi output.

    This just helps people understand what is going on. Because they will invariably open up artrage and paint at the default dpi of 72 dpi. and then not understand why the printed image comes out so small or doesn't hold quality at larger sizes.

    If someone paints an 8 x 10 inch painting at 72 dpi the pixel dimensions would be 8 x 72 = 576 and 10 x 72 = 720
    at 300 dpi it would be 8 x 300 = 2400
    and 10 x 300 = 3000

    artrage opens in the default of 72 dpi and 1680 pixels width and
    1028 pixels high... so:

    if folks tried to print that image it would yield:
    @ 72 dpi an image 23.3 inches by 14.3 inches

    @ 200 dpi an image 8.4 inches
    by 5 inches

    @ 300 dpi an image
    5.6 inches
    by 3.4 inches

    yes larger images do require more processor power.

    if you set your canvas size to 10 x 15 and 300 dpi output you will be working with an image that is actually 3000 x 4500 pixels. Got to be that way.

    If you don't believe me just go into Photoshop type in 10 by 15 for the canvas size and select 300 ppi for the resolution and see what your pixel dimensions are.

    Yes, you both are right...
    But turtleman has a point....

    Why calculating in pixels when you can just set dimensions in Inches or centimiters ? When you convert it, yes it goes from
    10inches in 72 = 720pix
    and in 300 dpi to 3000 pixels.

    Point is, no need to calculate, just show one how to set DPI and measurements for the image.

    But i find this useful information....bunch of times i need to know how big will an image be on my A4 paper if is 3500pix (for example) in full quality (300dpi)....and now i can do that without photoshop...nice !
    No ambition makes you normal.

    Question file formats for printing

    I appreciate the help with sizing. I am also wondering if anyone can suggest a file format that will produce the best commercial printouts.
    I know that jpegs look good on screen but when printed are sometimes not as rich in color. Can anyone suggest a good printable file format that shows off artrage paintings the best?

    Jpgs are horrible for reproducing, it always compresses, PNG is what i would choose, no compression and it does a great job, if ArtRage had the TIFF file format i would use that too, maybe even over PNG, hen import photo's from my camera, the 1st thing i do is save copies of them in the TIFF format and work with rather than the original JPG, but i suppose others have the preferences as well

    I'm not sure what printing companies require
